[0044] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application.

[0045] Currently, given that when the screen of an electronic device is damaged, the electronic device cannot respond to touch operations on the screen. However, the unlocking methods in the related technologies have certain limitations, resulting in low unlocking efficiency. To improve the unlocking efficiency, an embodiment of the present application provides an unlocking method, which is applied to an unlocking system. Figure 1 Schematic diagram of the structure of an optional unlocking system provided by an embodiment of the present application, asFigure 1 As shown in the figure, the unlocking system 100 may include: a first electronic device 11, a second electronic device 12, and a third electronic device 13.

[0046] Among them, the above-mentioned first electronic device 11 cannot respond to a touch operation on the screen. For example, when the screen of the first electronic device 11 is damaged, the first electronic device 11 cannot respond to a touch operation on the screen. That is to say, when the user issues any kind of touch operation on the screen, the first electronic device 11 cannot respond to the touch operation. For example, it cannot answer incoming calls, unlock the screen, etc.

[0047] The above-mentioned first electronic device 11 and second electronic device 12 may be a smart phone, a smart watch, etc. The first electronic device 11 can make a call with the second electronic device 12. In addition, the first electronic device 11 can be connected to the third electronic device 13 through a Universal Serial Bus (USB) data cable, and at least one physical key is provided on the first electronic device 11. The physical key may include a volume key and / or a power on / off key. Here, the embodiments of the present application do not make specific limitations in this regard.

[0048] Among them, the above-mentioned third electronic device 13 may be a desktop computer, a laptop computer, or a tablet computer. Here, the embodiments of the present application do not make specific limitations in this regard.

[0049] Based on the above unlocking system 100, Figure 2 is a schematic flowchart of an unlocking method provided by an embodiment of the present application. As Figure 2 shown, the unlocking method may include:

[0050] S201: When the first electronic device cannot respond to a touch operation on the screen, the second electronic device sends a call request to the first electronic device;

[0051] When the screen of the first electronic device is damaged and the user issues a touch operation on the screen at this time, the first electronic device cannot respond to the touch operation. That is to say, for the user, the first electronic device is basically unusable at this time. In order to implement the functions of the first electronic device, the first electronic device needs to be unlocked first. Here, in order to unlock, the second electronic device is used, and the second electronic device sends a call request to the first electronic device, so that the first electronic device can receive the call request.

[0052] The second electronic device here is an electronic device other than the first electronic device, and the second electronic device can establish a call connection with the first electronic device. In addition, both the first electronic device and the second electronic device can be of the same type of electronic device, for example, a smart phone or a smart watch, or they can be of different types of electronic devices. For example, the first electronic device is a smart phone and the second electronic device is a smart watch, or the first electronic device is a smart watch and the second electronic device is a smart phone. Here, the embodiments of the present application do not make specific limitations in this regard.

[0053] S202: When the first electronic device establishes a connection with the third electronic device through a data cable and receives a key operation on a preset physical key of the first electronic device, the first electronic device responds to the call request and establishes a call connection with the second electronic device;

[0054] Through S201 above, the first electronic device receives a call request. Here, it should be noted that the screen of the first electronic device may or may not display the call request. Here, the embodiments of the present application do not make specific limitations in this regard.

[0055] Since only the screen of the first electronic device is damaged and the call function is normal, here, the first electronic device can receive the call request and use the form set by the first electronic device to prompt the user that the call request has been received. For example, it can be a ringtone, it can also be a vibration, or it can be a combination of a ringtone and a vibration.

[0056] Then, after the first electronic device receives the call request, when the first electronic device establishes a connection with the third electronic device through a data cable and simultaneously receives a key operation on a preset physical key of the first electronic device, at this time, the response to the call request is triggered, and the first electronic device establishes a call connection with the second electronic device. Among them, the preset physical key of the first electronic device here can be a volume key, it can also be a power on / off key, or other physical keys, or a combination of physical keys. Here, the embodiments of the present application do not make specific limitations in this regard.

[0057] In addition, the above key operation can be a long press operation, or a click operation, it can be a single click operation, or a double click operation. Here, the embodiments of the present application do not make specific limitations in this regard.

[0058] In this way, a call connection can be established between the first electronic device and the second electronic device.

[0059] S203: The second electronic device receives and responds to a touch operation on the dial of the second electronic device to generate a password;

[0060] Establish a call connection between the first electronic device and the second electronic device. At this time, the first electronic device is connected to the third electronic device through a data cable. On this basis, the user performs a touch operation on the dial pad of the second electronic device, so that the second electronic device receives the touch operation on the dial pad of the second electronic device. In response to the touch operation, a password is generated.

[0061] The password here needs to be compared with the unlock password of the first electronic device. Therefore, the user needs to perform touch operations according to the rules to obtain the password. Among them, the first electronic device may be set with a password or may not be set with a password. If no password is set, the password of the first electronic device is empty. If a password is set, the password of the first electronic device is not empty. If it is not empty, the password can also be divided into a pure number password, a nine-grid pattern password, a password composed of numbers and letters. Of course, it can also be other types of passwords. Here, the embodiments of the present application do not make specific limitations on this.

[0062] S204: The second electronic device sends the password to the first electronic device based on the call connection;

[0063] After generating the password, the second electronic device needs to send the password to the first electronic device. Here, in order to send the password to the first electronic device, the second electronic device can send the password to the first electronic device based on the call connection, so that the first electronic device receives the password.

[0064] S205: The first electronic device verifies the password to obtain a verification result;

[0065] S206: When the verification result indicates successful verification, the first electronic device unlocks the first electronic device.

[0066] After receiving the password, the first electronic device needs to verify the password. Here, the password is mainly compared with the unlock password stored locally in the first electronic device to check whether they are consistent. When they are consistent, it can be determined that the verification result indicates successful verification. At this time, the first electronic device unlocks the first electronic device, so that the first electronic device is successfully unlocked.

[0067] In order to establish a call connection between the first electronic device and the second electronic device, in an alternative embodiment, S202 may include:

[0068] When a connection is established with the third electronic device through a data cable and key operations on the volume up key and volume down key of the first electronic device are received, the first electronic device responds to the call request and establishes a call connection with the second electronic device.

[0069] Understandably, the first electronic device establishes a connection with the third electronic device through a data cable. At the same time, the first electronic device receives key operations on its volume up key and volume down key. That is to say, the user connects the first electronic device to the third electronic device using the data cable and presses the volume up key and volume down key simultaneously. In this way, the first electronic device is triggered to respond to the call request, and a call connection is established between the first electronic device and the second electronic device.

[0070] In this way, through the connection with the third electronic device and the received key operations on the volume keys, the first electronic device establishes a call connection with the second electronic device, so that the second electronic device can send a password to the first electronic device, thereby achieving unlocking.

[0071] In addition, in order to establish a call connection between the first electronic device and the second electronic device, in an alternative embodiment, S202 may include:

[0072] When a connection is established with the third electronic device through a data cable and a long press operation on the power on / off key of the first electronic device is received, the first electronic device responds to the call request and establishes a call connection with the second electronic device.

[0073] Understandably, the first electronic device establishes a connection with the third electronic device through a data cable. At the same time, the first electronic device receives a long press operation on its power on / off key. That is to say, the user connects the first electronic device to the third electronic device using the data cable and the user long presses the power on / off key. In this way, the first electronic device is triggered to respond to the call request, and a call connection is established between the first electronic device and the second electronic device.

[0074] In this way, through the connection with the third electronic device and the received long press operation on the power on / off key, the first electronic device establishes a call connection with the second electronic device, so that the second electronic device can send a password to the first electronic device, thereby achieving unlocking.

[0075] It should be noted that the key operations on the preset physical keys are not limited to the above-listed methods and may also be other methods. Here, the embodiments of the present application do not make specific limitations in this regard.

[0076] Among them, after the second electronic device generates the password, it needs to send the password to the first electronic device. In an alternative embodiment, S204 may include:

[0077] The second electronic device sends the password to the first electronic device based on the call connection using Dual Tone Multi Frequency (DTMF).

[0078] Understandably, after establishing a call connection between the first electronic device and the second electronic device, the second electronic device can send the password to the first electronic device based on this call connection using the DTMF transmission method, so that the first electronic device receives the password for unlocking through verification.

[0079] In this way, based on the call connection and using the DTMF transmission method, the password is sent to the first electronic device, which helps to unlock through password verification.

[0080] In an optional embodiment, in order for the first electronic device to verify the password, S205 may include:

[0081] When the password is empty, the first electronic device obtains a verification result according to the setting of the unlocking password of the first electronic device;

[0082] When the password is not empty, the first electronic device determines the type of the password according to the format of the password;

[0083] The first electronic device translates the password according to the translation method corresponding to the type to obtain the translated password;

[0084] When the translated password is consistent with the unlocking password of the first electronic device, the verification result obtained by the first electronic device indicates successful verification;

[0085] When the translated password is inconsistent with the unlocking password of the first electronic device, the verification result obtained by the first electronic device indicates failed verification.

[0086] Understandably, first judge the password to see if it is an empty password. If so, it is necessary to check whether the first electronic device has set an unlocking password. Then, determine the verification result based on whether the first electronic device has set an unlocking password.

[0087] If not, at this time, the first electronic device needs to first determine the type of the password according to the format of the password, and then translate it according to the translation method corresponding to the type to obtain the translated password, and then compare the translated password with the unlocking password of the first electronic device to determine the verification result.

[0088] In this way, first determine whether the password is empty, and determine the verification result according to whether the password is empty, so that the verification result can be obtained, and then unlock when the verification is successful.

[0089] In an optional embodiment, in order to determine whether the password is empty, the above method may further include:

[0090] When the password is the first preset character, the first electronic device determines that the password is empty;

[0091] When the password is not the first preset character, the first electronic device determines that the password is not empty.

[0092] Understandably, after receiving the password, the first electronic device parses the password. Specifically, it first compares the characters in the password with the first preset character. If the password is the first preset character, then the first electronic device determines that the password is an empty password. If the password is not the first preset character, it means that the password is not an empty password.

[0093] In this way, the first electronic device directly compares the password with the first preset character to determine whether the password is empty, and then determines how to obtain the verification result based on whether the password is empty, which helps to achieve unlocking.

[0094] For the case where the password is empty, in an alternative embodiment, when the password is empty, according to the setting of the unlocking password of the first electronic device, obtaining the verification result may include:

[0095] When the password is empty and the first electronic device is not set with an unlocking password, it is determined that the verification result indicates successful verification;

[0096] When the password is empty and the first electronic device is set with an unlocking password, it is determined that the verification result indicates failed verification.

[0097] Understandably, when the password is empty, by checking the setting information of the first electronic device and finding that the first electronic device is not set with an unlocking password, it is determined at this time that the verification result indicates successful verification. When the password is empty, by checking the setting information of the first electronic device and finding that the first electronic device is set with an unlocking password, it is determined at this time that the verification result indicates failed verification.

[0098] In this way, further checking the setting information of the unlocking password of the first electronic device when it is known that the password is empty, and then determining the verification result, helps to achieve unlocking.

[0099] For the case where the password is not empty, in an alternative embodiment, when the password is not empty, the first electronic device determines the type of the password according to the format of the password, which may include:

[0100] When the password is not empty and the first N preset characters of the password are the second preset character, the first electronic device determines that the password is a numeric password;

[0101] When the password is not empty and the first N preset characters of the password are the third preset character, the first electronic device determines that the password is a nine - grid pattern password;

[0102] When the password is not empty and the first N preset characters of the password are the fourth preset character, the first electronic device determines that the password is a combination of numbers and letters.

[0103] Understandably, when the password is not empty, the first N characters of the preset password are viewed. Here, N can be selected as 5. The preset first N characters are used to determine the type of the password. When the preset first N characters are the second preset characters, the first electronic device determines that the password is a pure-numeric password. When the preset first N characters are the third preset characters, the first electronic device determines that the password is a nine-grid pattern password. When the preset first N characters are the third preset characters, the first electronic device determines that the password is a combination of numbers and letters.

[0104] For example, when the preset first N characters are ##1**, the first electronic device determines that the password is a pure-numeric password. When the preset first N characters are ##2**, the first electronic device determines that the password is a nine-grid pattern password. When the preset first N characters are ##3**, the first electronic device determines that the password is a combination of numbers and letters.

[0105] In this way, the type of the password can be determined, and thus the corresponding translation method can be used to process the password according to the type of the password to obtain the translated password to determine the verification result, which is beneficial to unlocking.

[0106] For different types of passwords, the translation methods are different. In an optional embodiment, the first electronic device translates the password according to the translation method corresponding to the type to obtain the translated password, which may include:

[0107] When the password is a pure-numeric password, the first electronic device determines the numbers at the preset positions in the password as the translated password.

[0108] When the password is a nine-grid pattern password, the first electronic device determines the pattern formed by connecting the numbers at the preset positions in the password on the nine-grid as the translated password.

[0109] When the password is a combination of numbers and letters, the first electronic device translates the numbers at the preset positions in the password in decimal or octal according to the American Standard Code for Information Interchange (ASCII) encoding to obtain the translated password.

[0110] Understandably, for a password consisting of pure numbers, the password includes characters representing the type, characters of the password content, and may also include ending characters. Then, when translating the password to obtain the translated password, the first electronic device only needs to use the numbers at the preset positions as the translated password; for a password in the form of a nine - grid pattern, the password includes characters representing the type, characters of the password content, and may also include ending characters. Then, when translating the password to obtain the translated password, the first electronic device only needs to use the pattern formed by connecting the numbers at the preset positions on the nine - grid as the translated password; for a password combining numbers and letters, the password includes characters representing the type, characters of the password content, and may also include ending characters. Then, when translating the password to obtain the translated password, the first electronic device only needs to translate the numbers at the preset positions of the password in the decimal or octal manner in the ASCII code. Here, when the touch operation on the dial pad uses the decimal in the ASCII code, the numbers at the preset positions are translated in the decimal of the ASCII code, and when the touch operation on the dial pad uses the octal in the ASCII code, the numbers at the preset positions are translated in the octal of the ASCII code.

[0111] In this way, the translation methods for different types of passwords are different, thus realizing the translation of different types of passwords, enabling the first electronic device to obtain the verification result using the translated password, and thus realizing unlocking.

[0112] In an optional embodiment, in order to export important data in the first electronic device, the above - mentioned method may further include:

[0113] When the verification result indicates successful verification, the first electronic device authorizes USB debugging for the third electronic device.

[0114] Understandably, if after verification, when the verification result indicates successful verification, in addition to completing unlocking, the first electronic device also authorizes USB debugging for the third electronic device, enabling the third electronic device to access the data in the first electronic device, such as multimedia data, text messages, address books, application data, etc.

[0115] In this way, the third electronic device can export the data of the first electronic device through a data cable, avoiding the inconvenience caused by some data being unable to be exported and solving the problem of inaccessibility due to screen damage.

[0116] For the case where the verification result indicates successful verification, in an optional embodiment, the above - mentioned method may further include:

[0117] When the verification result indicates successful verification, the first electronic device sets the automatic screen-off duration of the first electronic device to a preset duration.

[0118] Understandably, if the verification result obtained through verification is successful verification, in addition to unlocking, the first electronic device also sets its own automatic screen-off duration to a preset duration. In this way, it can be ensured that the screen is turned off within the preset duration.

[0119] In this way, the first electronic device can achieve automatic screen-off after unlocking, and the automatic screen-off duration is the preset duration. By flexibly setting the preset duration, it can be set according to its own actual needs, ensuring the security of the first electronic device.

[0120] For the case where the verification result indicates verification failure, in an optional embodiment, the above method may further include:

[0121] When the verification result indicates verification failure, the first electronic device disconnects the call connection with the second electronic device.

[0122] Understandably, when the verification result obtained through verification indicates verification failure, the password entered by the user in the second electronic device is incorrect. Then, considering the data security of the first electronic device at this time, the first electronic device disconnects the call connection with the second electronic device, that is, the first electronic device hangs up the phone, thereby disconnecting the call connection between the first electronic device and the second electronic device.

[0123] In this way, by disconnecting the call connection when the verification fails, the security of the first electronic device can be ensured, preventing the threat to data security caused by multiple password attempts.

[0124] In order to prompt the user for the next operation to achieve unlocking, in an optional embodiment, the above method may further include:

[0125] When the first electronic device establishes a call connection with the second electronic device, the first electronic device emits a first prompt tone.

[0126] Understandably, when the first electronic device establishes a call connection with the second electronic device, at this time, the user needs to be reminded that the call connection has been established. The first electronic device can use the method of emitting a first prompt tone. Among them, the first prompt tone is used to prompt that the first electronic device and the second electronic device have established a call connection; that is to say, the first electronic device makes the user aware that the two have established a call connection through emitting a prompt tone, and the user can perform the next operation of entering the password.

[0127] In this way, it helps the user to know that a call connection has been established between the first electronic device and the second electronic device, and then the user can perform the next operation, which helps to improve the unlocking efficiency.

[0128] Considering the security of the entire unlocking process, in an optional embodiment, the above method may further include:

[0129] When the connection between the first electronic device and the third electronic device through the data cable is disconnected, the first electronic device disconnects the call connection with the second electronic device and emits a second prompt tone.

[0130] It can be understood that during the entire unlocking process, when the first electronic device is connected to the third electronic device through the data cable, this connection needs to be maintained all the time to achieve unlocking. If the connection between the first electronic device and the third electronic device through the data cable is disconnected, at this time, to ensure data security, the first electronic device disconnects the call connection with the second electronic device and emits a second prompt tone. Among them, the second prompt tone is used to prompt that the connection between the first electronic device and the second electronic device through the data cable with the third electronic device is disconnected; that is to say, once the connection between the first electronic device and the third electronic device is disconnected, the call connection is also disconnected, and a prompt tone for disconnecting the connection between the first electronic device and the third electronic device is emitted, so that the user knows that the unlocking is terminated at this time.

[0131] In this way, when the connection between the first electronic device and the third electronic device through the data cable is disconnected, the second prompt tone is emitted, so that the user knows that this no longer meets the unlocking conditions. In this way, the user is promptly prompted that the unlocking is terminated, which ensures the data security in the first electronic device and improves the security of unlocking.

[0132] The following is an example to illustrate the unlocking method described in one or more of the above embodiments.

[0133] In this example, the Subscriber Identity Module (SIM) card call is used as the channel for remote operation, and DTMF is used as the method for transmitting the mobile phone password, so as to remotely unlock the mobile phone, and at the same time turn on USB debugging and perform USB debugging authorization. Among them, the entire process mainly includes the following parts:

[0134] 1. Establish a remote channel

[0135] To establish a remote channel, two mobile phones inserted with SIM cards are required, that is, in addition to the mobile phone to be controlled (hereinafter referred to as the controlled machine, and the screen of this controlled machine is damaged), a mobile phone for control (hereinafter referred to as the control machine) is also required.

[0136] First, use the controlling device to call the controlled device. After the paging is established, the controlled device answers the call in the following way: Prepare a USB data cable with one end already connected to the computer, press the volume up and down keys simultaneously, and insert the other end of the USB data cable into the controlled device. This operation mode will trigger the controlled device to answer the call, indicating that the remote channel between the controlled device and the controlling device is established.

[0137] After the remote channel is successfully established, the controlled device will emit a prompt tone in the voice link (equivalent to the above first prompt tone), indicating that the remote channel between the two parties has been opened.

[0138] If the USB data cable is disconnected during the call (regardless of whether it is the mobile phone end or the computer end), it means that the remote channel is disconnected and cannot be re-established during this call. The controlled device will also emit a prompt tone in the voice link (equivalent to the above second prompt tone).

[0139] Figure 3 It is a schematic flowchart of the first example of an unlocking method provided by an embodiment of the present application. As Figure 3 shown, the controlling device 31 includes a communication module 311 and a communication module 312, and the controlled device 32 includes a communication module 321, an application module 322, and a system module 323. Among them, the process of establishing a remote channel is as follows:

[0140] S301: The application module 311 sends an instruction to call a phone to the communication module 312;

[0141] S302: The communication module 312 sends a call request to the communication module 321;

[0142] S303: The communication module 321 notifies the application module 322 of an incoming call;

[0143] S304: The application module 322 receives the information that the volume up and down keys have been pressed and the information that the USB is inserted through the system module 323, and triggers the execution of S305;

[0144] S305: The application module 322 sends an instruction to answer the call and establish a channel to the communication module 321, so that the controlled device 32 establishes a call connection with the controller 31.

[0145] 2. Enter the mobile phone password

[0146] After the remote channel between the controlled device and the controlling device is established, the user can operate to enter the password on the dial pad of the controlling device.

[0147] Among them, the following three password methods can be supported in this example:

[0148] 1) Password consisting of pure numbers

[0149] The format starts with ##1**,** and ends with ##, and the password content is filled in the middle according to its original content.

[0150] Taking the password 123456 as an example, the remotely input content is ##1**123456**##.

[0151] 2) Password of nine - grid pattern

[0152] The format starts with ##2**,** and ends with ##, and the password content is mapped to numbers according to the following Figure 4a and Figure 4b and filled in the middle.

[0153] Figure 4a Figure shows an optional schematic diagram of the password of the nine - grid pattern provided by the embodiment of the present application. Figure 1 As Figure 4a shown, taking the pattern password above Figure 4a as an example, and comparing with the Figure 4b numbers, the remotely input content is ##2**12569**##.

[0154] 3) Password of combination of numbers and letters

[0155] The format starts with ##3**,** and ends with ##, and the numbers and letters are filled in the middle according to # plus the decimal digits of the ASCII code. Taking the password content abc123XYZ as an example, the remotely input content can be ##3**#97#98#99#49#50#51#88#89#90**##.

[0156] In addition, it should be noted that if the controlled machine does not set a password, then the remotely input content is ##0****##.

[0157] Figure 5 Figure shows a schematic flow diagram of the second example of an optional unlocking method provided by the embodiment of the present application. As Figure 5 shown, based on the Figure 3 structure, the process of inputting the mobile phone password is as follows:

[0158] S501: The application module 311 sends the dial - pad input password to the communication module 312;

[0159] S502: The communication module 312 uses the DTMK transmission method to send the password to the communication module 321;

[0160] S503: The communication module 321 reports the DTMF event to the application module 322;

[0161] S504: The application module 322 sends the password verification result to the system module 323.

[0162] 3. Verify the password and generate a response action

[0163] The password entered by the control machine on the dial pad is received by the controlled machine in the form of DTMF.

[0164] Only when the remote channel is open will the controlled machine verify the password.

[0165] The password is first recognized from the DTMF, extracted and translated one by one. After obtaining the complete password, it will be verified with the password set by the user in the system. (If there is no password, it is directly regarded as successful verification)

[0166] After the password verification is successful, if the mobile phone is in the unlocked state, the mobile phone will be unlocked; in addition, the automatic screen-off time is set to 10 minutes; at the same time, the USB debugging mode is enabled, and the computer currently connected by USB is automatically authorized for USB debugging.

[0167] If the password verification fails, the current call will be immediately hung up.

[0168] Figure 6 It is a schematic flow diagram of the third example of an optional unlocking method provided by the embodiment of the present application. As Figure 6 shown, based on the above Figure 3 structure, the process of password verification failure is as follows:

[0169] S601: The system module 323 sends the information of password verification failure to the application module 322;

[0170] S602: The application module 322 sends the instruction to hang up the phone to the communication module 321;

[0171] S603: The communication module 321 sends the information of disconnecting the call to the communication module 312;

[0172] S604: The communication module 312 reports the disconnected information to the application module 311.

[0173] It should be noted that the method of establishing a channel (the controlled machine answers the phone) in this example is only an example and can be replaced by other methods that do not use screen input to answer. The advantage of the current method (press the volume up and down keys and insert the USB data cable) is that it can prevent the computer at the other end of the USB connection from being replaced after the channel is established.

[0174] The feature code transmitted by DTMF in this example (##X** is opened and ends with **##), and the mapping relationship between different types of passwords and DTMF are only examples and do not represent the only implementation method.

[0175] It can be seen that in the case where the device screen cannot be used, this embodiment provides a method that is generally applicable to the vast majority of mobile phones to open the USB debugging channel, thereby providing a channel to replace touch input and display output, enabling data backup and other repair operations; using a voice link with relatively high security to transmit the device password can effectively protect the user's privacy.

[0176] This embodiment provides a method for remotely unlocking a mobile phone and opening the USB debugging of the mobile phone (while performing USB debugging authorization). This method provides a possibility that in the case where the mobile phone screen is damaged, it is possible to use an external computer and related tools of the Android Debug Bridge (adb) to replace the touch input and display output of the mobile phone; and then realize the operation of the mobile phone and the backup of data.

[0177] An embodiment of the present application provides an unlocking method, which is applied to a first electronic device that cannot respond to a touch operation on the screen. The method includes: after receiving a call request from a second electronic device, when a connection is established with a third electronic device through a data cable and a key operation on a preset physical key of the first electronic device is received, responding to the call request, establishing a call connection with the second electronic device, receiving a password sent from the second electronic device based on the call connection, verifying the password to obtain a verification result, and unlocking the first electronic device when the verification result indicates successful verification; that is to say, in the embodiment of the present application, a call request is sent from the second electronic device to the first electronic device, so that a call connection is established when a connection is established with the third electronic device through a data cable and a key operation on a preset physical key is received. On this basis, the password received from the second electronic device is verified, and the first electronic device is unlocked when the verification is successful. In this way, any electronic device other than the first electronic device can establish a call connection with another electronic device by receiving a key operation on a preset physical key when the first electronic device is connected to the third electronic device, and then unlock the first electronic device through password verification, expanding the scope of application of unlocking and thus improving the unlocking efficiency.
