Problems solved by technology
As the surface device of the mobile terminal, the back cover is prone to drop and collision during use, which will cause damage to the NFC antenna. Therefore, the back cover needs to be replaced to use the NFC function normally.
Since the back cover of each mobile terminal may be the same, but its NFC antenna is different, when the back cover of the mobile terminal is replaced, it is easy to cause the NFC function to be abnormal.

Embodiment Construction
[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.
[0025] It should be noted that the NFC antenna is generally arranged on the rear cover of the mobile terminal due to its large area, so that the sensing distance of the NFC antenna can be effectively maintained. As the surface device of the mobile terminal, the back cover is prone to drop and collision during use, which will cause damage to the NFC antenna. Therefore, the back cover needs to be replaced to use the NFC function normally. Since the back covers of various mobile te...

The embodiment of the present application discloses a NFC function detection method, device, storage medium, and mobile terminal; wherein, the NFC function detection method includes: acquiring the first detection point set on the NFC antenna and the first detection point set on the main board of the mobile terminal The distance between the second detection points; determine whether the distance is less than a preset threshold value; if the distance is less than or equal to the preset threshold value, then determine that the NFC function of the mobile terminal is in a normal state; if If the distance is greater than the preset threshold value, it is determined that the NFC function of the mobile terminal is in an abnormal state. This solution can accurately determine whether the NFC antenna in the back cover of the mobile terminal matches the mobile terminal after the back cover of the mobile terminal is replaced, so as to avoid the problem of abnormal NFC function.
Description
technical field [0001] The present application relates to the field of communication technologies, and in particular to an NFC function detection method and device, a storage medium and a mobile terminal. Background technique [0002] With the rapid development of communication technology, more and more mobile terminals use Near Field Communication (NFC, Near Field Communication) technology. [0003] One of the key points of the NFC technology lies in its antenna. Due to its large area, the NFC antenna is generally installed in the back cover of the mobile terminal, so that the sensing distance of the NFC antenna can be effectively maintained. As the surface device of the mobile terminal, the back cover is prone to drop and collision during use, which will cause damage to the NFC antenna. Therefore, the back cover needs to be replaced to use the NFC function normally. Since the back covers of various mobile terminals may be the same, but their NFC antennas are different, wh...
