Problems solved by technology

When many users encounter typing on WeChat and other interactive software (Chinese Jiugongge, 26 grid, etc.), the user is used to typing with the thumb, and the other four fingers and the palm hold the phone. When the thumb finishes typing the last word, the thumb distance click function The keys or the preview frame are far away, causing the thumb to be out of reach, causing false touches and bad user experience.
