Wechat is running, but pressing the back button can't return to the desktop, and it will switch back and forth infinitely in programs such as SMS and call records. For example, press in the WeChat interface. If the phone buttons are out of order, we suggest you: 1. If you can't use the Back button to return to the previous interface or exit when running a program, we suggest that you click the HOME button to return to the standby interface and try to re-enter the program.

2. Turn off the phone and restart it.

3. If the back button, menu button, recent application button and HOME button of the mobile phone can't be used, it is recommended to uninstall the recently installed software and delete it as much as possible.

4. If not, please back up the data (contacts, pictures, etc. ) and restore it to the factory settings.

If the problem persists, there may be something wrong with the internal hardware. I suggest you take the three-guarantee certificate of your mobile phone and send it to the nearest service center for engineers to check the machine.
