Sometimes the phone crashes, and the WeChat message arrives, but it can't be seen. What should I do?

This situation is mostly caused by the conflict of driver software, but the motherboard problem is also ruled out;

The following investigations are recommended:

1, system upgrade, software upgrade, will it crash?

2. If it is still the same, clean up the garbage in the mobile phone system and kill virus. If it is still the same, restore the factory settings of the mobile phone.

3, if still, brush the machine again.

4, if still, most of them are motherboard problems.
