Common troubleshooting of mobile phones:

Fault phenomenon: the phone flashes back or crashes when running the APP.

Sometimes, clicking an APP will flash back. At this time, consider whether the APP is normal, safe and non-toxic. You can delete the app and try downloading it again. Then, considering that the remaining memory space of the mobile phone is too small, the mobile phone should be cleaned at this time.

The crash occurred during the running of the APP, which may be due to the following reasons.

1, the mobile phone runs out of memory. It is recommended to close some programs running in the background.

2. The mobile phone is ROOT. OTA upgrade or after-sales software upgrade is recommended.
