Mobile phone abnormal restart, crash and data lost for no reason after booting
Reason:
When the mobile phone is in normal use, it suddenly restarts, freezes, and the screen goes black. If the data stored in the mobile phone is lost after starting it, check it according to the following steps:
1. Verify the phone model, system version and previous operations.
2. There will be no unreasonable data loss on the phone normally, and to confirm whether third-party security software has been downloaded or system is flashed before.
3. To confirm whether cloud services or other synchronization software for data synchronization has been used before, and try to restore data; If there is no synchronization data before, the data can not be retrieved locally.
4. It is suggested to go to after-sales outlets so as to check if it is due to the local mobile phone system, and observe and use for a period of time to see if it is normal.
5. It is suggested to go to after-sales center for inspection, and the engineer's inspection result shall prevail.
