This information is applicable to all the realme devices.
If your phone has an automatic shutdown/restart, please try to solve the problem as follows:
1. If the daily use of the mobile phone is normal, there will be a restart when opening a specific program. It may be an application compatibility issue. It is recommended that you download the official software store or uninstall the application. After the application update is fixed, installation.
2. If you have an external memory card, please try to remove it and confirm whether this problem will occur. The memory card may be incompatible or damaged, resulting in abnormal data reading and writing. It is recommended that you change the card in time.
3. If there is an automatic restart, there is an automatic switch on and off. It is recommended that you restore the factory settings after backing up the data (Settings - Other Settings - Restore Phone - Clear all data).
If the above steps do not solve your problem, please go to the nearby realme service center for testing.
