This information is applicable to all the realme devices.
If your phone crashes, please try to solve the problem as follows:
1. In the case that the phone is stuck and there is no response, you can try to press and hold the power button and the volume up button at the same time to force the device to restart.
2. If it is a third-party application that causes a crash, it may be an application compatibility issue. It is recommended that you download it from the official software store, or you uninstall the third-party application that caused the system to be abnormal, and wait for the application update to be repaired before installing it.
3. If you use the built-in function to crash, it is recommended that you back up the important data and then try to restore the factory settings.
4. If you have an external memory card, please try to freeze it after you try to pull it out. If you pull it out, it will not crash. It may be that the microSD card is incompatible or damaged, resulting in abnormal data reading and writing. It is recommended that you change the card in time.
If the above steps do not solve your problem, please go to the nearby autorized realme service center for testing.
