What should I do if Mo Fan China Mobile m8 12 phone crashes?

1. If the phone is stuck, I suggest you press and hold the Home button for about 2 ~ 3 seconds, and the Task Manager option will appear. Click to enter Task Manager-then click Active Application Options at the top of the screen-and click End Options. Clear the memory (enter the task manager-click the "RAM" option at the top of the screen-click the "Clear Memory" option).

2. Turn off the phone and restart it.

3. Check whether there is any incompatibility problem caused by downloading third-party software for setting.

4. If the problem still exists, it is recommended that you back up data (such as contacts, text messages and photos) and restore factory settings (Settings-Reset-Restore factory settings). It is recommended not to check "Format USB Memory" when restoring the factory settings, as all data in the USB memory of the mobile phone will be lost after checking.

5. If the problem still exists after the above operation, please bring your mobile phone, purchase invoice and maintenance card to Samsung Service Center for professional inspection.
