How to restore factory settings on a mobile phone
Many smartphones will experience abnormal freezes due to the accumulation of junk files after being used for a period of time, making them very uncomfortable to use. So what should you do? You can restore your phone to factory settings, just like reinstalling the computer system. The system has become very clean and is much better to use than before.
1. Press the menu key on the home interface to enter the settings menu. It can also be accessed from the settings icon.
2. Drag the interface to find "Backup and Reset". Some phones may be private.
3. After entering, you can see the option to restore factory settings. You can check Google to back up some useful data, depending on your personal needs. However, many CN (mainland China). There is no gmail on the phone, so there is no backup.
4. After clicking Restore factory settings, enter the next option.
There is an option to format the SD card, but I don’t recommend checking it. After checking, all contents in the card will be cleared.
5. Finally, click to clear all content. Of course, it is to clear the contents of the phone itself.
After selecting, the phone will be turned off and then restarted. The restart may be slightly slower than usual because the data on the phone is being cleared.
Note Matters:
1. Clear all software installed after factory settings
2. Restoring to factory settings is equivalent to re-flashing the computer system, and the speed is equivalent to that of a new mobile phone. /p>
3. It is best not to format the SD card. The data may not be recovered after formatting.
