How to back up and empty mobile phone data

We need to back up our own information, especially important information such as contacts and text messages. The method is simple, just click Settings-Account-to start data synchronization.

Storage disk situation

Then return to the settings page, click "About Mobile Phone" and select "Save". Here we can see the storage of memory cards, as well as clearing system data and formatting storage disks.

Clear system data

Click "Clear System Data", and then make sure that all data on your system will be cleared, including your flyme account, but the pictures, videos and other things stored on the storage disk are still there.

Format storage disk

Therefore, we need to format the storage disk. This action will clear all the software, games, pictures and videos in your mobile phone, including titanium backup data, and restore it to its original storage size. So when formatting, you should make sure what information you need.
