Restoring Android’s lost data is very simple. You just need a Android data recovery tool.
You can also refer to other methods, but we’d better recommend Android data recovery tools because it’s more secure.
Method 1: how to restore data to backup after losing data
Nowadays, people usually use the system backup function or cloud services (such as Google) to backup their mobile phone data. If you have a good habit of doing regular backup or synchronization, it’s easier to recover files after you reset the Android phone or lose data when you leave the factory.
Option 1: Recover Android Data from Google
If you have set up Google account on your Android and enabled synchronization for all data, after factory reset, you can set up your Google account again on the phone. An option during the set up process will allow you to restore all the synced data.
Option 2: Restore Android Data from Backup
Many Android phones are endowed with local backup app or function. If you have backed up data regularly, then, after factory reset, just go to “Settings” > “Back up & restore”, and select the latest backup file to restore data from backup.
