Techopedia explains Android Recovery
Android recovery is generally done using Android recovery mode, which is a native device recovery provided by Android. By using a combination of keys, recovery mode is displayed on the Android device. The user can select any of the available options to restore or edit the device.
After-market Android recovery solutions provide the ability to create a backup of an Android device and data on external storage. This backup can be restored later by transferring data to the phone using a USB cable.
Android recovery might also be performed by simply removing faulty and buggy apps or viruses from the device.
