Steps to Recover Lost Files After Android Update

Types of Android update and its bad effect.

Basically, Android update includes two common types:
1.The official Android update (Android 7), which only adds several new functions or fix some system bugs, will not cause any data loss.
2.The second one is installing a ROM. Plights are either result from forgetting to wipe data/factory reset and wipe cache partition or having installed an unmatched ROM.


Even though a large number of Android users would take update as a practical way to personalize their phones and they can do much more operations after updating. However, every coin has two sides. Android update might bring about considerable losses of data, including all contacts, messages, photos, videos, music, documents apps and so on.


In most cases, one becomes aware of this unpleasant consequence just after the upgrade is finished or even unfinished. Now please move to next section to see how to recover data afterwards.

Step 3. Preview and backup the data that you need to Google Drive.
