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.
Maybe you will ask anxiously: “Could it be possible that I can get my important files back after upgrading??” Then take it easy and follow the instructions below to regain your documents!

Now that you’ve known flashing/rooting could be a risky activity, so backing up your important data is the most significant step you should take before doing upgrade. Then how to do that? The most recommendable way would be using wireless Google synchronous service. The specific steps are as follows:
Step 1. Enter “Settings ” of your Android device and tap on “Accounts”.
Step 2. Choose your Google account.
Step 3. Preview and backup the data that you need to Google Drive.
Note: Google backup services do have some limitations: Firstly, it can only backup the applications whose developers have enabled the capability; Secondly, 15GB,a very small volume of memory, is provided freely by Google Drive, which means that it would charge you after backing up more than 15GB.
It is certainly unworthy enjoying advantages brought by Android Update at the cost of losing important data, so you should highly have forethought to backup what is indispensable for you before something bad really happen.
