Hard Reset - advantages and disadvantages Alcatel TCL S820?

In simple words, Hard Reset means hard resetting the phone. As a result, the system automatically returns to the factory settings and the system is completely cleared. Contacts, correspondence, application, files, search queries, passwords - all of this is deleted from the device's memory.

Benefits of Hard Reset:
The ability to reset the phone to factory settings.
Removing viruses that have entered your phone.
Solving problems that have arisen on the device between applications and for example bluetooth.

Disadvantages of Hard Reset:

Unfortunately, in some cases, not all viruses on Android will be removed, even after a hard reset.


What needs to be done before the Hard Reset operation.
If you want to do a hard reset on your phone, then make sure you know the login / password for your google account.
You can sign out of your google account before resetting. In this case, after performing a factory reset, the phone will not ask for any logins and passwords and you can use your device.
In case you have already done a factory reset and cannot remember the login and password for logging into your Google account, for most models there are instructions for bypassing protection (FRP).
Owners of modern phone models will need to contact the official service center to bypass the protection of the FRP.

After performing a hard reset, your device will be completely wiped clean. Everything that was in the memory of your device will be deleted.

What can be done to avoid losing important information?
