If, for any reason whatsoever, you want to keep the data (apps, photos, conversations..) within your Android, and then restore them on another device, then we recommend that you use the Backup feature of Google.
In this tutorial, we will explain step by step how to preserve your data. and the restore.
Note that the name of the options may differ from one device to another, here we have used a Sony Xperia.
To find these functions on your device, you can perform a search, or you visit the website of the manufacturer.
Back up apps and data on Android.
The easiest way to save the data and applications from your tablet or smartphone Android is to use the native functionality Backup.
Google specifies that as long as you use Google Drive as a backup application then the following items will be retained :
Google calendar : settings and events.
Wi-Fi networks and passwords.
Display settings (brightness and sleep).
Settings-language and input.
Date and time.
Parameters and data for the apps not created by Google (varies depending on the app).
To start the process, make sure that you are logged in to your Google account. Then, go to Settings → System → Backup. Finally, appears the option to Save to Google Drive, click to select it.
We also recommend that you enable auto-Backup (Settings → System → Backup and restore).
The process will take a few minutes, depending on the amount of data to save.
Restore the backup Android.
Restoring a backup is mostly automatic, since in effect, when you add a new Android to your Google account, you are asked to choose the backup to restore.
To do it manually, go to Settings → System → Backup and Restore → Restore data, and then confirm.
Note that for some apps, it is not possible to restore all of their settings and data.
