Read below for some important tips on how to backup Android data in a easy process:
Samsung user can also backup data by using Official Sumsang Kies. If you backup data manually, you will get more options for what to choose from. You can also move your data to other Android devices from different manufacturers, i.e moving Samsung Galaxy S5 backup data to Google Nexus 10. If you already have a custom recovery (ClockworkMod, TWRP etc.) installed on your phone, we strongly recommend a backup using that as it creates a complete image of your existing phone set up.

Few more important things that you must remember before installing any custom ROMs or Official Firmwares:

  • You might face some problems in connecting your Android device to the computer. How to fix? -> You need to enable USB debugging mode. See here: How to Enable USB Debugging — for Gingerbread, Ice Cream Sandwich and KitKat.
