Why Backup Contacts?
When new contact data is created on your Android™ device, you would think that it’s all saved at the same place by default? this is not always true.
Contacts Data could be saved in places like:
⇨ Google account – contact data
⇨ Phone/Tablet – contact data
⇨ Other: Facebook etc. – contact data
The Backup Contacts application retrieves ALL contact data stored on your Android™ device and saves it into ONE text file for safe keeping.
