So...just to be sure. There is no way to sync & or backup any information on my G4 via my Mac with AirDroid...correct...? I mean, I do use Kies...however it is rather confusing via Mac. I constantly get multiple contacts added to device when I backup. Any help...?
Contacts and SMS Backup and Restore
There are such apps like Helium or SMS Backup and Restore. You can search and download them on play store.
