Unfortunately I dropped my phone (galaxy S3) and the screen is black, so I cannot do anything on the phone. But other than that, it is fully functioning, and I can see the files when connected to a pc.
There is this question which states that the phone needs to be rooted in order to access the database where the contacts are stored. Is there an other way to retrieve contacts when the phone is not rooted?
The gmail sync was unfortunately not enabled. Is it possible to turn this on remotely?
