Recently AT&T has started forcing our Samsung GS3's to upgrade to Android version 4.3. When the devices upgrade, all activesync contacts are wiped from the phone and no longer sync. Wiping the device and re-attaching to the Mobility server does not fix. We were on version when the problem first came to light and upgraded to GMS 2.0 upon suggestion from NTS. Still no help. Anyone else seeing this? If so, did you find a solution? Any ideas?
