Hello,
i've got some problems with several users including myself, when they have an android device running Android 4.2 or above.
Everything works except contact sync. It's getting some contacts, but not all of them.
I tried deleting and recreating the account on the device, but so far no change on any of the devices.
Debug account log gives me nothing, but i can paste that, if needed.
sync.log gives me this
2013-02-12 09:31:25,771 INFO [ZxMobile Handler Thread] [tid=17982;] sync - Sync[5634]: Sync on folder path: /Contacts
2013-02-12 09:31:25,772 INFO [ZxMobile Handler Thread] [tid=17982;] sync - Sync[5634]: Sync states are not equals:

Kind regards
