I am using the NOTE 10.1 and my CONTACTS APP is not working anymore. All i did is selected a different gmail account for my contacts than before as i had migrated all my contacts to this account on my laptop. Someone disabling the current account contact sync feature and enabling the new gmail account contact sync feature has messed up the contacts app. If i type the name of the person in phone app then their data is there but if i access contacts tab from the phone or directly from the tablet its just a blank screen and after a while a message asking if want to shut down the app since it is not responding. Any suggestions on this guys? I have also formatted and restored the tablet to factory setting twice and the results are the same.
