I set the time daily on my tab. 4 10.1 and it will be wrong by 2 or 3 mins. the next day.
Go to settings, then to date & time under system, and select automatic date & time and automatic time zone. This should fix your problem. I hope this helps.
Amazing, but the simple apn update fixed it for me.
Go settings ,turn off auto matic time zone, options available time zone , and click, select country , India’s any famous city came like Kolkata, delhi select Kolkata or other , click , and success
I live in Thailand and it is not indochina time zone. It is wrong. Automatic time is not help. Aliza
