very slow performance of Galaxy Grand 4.2.2 After the new update of 4.2.2 on Feb 6,2014 my phone performs very very slow.. cant even run a single application.. cant even pick up the call as the screen remains blank...
Smart phone has become absolute dumb and for no use...
I was facing the same issue after the 4.2.2 Feb 6, 2014 update. Did a factory reset and I'm able to run applications now. The dialing and answering the call problem is resolved, but on the whole, the mobile still lags.
