Ever since the update I had the same problems as well. Re-occurrence of overheating also resulting to slower app interface, battery life significantly decreased even though there's limited usage, and very significant decrease in charging speed. Before the update, it takes me just 2-3 hours to fully charge. But after the update, it took me 5-6 hours to fully charge. Please help me with these issues. Hopefully this "bug" can be fixed ASAP.
