Every since the 4.3 update my phone keeps freezing, the battery drains pretty quick even if the screen is locked, runs very slow and other minor issues. Is there anyway I can fix this? This is the first android phone ive had so not to sure how everything works yet. I have to admit this is the worst phone ive ever had but unfortunately stuck with it for another year and a half. Aslong as I can get it back to working as it should it will do
