I used to love my SG4 but this recent patch to 4.3 and has done nothing but mess up my phone. My battery life is terrible now, my phone seems to overheat or get hot now. I have my phone set to screen time out after 2 minutes and often at night I will wake up and my screen is still on. Lately my phone has been locking up making me pull the battery to reset it. I recently did a full reset after 4.3 and my phone is still giving me a headache. It's not enough to make me want to go to Sprint and get a new but it's just enough to start bugging me now. I'm hoping we get kitkat asap and i'm praying that some of my problems will be fixed with that update. I may even need to root it , which I have never done but I am considering now to hopefully alleviate some of my problems.
