So I was in love with this phone, and I had no sort of problem at all. THEN, I see the red and blue arrows so I had to update, which I knew wasn't going to do alot, but should help the phone out. It didn't. After it was done, my phone had the slowest lag I've ever saw, and when I would unlock the phone it gave me a static white screen sometimes before going to my home screen. Its horrible! I just want to go back to how it was, I had no mounting problems ect. Anyway to do this? Would it be the ODIN program? Thanks.
