I know this is posted already, but I too have the constant reboot issue and my s4 freezes constantly after the latest update from verizon. My phone was flawless before, now it is basically a paperweight. I cleared the system cache, but have not done the hard reset because many have and they say it didnt fix it whatsoever. I dont want to waste my time losing every customization I have set up for it not to fix the problem. I want verizon to come out and say, "We screwed up, we are trying to fix it now" But instead, they just tell their reps to tell us to do a hard reset. Thats the extent of their tech solving problems. Im sick of it. I didnt want the software, the phone was fine, now its garbage. They forced the update to their customers and should be held liable and responsible. I am currently paying for a service I really cant use through no fault of my own.
