Answer to: The Tab is in an endless reboot loop.I'm 90% confident this is a hardware issue. Here's why... This problem only starts once the battery is lower than 50%. The screen will flicker a few times just before the reboot -- especially when swiping the screen. The reboot will continue until the battery gives out OR you plug into external power source. Plugging in ALWAYS resolves the reboot. I've tried clearing the cache -- no change. Once the reboot starts it will not stop until you plug in power. Some people say that doing a factory reset will fix the problem -- This is not a fix. This is a cop-out. Uninstalling high-battery usage apps might help resolve the problem but the *real* problem is the battery does not keep a consistent output after half discharge.
