Knox Matrix is draining the battery and overheating the phone. Impossible to work that way. I hope that Samsung publish an update soon to fix this. I'm concerned that the battery can start expanding or leaking because it is to hot and i need to keep the phone charging to go thru my work shift. Really bad situation...

Complete piece of rubbish now. Used to last 2 days; now I have to charge it twice a day. And what are samsung doing about it?? forcing  onto phones that caused this problem, I will NEVER buy a Samsung phone again. I am stuck with this piece of rubbish for now, as I paid outright for it and can't afford to buy another just yet.

I also turned off the updates from them; the last one was bad enough. I dont need any anymore  on my phone. They even put games on it!! If I wanted games I get them myself.

I dont see replys below any help..Buy a charging portable bank like I have had to do is the only way to  keep your phone charged if you go out for the day as the UI 7 on it won't even last a day now.

I did find a bit of relief: if you clear system cashe. Turn off phone. Then hold power button and volume up until phone turns on, you'll then be in reboot mode. Use volume keys to select cashe partition, use power button to select, the power button to confirm yes, then reboot phone.
