Why does my Samsung Galaxy Tab 3 keep shutting off?

The most likely culprit is the battery connection inside the device. I can only assume that the power interruptions happen while you are holding, setting down, or picking the Tab up. My Tab 3 10.1 would turn off and back on while I was playing a fighter pilot game; so I was moving and tilting it constantly. I thought it was the game until it did the same thing while watching a video, after just setting it down. It is just a momentary loss of connection. What you will need to do is take the tablet apart (carefully) and secure the battery to device connection. Most people just put a piece of tape over it, or criss-cross two band-aids over the clasp. I think it's pretty sorry that Samsung didn't do anything about this problem in the Tab 3, when the Tab 2 had the EXACT same problem.

"Same problem like a lot of people, samsung asked me to pay 160 euros to replace batery....but its quiet new..... shame on you samsung... you should response for your fabric falls.

Update

I fix it !,,,

.. so i opend the plastic back of the tablet and changed the protecting tape on the batery contacts. I put 3m Electric tape! It had not switched off 4 days now. Hope this helps some of you"

"Hello Lynne,

It sounds like your battery could be going out, if you have had it for about a year and a half or so this would be right on schedule for it crap out.

However before going about replacing the battery I would back up all your information to your sd card. I use mybackup free should work for your case or upgrade to pro to access the info from other devices or use cloud storage. Then go into settings and find the reset tab and factory reset your device then load your back up and see if that helps! If it doesn't I can help you further with the battery replacement!

Hope this helps!

:if you find this helpful please vote up the answer to aide to my rep, I will do the same!

Thanks Lynne!"

I had the same problem with samsung tab 4 10.1 it kept turning off and on was driving me crazy sent it back I bought a new Samsung with the money it done the same turning off and on then I realised it was the magnetic case cover that was causing it lol

I found the magnetic book design cases for the tablet caused the tablet to go into lock the screen mode when I bent the case behind the back, it happen every time when I took case off I had no more issues I hope this helps anyone with this same troubles I know as how frustrating it becomes after awhile not knowing what's going on
