回答“Why does my Samsung Galaxy Tab 3 keep shutting off?”Hi Folks.I am Franco in Stockholm. I have a galaxy tab pro 12,2 sm-t905 that love to turn off at 87% as well as 49 and so on. It keeps rebooting all the time and as soon the screen comes on,it shuts off and reboots all the time. So after rebooting 5-6 times I cleaned the screen from finger grease and it kept working fine until 47%,when it started to reboot again. When it starts shutting down I attach the power cord and all is well. THIS morning it turned off at 90% more or less so I testes by TURNING RHE DEVICE FROM HORIZONTAL TO VERTICAL POSITION and now the rebooting is gone .I am now down to 35% and all is well so far. I have had this issue for a long time and also changed to new battery only som months ago without no improvement. I hope this test is helpful to me as to you all out there. PS: I just love my tab,so I would like to keep it for a long time. Perfekt size for home and travel as in the car. Best buy I made.
