My Tab S 10.5 froze up after a game of Battlefield 4 Commander. I can turn the screen off with power button and the automatic screen off works when I close the logitech case it has. But other than those, nothing works. I am unable the close the game(it is hung on the startup screen), cannot go to startup page, change volume, nothing. Tried plugging on the charger(the screen does turn on, but nothing else). Advices are more than welcome.
edit: running on stock nordic rom, no roots no nothing.
edit2: got it to work, force reboot is power and both volume buttons(or just press in the middle)

Ok so I had installed a home replacement called qq launcher version 1.21 and uninstalled around 10 min after. While it was uninstalling, the loading bar kept going and the phone froze up. So i took out my battery and proceeded to turn it on again. Now when my phone turns on, after booting up it goes to my pattern lock screen with a completely black wallpaper and my phone freezes. When I press the power button, the screen goes black and stays like that. The only time it switches is when i plug in my charger and when i do that, it goes back to to the same lock screen and stays frozen unless i press the power button (which turns my screen black again.) Im running gingerbread 2.3.4 and im not rooted. My phones also disconnected so i only use it on wifi. I would really REALLY appreciate it if someone can help me get my G2 back to normal, i depend on it greatly whenever im on a wifi network.
With the phone off, hold volume down, press and release power. This should pull up the bootloader screen. You should have the option to do a factory reset from here. Try it.
Hi everyone!
I rooted the Tab S + installed Xposed (Xprivacy and Gravity box).
No issues with that except the wifi password being lost upon reboot (had secure storage set to false in /system/build.prop with no effect really).
Then during reboot, after the first screen (the one that say Galaxy tab S),while there's the animated Samsung logo showing, the tab froze...
Now I have the screen showing Samsung, pressing the power button , the recovery or download key combination does nothing...
On My S5 I would have removed the battery but here it's not possible so I'm waiting for the battery to be empty...
Any idea how to force the shutdown?
Has any one tried to open the tab to remove the battery?
Thanks !!
Press and hold power till screen turns off. Keep holding....

I've been trying that for 3 minutes straight...
it's not working...

Press and hold power, volume down and menu button. You will get to the fastboot page.

Hi,
So none of the hardware key combination ( to reboot in recovery or in download mode ) worked.
After a while , there was no energy left in the battery so the tablet did stop.
After some charging, it rebooted as if nothing happened :silly:
And this time, no https connection worked (no google play, drive connection possible..).
So I did a factory reset, rooted ( this time , the wifi password was not lost),install Xposed ( with gravity box, Xprivacy and App settings).
Now everything is working fine :laugh:
I have no idea what went wrong in the first place, I hope this thread might bu useful to someone !
Thanks !!

Thanks! This worked for me after having fiddled with resolutions in ROM Toolbox Pro. I had "System UI" and some other app crashing in a tight loop, and holding power button down didn't make it shut down, ever.
It looks like now I'll have to reflash it with Odin, but at least I can get there without having to wait for it to run out of juice
Cheers
I have a Samsung Galaxy Note 10.1. I can't figure why my tablet won't power off. Everything seems to run fine.
When I press the power button, then press (select) power off the tablet goes thru the motions of shutting off.
It actually shuts off for a second, screen goes black and off. Then it restarts. I get the logo etc. Then back fully on.
I would like to turn it off other than just go in eventual sleep mode. This tablet was never modified in any way. It has a stock ROM never been rooted. I also looked at the running apps and everything seems normal. Any idea would be welcomed other than Hard reboot.
Thanks for the help.

Is the tablet plugged in? Otherwise hard reboot is your only option.

Even if it's plugged or not same weird thing happens. As if I restart the tablet when I in fact power off.
Problems with my Samsung Galaxy Tab S 8.4 SM-T705:
1st: October 2014
2 weeks after buying, my tablet's battery drained overnight from 45% to zero. Next morning, I turned my tab on after charging to find out that the Tab starts but without any Samsung GAlaxy Tab S logo or Samsung Logo and the Screen has turned green, rendering it difficult to read in auto brightness mode or low brightness mode.
I restarted the device 2-3times and the device started working normally. This was my 1st device restart. I never used to power off the device before.
In 1st 6months, this greenish display problem n logo problem occured 2-3times, and i ignored it, because, it used to get resolved by itself with restart and I had no service centre in and around 50km to my work place.
2nd: January 2014
My device all of a sudden stopped working.. actually hanged.. I managed to turn it off but failed to restart it.
Later I realised that the device has restarted, but the screen was not responding when the screen blinked for a moment with the opening of book cover.. and the back cover of device was warm..
Googling taught me the way to access recovery screen n I opened recovery mode with "power+vol down+home key" and pressing vol down in recovery screen to restart tab.. again the tab started working fine..
3rd: Lollipop update: May 2015
I did Lollipop update. The device was smooth to operate at first. But gradually, i noticed that unlocking the tab failed to light up the display everytime, just the soft keys lighted up. But one day, the device freezed with no response from touch screen. I was unable to switch off the device also.. I had to drain the battery by playing music using S voice to turn the device off. "power+vol down+home key" too was not working.
On googling, I learned to reset device with "power+vol up+vol down" keys pressed together. finally the device restarted, but the device used to hang occassionally.
Googling let me know that i need to factory reset device upon firmware update for normal functioning, which i didn't do after update. so, I backed up my device, uninstalled many apps to make the device run a bit smooth and did a factory reset.. Resetting didn't improve the situation much, but now, the device display failed to light up on a regular basis on unlocking most of the time..
Now the situation is that, the device turns on, finger print scanner works, all apps n everything working, but display remains black, and touch screen is not responding.. using sidesync, everything on Tab can be accessed via laptop.
Tricks tried:
1) Factory reset
2) power+ vol up+vol down
3) power+ vol up+home key
4) power+ vol down + home key
5) Power off using sidesync and then restart
Results: All failure. Everything works but the display never lights up normally..
Plzz help....:crying::crying:
Bump. I'm starting to have similar problems with my SM-T800 running 5.0.2. I open the cover and the device fails to turn on. I press the power button and the screen stays black but the notification bar turns on. I can shake the crap out of the device and the screen stays black but I can see the notification bar flicker. Driving me batty.
If i had any problems like you guys, I would just return it to the place i bought it, for a refund or replacement or even a repair, post it to the service centre if it`s too far to travel too.
You problems sound like battery and or loose connector inside your tablet, it happens frequently on Samsung tablet for the connectors to come loose, if the tablet is dropped or twisted, no outside damage might be seen.

Hi, I was just playing around with my LG G3, (I'm using Nova Launcher) and I found "Guest Mode". I turned it on, and it changed the screen to the default lockscreen, and then the screen just went completely blank. The led flashes blue if I press the power button, and I can turn the screen on and off because I can see the "Retro TV fade out effect" when I press the power button. I can't turn the phone off via the power button as nothing come up, it's completely blank. I would like to avoid anything which involves me losing all my files and data. My carrier is O2 and I got it in April 2015. Please, help me!!!

that's a weird situation, i could assume you tried removing the battery, try connecting your phone to the pc if it opens run a backup and move your files to the pc, and flash the software via kdz in download mode. (apps will be removed).
