Hi all
bought used phone worked well 4 days now is stuck on S view mode. It means screen wont go into sleep turns on back 3 second after sleep always. Only way how to turn off the screen is that I have to put a small magnet on the phone and I can see S view lockscreen for about 10 seconds and screen goes into sleep. Home button wont wake up the screen. When I press power button S view lockscreen is shown. When a magnet is removed the screen lites up and phone works without problems.
So far I reflashed official ROM no help Factory reset no help tested all sensors all good. Phone has no warranty. Any idea what to do. Thanks for any input

Strange issue
a new samsung s4 mini, stock rom.
the screen will not turn off. whenever it enters sleep mode, the screen blacks out for a second, then turns back on.
this happens when it goed to sleep automatically, or when pressing the powerbutton
tried factory reset, same problem (no extra programs installed)
installed a wakelock ap, but that does not really show a reason why it should be turning on?
Anyhting obvious i am missing, or should i just return this to the dealer.

Have you installed any app like "Screen ON"?
I ve got this problem from time to time, when I lock the phone it wakes up for 5s and then turns the screen off although I have had twice the situation where the screen was on all the time till I pressed off button again...strange.
Had this problem long time ago with Note 1 and somebody said that the phone wakes up if it looses the signal and searching for it again......
dont know......
Im not really sure but might as well try.
Have you turned on Daydream ?
You can find it in Settings 》My Device 》 Display
Make sure it is off.
If that hasnt worked, if you have a cover on take it off and then see if you still have that problem. Maybe the cover is too tight and its presing on a button.
If that doesnt work, then now lets turn off Smart Stay. Swipe down your notification bar and look for Smart Stay and turn it off.
If none of these have worked then I'm not sure :/
Hope your problems gets fixed.

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.

I updated my tablet 2 days ago and ever since my display will not turn on again after I lock it or it goes to sleep. Everything works fine if I restart and I can use the device normally until the display shuts off for the first time, after which I cannot get it to turn on again. The capacitive touch buttons light up when I touch the screen or the home button as they normally would. I have tried a factory reset and it has not fixed the problem.
Does anyone know what might be the cause? I have never rooted the device.
Good afternoon all, I'm wondering if anyone can help.
My Galaxy Tab Pro 10.1 developed an issue with the screen (after travel - where it may have been knocked around a little)...
The tablet boots up fine and the screen appears to work normally.
However once the screen times out and switches off, or the screen is switched off by the power button, it is not possible to get the screen back on.
It appears that it's just the backlight that is not coming back on?.... as the screen responds to touch (you can here the pin code buttons being clicked).... but can't see anything at all on the screen.
Rebooting the tablet from here makes the screen come back on as normal - so as it works like this and just does not come back on after being 'on staandby' I thought it might be a software issue... I did a full factory reset but unfortunately the problem is still exactly the same.
I've had the tablet to bits to see if I could see any cables loose or anything - but everything looks ok - I think (Although it's the first time I've had one apart and wasn't 100% sure which cables were for the screen)
There was nothing obviously disconnected or loose.
Has anyone come across this fault before or can anyone provide any more guidance? Maybe a particular cable to check or how to check it?
Many Thanks,
Tom Leitch
I have the same issue, but I was able to fix it entering the factory mode and pressing the sleep button. That was possible using the calculator and entering (+30012012732+ and then entering *#0*# to get to test mode.
The problem now is that I'm using lineageOS so I don't know how to get to that menu or trigger that sleep button. Anyone?
