Okay I will try to sum this up. My S3 was working fine and everything randomly I noticed issues with battery calibration It would be 100% then I would calibrate it and then unplug and then I'd instantly drop to 85%. Thought It was a battery issue and made a point to get a new one later. Then it kept working for another month or so then It started really screwing up the shutdown menu would randomly pop up and I'd back out of it.
Then randomly 3 seconds later the phone reboots. And it would keep doing that randomly I thought it might be a power button issue. Then as time goes on it got really bad to where it would simply reboot and not make it past the bootloader, It would not "reboot" more like a complete shutdown then I'd have to power it again and have it do the same thing. Seeing how I could not even make it past the bootloader I got a new battery, waited a week for it and then I put it in and the same issue happened. It would not get past the bootloader.
So I kept trying and trying and trying and it finally booted past that. And it stayed on for a whole night. I did everything on it I normally would and it was working great. Then the battery was getting low so I plug it in and was going to calibrate it after it was charged, I go back to it and it's dead again won't get past the bootloader once again. I'm completely out of ideas on how to fix this I pop'd off the button and blew in there and the button seems fine and everything still no change. I also can not get into recovery. It trys and loads but then shuts off. Anyway if anyone has any ideas on what this is or how to fix please help! I need my phone back! Thank you.
I'm running MOAR Lite version.
UPDATE: Took the phone apart and took a close look at the button it looks 100% fine...I saw a video on youtube that requires you to complete tear the button off and it works. But I don't know if the button is my main cause of this issue or if it will actually work. Some says it works, some says it does nothing...Please let me know thanks...
UPDATE 2: It will show that battery with spinning circle in it for like 1 second then turn off again. (When it is plugged in)
That's odd. But when it comes to the power button, dismantling and what not 90% of the time will show 0 issues. It will look perfectly fine when it's not. You playing with the power button I assume were pressing hard and normally to try testing it. It's a common issues on this version of the S3 to have faulty power button and you would need to get it repaired. Odly even slightly atmospheric changes can cause it to act different at different points. Some days it works fine, other days a very slight brushing over can cause it to screw up and trigger a manual shut down (holding for like 10 or 15 seconds).
Assuming that it is the power button, or to try, just do a variation of things to the power button itself. Use your finger nail to jiggle it around with different pressures. During boot if it shuts off, it could be the power button internally stuck, just jiggle it around.
This is all I can think of unless you bring it in to get repaired.
I was encountering the exact same problem. I would try to get into download mode and it would sit at the "Downloading" screen for about 5-7 seconds then the display would go blank. It won't make it into recovery either. Based on the above recommendation I took the whole phone apart and sprayed a lot of compressed air directly on the power button mechanism and the plastic case pressing the button in. I didn't see anything broken with the button when I did that.
It seems to be working now, I can boot into my Rom. Don't know how long this fix will last.
my phone was working fine until this morning it kept restarting over and over by itself. Normally it goes back to normal when I take out the battery and put it back in and restart the phone but when I would do that it would start to boot up as soon as I put the battery back in before I even pressed the power button. when I left it alone for a while it would stay on but the screen would turn itself on and if it was on to long the phone would turn itself off. when i managed to switch the screen to turn off after 10 sec the phone would stay on but still turn the screen off and on. Then I plugged it into my laptop and scaned my phone and found nothing. After that my phone was working fine and didn't shut itself off. I am able to use it like normal but the screen still continues to turn off and on by itself every couple of seconds. Can someone please tell me if there is a way to fix this?!!!

My tablet Galaxy Tab S 10.5 (SM-T805) screen went black. I can’t see the screen.
Touch also does not seem to work. However it’s on. it is receiving calls and other messages. It is connected to WiFi.
Power button, volume button are working but I can’t power off the device cause I can’t see the screen options.
When I plug in to the charging cable it vibrates but does not show anything on screen.
It didn't drop or hit by anything. i have been using it for 3 months now. it just happened by itself or may be by some update that I don’t know.
Please help how to bring it back to life
GUI crashed. Press Power+Vol up+Home (for approx 20 sec).

I tried several times.. nothing happens... any other suggestion please
Power+voldown+home.
If this does not boot, you could try with usb dongle.
Or full run down to empty battery.
Next chance would require to open it.

It's not bricked so calm down. It just had a cyber stroke. It will be fine just let the power run out and recharge the battery so u can turn it on again. Same thing happened within days for getting mine.
yes... I am waiting for the battery to be completely dead. so far its on...taking calls and sms..I don't howmuch % of batter is left cause I can't see it.
I had the exact same problem once....and i had a hunch that the screen was fine, it turned out it was thankfully....but....im aware that on 100 percent battery in standby it can last a good week or so....i was too impatient...so i ran my fingers around the edge of the backing and slowly was able to pull out the back of tge case and unclip the battery...worked straight away when turned on.
But also what i discovered does reset the tablet forcefully is holding power, vol down and the center button at the same time....try it a few times for a minute each time...if successful you might get a message about being in download mode but then just do the same thing again but imidiatly release your fingers once you see the screen go off from download mode or it will just go bavk into it...good luck m8
Have you tried holding down the power button for awhile, like 30 seconds? This should shut your device off....Then take it from there.

Seriously on my tab right now i just held vol down, power and center button whilst on and after 25 seconds screen went black then gave the "are you sure you want to enter download mode." Then i tapped vol up......t805 as well.
Battery completely empty.. tab S turned off, i plugged in the charging cable (1 ) battery meter does not appear (2) Power+vol does not work for me.. if it does.. i can't see because of the dead screen...
i have 2 options now..
(1) send it back in warranty.. this will take a lot of time and they will only fix not replace.. i guess
(2) open it and fix the display.

Hello,
Did you finally got some result?
I have exactly the same problem with a Samsung Galaxy Tab S 10.5. The screen suddenly went black although the light leds (home, back) were on.
I tried different combinations of buttons, usb charging and nothing. The only difference is that now the light leds are off.
---------- Post added at 08:46 PM ---------- Previous post was at 08:32 PM ----------
I have achieved to boot up the device because I have heard the start up sound and some notifications. However, the display doesn't work at all: the screen is black and there is no response when touching it. In addition, the light leds of the buttons are off now even when I push the home button.
Volume keys are working (I hear the sound then touching them).
Hard reset is VOLUME DOWN(left side on a 10.5) + POWER. Hold until it restarts.

That doesn't work, as sarhn007 said the problem is that screen is dead:

But I can't figure how could this happen in a new (2 month) high-end product... I think that I will have to use the product warranty with the cost in time it involves.
This has happened to me twice during the last year. The last time was just ten minutes ago. I tried everything mentioned in this thread. VolUp+Home+Pwr for a looong time. Just PWR for a long time. I saw on my Wifi Router that the tablet was connected, but no screen. What helped me was to do a combination of everything mentioned here. What eventually got the screen on was 1. I turned of my router and 2. Home+VolDOWN+PWR for (what I believe was) 10-15 seconds. Then I got the choice to do a normal restart or a device reset. If you come this far, be sure to press VOL DN when asked. Otherwise your data will be lost. Obviously, I can't say if the router pwr off was necessary or not.
What's really weird is that my LG G3 went into a boot loop at about the same time (less than five minutes apart). They are not connected other than using the same router. I've had my LG G3 for exactly one year without ever experiencing a boot loop. The LG G3 is rooted, but my SM-T805 is not.

It's easy fix, most of the time due to loose LCD cable. If you can hear anything on the background but blank screen, 99% is loose cable.
Remove the back cover, disconnect and reconnect LCD cable, make sure it's fully inserted, then secure the connector with tapes. Test by plugin to charger, press the HOME button.
If you do correctly, the battery icon should show up on the screen. Then put back the cover, you're done.

Hello, I've been using the T Mobile S6 Edge since the day it came out not had a single issue with it. Well today I unplugged it and used it for about two hours straight (browsing reddit in bed). I then turned the screen off and went to make a coffee, pulled the phone out to dial a number and nothing. Pressed home, pressed power, pressed and held home and power and power and volume up. Nothing. Just put it in the charger and no response. The heck is going on? Any help would be appreciated, Thanks.
Go to a tmobile store and exchange it. Same thing happened to a friend of mine.

Next time, hopefully there won't be a next time, this happens, try putting the phone in the download mode. Turn off the phone and press volume down, home, and power. Then press volume down not up to restart your phone.

OK I'll try that since that may have been the only button combination I didn't try. Thanks for the tip.
This happened to me also...Couldn't do anything with phone...Couldn't put in download mode or anything. .
Went to tmobile and needed my receipt so headed back home and then it turned on without doing anything

Yeah, what you're describing happened to me the other day. At first, I thought my battery died or something but ruled that out. Holding the power button didn't work so I figured I would put it in the download mode and restart that way. I've had this happen to me on rare occasions with other Android devices I've owned so I don't think it's unique to this particular device. It's just weird and kinda scary.
Cheers for the tip Vanessaem :good: My S6 refused to switch on & on my old phone S2 I used to just remove & re~instore the battery & switch it back on, but obviously we can't do that with the S6 so I was confused So I tried your button combination :victory:
For future reference, Vol Down and power for about 10sec will force a power down.
Hey dudes, check it out bruhs my phone is kinda acting up.
The story goes one day i was using my phone while it was charging, then it turned off and i thought maybe the battery is low. I left it charging overnight thinking it was the battery only but sadly it wasn't. I tried to boot it and failed. Now every time i try to turn on my phone it will shut off by itself. As soon as i put the battery on my phone it automatically boots without pressing any button and shuts off after a couple of seconds. (I've tried a different battery no luck still) Any help would be
much appreciated thanks a lot!:crying:
