Hi guys.
My Galaxy Note 3 power button has just completely stopped working. Is there a setting that turns off the power button functionality that I might have accidentally pressed?
Cheers.
Edit: I should elaborate here. The phone is switched on, everything works as normal but no matter how many times I try it, the power button just not do anything (holding it down, pressing different areas)

Did you try a battery reset? With the phone off, can you get into either Download or Recovery mode? That would eliminate the possibility of an OS issue.

I kind of scared to turn the thing off in case I can't switch it back on. I'll try it though.
Edit: It's dead. Taken the battery but can't switch back on now. What a joke.

I know I kind of expect this bad luck these days after having two faulty Nexus 7's. My Galaxy S2 power button is still going strong after 2 and a half years but the Note 3 lasts 7 hours

It's a dud mate. Faulty unit.
Just send it back and get it replaced.
Just send it for replacement. There's a reason phones come with a warranty that covers manufacturer defects. Whining about it to strangers in the forum is not going to fix it for you.

Yeah this is definitely the least friendly of all the Android forums. Sorry to hear you have a dud unit mate. Get it replaced.
My power button is not working to turn the screen off. Long press works to bring up the power down menu or to do a hard shut down. It works to turn back on though. Seems to happen after I plug it into the wall charger. Restoring a nandroid backup fixes the issue.
Not sure if it's related but my PC's USB crashed after trying to plug the phone in and use USB 3.0 to transfer files. I had to refresh my W8 PC to get the USB working again.
I have the Sprint version, rooted and running JellyBomb.

I have the same problem. my power button is done for. whenever i need to start it. I plug it in and go into recovery and reboot from there. I also use this https://play.google.com/store/apps/details?id=com.plexnor.gravityscreenoffpro&hl=en for screen timeout and lock. And you can also get exposed and gravity box and there is a status bar tweak to double tap the status bar to lock screen (put phone to sleep).
I tried everything then found the solution on another website
My note 3 has been with me for almost 2 years now and it's power button stopped working about 2-3 months ago. Until now I avoided draining the battery below 2% and was fine but just today I dropped my phone and it shut down. I knew that my power button didn't work because of hardware problems so a soft reset didn't work for me. What I found however is that if your power button is dead you can just very quickly remove and re-insert your battery and your samsung device (I have no idea if this works on other brands) automatically boots itself. I'll give the link too incase I wasn't clear enough and I hope this helps people who shared my worries.

Anybody knows what's wrong and how do I solve it? Here's the entire story (if it helps):
I went to Play and updated my apps. I press and held the power button and selected "restart". (I restart my device regularly) However, after shutting down, it does not boot at all and no matter how many times I press the power button it just wouldn't boot up!
I tried charging it too. Nothing happens even after plugging in.

Can you get to the boot loader, if so, try to wipe data from the recovery within the boot loader.
Or else leave the battery to drain fully , this will solve your problem and the tab will boot.
This happened to me couple of weeks ago and draining the battery solved this issue.

May I know how do I get to the bootloader? I can't even allow the battery to drain. The problem is it is not even starting at all. I pressed the power button a million times and NOTHING happens at all, the screen didn't even turn on.

Nope. I wish it did.
Try to hold the power button in about 4 or 5 seconds. I doubt it'll do anything. It sounds like there's a problem with power button or hardware.
I had a thrive 7 before I got my gtab 7.7 and my first one I exchanged because of a problem identical to yours. It was very sketchy to power on.
Exchange or warranty if you can unless someone else has any ideas

Only alternative left to leave it till battery drains, if you can remember the battery percentage before this happens, otherwise i am out of solutions.
A service center would be an alternative choice.

I decided to give it another shot a minute ago and it miraculously worked! I have no idea what's wrong or what caused the positive issue but am happy that it is fine now. Thanks guys!
I have had my Focus for one year now, and last night it shut its self off and will not turn back on. It has randomly shut off four or five times in the past two weeks, and I thought it was a hold button issue because I would go to lock my screen and nothing would happen, and then a few seconds later it would show the power down screen. I would always swipe up to navigate out of it but sometimes it would end up shutting off anyway. So now I can't get it to start up by pressing the hold button, but when I insert the battery it will show the Samsung screen for a few seconds and then shut down. Any Help ?

It is either the power button or the battery. Search the forum for "power button" and you'll get threads with similar issues as yours. In most cases it is the power button, though.
^ Do you really think its power button issue? Because once in a while when i press the power button the phone starts but will shut down after the samsung logo.

How many seconds after starting up does it shut down?
Do this test: when powered down, lean the phone so the power button is pointing to the ground and tap a few times on the phone (to unstuck the power button). Then connect the power from the outlet (to start up the phone). Try this a few times. If it starts up normally even once, then your problem is the power button.

6 seconds sounds like the power button stays pressed, turns off as it would be kept pressed.
Sorry mate, good luck with that. Look at the other threads, there are a couple of repair tips there.

Finally i got it fixed. It costed me around $30 US dollars. Service center guy told me that he did the following
1) Replaced ON/OFF Switch
2) Replaced charging connector which was burnt.
I recently bought and used Batteries from ebay.com and they might screwed the phone? no idea..
switch failure has nothing to do with dodgy batteries but just shoddy workmanship from sammy, much like the sgs3 which also equips another horrendously fragile on/off switch
by the way, did they replace just the internal microswitch or the switch as a whole, button and all?

I got this fixed in Elephant House, Ameerpet, Hyderabad, India. This is NOT an authorized service center which I got this fixed. But this guys screwed up my volume button... I can increase the volume but not decrease.. I dont want to go to the service center again as its very far from my home.. Any app which can decrease the volume?
Note :- Its NOT a software problem ..Service guys did not reset or make changes to the phone related to software/OS.

Hey,
I've searched this forum on others but haven't found anyone who've had my problem.
I have an original GT-i9500 purchased a little over a year ago around the launch. The phone was rooted and had a custom ROM installed. (Crash ROM). I have installed the ROM about 3 months ago, and haven't fiddled with it recently. I've had CWM installed.
Yesterday I've noticed that the device went into boot loop all of the sudden. I haven't done anything unusual when it started boot looping.
I can see the Samsung logo for a couple of seconds, but then the screen turns off and the logo comes again. Loop. Trying to enter recovery mod (CWM) doesn't work. Phone keeps looping. Trying to access download mode does work partially. I can get to the screen where it says "Warning!!" and asks to click "volume up" to continue. But stays on that screen for a few seconds and then boots to the logo again. Happens whether I click "volume up" or don't.
I have no idea what caused this. But shortly before it started I did see that an app that uses wanam was updated (bubble UPNP) and there was some notification about it from wanam.
any help would be greatly appreciated. Thanks!
You have eaither a malfuntioning power button, a faulty battery or some other hardware failure.
This is not a software problem.

I have exactly the same issue, tried plug in power supply, shows an empty battery icon with circle in the center, stays for a few seconds and screen goes blank. It repeat this process if i keep it plugged to the power supply.
Just an update in case anyone ever finds this thread and is experiencing the same symptoms. It was indeed a faulty power button. Having it replaced has solved the problem.
It was apparently stuck on "pressed" mode (not physically, i would've noticed that). Another indication for that was that putting in a battery would automatically turn the phone on.
i know it was before a few months back,
but anyway... i got the same issue too, but my phone was on stock rom without root.
this is random annoying issue...
as i understand from you guys, i will need to take the phone to a lab to fix this, bummer!
thank you any way...
same problem here..
just got this issue today.. cant go in download , cant go in recovery, wont boot...
i was using it just fine when it just turned off...

Faulty power buttons, faulty power buttons everywhere.
I fail to understand how samsung does this. This has been like the 500th stuck power button issue here.
Looks like we have to add it in the guide.

I've got my phone back from the repair service and it was indeed a failure of the power button electric circuit,
(i don't know exactly how to translate it correctly to English, but they say something about secondary electric circuit board)
anyway, it been replaced and the phone came back to live again
I got it fixed today..
I think it should be added as a major cause for bootloop, if you cant open recovery or go to download mode
at first i thought my phone was bricked but then after some hard searching i found out this thread and proceeded accordingly..
I opened up at the phone and checked the power button myself with my instruments.. then i took it to repair center and told them to replace the power button... simple as that.. cost me 9$

The easiest way is plugging the usb cable (which is connected to your computer) to your phone while holding volume down button. No need to press power button. From download mode you can boot to recovery etc with the help of your pc.

did not work
This sounds more and more like a case for Yota's repair center. If there wasn't something broken in the device one of these methods described in this thread should have worked.
Sounds like hardware to me.
I had the same issue. Left it on the table with the e-ink screen on top, came back hours later, the clock was 90 minutes behind and the phone dead. Resetting with 10 Seconds ON/OFF button didn´t work. Had to send it in. 2 weeks later got it back. They said they had to change the whole motherboard, even got a new IMEI with it. Then a few days later I tried the main camera and it did not work, error message by Android, unaccessible camera... Then by pressure on the camera it worked sometimes, sometimes only misty lines, sometimes splitscreen mode, sometimes not. Maybe a mistake by the service while reassembling the phone? Anyway, had to send it in AGAIN, got it back, sold it on ebay with 130 Euros loss and bought a new white one because I love the principle and options of the second screen so much. The white one is a newer batch, they say with some new (and probably more reliable?) hardware, so up until now I am completely satisfied, no error for 6 weeks (fingers crossed...)
My old black one was maybe a monday batch

Hi Petra. Since you're using a Yotaphone as well, could I ask you to do a small favour for me please? After I had my YP rooted I accidentally deleted the system app "back screen manager". My back screen has stopped working since then. It'd be fantastic if you could just extract the system app from your phone and send it to me so that I can manually place the system app on my phone root folder. You don't have to root your phone for this. All you need is an App extractor from play store. And it will take less than 5 mins to extract and send it to me(Assuming that you are well versed with android OS). Here's my email address [email protected] or you could send me a link to the shared file. Do let me know if you are willing or not. Thanks a ton.
Greetings fellow geeks.

it keeps resetting every 4 seconds.
won't let me go to recovery.
i can go to download mode. but it won't respond to volume button, and resets after 4 seconds.
i have a custom ram on it.
if i place a battery back in, it will power on and keeps resetting every 4 second.
what should i do?
Maybe your power button stuck in? But if you can enter download mode then not I guess. You can always flash original firmware if you haven't necessary data on it.

Ok sorry my friend, read that you can use download mode well. I think there is something with your power button. Did you drop your phone? It shouldn't reset every time in every state, that looks like hardware failure. You can easly open your phone with little screwdrivers, but you will lose your warranty. If your power button is broken you can always order new ones from China, I did it with $1,3 (power and volume).

No it's your power button for sure.
I had that issue with my S3 LTE. It is indeed the power button since it does exactly the same that my did, try to use some alcohol in a swab and pass on the button (let it penetrate the button area, next click several times to try to clean the button from inside).
Good luck.

I have the same problem with my i9505, I always fix it like this:
1) remove the battery
2) let the phone rest w/o the battery for min. 10min
3) put the battery in and try to go in recovery
4) if you can wipe cache and try to turn it on
If the problem happens again:
1) remove battery
2) short the pins like this x/-/x/- , then x/x/-/- and then -/-/x/x (x is the connected pin) with something that conducts electricity like a metalic ring or high resistor or s/t
3) do step 3) from the previous one
(Anyways what you do is that you drain the capacitors in the phone, and on the power button, that capacitor is the main problem)
If that doesn't help, then try to leave it w/o the battery overnight
EDIT: well that is not a permanent fix, the fix is probably that you need a new power button, or in the worst case a new phone
