NEED HELP. Power button stuck. - Galaxy S3 Neo Q&A, Help & Troubleshooting

My power button gets stuck and as you know when you long press it it reboots the phone. So basically my phone is just constantly rebooting and rebooting, its practically unusable. I need help if anyone knows a way to disable the function of power button, I mean so the power button wont do any function anymore, or swap it with another button.

I had the same problem. Got the button replaced, it worked for a month or so and I started getting the random reboots again. A search on the internet reveals that this is a common problem with the S3, and I doubt they fixed the issue for the S3 neo.
1.5 years of use and my power button is broken, my volume buttons are mushy and my camera doesn't focus at all. The build quality on this phone is a joke.
You'll probably have to have your power key replaced as well. Or do what I did and remove it from the motherboard. You won't believe how flimsy the solder is. I now use the accessibility shortcut button to lock / unlock my phone. It's a hassle and it takes up screen real estate, but at least it works.

Mine stopped doing it now but I'm sure it will start again. You are right, build quality of this phone is really lame. That part on the sides that looks like metal is mostly worned off from my phone. Camera focus is crap and volume is lower than before, I can barely hear notifications. Maybe I'll remove the button too, but I'm concerned about how to boot the phone if it turns off.

You can turn on the phone by connecting the charger, immediately booting into download mode (before the battery icon comes up) and restarting from there. It's not the best solution, but at least I have a functional phone until my oneplus x arrives sometime this week

That's actually a fantastic idea. I thought about flashing cm that has no offline charging and booting that way, but this is better solution lol.

You can try nova launcher since it has a gesture for double tap to lock screen, or maybe a 3rd party app.

use soft lock to lock screen without pressing power button

Crazy volume problem

Basically, it is as if the top volume button is held down, and the volume is continuously going up on my HD, even when I try to turn it down, it shoots back up again, and is stuck on the volume screen. Sometimes, if I turn it down to silent, it will stay silent for a few seconds, then the volume goes up again and keeps going up.
Really annoying as it means the phone is basically unusable as I'm pretty much always trapped in the volume screen!
Any ideas?
I would suppose that a button is stuck!
Take of the back cover and take a good look at the buttons to see if anything could be wrong!

That's what I thought, but it looks fine to me
I had the same problem as you but I then realize that when I was putting down the volume while in a conversation was my face pressing the screen and increasing again the volume...could it be your same problem?

Nope, because it happens if I don't touch the phone and just leave it on the table
Have you tried a hard reset?
Do a backup first.
Turn off the phone. If you can't pull the battery out.
Hold the volume up + down at the same time then press the power on button for about 1 second. Let go of the power button while keeping the volume up and down still pressed down.
You should see a blue / green / red screen then just follow the instructions on screen.
If this doesn't solve your problem then most likely something is keeping your volume up button depressed internally. Take it back for repair...
The volume slider malfunctioning is a big one on HTC devices known issues. I've had the same problem with my elf....and I've seen plenty that do too. Your best bet would be to take it to an authorized service rep. Sucks I know
Try to remove the cover and use it... the pressing mechanism is on the cover...

Tried that, still the same problem.
I'm going to try a hard reset today, if I still get the problem, going to ask Orange to replace it. I wonder if they'll let me pick another phone, I'm getting a bit fed up with the HD!
I have the same problem, it occurs randomly and I discovered that if I quickly press the power button to stand by the phone and press it again to exit from stand by, the volume bug disappears and phone starts working well again. I thought it was a software bug but I still have it on 1.19. It rarely happens now on 1.13 was more frequent.

Disable Power button when in pocket?

Maybe a stupid question,
Does any one of you have a solution for the power button that keeps turning my i5800 off when hes in my pocket? Even when in locked screen, and i long press my power button, he just reboots .....
Nobody has issues with such a phone in he's pocket?
i was thinking about a hardcase or something, dunno if its gonna help.
Is this issue know among you people? If so pls tell me what you did about it

Robin

Ok so far i managed to edit my keymap layout, and removed the wakeup flag of the power button, this already prevents the powerbutton to show the Phone options when in locked screen mode.
This way he can't change he's airplanemode or something similar.
Only thing i still not understand is the power button behavior when you realy long press it. The phone automaticly shuts down complete. Is this hardware controlled or software controlled?
Nobody knows anything more about this?
Something can be done
Like disabling the power button temporarily by proximity sensor
An app could do this
i'm also looking for a solution with this damn power button...
if i have got my G3 in my pocket it happens quiet often that it turns itself off cause screen lock doesn't disable the power button
does anyone have a solution for this prob ?

The tasker app, could probably pull that off:
https://play.google.com/store/apps/...EsIm5ldC5kaW5nbGlzY2guYW5kcm9pZC50YXNrZXJtIl0.
Its a paid app though. You could try to setup tasker to react to tilt sensors as well, an example would be: Tasker disabling the power button when you phone is upside down (like in your pocket). Hope it helpps
For people who have the problem of the power bbutton when in their pockets- Just put in upside down . I get the problem many times so I put the cell phone in such a manner that the power button is facing the top and the camera is touching the fabric of the jeans. Thus making the power buton free from any contact.
Works for me.

@ak700:
power button is facing top, display is facing to my leg that's how i have it in my pocket.
i guess that's the same way as you described isn't it ?
^^^^
Yup thats the way. It works for me even in slim fit jeans too.

Lomg pressing thr power button on a gg3 restarts it, it doesnt turn it off(if you press just one second longer)

That behavior can't be turned off. It is basically our "hard reset", to be used when the phone won't react to anything (instead of having to pull the battery). Even though I don'tknow that for sure, I'm fairly certain that this is hardware controlled. Out works even if there it's a kernel panic (better known here as "black screen of death"), when the system doesn't do anything anymore...
Sorry

[Q] Touchscreen not working on lock and reset screens

In the last couple of weeks, when the pattern lock screen is displayed, it intermittently doesn't accept touch input. If I power off and on the screen quickly, it then accepts touch input fine.
Similarly, if I press and hold the power button (with the phone on), it brings up a "Phone Options" screen, with options for Silent, Airplane, Profile, Reboot and Power Off. Touch input does not work at all on this screen. I'm working around this by using the Quick Boot app.
Otherwise, touch input works fine, so I don't think it's a hardware problem.
I've seen something similar when Google Nav gets in front of the lock screen. Touch doesn't work until I power off and on the screen, and enter the lock pattern. Could something invisible be getting in front of the lock and power screens?
Using Pongster's HyperDroid-GBX-v12 (2.3.3).
Hey there,
Maybe the ROM h doesnt function properly on your device. Try shifting to another rom. All are equally amazing. If you do not want to shift, try running task29 and start the process all over again

Have you read the thread about the unresponsive touchscreen, where pressing hard on the end call button fixes the screen touch? I assume your problem is in essence the same; once you press it hard enough to actually unlock the screen the touch works fine.

That probably is what the problem is. Btw to everyone, I haven't noticed a difference in pressing it really hard, I noticed that pressing it a lot of times does the trick

Thanks for the feedback. I don't think it's the ROM, been using GBX-v12 since it was released, and previous versions before that.
The symptoms do seem similar to the other thread, but others report it on many screens. I only get it on the lock and reset/power screen. Otherwise, it works fine. However, those screen are brought up after pressing the power key ...
I suppose if it is hardware, then it's likely that cable issue. If it's software, then a reset should clear it, so I might try an ICS ROM from scratch first.

I guess i shoulda commented that how my digitizer began acting, it only did it while in the power menu but after a couple days it started doing it while just hitting the power button to put it to sleep, so i remapped my green phone key to be the power button

Thanks for the tip. You're right about the symptoms getting worse, it now occasionally stops working on other screen
I'm using any button but power to turn on the phone. To turn it off I've added "Go to sleep" to the notification widget bar, which I assume is the same as pressing power??
Not quite as user friendly and sometimes I forget not to use power off, but it'll do for now!

Yes that will work! I used it cause I got lazy and didn't feel like changing the key file but it's much easier to use the green call key instead of the notification power widget

Try this:
Lock the screen normally, screen turns off.
To turn it on again by pressing any other screen buttons other than the power button.
I found that if I do it this way, the screen runs normal.

Focus is dying, what could it be?

i suspect the power/lock button is FUBAR, but there are some other symptoms that do not resemble just a bad power/lock button. here are the symptoms that indicate it is the power/lock button:
1. when the phone is off, almost impossible to turn on. sometimes have to press and hold power button 10-12 times before it will shut on
2. when the phone is on and i press the lock button to lock the phone, most of the time it thinks i held the button and says "slide down to power off" although sometimes it doesn't respond at all. it almost NEVER locks when i press it (like it should be doing)
3. when the phone is on and i press the lock button to unlock the phone, most of the time it shuts off completely and i go back to step 1
symptom that indicates another problem not related to power/lock button:
1. if the phone is off and i press the power button, when the phone responds it will sometimes say "samsung" like it is turning on, and then nothing else will happen. i won't get the ATT screen and it won't boot up. this some times happens multiple times before the phone finally boots
currently i've been letting the phone time out automatically instead of the lock button, and using the camera button to unlock it. i've also been trying to not let it turn off at all, because getting it back on is really tough.
is there anyway i can disable the lock/power button...and/or is there an alternative way to lock and turn on your phone that doesn't require the use of that button? even if i tell myself not to use it, there are still times in your pocket where the darn thing gets pressed. for me that could mean it kills my phone and doesn't restart for the rest of the day, which i'm sure you can imagine is not ideal.

You seem to have a (hardware) problem with the power button (obviously).
There are a couple of ways to turn on the phone/display without the power button:
- camera/back
- connect power charger
- usb connect
Last 2 are not practical and first you already do. You should try and see how much would it cost to replace the power button, if you're out of warranty. Should be cheap, and beats workarounds.
is there any way to lock it rather than letting it just time out? what about turning it on?
do you feel pretty confident that the seemingly unrelated symptom where the "samsung" screen comes up and then shuts off while trying to turn the phone on STILL indicates the button is broken? just worried this problem extends further than just the button.
thanks for your help.

There's no other way to turn it on (except plugging it to charge) and you found the one workaround, with the camera.
I am *very* sure that the power button is the culprit in your case, most likely the spring that pops back the button is either broken or out of place.
If you keep the power button pressed, in 2 seconds you'll see the slide message, but if you keep it pressed, then it just turns off after 2 more seconds. So, yes, it's the power button and nothing else, in your case.
Fix that and you should be back to normal.
And you're not the only one with this problem. Recently, I've tried to help someone else here, with the same problem, as you can see here.
thanks. i called around and a guy here in town said it will take him 30 minutes for $30 to fix it. i'm taking it to him at lunch, so hopefully i'll come back with a fully functional phone--he also was pretty certain it was the power button, and had seen this before. thanks for your help.
well it wasn't the power button. apparently there is a battery connected to the power button that is dying. but you can't even order a new battery, so pretty much once it's dead, it's dead for good and you have to do the camera button workaround like i was doing.
though he did solder the battery to the board a little more (that's another problem, from the factory it is soldered to the main board so even if you could replace it, you'd likely damage the board), and it seemed to fix the problem. he claimed it would only be temporary and within a few weeks the problem will likely come back.

That is weird indeed. I don't think I ever heard of another type of battery being used in phones, tied to buttons. Unless it's a capacitor but anyways...
Thanks for sharing the info with us!
I know this is thread is almost a year old, but unfortunately, it seems my Samsung Focus (v1.3) also has the exact same issue.
The worst bit is that every other aspect of this once glorious phone still works and I was very happy using it, not really feeling the need to upgrade.
I was using a custom ROM which I flashed back to AT&T original 7004 but that did not work. It doesn't seem to be a software issue at all.
The symptoms are the same - tapping the power button to lock the phone gives you the option to slide to power-off and after a second it will do that anyway (without any interaction). When you try to boot, it won't progress past the SAMSUNG screen and in the rare chance it does boot, it will work for an hour or two before dying again. Connecting power helps a little (as you can't turn off the phone with mains power connected), but only just. I have tried using the original battery which I initially suspected was causing issues but even a generic battery has the same issues. I'm tempted to spend $20 on a genuine battery but I don't think it will really help given the generic battery did work properly when the phone was itself.
I'm now faced with upgrading to the Lumia 920 but with new models around the corner I think I'm going for the budget Lumia 520 which has similar specs to the Focus (except LED flash) and will hold out for the new flagship model, or buy the 920 when it falls a bit more.
Hi - just wanted to add my experience with this issue (as my focus exhibited these exact symptoms today). Unlike some people, though, even if my phone managed to boot up, it would shut down again after a few seconds on the tile screen.
Like cysser0, I also suspected the battery at first, but replacing the long-life I had purchased last year with the original battery (which I keep charged as a back-up) had no effect on the symptoms. To be brief, I tried all sorts of things over the course of an hour. Nearing the end of my tether, and resigning myself to try a format as a last resort, I discovered that if I held the power button and the volume button down, I could get the phone to stay on. Releasing either of these buttons would result in the phone switching off suddenly.
Wrapping a rubber band tightly around the top of the phone has allowed me to continue using the phone for the moment, and I have managed to do a backup of all my content (not that I will be able to restore it on this phone, it seems).

HTC HD2 broken

Hi,
After a night in a tent my HTC HD2 started to malfunction. When turning on the device I noticed it said ''safe mode'' (Android NAND (sensation rom)). At first I didn't think much of it, because I thought the device had turned of due to a dead battery. However after leaving it for a while to recharge I noticed that after each reboot it would return to safe mode. Then I noticed that the device kept showing that it was in vibration mode --> the volume down button is stuck(not physically though). Also the device kept popping up ''recent activities''... I'm under the impression that this is due to a malfunctioning call button, not a 100% sure though.
After I reflashed it to wm 6.5 the problem still prevails. However I was able to get a more detailed view of the issue:
The windows button lacks every response, the call button does not respond on touch but seems to randomely activate the call function. The home button functions poorly. However the back button, power on button and volume up button function correctly.
The volume down button seems dependent on the other buttons. When pushing one of the buttons below the screen the volume down button is activated and is stuck untill the screen is turned on and off. However the volume up button does not yield such a result. The volume down button still is responsive to touch though, as long as it is not stuck.
Any ideas how to solve this problem, or how to work around it? As a precaution I put the HD2 in a box with a moisture absorber.
Hi. I wish I could give you a better understand that what I can offer but what I think happened is you probably rolled onto your phone while sleeping.
This is not to say your problem could have came from something else but let me explain a little about safe mode.
Safe mode anyone can enter by pressing volume down and holding it while it boots up. It allows the developer a safe mode they can enter similiar to
why your computer has it installed on it. Normally pulling the battery and letting the phone reboot clears this out though. With that being said i think what
has happened is the volume button has stopped working as it should. There are several sites you can go to here on the web to send your phone out
to have it looked at and fixed. All in all it shouldn't be that costly and if your mechanically inclined and (careful) it shouldn't be to hard to do it yourself. I
would make sure you take very good notes/pictures in dismantling your phone because if you put it back together wrong you can make the problem worse.
Ebay, listing found here has the volume button and the tools necessary to open your phone and repair the volume key for around $7 usd.
Please make sure your phone model is supported and you have the know how to do this without making things a bigger issue. I would also
suggest to wait for more info because I could be wrong as well.
Thanks for your time, effort and information.
However I don't think it is a problem caused due to physical damage to the volume button. In addition the phone was in a 'sidepocket' of the tent, making it virtually impossible to roll onto it. Because the call button is malfunctioning as well I can imagine it being motherboard related, addmittedly I am not much of an electrician .
The issue has been partly resolved. Only one problem still exists. When I push the windows button it results in a volume up response. I performed a hard reset but the problem still persists, any ideas what could cause this?
Cheers
The hd2 high level of integration can not fall. Even without the screen broke, other things will break, so the sets of sets of silicone can not throw. Screen indeed not easy to break unless it fell out just in time to have something to knock to the screen.
