[Q] NS4G - power button stuck - Nexus S Q&A, Help & Troubleshooting

Last night I noticed that pressing the power button on my phone no longer did anything. Thinking that maybe the phone had somehow become frozen, I pulled the battery and put it back in. Much to my surprise, the phone came on all by itself without me having to do anything. It seems that somehow the power button got stuck in the "pushed" position even though I can still push it like normal.
I have managed to work around the issues for now thanks to some features of Cyanogenmod (I can now wake the phone up using the volume keys and lock by tapping a widget in the notification area), but I'm wondering what caused this and if it's something that could be easily fixed.
Has anyone else ever experienced something like this or does anyone know how I could go about fixing the issue?

Anyway, someone solve this problem opening the nexus s and manually cleaning the power button. Here a guide to open your device if you want to try:

Opening my ns and cleaning it did the trick for me. Worth a try, your warranty is void now anyway

[Q] Power Button Not Working

Hi guys,
I have a little problem where my phone's power button will not function in any way, long presses, short, almost embedding my thumb in it, all to no avail. This is doubly dissapointing as I have just installed the latest dexter plus patch to fix the problem. I still had the problem on the previous version and I thought a clean start may fix it. The only way I can get the screen on is to press the media play button! Which of course isn't doing anything on dexter.
Hunches:
I have been playing with a light sensor program and using a 3 second press to turn the phone off, I am only thinking this is related as when I re-installed then turned off the phone using a battery pull, that now the media gallery button will now not work at all, so that is a change.
Second, the power button is buggered. Seems unlikely as everthing feels normal, no big drops have occurred from heights, and the button is travelling in and out as usual.
I have also noticed that as soon as I re-insert a battery that the phone starts immediately, the M pops up as if it is already posting. So maybe it is stuck down?? Again, I don't think so, as the mechanism is working per usual.
If anyone can help it would be fantastic, you guys haven't let me down yet, and this thing is purring, but unfortunately I cannot use it lol. Just my luck.
Thanks in advance
another thing, still not solved
Another thing is happening, the phone screen turns on "after" pressing the power button, it may be once or a few times, and then pressing the gallery button.?!?!
Also, at random times it plays a podcast on my phone, the exact same podcast, and from the start, though the duration may be a few seconds then repeat, or it may go for ages, its quite a rude podcast too which has caused me to throw my phone under the car seat to shut it up when people have been trying to talk to me, as you can imagine its quite embarassing.
There are no services or apps running that I can find related to music, it may happen after pressing the camera button, or opening a website.
It is still going really fast though. And I have also reinstalled the light sensor program so I can turn it on and off without causing damage to the power button.
Thanks again everyone.

please clarify
sure, so the only way I can get the screen to turn back on, after turning off as per display power saving preferences, is by pressing the power button, maybe a couple of times, then following that up by pressing the gallery button next to the shutter button, pressing the gallery button doesn't seem to be working to turn the screen on now, but this combo is.
I hope that helped.
Cheers.
EDIT:::
The gallery button alone is working again. sorry guys.
You might just want to reflash it to stock to see if this resolves the problem.
Yeah I think I may have to.
Before I do., I was reading a post on a different forum where another person was having a similar issue. They seemed to solve the problem by using rom manager to boot to a manual restore menu where there was a button tester section, after using it the power button worked for them. I tried but after resetting it displayed a triangle graphic then rebooted.
Is there any way to do this with our open recovery program or any other utility to test the functionality or maybe reset the button or apply a patch etc.
Thanks again :-D

Getting Frustrating
Alright so I followed your advice on your videos on how to reflash to stock, so of course my bootloader does not show up the same as yours on the video. I can get to the bootloader fine, using the button combo or by using quick boot > bootloader, both have the exact same result, the boot loader screens as follows:
Bootloader Fastboot mode
80.89
and that is it....
Also, my computer using rsdlite does not acknowledge the phone, not omap drivers loading etc. Followed your instructions exactly.
This is frustrating me to no end lol.
I am guessing that because I can get to the bootloader with combo no problem, that the buttons physical connections are working.. At least thats a positive.
Can I flash to stock with openrecovery? Or maybe to an earlier version of Dexters froyo? Other ideas?
Any help would be much appreciated guys, trying to use this phone at work with light sensors to turn off screen is not as easy as they say. OMG....
Thanks so much

The fastboot bootloader isn't the right one. So... if you hold volume up + camera shutter while powering on you end up in fastboot? That's really weird.
Maybe your keys have been remapped somehow? Does anyone know a chord to boot fastboot? Perhaps check to see if your USB port is clean?
Lmao
Just my luck to have a weird problem. I thought it may have been remapped so I have been trying the program buttonremap. It doesn't seem to let me do anything except stop the buttons I re assign doing anything :'(
Does anyone have a proper key mapping file that I can replace with my faulty one to hopefully fix it?
Or any other ideas?
Cheers everyone

Ok installed anyunlock it allows you to use any physical button to unlock the screen. It doesn't respond when the Power button is pressed, it responded fine to volume rockers, gallery and shutter though.
Anyone know if this would mean for sure its a physical problem before I crack it open and try and fix it.
Thanks guys.

Breakthrough!
I am pretty sure I have fixed the problem, I tapped the phone fairly hard on its sides and back, and lo and behold after a battery pull and replacement it didn't turn itself on, I waited, nothing, so then I held the power button and it started up!!!!
But....I have another problem that happened before that, I am stuck in the boot animation that open recovery uses before going into its program (i.e. where you can load nandroid, wipe dalvik cache etc).
I was about to load a new rom, and was in open recovery, had installed it and about to do the reset and the phone turned itself off, and thats when I got the problem with the sticking boot animation.
So just to be clear, I am stuck in a boot loop, but not with the M logo, the restore logo.
I hope the power button solution can help someone else, as random as it is.
If anyone could help me get out of this boot loop without flashing stock that would be great. ( i can get to the real bootloader now btw)
Thanks again everyone.
Solved it all
Just took the sd card out and rebooted. And the power is getting better after banging it.
Thanks to all.

So, is your conclusion is that the button was stuck and the banging freed it? It doesn't restick?
The Button is not perfect still. Sometimes over sensitive Occasionally it will not even work but it works most of the time. I am just wondering what cleaning solution I could use to free it some more.
It has certainly been a trying problem. Cheers for the help.
Now I need to figure out why I have this strange ghosting on the top of my screen.....

Samsung Galaxy S2 Power Button Not Working
Hi Guys,
Any solution for the power button problem? Current latest Android 2.3.3 Samsung Galaxy S2 also having the same power button problem. Most of the time I can't use my power button to turn on/off the screen (wake/sleep) and there's no menu for long tap as well. Luckily it does wake when i press the only physical Samsung center button.
What i have already tried: Factory Reset, disable Power Saving Mode, Spare Part+ (apps), Screen Off and Lock (apps), and all won't help.
Is there any current updates or patches to allow the power button to work as usual?
Thank you.
take it to the samsung technical centre
Thats if you still have warranty

Power Button Issue

I have been having odd power button issues since updating to 2.3.4. It is almost like it is getting stuck or something.
Sometimes when I hit the power button to turn off the screen, the screen goes off for half a second then comes back on. This also happens when going from off to on (i.e. flicker on then back off), but it seems rarer.
Sometimes when I hit the home button (and just the home button), it takes a screenshot like I am hitting the button as well even though I am not.
All of this is fixed by just hitting the power button a few times.
Needless to say it is annoying. I thought it might be something mechanical, but I took the case off the back and the issue still occurred. It also seems like the button is clicking then unclicking (i.e. not getting stuck). I had no issues prior to updating to 2.3.4.
Anyone else had this happen or know a fix or workaround?
Yes! I have the same exact problem after the update!!
Glad to see I'm not the only one.
It's very annoying.
My backlight turns on by itself randomly and often if you press the power button to turn the screen off, it goes off then comes back on or flickers on and off. The power button doesnt always turn the screen back on either.
It also gets stuck where I press the home screen and it keeps taking pictures.
HTC better fix this!

I have the exact same problem too since upgrading! I have disabled the screenshot function in build.prop but that only stops the repeated screenshots part of the problem. The main problem with the power button still persists.
I'm having this too, its come and gone to different extents - pretty sure it was happening a bit before the update though.
I'm worried it is mechanical, I couldn't get it to happen with the back cover off but it could have just been coincidence. I can live with having to press the button again every so often but the screenshot thing annoys the hell out of me!
Since the update I've experienced an issue with my power button as well. Sometimes when I hit the button to turn the screen on, nothing happens. At first I thought it was just me but it happens at least a couple of times a day and never happened before the update.
I don't normally turn my screen off by pressing the power button so I can't report on that. Guess I should count my blessing that the screen shot function is not acting up.
Thanks for posting cause was beginning to think it was just me.
FIX!
I found a fix for this, in your build.prop remove the framework line for screen shots and then go in recovery and whipe cache partition twice as well as dalvic twice!
Cheers!

I've just tried this twice but the problem still persists. Sure the screenshot issue is gone but the powering on and off the display is still intermittent.

I was having the same problem with the power button and was thinking it was hardware thanks for the heads up..
am I like the only one without this problem >.< lol. lucky me
I have this same problem too, I believe its connected to the screenshots but i don't know how to turn it off easily (how do I get into build prop?)
This is definitely after the update, I had absolutely no problems with the power button prior to the update.
I don't have any power button isues at all on my European Sensation (2.3.4 still S-On yet). Playing around it just for a week. But the Screenshot thing is a feature not a bug!
Just press <power button> + <Home> to take a screenshot. I like it.
I just starting having this issue yesterday too. Thought it was my power button getting stuck but good to see it's not a hardware problem and hopefully HTC fixes this.

I think you're right. As a test, I used AntTek App Manager to freeze "Scribble" which is also known as com.htc.mysketcher and I haven't had the issue yet. I believe this component is responsible for monitoring for the key combo for taking screenshots. Certainly, after freezing it, the Power+Home combo no longer works for taking screenshots.

I have just tried this but I still have the issue. Sometimes the power button won't wake up the screen and sometimes when I power off the screen it only stays off for a second and then lights up again.
I have this issue too, but I don't think it is software related problem.
It is, as the phone sometimes recognize a power button click as 2 clicks (screen goes off and on).
To see what I mean, go to Recovery and try to navigate through menus - when you're clicking power to enter any menu, sometimes you jump back, as if you were clicking "Go back"...
So, if the issue is even in Recovery mode, so it is not software related. I even restored my stock 2.3.3. soft and the issue is still there. I think it's a mechanical defect

The strange thing is, I even downgraded to 2.3.3 and I still have the problem. I have even flashed stock HBOOT and Recovery but the problem remains. I just don't understand it because it certainly wasn't happening before I upgraded.
Add one more person to the screenshot-club. Haven't had any other problems, but sometimes the phone just keeps taking screenshots when I'm pressing the home key. Extremely annoying, but luckily this is usually solved by tapping the power button. Ofc afterwards you have to clean your gallery of useless pictures... Argh!

I use a rooted sensation and I have experienced that same problem on one ROM. If the problem is really that bad, try going the rooted way.

[Q] Is my power button broken?

Hey guys,
Well, this sucks. Randomly today my power button decided not to do anything anymore. I've done some googling, and found people who have some problems unlocking with it, but i can't even use it to lock my phone.
For now, I can use the phone by letting it autolock, and unlocking by double tapping the screen, but obviously this is not something I will be able to keep on doing.
My main problem is, I wanna try the good old haaaveyoutriedturningitoffandonagain, but the only way to shut it off is probably to just let the battery run out.. And then I'm scared that I won't be able to turn it back on again
Is this a known issue? Or is it probably just random hardware failure. Can any of you wizards help me out?
Thanks a lot in advance!
well that's odd never heard anything like this before...did you try to use your power button when you r not in OS...for instance try to go to recovery using volume- and power....or fastboot by volume + and power...

Power button / Screen Wake Suddenly don't work

Hey guys,
strange and frustrating problem. I was using my phone pretty extensively today (although nothing crazy), mostly thanks to Pokemon Go. Tonight after using my phone normally, I went to press the power button to turn the screen off and nothing happened. I was able to reboot (by changing one of the long-press actions to bring up the power menu via GravityBox) and then was unable to power on the phone. It seems like my hardware power button has suddenly become unresponsive. This leaves me unable to power on/off the phone, including booting into the bootloader. Also, I seem to be unable to wake my phone up by double tapping the screen or swiping up.
The phone otherwise functions fine. If I get a notification, the screen wakes up and I can use the phone. Otherwise, the only way I've been able to get into the phone is by connecting it to a computer and issuing ADB commands. The IR blaster functions fine which makes me think it's not the hardware button?
Has this happened to anyone else before? Can the power button just break like that without any water / physical damage? The fact that I also can't wake the screen makes me think it's a software issue. One other thing I suspect is that my phone abruptly died yesterday (battery died despite software thinking it still had juice left). In the past, with the modified kernel / rom, this has resulted in some nasty issues, including 4G not working and the Android system process basically exploding. I thought I lucked out when I powered it on after that, but maybe it just took a day for this issue to manifest itself.
I'm going to make a NANDROID backup and try flashing a few different things to see if I can fix it. I'll post my progress here.
Current build:
- Verizon M8, S-OFF
- TWRP
- Android GPE 6.0 (MRA58K.H13)
Edit: I haven't been able to find a fix. I'm a bit afraid to try a full RUU since I can't use the hardware keys to reboot into the bootloader should something go wrong. It may just be that my PWR hardware button is f'd which really sucks. I'm not sure I'm up to cracking open the phone to fix it. In the meantime I downloaded an app called Gravity Screen On/Off which uses the phone's proximity sensor to wake the screen up and it seems to work ok for now.

Nexus 5 - Sleep of Death? Once going to deep sleep, phone dies.

Hi there,
I have been struggling with a problem the last few days, and have been reading quiet a lot. I got two old Nexus 5 phones, one had a broken screen, the other one had the display glitching problem - related to the flex cable. So I opened them and put a working one together out of both.
So far so good, everything seems to be working, with one exception: Once I press the power button, the screen goes black like its supposed to. If I wait long enough and try to wake the phone, its not responding. The only thing that helps is long-pressing the power button to hard reboot it.
So I did read a lot, about the power button malfunctioning and the batteries dying on the Nexus 5. I ruled out the power button problem and its working like it should. I ordered a new battery, which is not perfect, but has an estimated of 1800 mAh. I monitored the voltage of the battery with different apps, even logging them to see what happens right before the shutdown - but everything seems normal. So this could not be the problem either.
I am currently running the latest LineageOS, but I experienced the same problem running the latest factory image google released for the phone. I even tried different kernels. So I thought, it might not be software related. But since it always happened when the phone starts to enter the deep sleep , I tried to google some about this and found the SOD ( Sleep of Death ) problem for the Nexus 4. Since I was out of ideas, I installed an App called "SOD Killer", which creates a wake lock preventing the device from sleeping. Et voila - the problem is gone.
I could not find discussion on the internet relating to the nexus 5 concerning the sleep mode and the phone dying once it goes to sleep. Am I missing something here? The SOD Killer wake lock solution is a good temporary fix, but I would like to get to the grounds of this.
Does anyone have an idea what could be causing this strange behavior? Thank you in advance,
joha
What I forgot to mention is that once the phone is connected to a power source, the problem does not appear. That is also the reason why I wont get any logs via adb. ;p
I will try to get some logs with an APP and root once I get home - maybe there is some information about the problem causing this strange behavior.
I managed to get a log while the phone died when it wanted to activate sleep mode. But I am not that good in figuring out what in the log might be pointing in the direction of the failure. Any ideas?
I dont like the
Code:
09-21 12:11:51.977 E/BatteryStatsService( 786): no controller energy info supplied
parts in there. What might be the problem here?
Thank you so much in advance!
Does no one have any idea? I guess its hardware related somehow, when the phone tries to enter deep sleep. Anybody out there that knows, what the phone is actually doing when entering deep sleep which might be causing it to die / become unresponsive? Any idea is highly appreciated - I love that phone.
