@shose, You can go to recovery?

no, i cant go to recovery
Actually I think it does go to recovery but doesnt show that, because after it "goes to recovert", if I press the volume button it instantly restart the phone (like in recovert - restart the device)
And I dont know how it got this situation. it was lying on the desk overnight (not charching), and on the morning it showed only this static screen
thanks again for all your help!

Now I think that is a hardware problem but for me isn't display error.
I don't know how help you.
Sorry.

thanks anyway
any more suggestions?

I have the same problem. I've been searching around but nobody seems to have a fix. There are 2 or 3 other threads with the same issue here and a few in other places around the net. It happened to me while gps was running and the map software was frozen. I was holding the power button to try to bring it back without popping the battery out when it went to snow and is now permanent.

[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 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!

[Q] NS4G - power button stuck

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?

Mi4 Stucked in Recovery after screen replacement

Hey guys. I'm pretty desperate so i decided to make this thread.
Here is my problem:
I have changed screen on my phone today. Everything went without any problems since I tried to turn on the phone.
When I tried to turn it on I can see only MI logo on display ... Then after couple of seconds phone will restart automatically and goes into Recovery mode.
I tried to boot it from there without any results. Also tried to reset and wipe data without any results.
The biggest problem is that I cant even get into Fastboot menu by pressing Power button + volume down button. So I cant connect my phone with PC and try to flash new ROM.
Any suggestions? I would be really thankful for any advice.
Thank you very much.

Did you follow a tutorial for replacing the screen on your device? Where did you get the screen from? Was your screen replacement just the Touch Panel or the full screen replacement with LCD + Touch Panel? Was it an actual Xiaomi part or an aftermarket part? I would take your device apart again and make sure you didn't leave something loose or disconnected.
Quick question. Was you old display still working where you could see what was going on? Like, was it just cracked or was it completely inoperable?
Sent from my Nexus 6 using XDA-Developers mobile app
Thanks for reply. Yes I followed complete tutorial on youtube. Screen is from ebay. It should be original. I replaced full screen ( lcd + touch panel ).
So found simillar problem as mine - due to improper installation of back cover volume up button was pressed which caused that phone went to recovery menu after start ... ( you have to hold volume up + power key to get to Recovery menu). So I tried to dismantle it again but it didnt help. Still have same problem.
Yes old display is alright. I can see everything just touch screen is broken so I cant do anything on it. But I cant imagine this would be problem of display ....
Give your craftsmanship and handiwork the benefit of the doubt and install your old LCD+Touch Panel and see what happens. If you have everything installed correctly with every cable connected to it proper location then you should be able to boot normally.

Back button not always working

Hi all,
Since the beginning I have a weird issue that my back button sometimes wont work.
If I touch the screen somewhere else the back button works again.
Currently updated to latest firmware for my model 1.27.401.5 and using viper 1.7.0 but problem still exists sometimes.
Any ideas? Or more people who have had this issue?
For me it's the back button and the recent apps button. Started a few weeks ago. Doesn't always happen, but does more often than not. Restarting doesn't fix it.
I presume it's because of either an update or app that I loaded, but don't know what.
hi, same probleme for me back button and led indicator and recent apps button dont work
i full wipe and same dont work plz help me
i tested an othe custom rom and button not work also
it did to me overnight
Help me please

Just out of curiosity, what type of screen protector if any are you using?
I personally don't have a screen protector and I'm also running the latest ViperU Rom....and the only problem I have with both the recent and back button is that they don't have a "wide touch sensitive zone" you have to touch exactly where the button is....which is hard when it's not lit all the time...
I bon t use any screen protector me too

Same problem here. Back button not working sometimes, same with viper, leedroid or stock rom, with screen protector or without.
What version of software do you guys have?
My software number is 1.27.401.5 and now im looking on htc offical page there is an update 1.28.617.6 which is newer than my own, but when i check system update it doesnt offer anything... Sry for bad english

Just started to me. I noticed something smudged on my screen part of it covered the back button. I tried to turn the screen off before wiping it off but every time I tried to wipe it off the screen would activate and the back button capacitive action would keep kicking on. Now I notice neither my back button or right side "menu"button work or light up anymore.
Have only had this phone a few months. This would be a non starter for me. Anyone have any fixes?

Hi,
Have the same problem with my HTC U11 life, both buttons are away. Only the home Button works. How could I fix this problem?
Hello ! I have the same problem with htc u11, the recent application button is working alone, without being touched, lately it's getting more and more often. How can this extremely troublesome issue be solved? Thank you !
Hi, I've had my HTC U11 since launch and it's always had what I would describe as an 'intermittent fault' with the back button. I've just upgraded the software for I think the 3rd time and it's still the same. Now on v 2.33.401.10. I find a little extra pressure usually works but it's annoying, especially when everything else works so well. It's the same whether I have a screen protector on or not and it's not an accuracy thing as I can hit the same spot 20 times and while most will work, there will be patches or 2 or 3 presses where it won't respond. A solution would be much appreciated!
The Back and Apps buttons never worked nicely for me, it was kinda hard to find and press with naked screen and with glass protector almost impossible. However, I have the Glove mode always on and the buttons work fine. In Oreo Settings → Display, gestures & buttons → Glove mode.
But sometimes (I guess when the phone is hot; when charging OR on battery so no charger issue) the squeeze is overly sensitive or there are taps at the top edge of the display when nothing (fingers, metal nor anything else conductive) is nearby the area, in extreme cases it starts pulling down the notification drawer and even opens notifications by itself. It's rare now, if it gets more often, I'll probably claim warranty.
So do I.... I also have the problem with the screen buttons. The "back button" usually works fine and forget to work 1/10 times, however the right "multiwindow button" makes me crazy. Often when I hold the phone in my hand, this button lives with its own life and turn on the multiwindow mode (as it "presses" by itself 2-3 times in a row). At the begining I thought thah mayby I'm pressing it by a part of my palm, but I after observation I realised it goes whithout my contribution. I'm sick and tired.
