[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

Just checked my system / user / keylayout folder. How many files are supposed to be inside, there are a few. I checked the contents of some and they seemed to be the same. Just an idea.... thanks again.

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.

No one has any solutions for me? Come on 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

Strange incident with CWM

hello, yesterday i was changing rooms and i was wiping everything trough cwm 5.0.2.3 carebear.jrodd.
After wiping i went to choose zip and then i was sent back to main menu, i could choose any option from main menu, but behind options was waiting for me, tiny android fella with open box and some sort of a arrow sign.
I tried at least 15 times to get past that android fella and his freaking box with arrow jumping out of it , but i could not.
i could use nexus s soft buttons and at the bottom of screen was message saying "back button disabled".
i had to remove battery{ i didnt know what to do/i didnt actually have any other options, that i knew about}, then i powered back in to CWM and flashed rom.
everything works fine since then.
did any of u knows what happened?
i flashed lots of roms and i always trying to do everything up to code, but something like this happened to me for the first time.
it wasnt the most pleasant expierence

the same thing happened to me once on my ns4g. I had to pull the battery.

try flash recovery img at fastboot and then see if you can get in recovery

As long as it is working OK now then all is good.
Happens every now and again.

Ok this has happened to me a couple of times and from what i have found if i press both up and down volume buttons and power button in random combos after about second or third try it sorts it self out. I have tried to create the error and from what i have seen its if you are a lil heavy handed and either press the volume up and down together to start with or the power with one of the others at the same time it does some weird lock on going back or rebooting or anything really. don't think its isolated to the version of CW as i've had it on older builds

It's caused by scrolling through the menu options 3 times. It's actually a feature. I forget where I read it but apparently back in the day there was a dude with a broken power button who couldn't select things in CWM so Koush put in that feature just for him. I believe one of the other buttons works to select items when that's enabled. To get out of it just keep scrolling up or down through the menu options 3 more times.

You ended up in the stock recovery. Hold power then press volume down OR volume up (cant remember which) and you'll be in stock recovery.
Also, the physical buttons are disabled when you press vol up and vol down at the same time. Do it again to return to normal.

happened to my yesterday again, after six months of problems free.
anyway nothing to be scared about.
thank u for answers, i kinda forgot about that thread... LOL

Camera app opens when unlocking my S6

Hi Guys!
My camera app opens when i unlock my phone. This happens randomly, anybody with the same problem? If yes, any solution? It's very annoying.

Maybe you're accidently hitting the home button twice everytime you unlock it.

No, i'm not accidently hitting the home button because i have turn the feauture off in the settings. This morning it happend two times already! Nobody having this problem?

Did it do this with the feature turned on? What happens when you unlock the screen using the power button or the wave gesture?

Yes, i have done it with the feature turnd on also and tried with power button and gestures but still have the problem. I have noticed something weird, when i lock the phone after like one second it turns on and then when i unlock it it goes to the camera app. Something triggers the camera app and i know it's not me. I have flashed the stock rom and rooted the phone and still have this problem! This is very frustrating! I dont know what else to do

Do you have any apps that might have triggered this behaviour. It's almost always a dogy app triggering it. Just a thought.

No, nothing that can be related to the camera. I dont have a lot of apps installed on my phone so it can't be that. It's indeed a very strange behaviour.

I have a similar problem. When I unlock the phone sometimes the camera will open. Sometimes dialer , messages, gallery, browser all kind of apps will open by it self. Normally happens with the finger print security turned on. Will try using notmal lock screen to see if it still happens

Just checking. You know if you swipe upd into the middle from the right bottom corner from the lock screen. It automatically unlocks to camera.
Does it happen when you swipe horizontally?

Keyboard no longer working properly.

Today my keyboard decided to no longer use the I key in default view. This is odd because calibrating the keyboard allowed me to use the I key. After calibration finished, it went back to no longer working. I've cleaned my screen protector, and when pressing I, it "clicks" both the u and o key at the same time. This not only affects the keyboard, but in some other instances will not allow me to click a small icon, such as setting in the drop down menu. I've since done a factory reset and even flashed a new rom to no avail. The only possibility is there is a small half bubble at the top edge near the camera, and will have ghost armour replace it if I cannot find a cause as to why this happened. Any suggestions as what I could try?

It's a long shot, I don't know how often you update through GooglePlay, or if you even do... I do know that a version of webview made my phone do the same thing, it had dead spots on the screen but only when my keyboard was up in default SMS. I had the same the problems as you, buttons on the other side of the keyboard were being pressed & it was selecting drop down menus to save the text above, copy, etc... I found out the version of webview I had was bad, I know you did a factory reset, but maybe it restored the same the bad version?!?!? Try updating it if possible, or uninstalling updates for that app. It may just work....

Unfortunately it didn't work. In installed updates and tried freezing with tibu. To no avail. Called HTC and all they want to do is me sending phone in for repair. I don't like this option

What carrier do you have the phone through if any at all??

Yeah, sorry about that, i wouldn't be happy about that either. I was wondering if you had a phone carrier, if so which one. It seems as though you didn't buy it through them since you are in contact with HTC. I know HTC warranties your phone up to a year, but they should send a replacement in the meantime if you have to send it in Good Luck, sorry I couldn't be more help. If you have a phone carrier that you purchased it through such as Verizon, they would replace it right away as they have done for me about twice now:good:

Long press problem with my s8+ only in the center of the screen.

Hello.
Since a long time i have a big issue with my rooted s8+.
When i want to long press (tap and hold) on my screen to select a text, sometime it works sometime it doesn't work (it do like i pressed the screen and releases it immediately when it does not work as short press).
Until a few days ago i thought it was a random problem.
But i discovered a few days ago that this problem happens ALL THE TIME when i need to long press on the center of the screen and NEVER HAPPENS when i long press on the top or bottom of the screen.
Now when i want to select a text in the center of the screen, i just have to scroll the text up or down and then the long press works.
Does anybody have the same issue on his s8+?
Is there an app to definitly check this issue that happens only on long press and never on short press ?
How can i fix it?
Thank you for your help
(sorry my english is very bad i hope you have understood my question)

Open up your phone app as if you're going to call someone and dial *#0*#
(Star pound zero star pound)
This will get you into maintenance mode where you can trouble shoot many things. Tap on "touch" and drag finger all over the boxes on the screen in the shape of a rectangle with an X through it. This will allow u to see how your phone is responding to touch. Hope this gives u an idea as to where or if the issue is occurring. If not at least it's a pointer for phone issue trouble shooting.
Cheers!

Thank you for your answer.
I tried that and everything is ok on the touch test.
But after this test i just tried to select something on this page and i have the same issue. When i want to select in the center of the screen the tap and hold is not working.
I scroll a little the page and it is working.
It seem it just don't detect that i hold my finger. But detect normally when i just press with my finger.
I think i should send my phone to Samsung.

When i try a tap and hold (i tried several times) on the line "i scroll a little the page..." it does not work ( it just select the word on which i have put my finger but i can not extend the selection and i don't have the icon with copy past etc)
But when i tap and hold on the line starting by "of the screen the tap...." and the line starting with "it seem i just don't detect..." everything is normal.

Here's your troubleshooting steps. Try them each one at a time. If #1 doesn't work, then move on to #2, etc, until it's fixed.
1. Reboot phone
2. Clear cache in recovery
3. Start in Safe Mode
4. Factory Reset
5. Reflash stock, factory firmware with ODIN
If none of those fix the issue, then you will need to reach out to Samsung.

I think most that it would be a hardware problem
But as my phone is rooted i will do all that before sending to samsung as i must install a stock rom before sending to Samsung.

The steps I gave you actually eliminate it being a software problem, so it narrows it down to hardware.
Let us know if you're able to fix it, or have to send it to Samsung fie repair.

I just updated my samsung firmware on dec 28. And i had this issue before the update.
When updating, for the root, i installed twrp and have done a complete wipe on twrp before installing magisk. (i still didn't find no way to root without wiping, if there is a way please tell me)
I think i have passed all these steps when i have done the update/root process. Am i right?

I honestly don't know. I don't root. So I don't know the steps. Try them anyway, and if you end up having to do a factory reset, don't restore anything. Start completely fresh.
And installing STOCK UNROOTED firmware with ODIN will eliminate any issues associated with root.

Did you try doing a factory reset? You could try that but it sounds as if it is a hardware issue. Get it in to samsung before warranty runs out. Good luck my friend!
