Tmobile SG S2 Software problem or power button

MY galaxy s2 has problems with powering off every now and then. it was really bad at one point where all it was doing is turning on and rebooting right after. i had a custom rom for months and never had problems until yesterday. i couldnt go on recovery mode because it would always restart every five seconds. Now it seems to less frequent because i realized that it always reboots when i touch the power button once. Sometimes when i push the power button to take it off sleep mode, the power options pops up (recovery, restart, power off etc) so thats when i thought the power button might be the problem
Any guesses on what could be the problem?? If its software problems or power button issue.
P.S. reset my phone, re rooted it, and put a new rom darkside. It literally stays on until i push the power button. then it restarts five seconds later.

the power buttons seems to stick....I have the same problem, the phone is acting as if the power button is being pressed without being let go. When the power button is held indefinitely it just keeps rebooting over and over again. It occurs sporadically, but once it sticks..it sticks. I seem to be able to unstick it by slapping it against my hand but eventually it turns off. Its definitely a hardware issue and I will open up the phone right now to investigate. Ill write if I find anything useful.

Major Catch 22 - Desire got Wet now have 3 issues! PLEASE HELP

Hi guys.
So i managed to get my desire wet/damp and whilst it still works it has developed 3 issues:
1) The weirdest of all - the phone wont go into standby, as soon as you press the power button or let it timeout the screen goes off and they instantly turns back on to the lock screen. If i leave it, it will timeout again on lockscreen and come back on, it does this forever. I have done factory resets etc, all the same. Weird right. As i result i would like to reflash the mod and see if that fixed it as assuming its software related (somehow).
2) Volume keys do not work - think means i had issues getting into recovery. Finally found a widget to do it and then....
3) Trackpad does not work in recovery so i cannot re-flash or try any new rom to see if that fixed (1)
Proper catch 22
Any suggestions appreciated.
Thanks

Install 4ext touch recovery.

Update after installing touch recovery
OK I HAVE AN UPDATE:
The plot thickens but i have managed to S-OFF my Desire and eventually install Clockworkmod Touch which obviously doesn't require me to use the trackpad button so I was able to use Recovery. I wiped the phone and tried reflashing the ROM i had been using (Insertcoin) but this made no difference, the phone still keeps waking up immediately that it goes to sleep (either with power button or by sleeping timeout).
So i decided to install a completely different ROM (CM10_VJ_4.1.2_v3.0) and this installed fine. Now the phone will go to sleep and stay asleep if I press the power button. Problem solved I thought!
Now when the phone is asleep 50% of the time, trying to wake it with the power button will cause it to reset immediately and goto the white HTC screen. When it restarted it sits on the unlock screen and keeps timing out, screen goes off, then immediately on again - weird. If i unlock and lock with power button it will behave. For some reason the Search key will wake the phone every time no issues. Only the power key to unlock causes it to reset. Phone is sleeping according to Battery info.
Any other suggestions for what I could try. Could this possibly be something hardware related now? If there a way i can log the key presses or reason it wakes/resets?
Any help really appreciated, the phone is pretty unusable with this reset issue now.
THanks

theres a few videos on youtube, if it was me i would take the phone apart and clean all round the buttons. mite solve it. But as it got wet, the water could of damaged something in around the trackpad r power button, hense always waking the phone.

Thanks mate. So i tried this and installed CM7 today and have discovered something. As i said above the volume down button doesn't work and the volume up only works with some persuasion. Once i installed CM7 the problem where I lock phone with power key and it instantly wakes up now persists (on the JB rom it at least stayed asleep but reset if power button was pressed again).
However whe i changed the display timeout to 15seconds i watched as it timed out and instantly woke then noticed the volume would increment down one notch each it woke up again. This leads me to think that rather then the volume down not working at all it is actually stuck down permanently and could be causing the issue here. Is there any way I can find out if this is the case and disable the volume keys through software or do i need to open up the phone and disconnect it?
Thanks for any help - i think we are getting there!
Bridgstfer

I actually worked out that the trackpad is being pressed down constantly too because on CM7 when i disable trackpad to wake the phone actually stays asleep. Stil the phone resets if i try to wake with power button though, must be something to do with the button combo being held down.
Is there any way to disable both volume and trackpad buttons at the kernal/system level?
Tried button remapper but does not allow to remap the trackpad press.

With a file explorer, go to
system>usr>keylayout and modify bravo-keypad.kl.

I'm just back from holiday where my Desire had a ten-minute swim in sea water!
Naturally it was stone dead when I remembered it was in my pocket as I waded across an inlet which was supposed to be ankle- deep but was over 1.5 metres in places
I thought there was no point in drying it out without first removing all salt so (minus battery and cards) held it under a tap for several minutes then left it to soak in tap water in the sink for 30 minutes.
I then dried it over gentle heat for a few days then tried the battery. The vibrator ran continually and the white LED flashed randomly but nothing else. After another two days drying it booted - but only into Fastboot and the vol switch didn't move the cursor. But after another two days - it worked almost perfectly! The vibrator is dead and the screen a bit streaky, but all the other sensors work just fine and it's quite useable.
I had been logging the hike using My Tracks and it actually shows the course going a short way into the sea.

do you have an assurance or warranty?
if yes-->change phone.

Thanks for this. I actually got an app that let you remap the keys but it does not let you do anything to the trackpad click button (which is now the one stuck down). See photo of whats in my bravo-keypad.kl file here:

Any other way i can disable the trackpad completely. Perhaps at the kernel level?
Thanks

[Q] Power Button messed up

The power button on my S3 (SGH-i747) is pretty messed up. When i'm not touching it, it decides to register a press and completely messes up everything im doing on the phone. It has such frequent reboots that i can barely boot into recovery. The only way i can actually boot is by holding the phone horizontally with the power button facing down. Is there any fix to this? I'm on CM10.1.0 so would flashing back to stock decrease the sensitivity of this button? Or is it necessary to fix at the shop?
Also i have a cracked screen, so im not sure it would be accepted under the warranty even if it's unrooted.

Hardware failure, repair it or get a new phone
nothing you can do, the flex cable that connect's the button to the board is either busted or shorted

I'm having the same issue.
There's absolutely nothing I can do? I thought maybe if I'd open up the device and tinker with it... maybe I can get it working.

Yes this is quite an annoying problem. If you're having the same problem, are you able to boot into download mode? I can't for some reason.

Something like this you don't want to boot into download mode. What if it resets while you're pushing a file? then your whole phone will be messed up.
I got mine to boot. My method is a bit unorthodox though.... i kept pressing the power button throughout the boot process up until the lock screen. Once it finally loads... i flicked the power button a few times really hard.... it seems to stay in the position but remains extremely sensitive.. as in, i dont even have to press it to turn off the screen.
sucks man... i think this is happening to a lot of power users. I'm literally one week past my warranty.

Yeah i didnt want anything to happen while anything is installing etc. I somehow got into recovery, but it shut down within a second. (thankfully the first option in cwm is reboot, so that saved me). I can't return for warranty because I'm rooted on CM10.1.0, which was why i wanted to attempt unrooting (but that seems impossible at the moment).
http://forum.xda-developers.com/showthread.php?t=1753574
That thread seems to be the solution to our problem, but i feel that if i open it up, something worse will happen. Right now, the phone boots up fine when held horizontally (but shuts down ~2min later) and i can easily backup my data.
One strange thing that i've noticed with this problem that maybe isn't right. Normally , do you have to hold down the power button to shut it off? I always used to think that a power menu would show, THEN you could select shut down, but here, it just shuts down. The power menu flashes sometimes, but shuts down anyway. This may also have me believe that something other than the power button is the problem.

if you hold the power button for 5 seconds or more , it will skip that power menu and reboot. So this still sounds like power button to me.
thanks for the link, been searching everywhere... so fckin hard to search all the S3 threads on XDA. They need to consolidate

Were you able to fix your problem with the fix in that link? I seem to be having the same problem as you.

No, I ended up buying a new phone (I was going to upgrade anyway). I took out the power button, but that wasn't the problem. In a way, it was the button under the button that was sensitive. I would have to take out the motherboard to see the exact problem.

[Q] Sumsung Galaxy Tab S 10.5 (SM-T805) screen went black

My tablet Galaxy Tab S 10.5 (SM-T805) screen went black. I can’t see the screen.
Touch also does not seem to work. However it’s on. it is receiving calls and other messages. It is connected to WiFi.
Power button, volume button are working but I can’t power off the device cause I can’t see the screen options.
When I plug in to the charging cable it vibrates but does not show anything on screen.
It didn’t drop and hit by anything…i have been using it for 3 months now. it just happened by itself or may be by some update that I don’t know.
Please help how to bring it back to life

Are you able to get into download or recovery? I've never heard of something like this before. Maybe go ahead and let it die and then plug it back in and see if you can get into download mode by holding home+power+volume down then re flash your stock firmware or whatever you were using. Or do home+power+volume up to get into recovery. If you still have stock recovery then you can just do a factory reset right from that but if your using something TWRP then your still going to need to flash something after wiping your data.
Not sure how else you can get it to shut off since you can't see it. Even knowing where the power menu is once you press the button it would still be tough to hit the right thing. I'd say let it die. Maybe someone else can come shed some light. Of course it could be a hardware problem as well. I'm leaning toward software still though.
If your still completely stock I'd say let it die and get into stock recovery. Home+power+volume up and then wipe data and do a factory reset. Now if the screen stays black after its off and you've plugged in the charging cable then I'd imagine there's a more a serious problem going on.

Yes I am waiting for battery to be completely drained out. I will try your method once the battery is completely dead.
thanks

Your welcome let me know how it goes. Will do my best to help.

I don't have my tab with me right now but can't you hold power button for 10 sec to force a reboot? All Android device I ever had could do that.

Doest work on t805 holding powerbutton, just hold the buttons for download mode and that will force it to reset and prompt you to press volume down to cancel volume up to continue...hold for 30 seconds, and if nothing appears let go and just press volume up once, still no joy then pop back cover off and unclip and reclip battery if your brave, thats what i did before i new about this quicker way.

How to run the battery completely down..? its still active and on... though not showing anything on screen.
Is there any quicker way... ?

To do a hard-reset on these Samsung devices, you need to hold Power + Home + Volume Down until it reboots. On every other device it's just Power. Some it's Power+Home. For some reason Samsung likes to be different.
Or if you have previously enabled USB Debugging, you can plug it in to your computer and do an ADB Reboot.

Power + volume down + volume up works for me as reset.

Holy crap the dude is right....just tried that myself on t805, holding all 3 buttons at same time in top left corner power,vol dwn, vol, up forces a simple reset without dwnload mode rubbish.

[Q] Display and touch screen major issues following lollipop update.

Problems with my Samsung Galaxy Tab S 8.4 SM-T705:
1st: October 2014
2 weeks after buying, my tablet's battery drained overnight from 45% to zero. Next morning, I turned my tab on after charging to find out that the Tab starts but without any Samsung GAlaxy Tab S logo or Samsung Logo and the Screen has turned green, rendering it difficult to read in auto brightness mode or low brightness mode.
I restarted the device 2-3times and the device started working normally. This was my 1st device restart. I never used to power off the device before.
In 1st 6months, this greenish display problem n logo problem occured 2-3times, and i ignored it, because, it used to get resolved by itself with restart and I had no service centre in and around 50km to my work place.
2nd: January 2014
My device all of a sudden stopped working.. actually hanged.. I managed to turn it off but failed to restart it.
Later I realised that the device has restarted, but the screen was not responding when the screen blinked for a moment with the opening of book cover.. and the back cover of device was warm..
Googling taught me the way to access recovery screen n I opened recovery mode with "power+vol down+home key" and pressing vol down in recovery screen to restart tab.. again the tab started working fine..
3rd: Lollipop update: May 2015
I did Lollipop update. The device was smooth to operate at first. But gradually, i noticed that unlocking the tab failed to light up the display everytime, just the soft keys lighted up. But one day, the device freezed with no response from touch screen. I was unable to switch off the device also.. I had to drain the battery by playing music using S voice to turn the device off. "power+vol down+home key" too was not working.
On googling, I learned to reset device with "power+vol up+vol down" keys pressed together. finally the device restarted, but the device used to hang occassionally.
Googling let me know that i need to factory reset device upon firmware update for normal functioning, which i didn't do after update. so, I backed up my device, uninstalled many apps to make the device run a bit smooth and did a factory reset.. Resetting didn't improve the situation much, but now, the device display failed to light up on a regular basis on unlocking most of the time..
Now the situation is that, the device turns on, finger print scanner works, all apps n everything working, but display remains black, and touch screen is not responding.. using sidesync, everything on Tab can be accessed via laptop.
Tricks tried:
1) Factory reset
2) power+ vol up+vol down
3) power+ vol up+home key
4) power+ vol down + home key
5) Power off using sidesync and then restart
Results: All failure. Everything works but the display never lights up normally..
Plzz help....:crying::crying:

Bump. I'm starting to have similar problems with my SM-T800 running 5.0.2. I open the cover and the device fails to turn on. I press the power button and the screen stays black but the notification bar turns on. I can shake the crap out of the device and the screen stays black but I can see the notification bar flicker. Driving me batty.

If i had any problems like you guys, I would just return it to the place i bought it, for a refund or replacement or even a repair, post it to the service centre if it`s too far to travel too.
You problems sound like battery and or loose connector inside your tablet, it happens frequently on Samsung tablet for the connectors to come loose, if the tablet is dropped or twisted, no outside damage might be seen.
