[Q] Phone turning itself off and on. Continuous never-ending cycle. - Android Q&A, Help & Troubleshooting

My phone is acting really strange. It turns itself off and then on again and again in this cycle as if the power button is always being pressed.
I can sometimes get into my recovery (CWM) but when I try to go deeper into the menu. I get kicked back to the main screen as if im pressing the power button to go "back" until the phone gets completely turned off again.
I noticed something too. When I pull out the battery and put it back on. The phone turns itself on without me even pressing the power button. Then the cycle continues again.
Very frustrating.
Could this be software, ROM, recovery, partition related or does this sound something hardware related?

if you are on stock rom backup first then factory reset if problem still. unroot your device be in stock rom then go to service center because you can change hardware buttons even if you rooted

Is it possible to backup, unroot and return to stock if i cant turn on my phone?

Quick update in case someone bumps into the same problem.
I just got back from the repair shop. The power switch was indeed broken. The technician replaced it with a new one and the phone works fine one.

[Q] Screen not working out of the box

Hi,
i recently bought 2 Galaxy S wifi 5.0 as there was a deal going. first one worked fine but a few days later and i've opened up the second one to find the screen isnt working.
its stuck at the 'select locale' screen from the initial setup with me unable to scroll and select any options. the back and menu keys don't work either although the home button seems to be doing something as the keys light up when pressed and it also works in recovery mode.
The volume key works as i can see the media volume going up and down when its pressed, it also worked when i booted into recovery mode to try a factory reset.
i can see the media scanning running after bootup and when i plug in the usb to a computer it appears with the USB connected (but ofc i cant press the button) so i think the system is running fine?
the power button seems a bit stickier than the one thats working fine and also when i hold the power button in to shut down the device (unable to press power off) it comes straight back on. is there way to force a shutdown rather than reboot?
just wandering if theres anything i can do to hard reset? im a bit reluctant to flash a stock rom / gingerbread as i have on the other one if the screen is just dead but thought id see if anyone had any ideas of anything i can try?
cheers,
Well, I would return it since it is still under 30 days (where did you get it?).
comet was £99.
yeh ill probs take it in tomorrow just wandered if there was anything i could do to double check the screen was definitely goosed

[Q] Weird volume button issues with my x2

Last night I pulled my phone out of my pocket to answer a text, as soon as I unlocked it, the volume bar popped up, went from full volume to silent/vibrate and continued vibrating. I tried to do anything but volume down kept interrupting everything. Even opening random programs and what not. I pulled the batt and restarted, it sat at the droid screen with the white "rsd service loading" or whatever it is, and sat there for the rest of the night until the battery died.
I got it to start up and boot all the way into the OS. It acts normally until i press the back button or the volume buttons. It then goes into the haywire crazy vibrating mode. I can get it to stop sometimes by pressing the Home button. But as I type this its randomly vibrating on my desk.
You fellas think this is a hardware issue or software?
P.S. I tried getting into the boot menu and clearing the cache, but pressing the volume button just caused it to hang at the rsd load.
Ur not on cm7 huh? Our bootstrap is automatic on plug in while power off.
Cyanogenmod
No sir. All stock, no root. 2.3.4
I was rooted before, but had all sorts of lag problems. After going back to factory everything seemed to clear up. So thats where I've stayed.
I'm considering just using my insurance and getting a new one (hopefully an upgrade to a 3 or something) as my case is fairly worn.... But if I dont need to..........

[Q] i777 Power button broken - Stuck in Recovery

Pretty sure I overheated the phone last night, and now the power button doesn't work. I fell asleep with it in my pocket, I got a call from my wife early in the AM, after the call I found the screen wouldn't turn off. So today, I've tried an app or two to replace the power button, tried a 3 hour battery pull, and in a brief instance of idiocy, decided to reboot into recovery to try and wipe everything and see if that would do anything - now I am stuck in CWM Recovery w/out any working power button so I cannot even exit. I've tried pulling the battery again and it just reboots into recovery.
Any tips on how to get it out? I want to pull my pictures and info, wipe the phone then sell it on ebay - What would I need to do?
if it is a custom recovery you can use ADB while booted into recovery.
adb pull /sdcard
Has anyone had a problem with just the power button not working at all anymore?
My SII had the problem recently that the power button just does not work, so I can no longer wake the phone up after the screen has shut off. I'm guessing it is a hardware problem because I even restored it all the way back to stock.
Does anyone know how hard it is to replace the button if it is bad?
I had my power button fail for several days on me (it has since started workign fine again tho). I was in a similar place but when pulling battery, my phone would reboot normally so i could at least use my phone while on the charger. I know that pulling battery, holding volume up/down and reinserting will boot you into recovery so i'm wondering if your volume button is messed up too? can you navigate up and down in recovery with the volume keys?
I had to get my button working to position myself to avoid the issue but I'm now pretty much power button free and running siyah kernel (touch recovery) and i use the Stweaks swipe to unlock feature, rootbox rom with a power menu toggle, and a lock screen widget so i don't have to use my power button at all. Again, i had to get my power button working to flash the kernel though maybe you can push the kernel with odin then you'll have the touch recovery to try wipes and resets with?
edit: here is a link of tearing down a 9100. I think our power button is the same- unfortunately it looks like you have to solder the new one in.
I couldn't find the part# for the i777 (or confirm if it's the same as the 9100) but the power button for the 9100 is KEY FPCB-POWER KEY(GT_9100) GH59-10916A and is about $5 online
here's a vid of the breakdown, he's replacing the screen but browses over the power/volume keys too.

[Q] S3 keeps restart itself

i got s3, suddenly it started to reboot itself all the time, what i see is only the samsung logo and then black, and samsung again.
the funny thing is that when i put the battery in, it automaticly start with this loop.
during the loop, when i press home+volume up, i can see the cwm screen for two seconds, and then it reboot again.
if i press home+voulume down, i see the warning in the stock recovery, but when i press volume up, nothing changed, and eventually after two seconds it reboots again.
i tried to connect it to my pc, but it dosen't show it in device manager, and have no indication that i connected it.
also, when i connect it the charger, i see circle, and then a battery for a brief second, and then the circle again.
is it simple hardware problem (stuck power button? even though it seem okay, but it may explain the automatic turn on), or half SDS?
anyway, are there any recommondations? i have'nt flashed it recently or anything like it.

as i wrote before, i can enter to both recovery modes (volume up or volume down) for something like two seconds, i can't do anything in it.
if i try to get to download mode (home and volume down) i see the warning, but either i press volume up or down, it reset itself.

the regular, about flashing custom roms, if i want to continue press volume up, restart, volume down.
either way, it restarts.
any way it is the power button stuck in 1 mode?
If phone starts on battery insertion, before you push the button then yes, power button is shorted out.

Try leaving the battery out overnight/long time, it helped when I got my phone stuck in a bootloop. But that was due to oc/uv...did you try something risky, causing it to bootloop?
no, it was in regular use, nothing risky.
yesterday i dissassembled it and checked with multimeter, it seem that the power button shorting the circuit, so i ordered a new one, going to be a surgical operation...

[Q] Power button, interesting/puzzling problem

So the power button on my GS3 is fried. (I am pretty sure at least)
Anyways at this point that is not really the problem. So a few hours ago I was able to boot my phone back up without the power button by taking the battery out and putting it back in. However, silly me wanted to boot into recovery to try something, but now my phone won't even boot. When I take the battery out and put it back in, it boots to the screen where it says "booting recovery" on the top left and then stops working. If I try to go into download mode, it shows the screen asking me if I want to go into download mode and regardless of if i press volume up or volume down the phone stops working.
I'm hoping there is some nifty work around for this. Should be fun Thank you in advance!
EDIT: In short, I am looking for a way to cancel booting into recovery.
Sounds like you will have to replace the power button before you get to see if the emmc chip is corrupt. Unplanned shut down can corrupt the partition being written: system, data or recovery.
