[Q] Power Button Tripping Out

Howdy,
Got a weird issue on my desire - basically the power button keeps registering a press even when I'm not touching it. Fault seems to come and go a little, it'll happen for a day but then stop doing it for a couple of weeks.
It's definitely not rom related since it'll happen inside recovery - it'll even turn on the phone if i've shut it down.
Just wondering if anyone has had this, whether it's an expensive fix etc... any info would be great!
Cheers,
Matt

[Q] Any way to disable the power button?

Hey guys,
So I've got an S3 running AOKP at the moment and I was wondering if there was any way to disable the power button. It's been malfunctioning, and causing my phone to reboot constantly. Sometimes even when off it continues to think I'm holding down the power button and cancels the boot process...
Any ideas of a workaround? I'm out of warranty and can't want to pay for repairs at the moment.

Hi,
I am having the exact same issue. Very strange as it decided to do this while checking my email (finger no where near the power button) and I have never had any issues prior to this.
I'm running CWM, CM10.2 and I CANNOT BOOT into recovery (CWM) or ODIN, best I got was the CM loader screen then it reboots.
Even if I disconnect the battery, wait 30 minutes (fully charged) and replace the battery, it attempts to boot itself again. and again and again...
The best videos I've seen involve smacking the phone on the power button side (not going to do that, at least hard) I think it may be a random power button failure. I will be disassembling the phone tonight and trying to open or close the power button contacts and wipe my phone before it goes back....
Yoiks!

It's very random for me too. Sometimes it'll work all day then it'll take like an hour and a half to turn back on.
Quick question, as I've heard this from a couple people. Do you use an otter box?
Regardless I'm 90% sure this is hardware related and has nothign to do with software, because all the cases I've heard of this have had different roms, one of which was stock unrooted.
Pretty frustrating. Not sure I'll buy a Samsung again to be honest.

This started gradually happening to me too and I bought both my phone and Otterbox in July 2012 when it came out. I noticed with my family members' S3's that their Otterboxes were different in regards to the power button (it stuck out more) whereas mine hardly stuck out at all. I got a warranty replacement this past July (2013) and the exact issues you described began happening. It started out as random reboots and as of yesterday, I can't get my phone to boot because it thinks I'm holding the power button down (therefore not letting the boot process finish). I took my phone apart, expecting the power button to be an easy swap like it was in the GS2, but no, it's a part of the friggin motherboard. I also am looking for a way to disable the power button. I'd recommend that if you are able to get it to boot even once, that you make sure to backup all your stuff. Fortunately all my pics are backed up since I can't boot my phone anymore, but other files are currently inaccessible. I wonder if anyone knows if some sort of electrical tape or something could prevent the power button signal from transferring so that we would be able to boot our phones?

I had the same power button issue with my Captivate as well... and thought that issue had been looked into. After 14 months of use on my S3, I noticed this issue appeared.
Solution (well not quite): change key layout to disable power button. Re-map volume down as "power, wake". Yes, by doing this, I am losing volume down button. Also, when the phone is off, I still need to press the power button to power it up. My fix of changing the key layout file won't take charge until after the phone boots up.

[Q] [D2LTE] CM11 Sudden Death issue

Hey All,
I'm currently on the CM11 04/22 nightly, and have made it all the way up to the 04/27 nightly to try and resolve this issue and have not been able to. Basically - the sudden death issue has been hitting me very hard - I can't use my phone at all.
I understand the 04/11 nightly is stable and doesn't have this issue, howevery CyanogenMod does not have this on their website.
Does anyone have this install available? (CM-11-Nightly-20140411-D2LTE.zip)
Thanks so much in advance

I'll be using the phone (say checking my Instagram or reading a book on Play Books) and the screen may be on for about 5-6 minutes. The phone will suddenly shut off on its own. I'll start it up and then shut down again when the phone is loading. It will also sometimes say it has 1-2% battery when it really has 45% (which is what it shows when I plug the phone in).
Hope this clears it up.

I had the same issue a week back. Was the most frustrating thing ever...
I finally narrowed it down to the power button. It actually had to do with the power button switch which is soldered to the motherboard. The power button was super sensative, therefore being engagded at all times, causing the phone to hard shutdown every time I tried to turn the phone on.
How I fixed it:
1. Opened my phone up
2. Broke the switch off
3. Done
Now I use my phone without a functioning power button but it was a quick and free fix so it doesnt bother me.
If I decide to do so in the future, I can also solder a new switch back and get the power button working again.
DO NOTE: This might now be the issue you may be facing, so do your research
Finally, I watched this YT video which showed me how to break the power button switch and eventually fix my phone: https://www.youtube.com/watch?v=3Glllc7bEJs
Good Luck

I'm fairly confident that this isn't the power switch. And if it were I'm not sure how comfortable I would feel breaking the power switch off.
The thing that begs me to think this is a software issue is that I'll have 45% battery, the phone will die, and then I'll try to turn the phone on again only for it to tell me I have 1% battery left. I'll put the phone on charge (after it dies again) and it will say charging - 45%.
Anyway I've rolled back a few updates and it seems to be fairly usable now...

Try cleaning the USB port real well and don't use a cheap cable. Use a needle and make sure there is no lint packed in there. These things can cause the phone to cycle itself even when not plugged in. I've fixed several doing exactly what you describe.

Power Button makes volume go up instead of tablet sleep

So whenever I push the power button on my Nexus 7 the volume goes up instead of the screen turning off. I have never had any issues, until the last two days, with my power button. I have tried two different ROMs with the same result...I suppose that means it is a hardware issue
Anyone else have this problem?

Did you wipe your internal sd card when you installed the different roms? I've had it happen to me where data got corrupted, and installing a different rom produced the same problem. I've never heard of software causing the hardware to confuse the buttons, but if you're able to turn the tab on from power-off, it would indicate that the hardware is functioning properly where no software is running.
Hardware-wise, the only connection point is between the power cable and the connector on the motherboard. You might disconnect, inspect both, and reseat the cable. On the cable, the power and the volume clickers are so far apart, I don't they can be shorted. But just to be thorough, the only part that might split is on the back side of the cable - which means you have to scrape it off the bezel to inspect. And here, you need to be very careful, as you might cut and damage it.

Thanks for the tip, never tried opening my tablet before...
I am able to power on my device, however everytime I do so it boots into Recovery first (which is better than the alternative of not powering on at all)
I am also able to power off the device, however I can only do this through 3rd party reboot apps or by holding the power button down for 10 seconds (it shows the volume panel the whole time I am holding it down)
I am guessing this must be a hardware issue, but I am hesitant to open the tablet up without some very specific instructions. I am a firefighter and I am apt to breaking things

Forget the sledge hammer. You're not on duty with this. Be a kid instead. With a bit more information, I'd say it's software. There's no reason a hardware malfunction would cause the tablet to go to recovery first. Further, if you can shut it down by holding the button for 10 seconds, it's working properly.
I'd suggest you backup all your apps through Titanium Backup, or backup the whole tab to a flash drive (if you're on a custom recovery). Then format your internal SD with TWRP twice (you also have that option with Philz Touch, where it asks you if you intend to install a new rom), and reinstall a rom from scratch. Power it on like that. If it ain't misbehavin', you'll know.
Past it, restore your data, either from TWRP or Titanium. with the latter, restore the apps one by one to check which one was causing the anomaly. It's a pain, I know, but all troubleshooting procedures are. Try it first. That failing, you can think about opening the thing. Actually, it's very easy. I can guide you if need be.

Have you tried using some app to change the purpose of hardware buttons?

Any fix?
Did anyone manage to fix this issue? I'm facing this exact problem with my nexus 7now. Power button changes volume up.

Random crashes - unless power button continuously pressed

Hello all,
after leaving the tablet for 1y I gave it another try and am seeking on one hand some general advice how to proceed, or possibly specific if somebody had that bizarre behavior or something similar.
The problem is mostly described here: https://forum.xda-developers.com/t/my-sm-t800-will-not-boot-normally.4016731/post-82060775
Now I fiddled with it a bit more and the status is:
- switching it on causes it to crash at arbitrary stages: directly after the samsung logo, while showing the lineage os logo, right when ready for using, any time later, sometimes it is even possible to use it for hours
- it works almost reliably when I keep the power button pressed
- entering download mode is possible without problems
- entering recovery mode works only sometimes, in most cases only with power button pressed continuously
- when it works "normally" I can enable dev options, connect adb and do whatever I want (as it seems)
Now since the device is fairly old, I want to avoid major investments, however I still have some hope that there is a way to fix it. However, I'm a bit ouf of ideas ...
Any suggestions how to proceed are very appreciated!

I know this reply is one month late, but I think I know the reason and fix. The exact behavior happened to my T800 but I was able to fix it after viewing this video:
It is the power connector to the motherboard, which is apparently not soldered. Once I have soldered the pins to the motherboard. All is good.
