Having been on the same version of CM Marshmallow and making no changes to my phone's software/hardware for a few weeks (except for regularly updating apps), my hardware buttons have all of a sudden stopped working. (I have no way to change volume or turn the screen on/off with the hardware buttons)
They also do not work in TWRP. Having factory reset the phone (using the latest official factory reset .tar.gz) , they don't work on stock android 6.01 and updating to the latest CM with open gapps they are still broken.
They do however ALWAYS work to hold down power and volume down for fastboot (even when not working for volume/screen on) and always work fine whilst in fastboot (for scrolling the menu and selecting options, but do not recovery, eg. TWRP)
Any ideas on what may be causing this much appreciated thanks :good:
TLDR: Hardware buttons only work for turning phone on when powered off, rebooting into fastboot, and for using fastboot (so its unlikely that this is a hardware issue, but not impossible). They don't work with any AOSP/CM/TWRP software, and I don't know why...
EDIT: Although not really a work around, I can at least turn off the screen using Cyanogenmod's double tap status bar, and turn on the screen with this app for the light sensor: https://play.google.com/store/apps/details?id=com.wolandsoft.wtn Still no idea how to control the volume though, except for toggling ''do not disturb``
EDIT 2: No fix booting into safemode. Also, the USB connection for charging/data transfer temporarily broke until I rebooted the phone, and I suspect that this may be related
try cleaning with paper towel you wet with alcohol, fixed my mom's iPhone that way.

All of sudden my front buttons (home,menu,back,search) stop working, however those button on the keyboard still works. If i power down and reboot the phone it works again and when the phone goes into sleep, the button stop working again. Anyone have any ideas? The phone is rooted, s-off with cm9 installed.

Not too sure, but I've come across the same situation before. I think it has something to do with not have a the micro sd card mounted. Did you by chance remove it at any point? Just a theory, seems to be the problem for me, I remove the card frequently to transfer files from my computer.
I thought that was the problem also, so i replaced the sd card and wipe and reflash the rom and still have same problem.

I experienced similar behavior with my old mt4gs, it ultimately proved to be a result of a worn flex cable between the two halves of the phone.

isnt the flex cable connected to the track pad also? that track pad still work fine. i know there separate flex for the power buttons, camera, and the the functions buttons
You COULD just move on to CM10 or CM10.1 where you have a navigation bar option you can use to bypass your physical buttons. If you remain on CM9 you can download Notepad++ and go to system/build.prop, open it for editing and add the line qemu.hw.mainkeys=0 at the very bottom of the file. Once you reboot you'll have a navigation bar to use instead of your buttons. (Thank You Jesterfell)
Same problem for me. Fixed by replacing the flex cable.
i went back to the stock rom, so far it working again with no problems
Hi guys,
My girlfriend has a galaxy s6 running marshmallow. The soft keys are constantly flashing/blinking whenever the screen is turned on. This also causes the device to lag, draining the battery.
I've tried factory resetting the device, and running it in safe mode suggesting it's not software related.
I also installed the the app "Galaxy button lights" that allows the control of the lights, this does stop them flashing, but the device still seems to be running slowly.
Thanks for any advice in advance.
Hi did you find a solution to this as I am having the same problem. Power mode on stops the constant flashing but the phone still lags and it flashes when I charge my phone. My power button also phantom presses :/
I have the same problem. Did you find a solution?
Me too. Turning off the buttons seems to help... it drives me less crazy... but it still feels like there is screen lag. I think this started after I installed the last system update.
One of my co-workers suggested that it may be caused by moisture inside the phone. I set it in the sun for a while, and the problem seems to have gone away.

This happened to me like 4 months ago, it hasn't "dried" till now However if i press hard on the lower left bezel - next to the app switcher button my phone works. I have a theory that the contact has become loose under the phone or so?
Hi, I have the same problem for a long time I installed a couple of firmware and the same thing on the factory software always happens, now I use custom rom and it works without problems, it means only on the factory versions I have a problem
Hey guys,
strange and frustrating problem. I was using my phone pretty extensively today (although nothing crazy), mostly thanks to Pokemon Go. Tonight after using my phone normally, I went to press the power button to turn the screen off and nothing happened. I was able to reboot (by changing one of the long-press actions to bring up the power menu via GravityBox) and then was unable to power on the phone. It seems like my hardware power button has suddenly become unresponsive. This leaves me unable to power on/off the phone, including booting into the bootloader. Also, I seem to be unable to wake my phone up by double tapping the screen or swiping up.
The phone otherwise functions fine. If I get a notification, the screen wakes up and I can use the phone. Otherwise, the only way I've been able to get into the phone is by connecting it to a computer and issuing ADB commands. The IR blaster functions fine which makes me think it's not the hardware button?
Has this happened to anyone else before? Can the power button just break like that without any water / physical damage? The fact that I also can't wake the screen makes me think it's a software issue. One other thing I suspect is that my phone abruptly died yesterday (battery died despite software thinking it still had juice left). In the past, with the modified kernel / rom, this has resulted in some nasty issues, including 4G not working and the Android system process basically exploding. I thought I lucked out when I powered it on after that, but maybe it just took a day for this issue to manifest itself.
I'm going to make a NANDROID backup and try flashing a few different things to see if I can fix it. I'll post my progress here.
Current build:
- Verizon M8, S-OFF
- TWRP
- Android GPE 6.0 (MRA58K.H13)
Edit: I haven't been able to find a fix. I'm a bit afraid to try a full RUU since I can't use the hardware keys to reboot into the bootloader should something go wrong. It may just be that my PWR hardware button is f'd which really sucks. I'm not sure I'm up to cracking open the phone to fix it. In the meantime I downloaded an app called Gravity Screen On/Off which uses the phone's proximity sensor to wake the screen up and it seems to work ok for now.
An hour or so ago everything worked fine, and then I updated my playstores pending apps (only Fleksy was pending) and the "force touch" feature of the phones seems to have completely stopped working, no matter what setting I turned on or off it didn't work...
Anyone has a clue as to what can cause this?
General notes:
1. Using stock Exynos unlocked variant
2. I am using package disabler (which btw didn't improve much my battery life, but that might be just me using the phone too much ) so maybe one of the packages decided that it depends on a disabled one?
I noticed mine stops working after a reboot and takes about a minute or two to get back up and running. Try a restart after clearing caches, if nothing still, reboot in safe mode. If it works, then its an app you installed interfering.

Mine also stop working after I restart my S8 Plus, it will again work if I wait around 20 minutes. Is this software or hardware problem? Any solutions?
Wish mine would stop working permanently! can't stand that feature forever brushing across it and waking the phone up!

How does it act up on your part? Mine would just stop working if I restart the phone & I should wait sometimes hours before it would work again.
Every time i'm installing my phone in my car mount I need to hold the phone from the bottom to install it correctly and brushing my fingers across the bottom is constantly waking the phone up, I've lowered the sensitivity to it's minimum.

I see, problem is not the same. On my part the tactile home button simply doesn't work when you press on it. I have to double tap to wake the phone when on lockscreen.

Unless your phone is unlocked no pins etc the phone will just go to the lockscreen, it's a useless feature, most people have the phones locked and thus it's a complete waste of time, it sounds to me the capacitive home button part of the screen was an afterthought because they couldn't install the fingerprint reader under the screen, just had a software update yesterday and still can't turn it off, basic stuff Samsung should enable an ON/OFF toggle switch for this.
Had the same problem with my S8 Plus India Variant(SM-G955 FD), I got my screen replaced from service center, Device was not rooted back then, so was under warranty.
But it is an hardware issue, as since then it has never gone off.
I mean when I press the home button hard it doesn't wake the phone up & no vibration. It happens when I restart the device then it would stop working for few minutes to a few hours sometimes, then it would start working again normally until I restart the phone again. I think this is just a software issue.
Over the last couple weeks, I sometimes had the problem, that the S7 would just reboot randomly, sometimes multiple times in a row, after freezing for a few seconds first. It seemed to get better when I switched it off for some time and let it rest before rebooting.
Now yesterday it started crashing and rebooting again. But it would only go up until the lock screen, while being quite laggy. Sometimes I could swipe away notifications before it crashed, sometimes not even that. When I typed in the password, it crashed at the latest. Then, later, it would barely show the lock screen before crashing, only scaling up the brightness in steps, again very laggy.
Today, I can't even get the phone to the lock screen. After the Samsung and Galaxy S7 logos, the screen would go black (also, when the Samsung logo starts appearing for the first time in this drawing motion, it only draws a little party of the first "s" before freezing for some time). If I touch the home button (and sometimes the power button), the soft buttons would light up (but only once, if they go dark and I press again, nothing happens). But no lock/ start screen whatsoever.
What I tried so far: hard reboot, wipe cache partition, factory reset, both combined. Tried flashing TWRP to get some more options, but it doesn't let me due to this fap lock.
Also, I can only get into recovery mode by pressing power + down + home, then in download mode selecting the restart option, and then applying power + up + home.
Had anyone had this problem before, or any tips what else I could try?
Flash stock with ODIN 3.12.3 or newer?
I will try flashing 6.1 or 7.0 and report back whether it worked.
It didn't work. Though now, sometimes, when tapping the screen it seems to recognize button presses. Also, the voice assistant keeps randomly bursting phrases.

If flashing a new firmware with ODIN doesn't cure the problem then it's most likely a hardware problem.
Dammit. Since the back has a crack, I doubt they'd repair it... Thanks anyways!

Yep unfortunately it sounds like a hardware problem, did you use CSC with the other 3 firmware files?
CSC = Factory reset after flashing (Use this one)
HOME_CSC = No reset
You could try checking the "Repartition" box in ODIN options tab to ensure a clean flash
Make sure you use ODIN 3.12.3 or newer too

Voice assistant is not enabled by default, which sounds like something is pressing either the screen or buttons to activate the setting
Which could also be a reason why nothing else responds properly, imaging holding your finger on the screen, then using your other hand to try and use the phone
Possible the digitizer (touch panel) across the screen is damaged, or possible that a button(s) are damaged and permanently pressed in
