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

Hey guys,
Oh i dunno whays happened. Everything worked fine yesterday then i went to sleep. Next day the side buttons stopped working. The touch screen still works but the side capacitive buttons stopped.
It doesnt even work when i boot into clockwork mod
I have so far tried:
Reboot did nothing
Put calibration.ini file in root directory
Put calibration.ini in sdcard2
Put calibration in sdcard root
Reboot
Didnt fix it.
I got it ebay as i live in australia so warranty may be difficult.
I am using button saviour to get by for now but until i can get the side buttons to work i can no longer navigate clockwork mod because the home button is the select button.
I'm usibg vegantab b5.1 at the moment.
Any help would be really appreciated!
BAM
If you haven't, you might want to try this: http://forum.xda-developers.com/showthread.php?t=934500
Just tried it but still no joy. Looks like the side buttons are on a different touch interface to the rest of the screen. I guess it could be worse. Vegantab is a nice rom to be stuck on.
I wonder if there is a way to make clockwork mod work with a usb keyboard?
Woohoo! It's working again! Just in time for honeycomb too
I searched and searched for similar issues and finally read about either draining the battery or opening up to find the hidden reset button.
I opted to drain the battery.
Now I'm still not going to rubber stamp that draining the battery fixed it but when I did finally plug it in and fire it up I found the buttons worked again.
Another theory I have is that viewsonic might have some poor soldering. The reason I suggest that is because in Australia we've had some stinkin hot days here at 42degrees Celsius with high humidity. So it wouldn't surprise me for a dry solder to become temperamental under these conditions.
Anyways happy ending for now. Well hopefully it'll keep running until a reliable honeycomb rom turns up for gtab hey
I have encountered a similar problem. The side buttons stopped working after a few days of use. They do work sometimes randomly. Is there a reliable solution to this problem?
I tried calibration.ini, and the buttons worked once. They have stopped working again.
I've just installed the new Revolution HD 3.2.1 and the latest Kernel 16b.
The tablet is very fast and stable now, no more reboots. There are only two things that happens and that's Dolphin browser crashes sometimes and when my tablet is off and I want to start it up, I have to use my power cable otherwise it won't start up. If I want to use the battery only it won't start up. Is the anybody else with the same issue?
how long are you holding down the power button waiting for start up?

20 or more seconds. Normally it worked fine but lately it went from bad to worse to nothing!
Same here
Mine is doing the same thing. I flashed another ROM (was using Revolution) thinking it was the ROM, but no. I have done a lot of reading and still am not sure of what is causing it. Some say the power button is wonky and the tablet needs to be sent back to Asus, but when it is booted up the button reacts just fine to sending it into and bringing it out of sleep. I am perplexed.

Exactly, the only time the button refuses to work is when the tablet is off and I want to turn it on when it's not on mains power. But as soon as I put the main power cable in the tablet I don't even have to push the button it just goes on
and if I want to flash something and I push the power button and the volume down button, it works. But the main power cable must be plugged in.
RMA'ing mine
After researching until I was blurry-eyed I decided that it has to be a hardware issue. I unrooted following the Unlockr guide and flashed the most recent stock build (.24) from Asus's support page so I could send it in for service. (I couldn't get a download for the stock ROM from the Unlockr link and that's why I used the one from Asus...just unzipped main folder and moved to SD card from my PC, then inserted card into the TF101. As soon as SD mounted a notification popped up saying that there was an update ready to install.)
Also, another strange thing is that I can't connect it to my PC. It just says USB device unrecognized. I tried EVERYTHING and no luck. I really would have thought that returning it to complete stock would have solved that issue but no. Hopefully when it comes back I'll have that functionality back too. I have my doubts but we'll see. Maybe one of those custom kernels I flashed that were associated with Megatron's ROM did something with the firmware that flashing stock couldn't change. I really have no idea and I don't recall trying to connect to my PC with it while I was on Megatron's ROM so I don't really even know at what point it stopped working. I will say that it was my favorite ROM.
Hey, the power button broke on my nexus s, YYAAYY
the problem is, that it is not just broken, but it is also sorta stuck... what i mean by that is, instead of not being able to press the power button, it is constantly pressed. this means i can not:
1. turn off the phone
2. use the bootloader, which is actually a huge problem, as i havent rooted the thing yet (or rather restored everything to factory a while ago)
3. lock the screen.
what now? i openend it and i cant figure out what is wrong, the button seems just fine on the motherboard, i can even press it, the internal contact seems to be stuck or something. is there any way i can fix that? can i disable the button on a hardware level entirely? or am i missing some way to make it work here?
please help

u need tools to do that, a hot airgun. Just pick up the solder that holds the button and button vl be in your hand so get the button replaced
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.

Cheers, I have cleaned with an air can and a glasses cleaning cloth on all surfaces accessible for following a replace your battery tutorial and this has so far fixed all issues that I was having.
I have an old phone used only for mapping which has worked perfectly for years until a walk 3 days ago, after which I came home and removed the battery for charging. It is now booting direct to the Recovery menu, with a selector arrow rotating between Recovery / Fast Boot / Normal boot. No combination of volume up/down and/or power button makes any difference, the selector arrow keeps moving from one option to the next without pause until the battery is removed.
Phone is a Zopo ZP920 running Android 4.4. I have two removable batteries. The USB socket is broken, I can't attach it to a PC or charger. It's never been rooted.
Is there anything I can do to make it boot normally again?

Nope, its gonna require connecting to PC.
Your options are:
1) get the USB port replaced on the device.
2) replace the motherboard in the device.
3) get another device.

One other possibility is the power button might be sticking. Does it continuously boot to recovery then power off and boot to recovery again repeatedly? If so, I'd say the button is sticking.

If the device has a stock OTA update.zip that can be flashed in stock recovery available and if your device has a removable sdcard, you can try downloading the update via the internet then put the update.zip on the sdcard then boot to recovery then try applying the update from sdcard. If the update contains a system.img, it might fix your device.

The selector arrow cycles through the three options and nothing I've found will invoke actual selection. That's without an SD card in place, I'm doubtful it'll change but I'll look for a zip and give it a try. tvm.

Is it automatically cycling through the options even if you aren't pressing any hardware keys? Could it be the volume rocker is sticking? Not the actual button itself, the hardware components on the inside that the rocker actuates when pressed up/down? It is tricky to tell whether or not the components are sticking, a mixture of sweat and dust works its way behind the rocker over time and can get down inside the components that are the actual buttons and gunk it up such that the button doesn't click/unclick as it is supposed to. Opening the case and cleaning the button component behind the volume rocker with alcohol and a Q-tip while actuating the button can loosen the gunk and wash it out, then just wait for the alcohol to evaporate, then reassemble the device, then try powering it on.
