My Z1C power (on/off/lock) button doesn't work anymore. I cannot wakeup the screen, neither lock my phone . Instead it crashes the phone few seconds after pressing the power button. Strangely a hard shutdown of the phone works (power button + volume up), so the button itself still seems to react. But instead of turning the phone off completely it directly starts up again. Could this be a HW or SW problem? Btw. I'm using the latest CM12.1 Nightly.

I bet on softwarefail, make a backup of your whole system and test with a stockrom.

Hey lads,
this is probably a very dumb Q, but since I am new to all this android schmuzzle and couldn't find ballocks on that, don't judge me too hard ;]
I've noticed that when u press both VolUp and VolDown ( put pressure kinda in the middle or the rocker ) the phone vibrates once and then after several seconds (seems to vary) it vibrates three times fast. Now what the flick is that? Not that much of a big deal but it gets annoying given that even when the screen is off and the phone is locked doesn't seem to give a damn
thanks
has happened to me too but hard to reproduce. I have no ideas why it happens. Sometimes it occurs when the phone is booting up for me as well.
Put ur finger in the middle of the rocker and press ( not even hard ). It happens every time in my case. even when the phone is locked
I get the same behaviour, sure is strange.
Kinda old thread but I didn't want to start a new one either. I've noticed this too by accident. When you turn off your screen and press both volume buttons at the same time it vibrates once and every other time twice or thrice. If it vibrates only once it will vibrate again a couple of times after about 10 seconds. Has someone found a reason to this already?

Maybe HTC thought "Why not? Let's do this and see how they discuss about it." ^^

These buttons are part of combimation of three finger salute (at least look like that)...if you press voulme up + Down and power button, phone will reboot....so might be vibration is just an indicator to show go ahead and press the power button for restart.......Just a Guess
Pressing Volume Up + Down simultaneously while having USB Debugging turned on creates a bug report in the bugreports folder on your SD card.

I can't get it to reboot by pressing the 3 buttons.

This is correct, there's always a new bugreport after I press the volume buttons. I don't think that it's even necessary to have usb debugging on.
Thanks for the quick answers, but could there be something more to it?

Press the power button first and then press volume up and down..you will get a reboot...
Nope, can't get it to reboot. Perhaps this is rom related?

It shouldn't be, but its really hard to get it if you are trying to press three button, you can try power button and middle vol button......any ways I also tried lot of times before I got my first reboot....
1) Pressing both VOL UP & VOL DOWN at the same time = Vibrations & all processes' states and stacktraces dumped to /data/arn/traces.txt (thanks to alind_)
2) Pressing both VOL UP & VOL DOWN at the same time + POWER BUTTON once = instant reboot
Works for me with CM7 and Stock Sense.
I was playing with buttons of my defy, screen locked or off, pressing volume buttons many times.
Suddenly I discovered that when I was holding vol+ and pressing vol-, the defy vibrate shortly (haptic feedback), one time. And continued to test all combinations again and again, and then I had a three shot haptic return!?
I didn't find if it was toggling some settings, so does anybody have an idea of what it is doing (if it is doing anything...) ?
I'm using stock froyo (nordic).
Thanks.
Check logcat about what happent...

Holding the volume buttons allows you to skip to the next music track if that option is enabled.
Hello, I need help as soon as possible.
Today I was running with my HTC Desire listening to music and also using app MapMyRun. After all, I checked my phone, pressed power button and it restarted and entered to safe mode. I turned off safe mode, and then, when I was pressing power button to lock my screen it locks, but when I want to unlock it, then phone restarts (in safe mode it worked.). Moreover, volume down, menu and search buttons seems to be not working. I have done factory data reset.
Thanks.
Just recently my power button stopped working. I pushed the button to use my phone and it did nothing. For about five minutes pressing the power button did nothing. I had to press and hold up and power button to restart. Is working fine now but What I would like to know is why did this happen? How can I prevent something like this occurring?

I've noticed mine has done the same thing a couple of times since I've gotten it. In my case I think the phone hot boots, maybe you have the same case

Same issue but no case and it wasn't hot. I think it might be software related. Waiting a few minutes and holding the button for 30 seconds finally allowed it to boot.

I've experienced this just once with the same result. Power button + volume up resolved it.
I had same issue pre-root and vol up and power fixed the issue. No power button issue since.

hold the power button at the same time as holding volume up button.... hold both for a few seconds might take as long as 8 seconds
will put you in fastboot mode....(if it doesnt go into fastboot that way can hold power button until screen turns off then quickly hold volume up until fastboot comes on)
once in fastboot tap volume down twice (slowly allow a slight pause between presses) then pres the powere button and you will be in recovery

I can't even get my phone to the fastboot screen. Ive held down vol up and power. Vol down and power. All 3. I'm really at a loss. Any ideas before I just get a replacement? Also, my headphone jack has seemed to stop working along with my power button.

When I have trouble powering on I hold vol up while plugging in usb.
So I have my htc one x for a year now. Rooted and custom rom, all worked fine.
The keypresses of the power button will be simulated very fast with no actual pressure on the power button. So after some minutes off locking and waking my device I pressed volume down and power button. Now sometimes it simulates the volume down and power button.
So sometimes it shuts off the device.
So I opened the device and there appears to be nothing wrong with it. I turned my HOX on and quickly unplug the ribbon cable from the power button off. But the power button is still pressed really fast, like 2 times a second.
I can't even go into recovery to backup, restore or flash anything because it will press the power button really quick and after 10 seconds it turns itself off.
It happened before on Slimbean rom. But the problem went away after some days. Now i got MIUI and the problem is back. So I don't think it is rom related.
My solution:
Is there a way to disable hardware keys in the recovery? Then i can try to restore my official RUU nand..?
