Hello.
I have a problem with my Sony Xperia Z. When I use it (browse internet or just stay in launcher) sometimes it randomly turn screen on and off. Happens also when screen is off and lockscreen is showing out of nowhere. I tried to disable power button and set volume up as my power button but even with using volume up it still happens. What can I do?

Seems like some app is running in the background and turning on and off your screen. There are two ways to go about it but I would like to know if you are rooted or not. because it would only work on rooted devices.
look for Greenify in Google Play and how to use it.
Secondly , check this app. it will tell you which app is waking it up.

I hope this is enough, however, if you need any further assistance, make sure you quote me for an answer.
Good Luck

I don't know what ROM you're running, but MIUI has the option to do what you're asking. It's in the settings menu (I believe under Lockscreen).
oh, ROM CM7 have it also, but I want separate app. Do you know any apps ?
Widget locker. Like 3 bucks in market enable easy wake
Sent from my Samsung Galaxy S Captivate with ICS and a broken power button.

Fix Broken Power Button by Destil
I found this..
market.android.com/details?id=cz.destil.fixbrokenpb&hl=en
When I tried to download it said it wasn't compatible with captivate but I found the .apk and it ended up working. I attached the .apk I was using to this post.
Another thought, I took my phone apart and cleaned it. I took everything apart down to the motherboard and I poured a little rubbing alcohol on the actual button and pressed it a bunch of times (no battery in of course) and after it dried out it seemed to help get it working again.
Also, when I started having problems again I installed a different kernel and that seemed to help as well. Who knows.. but it has been working ever since.

Thank you topiratiko, I was about to go crazy worrying about not being unable to turn my screen on. But what will I do if the phone shuts off? How will I turn it on? My power button seems to be unable to work.

You can allways go into download mode and flash a kernel for ex and check reboot so it'll boot up, or even better use a jig by inserting it for just a bit to power on and to avoid download mode.
I have a Galaxy S i896 (Rogers captivate model), been running CM9 on it for quite some time now and I never had a problem with it.
Until recently, my lock button stopped working. Thankfully, CM9 allows me to use the volume buttons to turn on the screen, and I can lock the device from the notification bar. However, I sometimes get that screen that pops up when you long press the power button (airplane mode, screen shot, reboot etc...) but I don't know how. Also, whenever I remove and re-insert my battery, the phone turns on by itself! So it would seem that the button is stuck somehow, and once the phone is turned on, it is being ignored.
I read somewhere that this is sometimes caused by rooting the phone, however I wasn't completely sure about how true this information was, and therefore my question is: does anybody know what causes this, and how can I fix it!
Thanks!

I also have this problem with a stock ROM. The power button doesn't work and i cant even flash another ROM in recovery because of that. It only turns on when putting the charger on or replacing the battery (turns on by itself).
It seems that your power button is busted. I had the same problem, though I manage to have a way to make things alright. If youre on a CM9/C10 youre good. Download button remapper at remap the capacitive search button and make it act as a power button. So, if you're waking up the phone you will use the volume rockers and if you want to sleep and lock, use the search soft key.

Hello developers!
Having troubles with my Z's screen. Going to explain whole procedure.
After turning device on I can normally use it, everything works problem starts when I press power button to
standby, I cant turn it on but if somebody calls me, display goes on again. I can also normally use power button to switch off so
button is working properly. P.S. If xperia is on the cable, it's also working normally. Is it software problem or what? Have no idea.
Is it possible to have the power button behaviour modified so that it only turns the screen off? I'm hoping there's a utility or setting somewhere.
When the phone is in my pocket it constantly turns itself on and starts tapping away. It never gets past the lockscreen but it's annoying to have battery drained like this.

Are you sure it is the power button and not rather the tap to wake that is activating it in your pocket? (Settings->Display->Tap to wake up)

I had the exact same problem. Tried the following things:
1) Changed the locker - used Nils Locker Master - worked well, but it stopped working with recent 5.0.2 update.
2) Used PIN lock - too inconvenient, and even then the emergency call button would get 'tapped' accidentally while in my pocket
3) Currently using a nice cover which raises the edges around the power button slightly, so it doesn't get pressed automatically anymore when in my pocket.

Thanks but it has been happening for a long time before I enabled tap to wake so that's not it.

Do you have a link for "Nils Locker Master"?
ATM I have pin lock and that's fine.
I prefer not to have any sort of cover/case.

Hi
https://play.google.com/store/apps/details?id=com.qiigame.flocker.global&hl=en
My phone froze last night while listening to music, the music was still playing but the screen was unresponsive. So out of habit I shut down the phone because when I hold the power button the turn off option still happens. I restart my phone and the startup animation shows and after that the screen goes back to black. I have tried a force start using the power and volume button but I'm not completely aware of all of the specific options to do with that. I have a pebble that allows me to control some aspects of my phone over bluetooth and I still get emails and can turn on music with the pebble.

sounds liek a SystemUI crash. if youre stock, you may want to consider factory resetting. if rooted and rommed, I'd reflash your ROM
