i can't unlock it

Today I noticed that the power button does not work because when I can not unlock, but to remove and replace the battery automatically turns on what I'm thinking is that the power button got stuck
any idea?
Going to need alot more info. Where you running stock or custom rom?

im not running a rom, i stay in stock rom.
all started when I received a text message and read the message, when I wanted to block it and not work the power button. I have noticed that sometimes it works with a few strokes with my fingers but it shows me if I turn off the phone. I believe that the power button is stuck
Sounds like a warranty exchange

sometimes with few little strokes xD
when I put the battery automatically turns on, but if I keep pressing the 3 buttons combo I can enter recovery mode, but don't works power button in this mode =/
I'd try an clean around the button and if that works
I am not sure thus will do anything but if you can't get your phone running at all you can try to Odin flash stock to see if maybe it clears the problem. If you cab get into recovery then the power button works for something

yes that's the problem, i cannot get to enter to download mode Because the phone will automatically turn on
Try this. Take battery and sim out. Plug USB in. Hold volume up and down. Put battery in.

Inzombie, what exactly did you do? I have been having the same problem for quite some time...I was able to get into download mode using a program I found on the internet, and I flashed back to stock but the power button is still messed up, it doesn't work at all. What exactly did you do
i know this is an old topic but I have the same problem. I got this phone from a friend and now I cant use the power button. I have taken it apart twice now trying to fix it with no luck. I know it isnt the rom. The button is "stuck" but it still clicks. I know it is stuck because it will never turn off. Once battery is in it turns on, and for 3 button recovery, I only need to hold the vol rocker.

Unable to turn on

Hi
I've problem with my nexus one. Everything was OK until one day my phone won't start. First I think that it's problem with power button because charging seems OK(orange led and after charge was green) so I buy board with new power button. After exchange bord it was same. Phone still wont turn on. I bring my phone to local shop and try brand new battery but nothing. Also I try factory reset and some other tricks for "power button problem" but nothing.:crying:
I'am sure that new board was replaced correctly.
Thank you for any solutions...
Yeah you should be crying sorry for ur lost.

Optimus black soft keys random clicks

My phone is now unusable, once you turn it on the soft keys will light up on their own, any idea how to fix? It will randomly click home button and will exit everything you're doing.
Could it be my screen digitizer? I'm running the ics leak.

Can`t turn my Xeperia Z on

Hi,
i got my Xperia Z yesterday and already have a problem. Yesterday in the evening i listened to some audible content. I didn´t turn off the app, because it goes in sleep mode after finishing the downloaded part. I had stamina mode active. Today my phone doesn´t react. It is off the screen is dark. I can push the powerbutton how i want, the phone doesn´t react. I tried to recharge it, because i thought the battery was completly empty, but i don´t even have the led active which is normally active when you plug in your phone.
Does anybody have had the same issues? And can give me a hint what to do? Otherwise i will have to change the device tomorrow. It´s my first sony, so perhaps there is a trick with it i don´t know.
Take it back.

Hardware reset combination...similar to a battery pull for devices with user changeable batteries.

Can some1 check temps?
Might be a safe mode of sorts due to overheating?
Sounds like this is a common issue on the forums.
i don´t think its because of overheating. Today it was two times in sleepmode for a bit longer, and after both i had to restart it with the method mentioned above. I think it is a software failure. Maybe something with the staminamode. I will switch the staminamode off and wait if it happens again.

I imagine a small firmware update will fix this. Be sure to report it to Sony every single time it happens.
Yes, i will do that. Bsides this bug, i´m very satisfied with the experia z, even with the battery life.

You don't have choice if the phone freezes
Sent from my GT-N7000 using Tapatalk 2
Ever since they introduced non-removable batteries with XS ( and I still have a bone to pick with Sony regarding that choice ), they introduced a hardwired phone reset/shut down combination that is accessed via volume up+power button, that apparently by the sound of this thread, still functions the same as it did with S.
I've had my Xperia S freeze in middle of something ( can't remember what ) after it went to standby mode, and the only way to fix it is either to wait for your battery to die, or to manually reset the phone via volume up+power button combo.
It's safe to perform as much as you'd like, it just resets the phone or shuts it down, depending on how long you keep it pressed. It saved my Xperia S from water damage on one occassion, although I guess I won't have that problem with Z.
The same thing happens with my nexus 4.. Its somewhat related to hardware I guess. Cos xperia z and nexus 4 are very simpilar in case of hardware. around 10% people are facing such problems on nexus 4. Its a hardware problem I guess..

try giving it some foreplay ;D

Did I brick my One?!

I flashed ElementalX (been a long time since I've OC'd) and now I can't get past the HTC screen. I hold down the power button and it just blinks to no end. This is why I like removable batteries. Do I have to wait until it dies or what?
Try holding down vol down then power let it blink until it reboots

Try holding the phone under a bright light and vol down power

Can't believe that actually worked. Someone on Reddit told me to so I did. I thought that was for people who had problems in a call or something...

try holding down the power button until the home and back button flash 15 times then let go of the power button, then press and hold the power button again and wait for the home and back button to flash again and it should shut the phone off. then you can hold the power and vol. down to boot into recovery. this happened to me and thats what worked for me. hope this helps

My understanding is that sometimes, the light sensor gets tricked into thinking the phone is in a pocket/covered and locks the screen off as a result. Seems a little odd, but then again I've never had this kind of issue with any other device I've owned, and it seems reasonable enough to believe.
Is Elemental a Sense-based kernel though? This issue has mainly been cropping up on AOSP ROMs/kernels (which forced me to revert to a Sense 4.1 ROM. )

wow i can't believe that did it, thank you! thought i was screwed. tried all combinations of holding power/vol+/vol-... whispering pleadingly to it... sure enough holding the #$%^& thing up to a bright light and vol- plus power did the trick. :good:
