Power off doesnt work - Xperia Z2 Q&A, Help & Troubleshooting

Hi all, as the title suggests, what once worked for me and im sure most of you no longer works for me.
I press the power button to get the menu. airplane mode, screen shot etc all work but when i press the option to power off nothing happens.
If i hold it down for a few seconds to get safe mode, this does work but instead reboots into safe mode which isnt what im after.
The only work around i have found is to remove my sim card which initiates a reboot.
Its not critical but not sure why all of a sudden this no longer works for me. Any ideas?

Only thing I can think of is to make sure that quick boot isn't ticked in developer options, on mine with that option unticked the phone powers off fine but when quick boot is ticked & you press the power button then tap power off it nothing happens other than the power menu vanishing.

Your welcome mate, glad you got it sorted

Another thing to keep in mind in the future is if you have a hard crash, you can force power-off/reboot if you hold volume up + power or press the little red button next to the sim-card tray.

[Q] Power Off Shorcut

Hello, i`ve upgraded my s2 to ics and i have a inconvenient.On gingerbard, holding the power off button would showed up some shorcuts including the 3g activation.On ics if I hold the power off button it shutdowns directly.Is there any possibility to make it do the same action as on gingerbard?Is there any alternative for activating the 3g without going deep into the settings?Thanks

That's strange. I don't think that holding power shuts it down directly without power menu (unless you hold it for 8-10 seconds, then yes it's normal, but I don't think that's what you mean). Maybe something went wrong during the update. Try reflash maybe, or reset to default...

ive tried like 4-5 diff ics versions today.Everything is working perfectly but the phone shutdowns directly when I keep it pressed instead of showting shorcuts like gingerbard does.Maybe i`m missing some option, some check box unchecked but I didin`t find any option.

Official Samsung firmwares? I find it really strange. It should have a power menu. (you are holding it just 2-3 seconds right? Not 8 so you are forcing it to shut down).
I'm sorry, some other expert will help you. But stock firmwares and custom ROMs, they all have power menu. I've never seen any firmware/ROM that shuts down directly.
Sounds like you're missing /efs/imei/keystr
Create a file called keystr in /efs/imei and put "ON" in it.
wow, you are a genius.Everything was fine and working except that holding thing and I also had no screenlock, it was just getting to the menu if i would have pressed home button or power off.I fallowed your instructions and they were both fixed.Thank you very much.

Evo lte is stuck in lock screen, feeling withdrawal symptoms already

ok so I'm new to this forum, was suggested to go here when i got my first smartphone.
So basically my idiot friends were messing with my phone with the pattern lock. They messed it up 15 times and now I have to sign in with my gmail. But the problem is that whenever I try to sign in, it gives me invalid username/password. I know I'm putting in the right password and right username because I've done it about a million times on my computer and tried to unlock my phone about the same amount of times. I've also tried all my other gmails that my phone is registered with but none work.
I'm still on stock ICS because im new to the android world and haven't gotten around to figuring out everything. Thanks for helping!
Okay first did you possibly have your Android debugging on? If not the only way us a factory reset. You can reset it by turning it off, hold down power and volume down. While holding volume down let go of the power. Then using your volume keys select factory reset and select with the power button.

Okay so first press down the Vol. Down button. Next press the power button firmly for 3 seconds. DO NOT let go of the Volume down button till a white screen (Your bootloader) appears. Then use the volume buttons to select factory reset (If it's not there look for bootloader or somthing like that) press the power button to select.
Volia your phone is now factory reset!

remapping the power button

Is this possible? I just want it to not turn on the screen. I notice in my front pocket sitting down sometimes the power button gets pressed and turns on the screen. I would prefer the home button only cause it is flatter and more flush with the device. I am able to edit the home button to either wake or not wake the phone, but the power button wakes the phone even when I erase the fields in all the system/usr/keylayout files. There must be a backup file or something somewhere telling the power button to turn the screen on. I use WidgetLocker also.
Are you sure it's not the home button turning your screen on? Pretty common occurrence...

No. I have disabled that and will leave it disabled until I can figure out how to disable the power button.
i would like to see this as well, the power button is too easy to press accidentally. i tried editing the keylayout files but i couldnt get it to work either.... here's my ideal setup: the home button wakes the phone, the power button does nothing unless you long press it to bring up the power options menu. or press it while the screen is on to turn off screen.
I too have this problem.
The power button is easy to press when it's on my pocket and I even have a case on it. The case makes it a little harder to press but I can still hear the click of the button when so I know when it happens.

[Q] Volume Button not working

After Rebooting the HTC Radar yesterday, it reboots every time in "Serial Mode". There are some options on the Screen like APPSBL, Image SRC and Factory Reset". Every time i long press the Power Button, it comes back to this Screen. Today in the Morning i preset Power + Volume Down + Camera Button and it boots up normal. All Data are there, but i cant use the Hardware Volume Buttons anymore. If i press this Buttons, nothing on the Device responds.
Does anyone have a idea, what i can do? The rest of the Device seems to work ok.

Now after some days, they work both. First only the volume down, some days later, also the Volume Up. I think there was some steam in the shower which disfuncts the buttons. but thx for your suggestion.

Power Off?

Anyone else got an issue where you can't power your phone off? Long press power button brings up the menu, selecting power off, does nothing?
Still on .55 firmware in UK.
Cheers
