Power button lost the ability to lock screen?

I recently found out that tapping my power button will not lock my screen or put my phone to sleep mode. Any solutions to this?
Details of my phone in my signature

Can you still long press the power button to get to the shutdown menu?
It sounds to me like you might need to warranty your phone D= (FYI if you didn't know - unlocking the bootloader voids software warranty, not hardware warranty)

Yes I can still long press it and the power options still show.
Just lost the sleep mode.
Things I've done recently to my phone:
Flashed IntersectRaven's Kernel
Upgraded Amon Recovery
I wonder if one of these caused this problem.

Hmmmm well my best suggestion at this point is to reflash everything to stock and see if the problem persists. If it goes away, I'd say there was some kind of error in the ROM you flashed to your phone, or possibly a setting.
Unless someone else has any bright ideas?

Thare's an "End button behaviour" option in Spare parts that might help.

What if the power button break?

Mine is a stupid question.
Looking at my new nexus s the hardware buttons are protruding unlike the old motoria milestone.
They feel not so rocks so I was thinking, what if the power button break?
How turn on the phone or wake up it? How to enter recovery?

if you're worried try to use it as little as possible
my nexus s wakes up when i touch the screen and locks when i put it into my pocket (proximity sensor). So i use the power button about once a week to reboot.
but if it breaks nontheless - send your nexus to samsung they'll fix it.

ive been with a broken power button for almost 5 months now. i use the volume rocker to wake, and the lockscreen widget to lock the phone. also, i use the twrp recovery that has options to use for a select instead of the power button. ive even forgotten that i had a working power button

I would just contact Samsung the phone hasn't been out for a year yet. They should cover this just make sure your phone is unrooted and running stock.

Ok I understand that it's possible to use the phone also without the power button but how do you turn on?
How do you enter recovery without it?

How do you have this function? What rom do you use?

CM7 has the wake key functions. CWM recovery also allows the use of the soft keys.

many ways..
in the terminal emulator app type..
su(press enter)
reboot recovery(press enter)
or there are many apps that will boot you into recovery, like RootBooter.
if all else fails, you can enter recovery via adb or fastboot too, via your computer. once you stop using the power button, you will "see" many ways around it. there are root apps that can remap your buttons too.

i gently flick the back of the phone(right under the lens) with my finger), and instantly, the phone powers up. since i test the trinity kernel before releases, i get many that dont boot, and need to go straight into recovery to flash another kernel so that my phone could boot. i do the same thing with the gentle flick to the back of the phone. i boot the phone into fastboot mode, select recovery, then instead of pressing the power button to select recovery, i gently flick the back of the phone right under the lens and the recovery option gets selected. from there i flash another kernel(or rom) and boot the phone. i havent had any issues for the past 5 months doing this, and i flash many times almost each and every day.

Hope it works for you.

Hi, my little italian friend ! I hope you will solve your problem

I have to say, i am truelly interested in how you can get your phone to turn off when you put it in your pocket. Would save me alot of button presses.
I'm currently looking into the Cyanogen 7.1 lockscreen menu but can't seem to find anything for the proximity sensor.
Please enlighten us.

Could you tell us more about your setup? How did you managed to lock it by putting in your pocket?
EDIT: didn't realize there are more pages in this thread, so another user already asked my question. Waiting for the answer...

[Q] Power Button Not working. Plz help

Okay so my power button just randomly stopped working after some random time. it doesnt work ANYWHERE. to lock my screen, to unlcok my screen, in recovery mode i cant press anything cuase it doesnt WORK. i no its a hardware issue becuase of this. i did google this but found nothing. what can i do to fix it.
i tried a battery pull and putting it back and going to recovery to factory reset but as soon as i put my battery in my phone starts up. i can enter recovery but the power button doesnt work so i cant press anything.
my warranty is over by a long shot ( had it since it released) so cant return it.
any help would be appreciated. all i need is a way to turn my phone on and off nothing about the recovery and stuff. but if you do find someting for it that would be even more amazing.
and has this happened to anyone else, just wondering is all if this is common or rare.
thnx in advance.

it has happened to many captivates. search 'captivate power button' on xda.
What ROM are you running on your phone?
Answer to that question has a lot to do with your next steps for software workaround.
One approach; you could read up on ways to clean the power button and see if that works. Or send it off to mobiletechvideos.com and he will fix it for a reasonable fee.

i am running Aocp 5 android 4.2.1
hve been running it for a few weeks now and no problem till now

Okay, start by seeing if you can clean the power button, that may fix it for now. Again, search 'captivate power button' to find some threads about ways to clean it.
With the ROM you are running, I believe you have a version of CWM that allows to use the Cappy's dedicated menu keys, menu, home, back and search, to navigate and select recovery items.
Assuming your power key is stuck on, remove the battery, hold the up and down volume buttons and reinsert the battery to get into recovery. This will allow you to test keys, wipe, and any other function in CWM.
With the phone on and fully booted into JB, go find volume rocker wake in the system setting options and make sure it is active. Hitting the up/down key will wake the screen when it sleeps. Add the sleep/lock toggle to your notification bar menu and you have a way to instantly lock the screen without the power key.
If you still have a bad power button stuck in on position, then you will need to take out the battery to turn it off.
Hope this helps.

Thnx for the help but Which button does what?

Menu = Down. Home = Up. Back arrow = Back. Search = Select.
This is the way it is in KK4 Corn Kernel. Not sure about the recovery in AoCP though... Home may = Select. ??

This is happening because your power button is stuck in the on position. Did you try to clean it as suggested earlier.
BWolf56, I'm not aware of an app or ROM that completely prevents power up on insertion of battery when the power button is stuck on. If there is such an app, I'd like to hear about it. I think maybe the power switch goes to the broadcom power management chip, so I don't understand how the app could work unless the phone never came on at all. SOD symptoms would be the result.

Oh that would be impossible, the OS isn't loaded so even less the apps
I was suggesting a app to turn off the phone/lock screen. There are widgets for that in the market.

I had a very similar problem with my Epic 4G Touch (Sprint S2) - my phone would randomly reboot, and it kept getting worse and worse. Thought it was the ROM, the overclock, etc. I flashed back to (almost) stock, went back to original clock speeds. Eventually, I noticed that even brushing past the power button would wake the screen, and about 10 seconds later the phone would reboot.
Long story short, I bought a replacement power switch, soldered it in place, and have had zero problems since!
Several eBay sellers offer the switch you'll need.
(They don't include the skills needed to solder it in place. It's a tiny switch - about 4mm x 2mm x 1.5mm, and you'll need a good quality fine-tipped soldering iron and a steady hand. Do you have a friend who's good at soldering?)

well thanks for the reply, but i dont need it anymore. my friend conveniently had a GNex (old) and gave it to me as a present. so i dont use my captivate that much anymore.

Can you change the bootloader? - Hard reset no longer working, Any insight?

So I have been trying to overcome the issue of power + vol up (held for 10, 15 seconds\ and more) not working on my device. No matter how long I hold the two it just won't reset the device.
At first I figured it could be kernel as that is the lowest code that I've knowingly changed.
Changing to back to stock kernel did not fix it.
I thought it could be any sort of thing so I redownloaded the NL 434 firmware and then also universal generic 434 firmware and flashed back to completely stock with flash tool, doing all wipes and excluding nothing.
Neither of those firmwares fixed the issue, the hard reset function still won't work on my device.
Additional info:
Both buttons function fine individually and can see no obvious reason to suspect it's a hardware fault (though see that it is feasible, just less likely).
I can confirm that it was working initially.
I have an unlocked boot loader.
The last time I can remember it functioning was prior to boot loader unlocking - the first thing I flashed after unlock was cm10.1 and I got stuck in sideload mode with no hard reset to get me out lol
Otherwise the device is fully functional. For the time being I am back on KA07 xperia revolution rom, with advanced stock kernel (cwm) from DooMLoRD.
If anyone has any suggestions or insight it would be greatly appreciated if you'd drop a comment :good:
EDIT:
I've restored back to 350 with EMMA, but to no avail . It did however tell me that my boot version is : 1264-2309 S1_Boot_Lagan_1.0_2
Is there anyway to change the bootloader :S

After getting home I tried re-locking the bootloader which didn't work.
really starting to wonder if I should be taking it back in as hardware fault.. wonder how that will go since I unlocked the BL

If anyone would be so kind as to do a quick test for me, would you please be able to go into service mode (open dialer type *#*#7378423#*#*) then go into service tests and select the buttons and switches one (I think that's what it's called )
When you hold down the volume up or down button, is it registering as 1 press, or several, continuous presses?
Cheers

Not entirely sure what you are asking, keyboard and switch, volume up only shows as volume up and volume down as just volume down, regardless if you hold it down or press it over and over again, or if you just press it once. Not sure if I am an idiot, but I couldn't work out how to test the keyboard from there.Although one interesting part is that is states it is not a test for the softkeys, but tests them fine

Yeah that was the menu I meant.. couldn't remember lol. Ok so when I would hold down volume up it plays a repetitive tone and the text on screen states "vol up", then "vol up vol up" for the longer I hold it (and the beep/sound keeps replaying... confusing sounding I know
When you hold the volume up botton down, does it just beep once and display vol up (exactly like if you were to press it once and release)?
Basically if I were to press it once, the phone would make a sound and the screen would display "vol up"
If I hold it down however it will register as a new press and the "vol up vol up" texts keeps refreshing as-though it was a new key press.
Also thank you very much for checking it out :victory:

Yep exactly as you say here.
Volume up once shows just volume up beeps once, twice shows volume up twice and beeps twice . Holding it down beeps over and over again and shows volume up twice.
Pressing volume down once from here (volume up volume up) shows volume up volume down, press volume down once more now shows volume down twice.
Hope this helps

Yeah it helps that I can probably assume that my buttons work fine.. I was thinking maybe they weren't registering as long pressed or something but apparently not this is really frustrating. Especially when an app freezes and I just have to sit there indefinitely till it comes back online or the battery goes flat
And I have no idea if it's something I did or something with the phone.
All I know for sure is that brand new it did work as I hard reset a couple times. Then I unlocked the bootloader and have no memory of it working since then... It makes no sense to me why completely returning to stock and relocking the bootloader has no effect though.

Yeah, I could imagine. You will have to find a cool fast battery draining game to help you along .
Not sure that it would be related to you unlocking the boot loader, otherwise I am sure quite a few would have mentioned that before now.
Do you even get the first vibrate confirmation? Have you tested the vibrate from the same service test menu?

That what I'm thinking - can I seriously be the only one having this problem. And why the hell does everything else work perfectly fine lol.
And no I don't get any sort of response (vibration or anything). Normally it just results in the volume turns up then the screen locks or display just times out but even after a minute of holding pwr + vol up nothing happens and the phone is simply in sleep mode. Otherwise vibration works fine.. currently I'm restoring the backup I made of the out of the box stock rom.. that's pretty much the absolute last thing I can think of that might do anything. Trouble is I don't remember if I made the backup before or after unlocking the bootloader.. can't remember if I flashed a custom kernel to get CWM or installed it otherwise...

I would recommend re unlocking the bootloader, the problem is a kernel level driver or hardware but it is definitely around that level.
Did you have any problems, or errors when you first unlocked the bootloader? Maybe Doomlord could give you some of his incredible knowledge on the subject

No the phone is 100% operational outside of the hard reset not working. It is just when I get stuck in a app that freezes or when CWM recovery tricks out and freezes I have to leave the phone for ages till either it a)unfreezes after an hour or so somehow, or b) the battery dies and it shuts off after a couple or more hours.
When your phone is out of action every second day simply cause you can't turn it off it gets pretty annoying haha. If it had a removeable battery I could easily live with it and just rip the batt out no dice.

Stranger still is that I've began to notice that in flash mode the LED briefly flick green once then turns off when entering flash mode. Flash mode is still active, it just appears as though the phone is off :/

Is there other ways to wake up the phone beside the power button?

Hi,
I have a Sony Xperia Z, the power button seems not working properly. May be i dropped the phone and broke some wire connection inside.
So when i press the power button, the button is not working everytime.
Is there way to wake up the phone (when the screen is black) by using the volume button?

^I'm pretty sure that's possible. Just head over to the Play Store and install "Anyunlock".
Although that's just a temporary workaround, so I'd suggest that you get it fixed soon!
