[Q] My lockscreen and power menu is gone - T-Mobile Samsung Galaxy S II SGH-T989

So I was using the hardware test on my T-Mobile SGS2 by dialing *#0*# and I tried the sleep mode test. After quitting the hardware test, I realized that when I press the power button when my screen shut off, I don't see the lock screen anymore. It jumps right to the home screen. Also, when I hold the power button down, I don't get the power menu, instead, the phone shuts off. I feel like the phone is still in the hardware testing mode, at least for the sleep mode. Any clue on how to fix this?
Edit: I did notice that every time I restart my my phone, the factory test service starts running.

Bad move. I believe the only way to fix this is factory reset....

Unfortunately that's the only solution I see to this.

Power button problem

Hi all,
My XDA IIs works well before. But few days ago the Power button doesnt work properly, it can turn on the phone, hold to turn off the back light, but I can't use it to turn my phone screen off like before. Anyone has same problem ?
Can you see any part of the screen? It might just be that the backlight adjustments are set too low when the unit isn't cradled. You might be able to see the screen in daylight.. or maybe it was inside your home. I forgot where I was at when it happened to me. In anycase, if you can see a bit of images on your screen, go into the Backlight properties and change the setting to your liking.
Good luck..
The problem is i can just press the power button to turn off my phone BEFORE (the screen is completly off), and NOW it doesnt work at all ! When my phone was off, I can press the Power button to turn it on, or when I hold it for few seconds the back light will be turned off, but press once to turn off. I dont know why, if somthing wrong with the Power button it should be doesnt work at all, that's mean i cannot turn on my phone as well. But other functions of the Power button are still work well, except the 'Turn off' :roll:
power off doesn't work anymore
I have the same problem here. I can't use the power button to power off my qtek 9090!!
i can use the power button to turn my pda on and to switch the background light on and off - so the "hardware side" of the power button is working.
however, i can't use the power button to turn off the device. it's very annoying, because i can't put it in my pocket after finishing a call :-(
this should be some sort of a software problem - so i hard resetted my device (a couple of times) - but that didn't help!
can anyone help?
thanks,
lorenz
the ba doesn't turn off it is always on staand by mode. ->settings -> system -> button lock
this will stop any missed call because when the ba is in standby the power button is the only one to work
power on is no problem. i can't put my BA into standby mode. if i press the power button while the BA is turned on, nothing will happen. the screen will stay on, the background light stays on.
i have no way to put it into stand-by with the power button!
try this and see if it works. it's a software app that wil rest, shut down, and turn the screen off. just copy it to your BA temp directory and install it.

power button problem
Does anyone solve the problem???
Had the same problem...
I had the same problem going on for about two weeks or so...never changed anything and it went away all by itself.
The problem has not come back now in over 4 months.
Sure would love to know what the problem was tho...
Greetings,

Power Off does not work
Add my name to people with this problem.
The only event I can link it to is this: I deleted my Motorola Bluetooth headset and installed a Logitech headset. I noticed the problem (can't turn OFF with POWER BUTTON) soon after that.
same problem for me ..... someone must know !!!!
I think it is a hardware problem. The contact is not making cleanly. Disassemble and spray time, perhaps.
It's a standard push switch, easy enough to replace, I occasionally list themon ebay but any phone repairier should have them in stock.

i had same problem yesterday afternoon, but it is ok now. recovered by himself
Write again in two weeks and let us know if it is still healthy. In my case, anintermittent problem became continuous.

[Q] power button issue?

Hi all,
does anyone sometimes have to press the power button (when phone is completely turned off) twice (2 presses to turn on) sometimes?...
so just to confirm
- handset is off
- push power button once (sometimes doesnt come on
- push for second time (and powers up)
im defiantly pushing for long enough
iv have no issues with the button at all when in the UI or when locking/unlocking display
iv done a few tests where i have turned off. then went to switch on, with the same pressure and sometimes it starts with one, sometimes it starts with two presses,
do u think this is a fault? anyone experience this? normal?
just checking...
thanks heaps!
I had the opposite on my first one. When I pressed the power button to turn screen off, the screen went black for 1 sec and jumped back on lock screen.

I don't think many people would turn their phone completely off so haven't found the issue.
When you power off what will be happening is the phone is off as much as it can be, but these buttons are soft off, the battery is still connected and some power must be drawn to run the power circuitry to detect the button being pressed again to signal to power back up the phone, in the same way when you turn your TV off by the remote, power is still drawn to run the remote sensor on the TV.
To keep the drain on the battery as low as possible so the battery isn't completely discharged over months of storage I suspect the power chip waiting for the on signal again is only sampling every so often to save power so it can be in super deep sleep state. This means depending on where in this cycle you are when you press the power button it might seem like it isn't responding, so typically you have to leave it depressed long enough for it to be "seen".
The better option is to just to put your phone into flight mode if you don't want to be disturbed or want the phone off. I do this overnight and lose no battery power by the morning, so it is as good as off. You can add a button to your home screen to do this quickly, widgets are included already for that.

Phil
Mine does the same thing.. Sometimes it does it with waking up from sleep also.

Powerbutton

Seems like I have a problem with my power button.
It seems to be depressed all the time.
Can not turn off / lock the screen, nor unlock.
After I took the battery out and put it back in turn on the phone by itself.
If I go into the boot, I can not use the volume keys to change choices.
I restart in recovery so I can go up / down the menu using the volume buttons, but do not make any choice with power button.
Is it hardware failure?
Anybody had similar problems?

Had the exact same issue on my Nexus S. 100% the same. I was also unable to re lock my boot loader cause of it due to being unable to flash, navigate or use adb due to the button being "pressed" all the time. Brought it to Samsung and they replaced the button sensor. It was 100% hardware as yours is too if your phone boots when you put the battery in (before the os even boots). Warranty time my friend. Samsung makes awesome phones with **** power buttons

S3 stopped booting completely

Got a problem. My S3 won't boot up. I'm running AOKP, not sure which version.
When I pull the battery and put it back in, the Samsung logo flashes once, like it's trying to boot, without me ever touching the power button, then it goes black. I went to the cell phone store and tried with another battery. Same result.
I've been having problems with the power button sticking internally recently. No evidence of sticking from the outside, but the power menu randomly appears, and the phone would randomly shut off. I don't have a lock on my phone, so I overused the power button a lot.
Is it supposed to turn on like that after you pop in a fully working battery, or does that mean the power button is being held in place? Could someone confirm what happens if the power button on the S3 is held down continuously after you turn it on?
Also might be a software or flash problem from too many random reboots.
Hopefully the motherboard is not toast.
It's likely that you are just having a stuck power button. Normally if you just hold it down, first the power menu will appear and if you continue to hold it down, the phone will go black and try to restart.

How can I fix this?

Power button sometimes takes me to lock screen?

Sometimes when I press my power button, wanting to power off the display, I instead get the lock screen. Has anyone else noticed this?
Start position is just the home screen.
Found another thread with similar issue but in that case it's a HTC EVO.

Is it possible that the power button is registering 2 presses, instead of 1?
What if you start with the phone turned off, then press the power button? Does it turn on, then off again?
I'm never able to reproduce it at will but I suspect you are right.
Sometimes the press on the power button isn't registered at all so I suspect it's a hardware issue.
Have noticed it since day one and I have had the phone for a month now.

Got it back from LG authorized service center now. New power button and new camera glass (that was another issue I had).
All OK, it was a hardware issue!
