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...

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.

Can't turn the screen on after pressing power button
I have a problem with my Bell Atrix. After pressing power button to lock the screen, i can't wake up the screen up by pressing that button again. Could anyone tell me how to fix it pls.

JASJAR EXPERTS HELP A GUY OUT PLEASE!!!

Thanks for reading the post...I am very frustrated with this device and want to see if ANYONE can help me...
First, the power button...I can turn the device on, but it will not turn the device off...it only lights on the screen backlight or turns the screen backlight off...I can't power it off, no matter how long I press it for...Therefore I have to take tha battery out to power off...which is not good for data!
Second, the backlight on battery level resets itself to 0 (thus a near black screen until I can get it into a bright light and go in and activate the backlight on battery level to 1 at least) Why is this doing this, and it only happens every 5-6 times I power the device on...
Thanks for your help everyone!!!

As far as I know, there is no way to actually power off the JasJar/Universal - it's always in a standby mode unless you pull the battery.
Not sure about your other issue though - sorry.
Cheers,
Steve.

It resets the backlight settings probably because it has "forgotten" your previous settings due to the way you "power off" your Universal. It is a phone, not a laptop, so it only goes into standby mode.

Sounds like you are pressing and holding down the power button for too long. To turn on/off the device, just tap on the power button once and don't hold it down. Hope that helps! :wink:

[Q] Screen not starting up for power button

Hi,
I started to get a weird problem since last week. I've had this phone for about 3 months now and never had any problem like this.
It all started one morning when I wanted to stop phone alarm. The alarm was going off but the screen was black. I pressed the power button to wake up, but it was still black. After couple of times pressing the power button the screen came up. First it was not that often but the situation started to get worse. It came to that I can sometimes cannot turn it on for a long period of time. I need to keep pressing power button, volume buttons and eventually it will come up.
This is what I've found so far:
1) When the power button is pressed, although the screen doesn't start up, I can see the three buttons at the bottom lighting up. So it is not a problem of the power button.
2) When the power button is pressed, although the screen doesn't power up, the screen seems responsive. I can feel the vibrations when I tap (I have a startup password)
3) When the phone is connected to a power supply, screen always starts up without a problem.
4) Screen will start up more frequently when the batter power is high.
It seems as though there is a connection between batters power and the screen not starting up. But then again, once the screen comes up (after not starting up), then it works fine, until I turn the screen off.
Has anybody experienced anything like this before?
I did a factory reset thinking it might be some application I installed but it didnt help.
I had to send this phone once to repair the speaker and cost more than $80 just for courier. I don't want to spend another to get this fixed.
Thanks.

I have this problem or a problem very close to this. I have a HTC One X (international version). I'm running the latest version and updates and the problem has existed for at least the last two updates.
Android Version 4.1.1
HTC Sense version 4+
Software number 3.18.401.1
I have the screen lock pattern turned on.
Sometimes when I hit the power button, the phone does not turn on and so I press it again and only after a third press does the phone turn on. I then unlock the phone and use as normal. So, several times per day I have to press the power button three times before the phone turns on. But other times I press the power button once and it turns on straight away. I've just turned the pattern unlock off to see if this makes any difference. I'll start to record the exact details of when I experience this and see if we can work out a common cause.
Hopefully if enough people report this problem then they can send out an update to fix this problem.

I'm pretty sure this is a hardware issue. I bought mine from Expansys and sent it back to them for repair. It's been more than a month and they say they're still reparing it.
In my case it was impossible for me to start the screen up with power button no matter how much I pressed it. The only thing that worked for me was to press the back of the phone just below the camera. So it seems like a hardware issue. But on the other hand, at times when I can't get the screen turned on no matter what I do, I'd turn the phone off and start again and the thing would start up like nothing happened. So while I'm pretty sure it is a HW issue, I'm not sure how a power restart makes it work.

For me I don't think that this is a hardware problem as it only started happening once I did the big upgrade from 4.0 to 4.1 and then it follows a specific pattern. That is three power button presses will always turn it on. Less frequently I also get a problem where the power button turns on the three lights on the soft buttons but the screen remains black. I then hit the power button to turn it off, and again to turn it on and the phone is back to normal again.
Is yours an international version? I bought mine an international version and had it shipped to Australia.

solved?
Hi - did anyone ever solve this? This is happening to me with my HTC desire X after having had the screen repaired, so I think it is hardware related, but the shop doesn't know how to fix it! My screen also does not turn back on when I want to end a phone call and pull the phone away from my face anymore. These problems seem related as they started at the same time. I would be grateful for help!

Major Catch 22 - Desire got Wet now have 3 issues! PLEASE HELP

Hi guys.
So i managed to get my desire wet/damp and whilst it still works it has developed 3 issues:
1) The weirdest of all - the phone wont go into standby, as soon as you press the power button or let it timeout the screen goes off and they instantly turns back on to the lock screen. If i leave it, it will timeout again on lockscreen and come back on, it does this forever. I have done factory resets etc, all the same. Weird right. As i result i would like to reflash the mod and see if that fixed it as assuming its software related (somehow).
2) Volume keys do not work - think means i had issues getting into recovery. Finally found a widget to do it and then....
3) Trackpad does not work in recovery so i cannot re-flash or try any new rom to see if that fixed (1)
Proper catch 22
Any suggestions appreciated.
Thanks

Install 4ext touch recovery.

Update after installing touch recovery
OK I HAVE AN UPDATE:
The plot thickens but i have managed to S-OFF my Desire and eventually install Clockworkmod Touch which obviously doesn't require me to use the trackpad button so I was able to use Recovery. I wiped the phone and tried reflashing the ROM i had been using (Insertcoin) but this made no difference, the phone still keeps waking up immediately that it goes to sleep (either with power button or by sleeping timeout).
So i decided to install a completely different ROM (CM10_VJ_4.1.2_v3.0) and this installed fine. Now the phone will go to sleep and stay asleep if I press the power button. Problem solved I thought!
Now when the phone is asleep 50% of the time, trying to wake it with the power button will cause it to reset immediately and goto the white HTC screen. When it restarted it sits on the unlock screen and keeps timing out, screen goes off, then immediately on again - weird. If i unlock and lock with power button it will behave. For some reason the Search key will wake the phone every time no issues. Only the power key to unlock causes it to reset. Phone is sleeping according to Battery info.
Any other suggestions for what I could try. Could this possibly be something hardware related now? If there a way i can log the key presses or reason it wakes/resets?
Any help really appreciated, the phone is pretty unusable with this reset issue now.
THanks

theres a few videos on youtube, if it was me i would take the phone apart and clean all round the buttons. mite solve it. But as it got wet, the water could of damaged something in around the trackpad r power button, hense always waking the phone.

Thanks mate. So i tried this and installed CM7 today and have discovered something. As i said above the volume down button doesn't work and the volume up only works with some persuasion. Once i installed CM7 the problem where I lock phone with power key and it instantly wakes up now persists (on the JB rom it at least stayed asleep but reset if power button was pressed again).
However whe i changed the display timeout to 15seconds i watched as it timed out and instantly woke then noticed the volume would increment down one notch each it woke up again. This leads me to think that rather then the volume down not working at all it is actually stuck down permanently and could be causing the issue here. Is there any way I can find out if this is the case and disable the volume keys through software or do i need to open up the phone and disconnect it?
Thanks for any help - i think we are getting there!
Bridgstfer

I actually worked out that the trackpad is being pressed down constantly too because on CM7 when i disable trackpad to wake the phone actually stays asleep. Stil the phone resets if i try to wake with power button though, must be something to do with the button combo being held down.
Is there any way to disable both volume and trackpad buttons at the kernal/system level?
Tried button remapper but does not allow to remap the trackpad press.

With a file explorer, go to
system>usr>keylayout and modify bravo-keypad.kl.

I'm just back from holiday where my Desire had a ten-minute swim in sea water!
Naturally it was stone dead when I remembered it was in my pocket as I waded across an inlet which was supposed to be ankle- deep but was over 1.5 metres in places
I thought there was no point in drying it out without first removing all salt so (minus battery and cards) held it under a tap for several minutes then left it to soak in tap water in the sink for 30 minutes.
I then dried it over gentle heat for a few days then tried the battery. The vibrator ran continually and the white LED flashed randomly but nothing else. After another two days drying it booted - but only into Fastboot and the vol switch didn't move the cursor. But after another two days - it worked almost perfectly! The vibrator is dead and the screen a bit streaky, but all the other sensors work just fine and it's quite useable.
I had been logging the hike using My Tracks and it actually shows the course going a short way into the sea.

do you have an assurance or warranty?
if yes-->change phone.

Thanks for this. I actually got an app that let you remap the keys but it does not let you do anything to the trackpad click button (which is now the one stuck down). See photo of whats in my bravo-keypad.kl file here:

Any other way i can disable the trackpad completely. Perhaps at the kernel level?
Thanks

Weird problem with screen/power button

Background -
I bought this OnePlus 5T with a smashed screen to fix.
Paid 70 bucks for it plus the screen is just shy of 150 in total.
I was able to replace the screen and frame which was a little more complicated than I anticipated, but it ended well and the phone seems fine, although the screen quality isn't as good as stock.
***Problem - it seems that for unknown reasons, after turning off the screen pressing using the power button, screen becomes black and won't turn on, not until i hold the power button for ten seconds and restart the phone the hard way. Then the phone turns on and starts working again, but if I turn the phone off with the power button then it won't turn on again. I can tell the phone is working behind the black screen, vibration working, notification light working. But Everytime I turn the phone off with the power button I have to hard reboot the phone to get it back on again. Once this starts happening I have to factory reset to get the power button functioning normally again. It will work normally for a day or two and then out of no where the issue comes back again after pressing the power button - screen won't turn on.
Could it be software? I know it might be natural to suspect the screen is faulty, but the screen works normally until I use the power button to turn it off, and then works normally again for a couple of days after a factory reset ...
Thoughts ?
