[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

[Q] Boot loop with a difference...

Took my phone out of my jacket pocket earlier since I thought I could hear a weird buzzing noise every ~8seconds. Looked at my phone and can see it's stuck in a boot loop. I can't hold the power button to turn it off it gets as far as the HTC screen and then goes black. I've tried to get into recovery mode (just holding down the volume - button). It does work to get in there but I only have ~8 seconds before it goes black and reboots again, doesn't seem to be able to pic any of the different options in there though (with - or +)
This phone is stock O2 (EIRE) never been touched not even rooted. Anyone have seen these issues with HTC One X? :crying:
Is there any recommendations that I can do? (key combo) Hoping that when the battery dies it'll go away... doesn't feel to stable though!

I have an idea ...... turn it in for warranty right away

anything to try first?

Hi,
Try this:
Hold power button together with volume down simultaneously till the phone reboots. Still holding both buttons you should go to service menu. Then choose bootloader with using volume key down/up and when the bootloader is selected press once power button. You should go to bootloader menu, from which you select power off and press power menu.
Your phone should be power off.
Then try to press again power and volume down buttons till you gonna gain in service menu. From there you should find and select factory reset and press power button once.
Your phone should be resented and then just reboot.
If everything is correct your phone will be with everything reserved and also your data and settings will be gone, but at least will work. Then you should set again your settings and preferences.
Hope this could help to get your mobile working again.

Thanks dude, that almost worked... got a bit further after factory reset... went to the O2 splash logo and then back to beginning... actually tried it again before hitting reply, wanted to make sure that I actually had time to hit the factory reset before the phone rebooted (8seconds, less actually seems to be 2-3 seconds then a bit longer after...)
I've got a feeling the phone is/has overheated and resetting itself. I think it's rubbish you can't take the battery our of these!

Finally stopped rebooting, battery must be knackered. Will leave it for a while and then start a charge, think it's going into an O2 outlet Monday!

As soon as I started charging the phone booted up and back to loop...

Sorry mate ...like i said, warranty case

Power Button unresponse (stuck?)

Hello,
My HTC One M8 power button suddenly went unresponsive yesterday - Nothing happens when i click it to turn on/off the screen or even get the power menu up. Sometimes it seems to be stuck (Pressing the home button triggers the screenshot function (Power + home ))
The button itself does not seem stuck or anything and i get normal response when clicking it hardware wise.
I already tried restarting which didnt solve the problem.
I'm running stock rom, unrooted version 2.22.401.5
Any idea what might wrong?

My PC currently suffers from the same button stuck issue. All I do is power it off and keep pressing the power button something like 20 times gently and continuously. Give it a shot. Make sure the button is clean in the cut outs and do the same trick to your button. Make sure you [DONT] power off the device, as there's a chance of never booting up; just some friendly advice. :good:

Sorry to bump this, but might be helpful if anyone else gets the same problem.
I sent my HTC One M8 to repair where they replaced the power button - Everything seems fine now.

[Q] Sumsung Galaxy Tab S 10.5 (SM-T805) screen went black

My tablet Galaxy Tab S 10.5 (SM-T805) screen went black. I can’t see the screen.
Touch also does not seem to work. However it’s on. it is receiving calls and other messages. It is connected to WiFi.
Power button, volume button are working but I can’t power off the device cause I can’t see the screen options.
When I plug in to the charging cable it vibrates but does not show anything on screen.
It didn’t drop and hit by anything…i have been using it for 3 months now. it just happened by itself or may be by some update that I don’t know.
Please help how to bring it back to life

Are you able to get into download or recovery? I've never heard of something like this before. Maybe go ahead and let it die and then plug it back in and see if you can get into download mode by holding home+power+volume down then re flash your stock firmware or whatever you were using. Or do home+power+volume up to get into recovery. If you still have stock recovery then you can just do a factory reset right from that but if your using something TWRP then your still going to need to flash something after wiping your data.
Not sure how else you can get it to shut off since you can't see it. Even knowing where the power menu is once you press the button it would still be tough to hit the right thing. I'd say let it die. Maybe someone else can come shed some light. Of course it could be a hardware problem as well. I'm leaning toward software still though.
If your still completely stock I'd say let it die and get into stock recovery. Home+power+volume up and then wipe data and do a factory reset. Now if the screen stays black after its off and you've plugged in the charging cable then I'd imagine there's a more a serious problem going on.

Yes I am waiting for battery to be completely drained out. I will try your method once the battery is completely dead.
thanks

Your welcome let me know how it goes. Will do my best to help.

I don't have my tab with me right now but can't you hold power button for 10 sec to force a reboot? All Android device I ever had could do that.

Doest work on t805 holding powerbutton, just hold the buttons for download mode and that will force it to reset and prompt you to press volume down to cancel volume up to continue...hold for 30 seconds, and if nothing appears let go and just press volume up once, still no joy then pop back cover off and unclip and reclip battery if your brave, thats what i did before i new about this quicker way.

How to run the battery completely down..? its still active and on... though not showing anything on screen.
Is there any quicker way... ?

To do a hard-reset on these Samsung devices, you need to hold Power + Home + Volume Down until it reboots. On every other device it's just Power. Some it's Power+Home. For some reason Samsung likes to be different.
Or if you have previously enabled USB Debugging, you can plug it in to your computer and do an ADB Reboot.

Power + volume down + volume up works for me as reset.

Holy crap the dude is right....just tried that myself on t805, holding all 3 buttons at same time in top left corner power,vol dwn, vol, up forces a simple reset without dwnload mode rubbish.
