(TMO) TP2 Turns off when screen is closed.

Hi all,
I tried doing a search on this before posting this thread. No luck. I just got my TP2 on sunday. I let it charge and flashed HardSPL and a few roms. I noticed my phone would turn completely off when I open and close the screen. At first, I thought it was the display turning off to save power, but the phone is actually turning completely off and I need to hit the power button and boot it back up again. Is this a setting I need to change? Or could there be something wrong with my phone? I also tried going back to the stock rom to eliminate that as a cause and the same thing happens.
Any help is appreciated.

I have posted an almost similar question here with no reply.

Not sure what the problem is. In my case the solution is not to close the keyboard when OneNote Mobile is still open!

My colleague is having the same prob, from what he is experiencing, i would suggest a hardware fault, probably just a loose ribbon cable... but best send it back to HTC to avoid voiding your warranty

I guess it's time to give TMO a call. Just need to flash everything back to stock.
Thanks for the suggestions guys. I was hoping to avoid having to send it back, but i might as well.

Hi,
I had this issue to and send the phone in for repair. The said that it was a problem with the mainboard - replaced it and send it back. It now works perfect.
REMEMBER!!! If you want to send the TP2 in for repair you must reflash the SPL back to the original one, I think it is 0.79.0000 (see http://forum.xda-developers.com/showthread.php?t=550131 for how to restore to the original HardSPL)

discoverd the same issue, happened to me about a week ago for a few times, when i slide in/out the keyboard. It just habbend about 4 times, but didn't happend again since this time ... i will have a eye on it...

Same here. The screen turns off completely but the phone actually works and I can receive or place calls. Called the HTC support and they advised to try if a hard reset will fix it before sending the phone in. The tricky part here is that this issue can not be recreated easy in their service as it happens randomly with me (sometimes it works fine for days). I am still trying to find out what causes this issue on first place. I think it started right after I installed IGO 8 and changed some power settings in the ini file but it kept doing this after I removed it. I also tried to disable the light sensor (the one that turns the screen off when you place the handset to your ear during a call) because it looks exactly like this - screen turns off but the phone works. So, I will give it another week and I will try the hard reset.
What roms do you guys have this issue with? I am using the stock T-Mobile US with HardSPL.

Sorry, forgot to update this thread. I ended up getting a replacement from TMO. I am much happier now that my phone doesn't turn off whenever I close the screen. Get a replacement while you can and ask them nicely if they can overnight it to you. I did.

Actually, this was a software problem in my case - I did the hard reset 2 weeks ago and since then I have not experienced the issue. I am going to start installing my previous programs one by one to find out what caused the problem.

I have the same problem,
The hard reset solve the problem?

htc desire screen problem

hello. i have bought a desire few days ago. yesterday i notice a problem. i have search the internet but havent find anything similar.
when i press the power button to turn of the screen after i press it again to turn on my screen sometimes the screen turns green and i cant do anything.
this thing doesnt happens all the time. but is preaty annoying and i have to remove the battery.
does anybody have an idea what is the problem

I think it's a hardware failure. Best way is to contact HTC Support.

i am not sure if ita hardware problem. because i notice that moso of the time that this happens is when i lock my screen when an application is open.

I don't think you'll find that's an unusual thing to do! I do it all the time, and have never experienced the problem.
As has already been mentioned, chances are it is a problem with you particular device - especially since you haven't had it for long. However, it could be an app causing the problem, so I'd suggest a factory reset in the first place and see how it performs in a more "vanilla" state.
If it behaves itself, start adding your apps back in again, and hopefully you'll find one causing the problem.
Regards,
Dave

i have already did a factory reset a nothing change. i thing the problem is with the lock screen after i press the power button.. i install no lock now on my phone that disable the lock screen and seems to work ok now.
one thing i forgot to mention is that the problem apear after i did a factory reset.

if this was a hardware problem shouldn't be happening all the time?
i just send an email to htc and inform them with my problem.

Turn it round the other way - if it was a software problem, it would be happening to everyone using the same ROM as you.

yes i know that. but since i disable the lock screen. the problem dissapear.

Today I took my phone to the shop I bought it and after half an hour of trying to show to the guy there what's was the problem. He gave me a replacement.

Hello everybody, i'm fresh new.
Also on my htc desire I have this problem, if you are able to use the device, without see the screen content, you can also shut down the phone. I say shut down because the problem disappear if you stop the phone (or leave the battery) for some minute. it's like all the meroy needs to be lost.
I had this problems some months ago, I unistalled one-by-one the apps, and it worked, now I have installed (during the last 5 months) other apps, and from 3days ago it restarted with this problem.

I am doing but I'm not sure it's the best solution.
I think it is related to some apps, some software problem, but I removed almost all my apps.

I noticed also that if I press the lock/unlock button for some secs, the problem there isn't. But it happen again (most of the time) when I put the device on charge, without turn it off, then when it finished it's a little bit hot and the display doesn't work.
I think it's a problem of the lock button, not software.

what is the name of this app?

I think is a problem related to the memory of the phone. Because I don't have new apps on my Desire.
If I move all my apps on the SD Card, it never (almost) happen...but if some Widget, on the phone, starts in background..
when I push the bottom at the top...the display doesn't switch on.

screen problem
Hi just wondered if anyone else has had this problem bought a desire a few days ago seemed to work fine but it has begun to act a little strange from time to time. from time to time the touch screen will not work just locks up, also the screen goes crazy flipping from one screen to the next, came with android 2.2 but upgraded it to android 2.3 from the HTC official site using HTC sync thought this may stop it, it does not happen as often now but still does it have to turn the phone off then back on again for it to work, anyone got any ideas on this and how I may cure it Thanks for your time.

Does anyone's G-sensor work? i ran the htc function test and it's not working. Any solutions? I've try a factory reset but no joy.

Mine stopped working last night.
When I tried the calibrator it failed saying "calibration aborted" the sensor checker also failed.
I went to the task manager and ended all tasks, I rebooted but no change so I switched off the phone then back on again and all was working
I will have to keep an eye on this

this is indeed a very weird thing mate, it's happening to a lot of people...
I'm sure it's a tegra3 related issue. Probably fixed on the next update.
Now that i think about it...i don't remember to have turnned off my phone when i had that issue...LOL

in conclusion to this subject, my latest "possible" fix is, fully drain your phone out of juice untill it doesn't power up and charge it again.
it should work afterwards.

G-sensor not working
Tried everything I can think off aside from draining the battery flat. Does the 1.28 rom version fix this issue? Seems like my g-sensor has been dead for a while...
Anyone on 1.28 have this g-sensor issue?

I have the same problem. I wrote a mail to HTC in yesterday about the problem and hopes they got an answer for this iritating issue.

Yup. Tried it all and the problem persists. Complete drain, factory reset, secure boot calibration, kill all tasks, ota update to 1.28 (from & to stock), superwiping and flashing a new rom (twice) , running htc's function test and getting "stuck" on the g-sensor test. And more.
Been there, done that.
The sensor doesn't react at all, so rotation won't work and in games like teeter, the ball just sits there no matter how I twist and turn.
And now HTC, via their chat, say that this might not be covered by the warranty since I have unlocked the bootloader. If I turn it in, they'll send it to a service centre, which may decide that the problem was caused by me (which is impossible since it was already there on stock), which would mean that 1) I'd have to pay for any repair or 2) I'd have to pay for "wasting their time" and cough up money for securely shipping it to/from the repair centre. Yay.
On the up side, the normal calibration aborts if I move the phone during the process, which to me would indicate that the sensor is working at SOME level, right?

My question is, was it working when you got it in the first place?
Mine unlocked itself after about 48hours...
The only thing I can remember doing, that I've never said before was that I dropped my phone several times in all possible directions on a very slim carpet as a desperate act...
My thought was, maybe if I drop it and shake it really hard, it might get loose eventually. (Yes I'm a bit crazy... )
It got back to work after 48 painfull hours and lots of failed attempts...

I had this problem, but it was fixed by a reboot. Dont know if that gives you any clues as to whether it is software/hardware related?

Yeah, it looks like some kind of hardware issue. I need to send this phone for repair. HTC has disappointed me - this will be the last HTC phone I purchase. Nothing but problems since day one. Stay people - you have been warned!!!

Actually I'm not quite sure if it worked in the first place, because I bought it used (from a guy who realized he hated Sense after three days). Nothing seems to get it to work, though I'm glad yours did.

Hum... maybe that's why he sold it sorry to hear it mate...
Well, if you are brave enough to do it, do what I did... shake it a lot, and drop it (from low altitude obviously) into a soft carpet... it might sound crazy, but the shaking could be enough to unlock the sensor... corner drop it all around and good luck! going to google it to see if there is any sort of recent found fix...
in the meantime get the app "sensor list" from the market and tell me the brand of your sensors if you can read it.

I had this issue, 3 days after I got the phone. Tried everything I could think of
(fact resets, etc). Still no joy, so I sent it back to the shop.
When they tested it , it was all workign fine again....
However I have a couple of thoughts on this (not tried it out yet so give it a go).
First of all disable that HTC Gestures/3 Finger rubbish. Secondly ensure Fast Boot is off.
Then re-start phone.
Now , Although I did end up like that, I'm sure it didnt fix the problem immediatley following me disabling those options.
All in all there is definatley something screwing up the G-Sensor, which is seemingly fixable/can be disabled. Its just finding out what it is/how you do it!
Slim

I completely agree on you mate. The question is what.
My subconscious is telling me that it has something to do with the live wallpapers but I have no proof. It's just a stupid hunch, but it wouldn't be my first stupid hunch and I was correct so...
anyway, I've just red this...you guys might want to try and do it.

"I just called my vendor, to complain about the auto rotation issue, and here's the step to fix, which worked for me.
Restart the phone, and go to safe mode (restart, and once you see the HTC logo, long press the volume down button), it'll restart again and go into safe mode.
Go to Settings, Display & gestures, G-Sensor Calibration, then calibrate, make sure to put the back of the phone on a level surface, this time, it shows calibration complete not aborted when I did it before in the normal mode.
Restarted the phone and it works fine now.
Thanks,
Mohamed El-Ghazaly"
when in safe mode, I would attempt everything from a "kill all tasks" in device manager to enabling and disabling auto-rotate in display settings.
Good luck guys.

For what its worth I've no issues and have tried to recreate this as I consider whether to return the phone due to screen flicker. Panasonic Gsensor calibrates fine and Elixir gives steady accurate sensor feedback.

[HELP] BSOD

Hi!
My problem is that when I wake up my screen, its black but its responding to input. The screen works when starting the device, but when pressing the power button and then unlocking it like 10 minutes later, the screen stays black. It responds to input, but no picture on the screen. This problem occured today when running IceColdJelly ROM, but I've already run an RUU and are currently on stock, but the problem still exists.
Anybody knows what can cause this?

I remember experiencing the same on a JB preview rom, the only fix would be to hard restart(holding power button for 10+ seconds) and switching it back on.

The problem is I have already done that multiple times. I even run a RUU and are back on stock, but the problem is still there. The phone is totally unusable at the moment. When receiving a call the ringtone starts and it vibrates, but the screen is black and I cant answer.

Oh, well after I went to stock (done because I was sending for repair) I never faced it again.

Hey bro,
I had that issue before and had to exchange my phone. It is a hardware problem and I completely feel your pain since I was in a similar position with the warranty. Lucky me I bought it from a 3rd party vendor.
I believe the only way to get it fixed is replacing or repairing it. I wish you luck and hope it works out fine for you mate

Wait so this issue is the BSOD(blank screen of death?) how come mine went away after relocking and flashing RUU? I always assumed it was the JB rom I was using. And trust me on that rom I faced it at least 3-4 times which got really annoying. And since I anyway had to relock, I decided to go stock. After going stock, I used it for a good 5-7 days and no BSOD.

Yeah, the strange thing is that I can have the screen on for hours. But when putting it to sleep and then waking it up the screen stays black but the buttons on the bottom lights up. I bought it from the carrier 3Sweden so I can only hope that they repair it and not HTC.
And BTW, I'm writing this message from this mobile.

[noob inside] - Screen unlocking problem, faulty device or android bug ?

Hey there guys , I've been searching through the forum topics about my issue but so far I've found nothing close to my scenario.
A few months ago I bought my first HTC phone (M8). Its a great device for sure , despite the fact that I had to return it back twice.
First time it was a faulty microphone , so they sent me back a brand new device. Great isn't it ?
However recently I've noticed a few .... let me call them 'glitches' .
Let me give you some details on what I've experienced with the device:
Despite the issues that i'm going through ... the phone works great, but...
Sometimes the screen wont turn on when I'm receiving incoming calls (same goes for the alarm clock) but the phone is able to recognize touches - i've managed to pick up the call when I swiped the screen in the area where the "green" answer button appears .
The above issue doesnt happen so often but the thing that bothers me is the unlocking issue.
At first I thought that it was stuck or faulty power button.
When the phone is idle for some time and I pick it up and press the unlock button ... nothing seems to happen I've tried pressing it hard ... i've tried pressing it gently ... i've tried pressing it multiple times until the screen wakes up .
Same goes for motion launch unlocking .
When I use motion launch to unlock it the phone only gives me a vibration feedback ... and thats it until I try harder to bring the screen back to ''life'' .
(I can also press my security pattern buttons while the screen is dead and feel the phone vibrating , BUT NOT ALWAYS , sometimes is just .. dead )
I already sent the phone back describing the same problems and they just flashed the firmware , which did not fix any of the issues.
Stock Rom android 5.0.1 , not rooted
Soo what do you guys think? What can I do next .. is it android bug or a faulty unit ?
is it possible to be a sensor problem (proximity , accelerometer)
Already tried factory reset and dalvik cache wipe.
Any advice would be useful.
Thanks for taking your time .
Cheerz

I have the same issue. There are times it takes me hitting the power button 20 times for it to finally light up but I can press buttons with it black. The weird thing is it does it on every single ROM but I havent noticed it on Stock...maybe I'm not using stock enough to see. I'll probably throw stock on there today and take it into sprint and let them replace it.

I have the same problem whether it's on stock or custom ROM (KK or L). I am pretty sure this is a hardware problem. Unfortunately, my m8 is out of warranty so HTC won't fix it for free. I read it some where that it could be a faulty proximity switch so shining a light beam to the top part of the phone may wake up the screen. I haven't tried it yet because every time it happens, I don't have a flash light handy. It is an annoying problem to say the least.
When this happens, I pushed the power button, the volume up button, and swiping the screens. Eventually the screen would wake up and every thing works fine... until the next time.

Its a ****ing pain in the ass.
however none of the sensor reading apps report a faulty/stuck sensor.
the wors thing... I've already sent my phone for repair, describing the problems in details. .. and it took them a whole f*cking month to bring it back to me with no results.
I don't think they will replace it because its a problem that takes time to be experienced...and no one is going to wait for it to happen. ...
Any other ideas?
Should I wait for android 6.0 or should I try a custom rom too see if these problems presist.
Fml I love the phone but this is frustrating.

I have the same problem I think. I just bought an M8 on Ebay. I am S-off, unlocked and rooted, using the Viper Rom currently. I have also tried AICP, the stock Tmobile Rom and a few others. Same issue.
If I double tap, I feel the screen vibrate, but nothing comes on. Then, I keep pushing power button a few times. Sometimes it comes on and sometimes I am too impatient to wait, so I just hold power and volume up.
I also know that the phone internals come on, because after that vibration, I swipe up and push the screen a few times. Then, when I am fiddling with the power button and it does come on, I do see that there is an app already on the screen.
I think this is a rare issue, as I haven't even been able to find many posts regarding this. I may have to get a new one if this keeps going on so bad.

I am experiencing the exact same issue with my M8. I have seen a lot of people stating it may be a hardware fault related to heat and internals but something about how it reacts seems software related.
I really hope someone who has fixed or uncovered the reason comes forward. At this rate I may be switching back to a S4 LTE-A.

I think it IS hardware related. I was able to return that one and got another M8. No problems at all.
