[Q] Lock Screen Remains Black on Unlock - Desire HD Q&A, Help & Troubleshooting

This is a problem that seems to be getting worse and worse for me.
I'm running the stock ROM from HTC on my Desire HD.
When the phone goes to lock and and I press the power button to unlock it, 95% of the time the screen does not come on.
The touch screen is still enabled however, as I can unlock by swiping and make the phone vibrate by pressing the home key, and the back light does come on and off every time I press the power button. But the screen just doesn't come on.
I've read that the DHD has had a lot of problems with the proximity sensor, but I'm not sure that that is my problem as the back light comes on and the touch screen can still be operated blindly.
Any suggestions as to how I might fix it?

Seems to be a hardware issue from the looks of it. Rooted? Which stock firmware?
I bought the xda app. Problem?

If you are s on then there are two things you can try. First I would clear app cache, turn of fastboot and re boot phone. If problem persists then re install ruu.
If you are s off go into recovery and wipe cache and dalvik and see if that works. If not do a backup of your downloaded apps and re install ruu.

Just wanted to check, does your screen come on as normal when you enter hboot?

Thanks for helping out.
the hboot screen has the same intermittent problems as the phone normally does. If I turn it off with the screen working, the hboot screen will probably come on. Though there has been one instance where I was in hboot with the screen not working.
I'm going to try wiping the cache (I'm still s-on) and turning off fastboot.
Here's more details about the phone itself:
Kernel Version:
2.6.35 10-g931a37e
Build Number:
3.13.161.3
Android Version:
2.3.5
I really hope its just a software problem I can sort out myself. Hate sending my phone off the HTC.

Yeah I would try software first. Though since you say it happens in hboot as well it is most likely a hardware issue. Probably not what you want to hear.

Camera causes reboot?

As titled, anyone else?
I am surprised tht all the other reboot problem is from overheat because my desire doesn't get hot at all...
As for my desire, not rooted, definitly not caused by apps because i specifically tried to use the stock rom (unbranded) and it still exist...
It happens when i start up camera, te screen will turn black and if i press power button quickly enough, it will turn screen off as usual, when is unlocked, it will go back to the home screen. If i leave the black screen for a second or not, it will reboot my phone (soft reboot)
Problem only occurs sometimes, no symptoms that show if the camera will cause reboot or not.

First off, this has nothing to do with android development, it belongs in the Q&A section.
Secondly, you can get into recovery without your touch screen just fine. While your phone is off, hold vol down + power, which will bring you into hboot. Use vol down to highlight recovery, and then press power to select it.
If you do not have s-off, you will see a screen with a !. Press vol up + power, and flash update.zip (assuming you have clockwork update.zip on the root of your sd card), and then proceed to reflash your rom.
If you do have s-off, the hboot recovery option should take you straight into recovery.
WTF I have the same problem! It just ramdomly started yesterday, I touchscreem wouldn't work on opened keyboad and today afternoon I was typing something, after I closed the keyboard the touch screen doesn't work anymore!!!

This should be moved to another thread, Nothing to do with Android development
Ok DO NOT RE-FLASH A NEW ROM if your are in this situation!!!!
because I tried it and still touch planel doesn't work and I was stuck at the setup!!, thank God I recently saved a Nandroid backup, but when i went to ClockworkMod the optical track pad is no longer working neighter!!!
so I couldn't select anything!
I went to cmd on my PC and did adb shell then nandroid restore {location in sdcard}
it restored oh yes!
Optical Track Pad aiin't working neighter touch panel, like this i can hardly make calls with the keyboard, launch apps, but can't handle things that require touch or optical pad.... I can only use Tab button and enter to do little.
Fu...I need to revert everything back to stock adn get my waranty replacement..
why this had to happen?? I haven't done anything these past week :S
This happened to me also I posted my thread in q&a i believe tho, anyways tho my power button stopped working so i couldn't get into recovery. If you need a way to get back to stock without touch screen use the esprimg.zip from the factory rom champion build thread just search for it on xda. after going stock mine was still not working but I was atleast able to do a warranty exchange. hope this helps at all. Oh also this happened to me soon after flashing to CM7.
The same happend to mine a few months ago, your flex ribbon has torn, you have to send it into T-Mobile for an exchange!
Also, wrong forum

Not sure if its the same issue or not. But my screen will become unresponsive and soon after which ever launcher I am using will crash. Also using CM7. Was running nightly build before. Hmmm strange all of a sudden several of our phones started crashing..
You can still slide open and use the physical keyboard to select things...however I would get the stock esprimg on your device as soon as possible. Your ribbon could tear even more and leave you with a black screen and no luck of getting a replacement if you are with a custom rom.

The last thing I did before I also experienced this, was that I tried to get S-Off and couldn't make it, rebooted but everything was fine, and before that I had gave a try to CynogenMod 7.... Days later I was experiencing 20kbps download and later the touch panel failed also the optical pad, so I unrooted before it'd get worst, I got my warranty replacement and now I better send the damaged one back before 7 days, otherwise they charge me $200.

[Q] Lock screen keeps re-appearing!

Hi all
My lock screen is going crazy. Every time I lock the phone, and the screen goes off, it immediately comes back on again - just like I've pressed the power button. It's very odd. The phone actually reboots if I press the power button a couple of times.
Any suggestions? I've even reinstalled the rom bit it's still happening.
I've checked the timeout and it's set to 30 seconds. Also there are no apps running and no animated wallpaper. There is no issue with the power button - the phone works fine apart from this.
I'm running CM7 on my HTC Desire. Any advice would be appreciated.
Thanks
Jonny
Do a backup then wipe. Still happens?

Yes still happens. ALso installed a new rom from scratch. Still happens!
Very bizarre. Incidentally my down-volume button on the rocker no longer works. And reboots are more frequent, mostly when the phone has been locked for a few seconds and I press the power button...
I've screwed about with it a lot over the year so I think I'd like to unroot and install stock HTC rom again. I'd like to give it to my Dad when I get my galaxy nexus anyway.
Are there any instructions/steps available detailing how to unroot and put back to the factory rom?
Thanks again for all your help.
Jonny
I dont think that will fix it. Sounds like a hardware issue on the motherboard. Perhaps water damage...
But yes, search for RUU to return to stock. You can use the GB 2.3.3 one from HTCDev.com
Having read your first post I thought it was the accelometer that might be faulty, but now I'm not sure. As the previous user said it may be water damage.
To remove root, just install the latest official RUU. Normally found in the Android Dev Forums

Periodical unlocking problem

Hi,
I'm a new member here. This is also my first android phone I ever had. I've searched if someone already has similar problem, but I didn't find any thread with the explanation so I decided to make a new thread.
Here is the situation:
I have Wildfire S, system is updated to android 2.3.5 ; software number 2.26.169.1
My problem is unlocking. Sometimes, when I press unlocking (power) button at the top of the phone light doesn't appear on the screen (only sensor buttons are lighten at that moment). After that I put my finger where ring lock should be shown and slide my finger up, and the phone unlocks... After pressing the power button at the top of the phone I should be able to see my screen (it should turn on), but that doesn't happen every time. I tried with restarting the phone. After restarting it works fine, but the same thing happens again lately.
Phone came with android 2.3.3. To solve the problem, I tried factory reset after the upload to 2.3.5 (thought it is going to return system to 2.3.3) but software version stayed on 2.3.5
If anyone knows how this could be solved, please tell me.
Thanks!

Are you running a custom rom, if you are, then i suggest you set your min frequency at about 200mhz. If you are using stock, unrooted, i suggest you take it to the HTC service center to get it fixed or better still, root it and enjoy the limitless possibilities of android! :good:
Thanks

Thanks for the replay. It is stock ROM. As I said I recently started using android. I'm not familiar with all of that possibilities it has. I'll consider what to do. Anyway thanks a lot!
In addition to your above mentioned problem I also had problems with the unlock screen. Sometimes it doesn't unlock easily and I hav to pull the ring 4 or five times to unlock it

Power Button/Restarting issue

4.0.4
CM9 alpha 6
Yesterday my phone just started rebooting randomly in a loop, it would get to the launcher and boot up completely but would just automatically reboot, as soon as i would the put the battery in the phone would turn on without even touching the power button, i was able to get into recovery and wipe/reflash my rom and that seemed to fix it but then my power button stopped working and the rebooting issue returned, i wiped and reflashed etc and did this twice and now i'm stable but i'm afraid the issue will return.
What is the issue?
What/how should i update to a new rom?
bump, help!

how do i even check for defect? i saw the other thread where some guy posted a picture but i couldn't even tell what he had done
Only way I could see you trouble shooting that is by taking it apart. If you do be careful with the screen

Keep in mind that this is a hardware issue and changing roms is unlikely to fix it. Unfortunately, if you can't fix it yourself you're going to have to shell out $35 on a repair or just have to deal with it.
who does the repairs? regular sprint stores?
