[Q] Black screen on HTC Desire

Hi guys
i have a strange issue on my device,since stock ROM i guess, the problem is follows:
my screen just go black sometimes i thing it happend only when a call is in progress or when call is ended by the third part, the screen just stay black and no solution but uplug battery and start up the phone
i had this problem eaven on my stock Rom froyo 2.2, then i try leedroid 2.3 and it was ok i guess, then i try oxygen rc6 everything works superb,fast,clean,smooth but the black screen occures multiple times in one day (today around 3 times) so i was forced to return to my stock froyo 2.2 and hopes will be ok,
the problem is as i search thru internet... seems like one of the sensors works baddly, i think is the proximity sensor, what can i do? should i sent my device to repair? i realy appriciate any help and suggestions and ideas how can fix this problem....

still no solution it happens on stock froyo 2.2 too but in smaller period as on oxygen rc6, i try set --- display off to value 30 minute from previously 2 minutes and problem dont occured for last 2 days

this might seem like an ovbious answer but when your making a call the desire has a light/proximity sensor to the left of the top htc logo that turns the screen black when it senses something, this is to stop you pushing buttons with your ear.
i dont mean to insult your intelligence or anything, just saying ya know if it happens when not in a call it sounds like a software issue

i already know that, searchin a lot about this problem mate trust me, i also know when the proximity sensor is located and what is his function but the issue happening only when a call is made never happend just like that so i thing no sw prob, using stock froyo 2.2 now no root just a clean official and it happens like 2 times per day when i was calling more that 2 minutes when i set in setting--display to turn off screen in 10 minutes this problem dont show up soo i dont know realy maybe i sent my device to reklamation will see

This happens me with root and without root. It's when your using anything that has with the SD card to do with. Like the gallery, it has gone black for me to under a call though... I dont know how to fix this problem, and it's very frustrating to take out the battery all the time.

My friend i am working in mobiles but i couldn't guess the problem cause i bought my cousin this HTC desire until she removed the screen guard (( the plastic sticker for protect the screen)) from the screen and i solved the problem so easily.
Best of luck

true is that i am using Zagg shield, but this cannot solve the problem cuz i try few days without any screen protector and the problem was still there,
but i guess i solve this problem few months ago, i notice that the black screen after call happend when my network is set to "GSM only" strange but since i use WCDMA only the problem is gone, dont know surely but guessing, also when i use mobile network in gsm only mod, phone freezes totaly and only unplug battery helps, as i said since i am using wcdma/hsdpa/3g only non of these strange thing happens
hope this help for someone

Hi, guy!!
I've the same problem several months ago. Have you solved by using WCDMA only??
Thanks

Hi all,
This was happen to me last few day and i google whole world, finally i find my answer and i hope it was help for those who facing this kind of problem.
I can confirm this problem no related to rooted or without rooted phone. this problem definitely come from the proximity sensor which people highlighted this sensor located at top left of htc logo which u can see a blue color circle there.
Try watch this video of disassemble htc desire and you will find the way to clean this proximity sensor area.
Tools to use for dis-assembly:
1. Philips screw driver.
2. Torx screw driver
Cleaning tools:
1. a wet small cotton buds.
Hope this method can help.
Area to clean:
1. The proximity sensor which you will see covered by a black rubber
2. The casing area which i show on photo.

[Q] Screen is dark suddenly having to restart

First excuse my English.
I'm here to report something that is happening on my nexus recently.
When I'm using it for a while the screen goes dark having to remove the battery and put again return to normal .
I see that it works normally when the screen is dark, because if I touch the screen it vibrates and performs what is on the screen, but do not understand why she is erasing out frequently, I've used other roms and kernels but it happens even be that the problem is on my player or someone besides me is having the same?
How to solve?

Generally a Kernel Issue. Which Kernel are you using? I had this problem before until I switched kernels and presto. Problem resolved.

[Q] Screen Won't Come Back On After Call

I have the Chinese version of the Find 7 currently running MoKee 44.4 because I thought this issue was caused by AOSPA, which I flashed for the first time yesterday. Anyway when I make a call the screen turns off as it should and will not come back on no matter what I do. I have to reboot the phone every time. I looked through similar threads but they all seem to be unrelated to having a custom rom; this problem only started occurring after I flashed one & everything worked fine when I was running Color OS 2.0. I tried installing a new dialer but the same problem happened.
Does anyone know of a way not to have the screen turn off when making a call or better yet how to fix the issue?
Thanks very much!

I'm having a very similar situation with Paranoid Android 4.6 (both beta4 and latest beta6).
If I long-press home button, I'm sent back to the lock screen, but only after the call is finished.
Maybe there's a problem with AOSPA's proximity sensor during calls?
Sometimes, the screen will not turn off, but the screen will not react to any touch input during the call.
Power button will turn screen off but not back on again.

This is a problem coming from ColorOS 2.0.x.
I will try to flash back to and older version of ColorOS. After that try an AOSP rom.

Whit all rom use CM11 based or similar, I have black screen when I call, and no input possible!
