Rooting triggered proximity sensor issue?

Hi all,
I recently received a replacement Desire for my 'faulty' one. I tested all basic functions before walking away and everything checked out.
After I rooted it and installed Modaco r17 ROM, My proximity sensor sensitivity dropped dramatically. When I make or receive a call, the screen blanks as it should, but when I move the phone away from my face, it stays blank. I can't end the call or use speakerphone or keypad. The only way to bring the screen back is to hold it under a very bright indoor light, or direct sunlight...or pull the battery, of course.
I loaded a sensor test tool (SensorList) and it confirms that the sensor is reacting only to very bright light. I've checked that my cover doesn't obscure the sensor and tested that the behavior is the same with or without the screen protector.
I tried a couple of other ROMs, Modaco r19 and Shadowfrost v13. I un-rooted my phone and dropped a stock HTC ROM back onto it...and the problem is still there!
I'm waiting on a reply from HTC service about it...but in the meantime...any advice? I've seen a few posts around the web with this problem, but no definitive solutions or answers.
Question Added to Developers
I've noticed a smattering of people in various forums, with various of the newer android phones having proximity sensor problems. Perhaps these are not quite as finely calibrated as the other sensors, or not as reliable. Have any of you developers seen a way calibrating or adjusting the sensitivity? Perhaps a value in a system file we can change?
Thanks in advance.

Added question and bumped
Apols if this is pushy. I added a question to you developers, so giving this a bump.

FYI:
Proximity and Light sensor does not work with Sensor List in a Froyo ROM. Tested it myself just now.

Images:
1. Holding hand over phone screen
2. Clear view of the screen in dimly lit room (it's quite cloudy )
3. While running FroYo
This does seem like Sensor List correctly detects and measures the proximity/light sensors in FroYo on an HTC Desire, or am I mistaken?

Ditto Issue
I have the exact same issue as yourself and believe that the problem itself started after I rooted my device.
I am yet to take it back to a Telstra store however as there is no un-rooting method I can think of. (The Telstra ROM will not install on my rooted handset due to incompatabilities that arose from rooting the device.)
Your best bet is to get it replaced again because I've flashed every WWE and custom ROM known to man in order to fix this issue and have had no luck.
Some of the responses you'll receive here are just ridiculous (no offense, as that comment was not directed at any of the above parties).
Hope it all works out for you mate,
Cheers.
John.

Thanks John. I tried the same thing with the same result.
I ended up taking it in to HTC. Luckily I came across a good service rep. He said they'd seen some quality problems with the first batches of Desires and mine was not the first faulty proximity sensor they'd seen. My guess is the timing with the rooting was coincidental.
They would have replaced it, but they didn't have any replacement stock at the time...more evidence of early quality issues. They gave me priority and repaired it in 24 hours. It's been running fine under a number of ROMs since.
BTW I had problems de-rooting and reloading the stock ROM. Then I realised I just had to have the original goldcard in the phone and presto! One day I'll learn to RTFM properly.
Cheers mate and good luck with yours.

I have also this problem. When I make a phone call screen goes black immediately and there's nothing you can do. After the call is over I can wake up screen by pressing power button. I'm not sure when it started because there's been so many variables. I even destroyed my invisibleshield thinking it caused the problem.
Sensor list and sensor dump says that max value for proximity sensor is 1. Screenshots above there was at least 9. Also light sensor doesn't work at all.
I tried to unroot and go back stock but the problem still exist.
Have anybody found a way to control these sensors or do I have to send my phone to HTC to get it repaired?
Thanks in advance!

Hi, I have the same problem here with my proximity sensor since I have used a custom ROM (I don't remember wich one because I have tried so many Froyo ROM before the OTA).
I can't send my desire to HTC because my phone is out of waranty since I have installed all these ROMs.
Does anybody's got an idea, some help from devs ?

OK,
Maybe I'have found a solution to the proximity sensor's problem... At least my proximity sensor is working normaly now.
What I have done (you can found all in the xda posts) :
1. Going back to Hboot 0.80 => forum.xda-developers.com/showthread.php?t=741672
2. Rooting the desire and install the new recovery using unrevoked
3. Installing the OTA 2.2 without the Radio 5.09 (not a leedroid or djdroid or any other ROM, just a 2.2 rooted)
4. Configuring my phone
5. Installing the 5.09 Radio
I don't think that I have doing anything else, but now I can call someone even in the dark and my screen doesn't stay blank anymore !
Hope this could help someone.

[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.

hTC Desire camera LED problem

Hi guys.
Here`s my problem.
The camera LED on my hTC Desire won`t work in video camera recording mode(recording with LED ON), and also won`t work on the built in Flashlight.apk from Sense.
However, it does work on photo camera mode(if in dark places, it take photos using the LED - all ok).
I`ve tried different ROMs, with a full wipe(bot cache and Dalvik cache) in between the ROMs, and the LED acts the same in all of them(works only on photo camera mode - darkened places). However, I`ve installed the ICS ROM found here, on xda-developers, and this certain ROM has a small widget called "Torch", which uses the LED for a flashlight, and IT WORKS.
Now, if there was a hardware issue regarding the LED, it shouldn`t work on any ROM - basically it`s not a software issue.
I`m pretty much stunned here.
Has anyone encountered this before?
Thanks.

Hi,
I have a similar sounding problem. No camera, no camcorder, no flashlight, no led's. However the flash flashes when the phone is being booted. Thats it. I will try ICS to see if the flashlight etc works and let you know.
I have tried sense roms, AOSP roms to no avail.
regards

I`ve had the exact same problem in the past, regarding the LED, which didn`t work in any applications(flashlight, camera etc.), but strangely flashed by itself when the phone booted, and sometimes flashed randomly while simply browsing through phone(internet, games,) - without a certain pattern. I had to send the phone back for warranty, and they told me that there was a problem with a certain hardware circuit band which connects the LED and Power Button to the phone`s motherboard. I think you have the same problem.
U can try with ICS, but my guess is, it won`t help you.

Hi,
you were spot on. Got the beloved desire back from HTC (excellent service by the way). Thanks for your help.

[Q] Broken Phone - Strange Symptoms

After two years of use my Desire HD has developed some strange problems after I dropped it. The volume rocker does not work, the WiFi and bluetooth dont work and finally the strangest problem, that the keyboard does not come on when you want to input text for any App. The screen and touch input work without fault, scolling and selecting icons without problem. Making phone calls and internet connection seems to be OK as well.
I suspect I have damaged the motherboard or some other hardware, so before I buy a new phone I was wondering if anyone else had any of these problems and if so was it easily fixed.
Cheers

i knw this may sound strange but try flashing another ROM first,worth giving a try..

I did as you advised, which fixed the keyboard problem. The other faults are still evident so I guess I have damaged some hardware or cable. At least I can now use the phone to text message.
I will have to have someone take a look at the inside of the phone. Checked a diss amble video out and it looks complicated.

touchscreen problem

Hi guys,
I've rooted and flashed my htc one x cause it was starting to act strangely. the screen was getting non responsive, couldn't pick up the calls etc.. I thought flashing it would help but it wouldn't I tried Android Revolution HD 21.0 and no help, the screen started to act crazy /look at the youtube link/ even tried a different kernel, then I flashed Cyanogen and still no help. After the screen goes on the phone acts crazy /not everytime-but mostly when I need to answer or make a call ) I don't know what to do. any ideas?
thanks

Return to stock and send it in for warranty. Unlocking and rooting/flashing a phone is the absolute LAST resort to solve a problem.....

Hi,
the problems appears and goes.. it's not that it's acting like this all the time.. It just appears out of the blue and bugs me.. wonder what it is.. If I won't find out I might want to get HTC ONE from my operator..

and isn't it a kernel problem or something like that?
