(Video)Proximity Sensor Sensitivity Problem (TMOBUS HD2 vs HD2)

i think my proximity sensor is too sensitive because it ONLY works normal when i am outdoors at direct sunlight, but even when my shadow drops on the sensor it locks the screen, also in shade or in well lit indoors my proximity sensor doesnt work properly either.
i want to know if there is a way to change the SENSITIVITY of PROXIMITY SENSOR at will? i removed the screen protector so there is nothing on the way of the sensor.
also during a call pressing hardware buttons doesn't bring the device back from standby, hardware buttons are lit for a split second and nothing happens. is there any way to use the hardware buttons (except "end call" button of course ) during the call to turn the screen on?
t-mobile us hd2's proximity sensor works fine but mine has a problem, see the video here;
http://www.youtube.com/watch?v=OKCRqFYtLMs
thnx for your help..

Any idea?
Any idea? Does anyone have the same issue? Plz it's a very irritating problem I couldn't find a solution..

I havent own HD2, but eventually I will get it this year.. So, I wondering why you removed screen protector? because of sense Ui wont work with screen protector?

I removed the screen protector because I thought that it blocks the proximity sensor and cause it to malfunction, I searched the forum and some people had the same problem but solved it by removing the screen protector. But it didn't work in my case so I'm looking for a solution.
As you can see on the video the proximity sensor works normal under direct sunlight when i move it to the window, in the room it somehow doesn't work correctly..
(english is not my native language so pls excuse me)

Thank you
Thank you for your creativity with subtraction

Sorry for disturbing again but my problem is killing me i am desperate to find an answer could you pls at least share some ideas or recommend something to do?

İ emailed HTC for the issue and waiting for an answer, if you have any idea pls feel free to share i'm stuck with this annoying problem, thnx..

HTC's response
I do apologize there is no way to change the sensitivity of the proximity sensor on your device. You can try a soft reset by pressing the reset button on the back of the device. If that does not resolve the issue then you may want to do a hard reset on the device. Hard resetting the device will clear off the device and reset everything back to factory settings. You will want to back up your information from the device before doing the hard reset. If the hard reset does not resolve the issue then I suggest contact our support department..........

I guess I'ıı have to get the proximity sensor changed..
I searched eBay for a replacement but couldn't find it there are proximity sensor replacements for iPhones, I wonder if the iPhone's and HD2's sensors are the same?(probably not but I just want to be sure)

Hi a have the same problem. Did you found the solution?

well the promicity censor has nothin to go with light or shadows..it could be a glitch in the Radio or ROM try using a new radio or ROM

In call screen problem HELP!!!!

During a call
When a call is in progress, a shade covers the Phone dialer’s onscreen buttons to prevent accidental taps. Only the Keypad and End Call buttons are active.
Well for some strange reason this is no longer the case with my HD2, the shade is no longer there and all buttons are active without having to pull down which is annoying the hell out of me as I keep pressing random buttons with my cheek, anywhere in settings to turn this back on? I cant find it grrrrr!!!!

Have you installed BsBTweaks? If so, you've de-selected the Phone Slide Cover option.

Nope, no bsb tweeks, its really odd, and i cant find it on the settings page, oh well, was due another hard reset anyway!

Do you have screen protector? . If yes, take it out. And your problem is solved . Plz notify me . If you have a screen protector its not necessary, it will not correct your problem to make hard reset. If not..then we will what we can do for you

I have a different problem? When I make or receive a call as soon as I accept, the screen goes dark and I cannot see the display. I can tap any button and then it shows the display. Can I change that to c the display all the time? On my iPhone, it would go dark when I place the phone to my ear, but once I removed the phone from my ear, the display would be there. Thanks!

Man, do you have a screen protector yes or no ?. Because i had the same problem. Look mate, in the HTC there are two sensors. It is on the left as you watch the phone. Sometimes the screen protector becomes dirty, then this brings problem to the sensors. So, if you have screen protector please remove it, so i guess that it will work like the Iphone after. When you have the phone at your ear, the screen becomes black. When you remove it from your ear the screen appears. Did you understand me ?. If you dont have screen protector then we will see. Plz notify me.

Antonios76: Thank you very much for trying to help me and providing the information.
I do not have a screen protector on my HD2. I also keep my screen very clean, too.

[Q] End call screen freeze - solution?

I keep having this problem with almost every build I try in my TMO HD2. When holding the phone, as soon as I make a call, the screen goes black. When I end the call using the hardware button, the keypad lights come on and the screen is non responsive until I plug in the charger. Solution?

I too have this problem but not that bad.After ending the call the screen stays black for 3-4 seconds, but it is still irritating.

Well mine stays black until I insert the charger which renders any of the builds with the issue completley unusable.

this is already known problem, especialy with DesireHD build it gets worst. there is no solution yet, as I understood, but several workarounds, for example discussed in this thread
http://forum.xda-developers.com/showthread.php?t=835127

I always say it but maybe trying a different build would work?

Do you have BsB Tweaks installed? If so, this problem is caused by having the "Tap Time" tweak set to "on". I was having this issue and read about the fix somewhere (might have been here). I set "Tap Time" to "off" and.... immediate and permanent (so far, about a week) fix.

EndCall - black screen freez
same problem here... please help me !
i had installed on my hd2 DL.Desire.v4.31.44.12 and it's worked fine for a wile but now i tryed the last version of dl desire and a gingerbread build but the problem didn't disapear. I reinstalled radio that is version 2.15.50.14 but .. nothing seams to work
I need your help guys !
Sorry for my bad english.
I was curious to see if in wmo it is the same problem, but no... in wmo works fine.
it's strange that at first fresh install of dl.desire everything was ok, but now it isn't. I've reinstalled magldr but with the same results.
It doesen't work.
I think it is something with the proximity sensor, because when i turn on the speaker and the screen is on i can end the call with no problem and no freeze.
the only solution i have for now to unfreeze the screen is to plug in the charger cable in the device.

Problem Solved
I just cleaned the proximity sensor and it's working great. No freeze no black screen.

I have the same problem.

If you have the original screen protector with the 2 holes from htc, try to clean the sensors with a soft microfiber.
I didn't had this problem untill i replaced my screen protector with the htc screen protector. (the 2 little holes are exposed to dust and dirt, and when you remove the phone from your ear the sensor doesn't respond because of dirt. I think in android the voltage for sensors is a little bit lower than wmo, and that makes the sensor less responsive)
Sorry for my english.

install from android market ADW launcher....make it default home screen...try this one too..

Solution
Everything difficult-is easier)
Just clean dust on the sreen,where sensor is situated.

No Wake-up after phone call

Still tested different NAND-Android Roms on my HD2 but got still a problem. If i make a phone call and the screen turns black while calling i press the endkey to end the phone call. But instead of turning on the device, the screen stays black and i need to pull the battery and restart the phone.
If i make a phone call and use the free speaking funktion, while the screen don't turn off, i got no problem when ending the phone call.
I don't know what the problem could be, but it seems, that the thing has to do with the sensor who turns the screen on and off. But i don't know if this is the problem and/or know how to fix this problem. Like i said, i tested different Android Roms formated the SD-Card, deleted cache and all the stuff, but nothing fixed this problem. :-(

28 Views and no one with this problem? :-(

There are 2 other threads discussing this issue already. Here is one.
http://forum.xda-developers.com/showthread.php?t=946012
Issue lies with the light/proximity sensor. Could be defective hardware. Could be incorrect sensor drivers. Could be dirty sensors. I have yet to take mine apart to check for dirt on sensors. Blowing into the led/earpiece opening seemed to help. I notice if it doesn't come back on I can hold a very bright light (ex: cigarette lighter) about an inch away and the screen comes on as long as the lighter is lit. Sometimes it stays on.

thanks for your answer. seems to be more things to test and maybe solve this problem. Thanks!

THANK YOU Agoattamer!
Your link helped me to solve the problem! I just cutted a little piece of my screen protector, where the proximity sensor is, and got no more freezes after the phone calls! The screen protector still got two holes for the light and proximity sensor, but this seemed not to be big enough. Anyway, thank you a lot for your post!

I also tried a a lot of different NAND ROM and I had also this problem and I can't use Android efficiently. Now I am using hyperdroid ROM ( first GBX now CM). With this ROM and sanity app (from market, with correct settings you can find with trying) I almost solve this problem. ( probability of 95 % I don't get this error)

hey guys! i found the solution goin through the market!
download an app called "Sanity" theres a free version in the regular android market.
go to the settings > general > check "Reverse Proximity" (This will give you some warning about not using it if you DONT have a buggy proximity sensor). Check it anyways. Then go back to preferences then click "Proximity" scroll down and uncheck Turn off screen and leave leave the Turn on screen checked. this will force your phone to stay on during calls so that it never has to go through the proximity phase of calls this no more black screens. Hope this was helpful ^_^

what do u mean by front keys? as in the 4 soft keys?
i had the same problem with my phone (very dim notification LED and soft key lights). i sent it back for the manufacturers warranty, and apparently there's a part on the motherboard thats faulty. if you send yours back for a warranty claim you could get the problem fixed.

Yes I ment front softkeys. At the moment I have NO idea what to do with it.

I have/had the same problems as you do. I didn't find a solution for the keyboard and softkeys backlight problems, but I don't find them so annoying. I think it's just a little tweak and it'll be solved. About the non-responsive touchscreen while answering calls, I realized that it was my fault: I always put my MM2 on my pockets with the screen turned to my legs, as an old habit, since I've owned a lot of Nokias and their screens weren't that strong, and being a mechanical engineer I've always had sharp things on my pockets (screwdrivers, screws, washrings, you name it). What happens is that the screen is SO sensitive that it can sense the skin of your leg, and when it gets a imediate response when receiving a call, it would "crash" while it was still ringing. I could see who was calling, I was able to silence the ringtone through hardkeys, but the touchscreen was basically dead during the call. The solution that I found was to turn the screen side to outside, and I never had this problem again. It's a peopleware problem =P
Hope that helps you.

If you attach a rubber square to the back of your pocket (between pocket and leg skin) you may be able to solve this problem
BTW, gorilla glass is very strong against scratches, but it breaks easily. I'll keep my screen turned to my leg.
