I have very annoying issue with my HTC HD2. During call my screen goes black and when I move it away from my face it doesn't turn on.
But when I put the device in horizontal position with screen facing down it lights. On the other hand when I put it facing up it turns off again.
I guess It's problem not with proximity sensor but with g-sensor. I have this problem both on stock WM rom and Android. I used Task29 and installed stock rom again and for the first time it helped. Now it doesn't change anything.
I downloaded program called proximity recalibrator. And again when I'm shaking the device it changes near/far position and real distance from objects doesn't matter.
I made short movie to show you the problem:

Do you have any solution?
Hope this helps..........I had the same problem and tried various reg tweaks and BSB tweaks etc but nothing cured it, I finally read a post on XDA stating that it was probably the screen protector confusing the light sensor, I removed it and hey presto, Sometimes its the simplest things that are the best lol.
I don't have screen protector so it has to be something else

Hi,
have u ever solved this problem?
I started with this probel after a hard reset (stock rom 1.66 ita): with the same rom before hard reset it was working correctly, now it behaves randomly...
I have this problem occasionally with my HD2. I keep it in an Otterbox Defender case, and dust and grime build up on the screen in front of the sensor. When I take the phone out of the case (which has a built in screen protector) and clean both the screen protector and the phone's screen, the problem goes away.

Ok... I apolagize in advance if this has been muted before, but I really dont know what to search for.
My problem is, that when i make a call the screen turns off, ( As it should ) but when Im asked to tap in an extention number or 'press 1' etc I cant turn the screen back on, all the soft keys light up but the screen refuses to come back on untill I end the call.
If I dial in the number and the screen goes blank on connection, some times im able to turn on the screen if I move quickly enough and press the sta key.
Im running a htc hd2 with an the latest energy rom.
ditto
have the same problem, would love to find a solution...
Same problem here so I D/Ld Phonex from Iconsoft. Really like this a lot better and is so much more user friendly.
I'm not sure if you're having the same problem I was, but it sounds very similar...
What I discovered is that at the upper left of my screen protector, there are two round cutouts for the proximity sensor. The screen protector has never adhered very well at this point, and it was pulled away from the glass, causing the phone to belive that it was constantly near a face, and blacking out the screen.
I discovered this after being so frustrated that I removed the screen protector, and *voila!* the telephone worked as advertised. I used a hair dryer to warm the screen protector to re-adhere it, and the phone still works properly, but I don't know for how long.
I understand that there is a registry setting to disable the proximity function for the phone, but I haven't gone to this length.
I hope this helped!
I had the same problem till i change te Radio version to 2.10 or above then it disappeared
I have the same problem, screen protector causes this problem for me....
Hi guys,
Ill start with saying that my english is veryy bad
But my problem is:
I quess my light sensor on my hd2 is almost defect.
why?
When i start a call (or got an incoming call) the screen turns black
(as its suppose to be when you hold it to your ear)
But it turns black all the time, no matter how i hold it.
So i did a quick test, i called a number, and took a very bright light (100w) just next to the sensor. and after that, it doenst turn black for the first time!
So the sensor isnt working correctly anymore?
It is since my telephone has gone back to the shop for a new screen.
Can i make it better with software? Cause it works.. But only with a very bright light.... Or do i need to get back to the shop?
thnx
try a soft reboot and then if needed a hard reboot/factory reset. don't forget to back up the phone first as it wipes the phone
Sorry, i was forgotten to say:
Ive tried different roms, and even Android. Results are always the same!
That is an odd problem. Especially since the ambient light sensor is not what is used to black out the screen during calls. That would be the proximity sensor.
If you look very carefully just to the left of the speaker at the top of the phone you will see the proximity sensor. Do you have a case on your phone that may be blocking/interfering with this sensor? Do you hold your phone in a way that your fingers or hand may be close to this sensor?
Another thing to try is put the call on speaker phone, this should disable the proximity sensor and keep the screen on. If it does not then you may potentially have a hardware issue.
I haven't got something blocking the sensor. But because my screen was broken, they placed another one. (And since then it happend)
Ok, i did some tests..
I cleaned the screen very proper. And i was sure there was no spat of dust or whatever. so i called again.. And it worked properly!
But.. When i put my finger on the sensor.. (So its not 100% clean anymore) it turns black again. So its veeeeery sensitive..
When i turn on the speaker.. It doesnt turn black..
So conclusion:
It turns back way to fast. Only when the screen is 100% clean, and there is enough light in the room.. It works properly..
Aren't there any settings for windows or android to change the sensitivity? Cause this is very annoying..

Not that I'm aware of. It sounds like they didn't do a proper job of replacing the screen. The ammount of light in the room should have no impact on the screen turning on/off. Also, my screen is often quite filthy and I've never had that trip the proximity sensor. It is possible that the sensor was moved or misaligned during the repair.
Hi everyone,
funny thing happened to my Mozart. Whenever I make a call the screen shuts off like it should, but it doesn't turn on again when i remove it from my ear until the call has ended.
Which works fine if the other person hangs up, but it means I can't hang up. Whenever I reach a voicemail i have to take out the battery to hang up!
First i thought it was a rom issue, i had just gotten my hands on the mango beta when i first noticed it. I thought it might be buggy.
But the problem remains after hard reset and flashing with a different rom (pre-nodo & nodo).
I found out that the sensor still works. The screen is reactivated when i shine a bright light (halogen spot or so) onto it - but only for as long as the source shines onto the sensor, else the screen shuts off again. wierdly enough, direct sunlight doesnt seem to be enough to trigger it anymore.
since i upgraded my phone with a 32GB microSD I guess I'm not eligible for warranty, huh? but im pretty sure it happen long after and i didn't accidently break something while opening the phone.
very weird... any ideas?
I had this problem on the weekend.
I removed the matt screenGUARD, and the problem disapeared.
Also you can reactivate the screen by pressing the on/off button...
thanks for your comments.
unfortunately, I don't use a screen protector and the standby-button doesn't work during a call
I have this problem also, with stock 7392 rom. The sensor seems to work when dialing, but stops a short time after a call is connected.
The power button works for me to turn the screen back on however...
Where is the proximity sensor ?
where on the device is the proximity sensor located?
I have been having difficulty with the screen not switching on during phonecalls and I have to remove battery to end outgoing calls. Pressing the power button doesn't help either. I don't have a screenguard to remove.
The problem started not long after, but not immediately after my daughter dropped the phone down the toilet. It took a few days for the phone to gently dry out and it worked again except for some residual water between the screen and the glass.

The sensor is about 1 cm to the top and right of the htc logo. It's barely visible and it is dark violet. (Or something like that, I am not very good at naming colours.)
Anyway, I sometimes also experience problems with sensitivity with HTC Mozart, mostly during calls, especially when the proximity sensor has been activated. Sometimes the home button freezes after a call... It's a bit annoying.
Sorry I have searched and searched to no end. Here is my problem. I have the latest ICZen running on a Samsung vibrant. My proximity sensor is dead (tried swapping cleaning and so on) I really want to keep this rom but I can not end calls or input numbers during a call when the screen blanks out. I have tried several apps and fixes with no luck. Is there anyway I can get the phone from the ICS passion version 13 and put on this so I can shake the phone and press the power button to get the phone to wake during a call? or is there another something I can get to fix this issue? Any help would be much appreciated.
Never mind, i scratched the gray semitransparent paint off the back side of the glass where this sensor sets and got it working. I tried it first without it in the glass and it worked so even though it was perfectly clean it was that paint.
I have a very irritating problem my device touch screen is responding even though it is black and locked. It keeps annoying me when i am in a call and it is only a matter of time till it ends the call. Problem started after having a screen replacement but i can hardly believe it is a screen problem because it is functioning normally and also gets dark when i am in a call. My proximity sensor is working as it should. It is like my screen gets dark and not totally off.
My phone is rooted and i am running lollipop 5.1.1 custom rom

It sounds like you are having ghost touch problem. This usually presents itself when you change the front glass with digitizer and leave the old LCD. This cannot be repaired if this is the case. I dont think this is a sw problem. When did this issue started to manifest itself? Right after the screen replacement or it started to appeare gradually?
Yes it appeared just after repairing the cracked screen. The lcd was working but not the touch and the glass was all cracked.
How can i solve this?

One thing to mention is that i do not get touches that i didn't make. They are just getting read when the screen shouldn't read them.

But does touch work normally when you use the phone? Ghost touch can manifest itself on various ways, like your case or can go completely crazy when the screen is on. You can try some apps that resolve ghost touch like touch fixer. Some people are saying that unlocking BL and flashing CM resolves this issue and other sollutions you can try is to apply heat with heat gun or hair drier directly on the screen to make sure the glue is sticking the digitizer onto the LCD propperly, or fiddle with the flat cable contacts bit by bit until the touch is working properly but this requires disassembling the device again. You can alway try to flash different firmware to see if it'll resolve your issue but I highly doubt it will. GL
