I am posting this out of sheer desperation, I have spent the last 9 hours searching the internet for a solution to this problem and as of yet I have not found it.
Heres the problem:
My dad bought a HTC Mozart off ebay, as you know the mozart is a 'Windows 7' phone.
The phone works perfect, until you make a phone call, as soon as you ring a number or answer an incoming call the screen goes black until the other person hangs up or you remove the battery.
It's definately the proximity sensor, but no fixes have worked and I cannot find anywhere to test it in the settings but it does not respond to high intensity light being shined into it, headphones being attached, or hard pressing.
I have taken the phone apart and cleaned it out completely and the problem persists.
I have updated the phone to the latest OS available (7.8) but still nothing.
I have factory reset the phone, still nothing.
I am positive its the proximity sensor, and I want to disable it..
But now need to pay to become a developer? It all seems a bit too big a task for something relatively simple?
I am an iphone user, although my preference is to Android, I can root/jailbreak these with ease and have done to both a HTC Desire and a Iphone 4S, but this windows phone is giving me a headache!
Failing all software mods? If I just snapped off the sensor, would that bypass it? The phone works perfect other than that ridiculous little component (none of my other phones have this sensor?).
Thank you in advance!

Hi,
My HTC is giving me problems. The screen has become yellowish.
Earlier the screen used to become yellowish for 5-10 mins and it used to occur in two weeks or so. But now the phone has permanently become yellowish. I am also attaching a picture along with this thread. As you can see, the areas in the pic which are bluish is showing the true color of the background. Rest of the screen is all yellowish.
Can someone help me with this problem.
Best regards,

Looks like a faulty contact from your Motherboard to your screen (bad connector, bad flex-strip or something like that)
IMO you need to send it in for repairs.
I have had the same with my p3300, but was able to fix it myself (connector was not completely pressed down, had come loose)
Hardware problem?
Do you think this is a hardware problem?
Why I doubt that is because:-
1. Whenever I touch any place on the screen for opening an application, the area shows the actual color, but if I just touch the screen the colours doesn't change.
2. Usually the phone starts displaying the correct colours after a restart
Should I take chances and reset my phone or something?
I'm having the exact same problem every now & then (often occurs when I keep the phone in my jeanspocket) A light tap on the screen often helps. Had it in for repairs earlier, but they only re-flashed it (!) So the problem is not solved
What to do now?
I am not able to play any game. I hate looking at my phone. It makes me so angry.
How do I get it fixed. Its the fourth consecutive day with the wrong colours.
Someone please help.
Performed a hard reset but still not working properly
This is not happening. I performed a hard reset thinking that it might just work but it did not.
Can someone please help me here.
Of course it is a hardware fault. Send it in for repair - or repair it yourself
I think is a virus or something else, because has happened to many people lately.
I also had the issue as pictured above.....and exactly as described in the first post.
It began to occur about three weeks....and gradually was getting worse.
Its getting worse
Again I am doubtful that its a hardware problem.
Now, I am not even able to open anything on my phone. I keep getting thrown back to the main screen. No matter what I open, what application I am using, it just keeps throwing me back to the main menu.
In addition to that, even when I am not using the phone, it just keeps flashing. I lock it and the screen turns on again. Its like the phone is getting used every second.
I think its a virus. Does anyone know any anti virus solutions for HTC HD2?
Thanks,
Mohit Goyal
i got exactly the same problem - check my photos here http://forum.xda-developers.com/showthread.php?t=716002&page=2
i donth think it is a virus - why? - becase if it so the virus should go when you reflash the rom or flash a new rom - i douubt also about the virus but when install new rom the color issue still existig.
i sent my device to the dealer for repair and i will apdate you about the real reason when i got the answer from the dealer.
however, the same issue happened before to one of my friends and the device was out of warantee - he took it to a repair shop and they told him it is a kind of default in the mother board.
this time we will get dealer answer so lets wait.
thanks
a member in other forum advised me to use the attached cab which solve a similar issue in Blackstone.
but it is too late for me because i returned the device to the dealer
however- other member faced a similar issue and the dealer told him it a default in the motherboard.
Send in for repair......

Listen to the others... You need to send phone in for repair... My phone use to flicker on and off to the point where I couldn't call or use.... I sent to be repaired and they replaced the mother board, but didn't fix my other problems (phone will not turn off and when u put in battery phone turns on on it's own)..... I would send in for repair.......................
htc contacted me an inform me that the reason was the motherboard
yea its the motherboard isue i droped mind and d screen has changd its colour to yelow blue and sometimes wnt wake up aftr remvng 4m poket.gave it htc repair center they said a socket or conector has a problm whch cnt be repaired and so mothrboard needs to b changed.motherboard cost 8000rupees/190dolars whch is **** expensive for repairing
I had this same problem and read on some other forum that you're supposed to "flex" the phone. So I bended my phone a little (the top and bottom backwards, be careful the screen also has glass in it) to try to get a bit of a curve in it and by god ...it worked!!!!! The screen flickered and then the yellow screen was gone!!! I'm so glad because I mailed Htc two days earlier and I still don't have a response from them. I hope it works for you
Just to confirm... The same thing happen to me its either (A) the cable from MOBO to Screen came loose usually by flexing or bending the phone which can happen in someones pocket. (B) the cable connector came loose by same methods (C) MOBO went bad usually by same methods. Either way one should it in for repairs or crack it open and see for your self.
I got same problem before, it happened when the screen is moist. it looks like there is an absorbent layer behind the screen which got damped. try drying it.....found article to contained the unit in a seal container with rice overnite for drying electronic gadgets, and see the result.remember to take off the battery. good luck.
just bought my htc radar
the problem is when i start making voice call
the screen go black and i cannot do anything untill other person hangs up..
is there a way to solve this?
Do you have a screen protector fitted? Sometimes the screen protector can trip out the light sensor fooling the phone to believe your face is still pressed against it which will keep the backlight off etc, Had this issue in the past with my HD2 and HD7.

My wife has this same problem with hers. I found if you put slight pressure over the proximity sensor, that when you release it will function again. I'm guess that the glue holding the glass in place is faulty. This allows it to raise up slightly and cause the sensor to detect what isn't there.
I haven't tried tonwarrenty exchange hers yet with T-Mobile or HTC. Indo imagine that it's coming in the near future though. My wife is extremely annoyed by this.
I have the same issue. We have 75 HTC Radar company phones. A few of them have this very problem.
Most phones work fine after a hard reset, seems like some calibration error?

I am a phone repair tech and we have the same proximity sensor issue as stated above. We repair thousands of these phones and I would say atleast 25% of of these phones that come in the door have this issue and we have came to the conclusion that it is due to the sensor itself, for whatever reason, going bad, alot. HTC needs to address this problem, they need to either recall the phone or fix the issue free of charge. I plan writing HTC this afternoon and giving them a piece of my mind. If by chance anyone comes across a fix please let me know. We have tried everything that we can think of. I'll keep the thread updated as to what HTC has got to say.

Ya even i had a same problem.....! Plz let us know about what company says.....!
Did a quick search for this but most posts are on a similar but different issue.
During outgoing calls, the screen rarely, if ever, turns off due to the proximity sensor - I need to manually do it using the screen lock button.
However, with incoming calls, the screen turns off fine (due to the proximity sensor).
For both incoming and outgoing calls, it is often impossible to get the screen to light again once it is off.
Initially I thought my proximity sensor might be faulty, but the proximity sensor works perfectly in the diagnostics app. So it seems to be a software issue.
Is anybody else seeing this issue? Any solutions? I have the latest 1600.2487.8107.12070 update.
EDIT: Seems to be better after a hard reset, still not perfect though.
Same here
Sent from my Lumia 800 using XDA Windows Phone 7 App
I can't replicate your issue. Might be that you are somehow obstructing the proximity sensor with your hand.
Also don't have this issue. I find the proximity sensor to be actually oversensitive at times.
It toggles on as much as 5+cm away.
I've the same problem. I think the problem is due to the placement of the proximity sensor, not software fault. Proximity sensors should be placed as close as possible to the earpiece (i.e. the centre) of the phone, but stupid arse Nokia, with their billions of years in phone design experience, decided to place the sensor in the far-right of the top edge of the phone, so it doesn't register many times. Never ever buying a Nokia phone again, just out of the rage of wasting $500!
Disappointed by Nokia Care
I had a similar issue. Screen blacked out on incoming as well as outgoing calls and would not light up no matter what I do. It would be back to normal once the call was over.
Had to go to Nokia Care. They took my phone for 10 days and sorted the problem. However, they left marks on my sleek handset - chipped off the beautiful polycarbonate - as they probably opened the screen from top side. Also, the battery life has gone down from ~30 hrs to about 14-16 hrs.
Don't feel like going to Nokia care again as I dread what might happen this time around.

If I were you, I'd refuse the take back the handset and ask for a replacement. It's unacceptable that Nokia Care damage your handset.
Yea... I should have done that. But I didn't notice it then and was more busy checking whether the screen issues was solved. Don't think they will entertain a request for the same now... I will try though.
So I made the jump from Android (Nexus One) to the Radar and I really like it so far!
I do, however, have an issue with the phone that I am wondering if anyone else has noticed.
I have noticed that sometimes when I go to touch a tile(or other UI object)...if I quickly touch it, it seems that the screen doesn't always detect my touch. Sometimes I'll even hit it a couple of times before it responds.
The behavior is inconsistent though. After it smartens up and responds to my touch, then it seems to detect it fine. It's squirrelly and a little disconcerting.
I also think that the region of the screen might have something to do with it. The tile 2nd from the top on the home screen ("messaging" in my case) seems particularly susceptible to this problem.
Has anyone else noticed this? I'm a little paranoid because I bought this phone "new" from someone on CL and when I took it home I realized it was a refurbished model.
I had this problem when I had my 7 Pro. After a while it got worse, as I had to put the phone on standby and then turn it on again to be able to use the screen. I sent it in to HTC for repair, and they swapped the entire front panel with a new one.
Im having the same problem with my sprint arrive I think the problem is related to what is in this thread:

but I still cant seem to get it to work
Hey xda-community,
i've registered, because i have a strange problem with my LG G5 (H850) European Edition. If this is of any use, it's the Vodafone-Edition. Sorry for my language, i'm not a native speaker .
I got my G5 yesterday and was really pleased with the build quality (i was afraid, i was about the get some of those flawed devices as seen on the internet) and the raw power of the whole package. At first i didn't notice but then i realized, that the automatic brightness didn't work. Then i noticed, while having a conversation, that the display was'nt turned down. Up to this point it sounds like the known bug.
What i think (and please, push me into the right direction if i'm wrong - i'd love to take the shame not beeing able to look properly) makes the difference is, that after installing several sensor test apps from playstore, i always got the information, that both sensors are missing.
I took a trip into service menu and tried to calibrate (or better so say, to see if there was any sign of them) those sensors, but nothing happened. No reaction while covering the area where they are supposed to be, nothing.
Firmware is v10c-262-02. Tried to reset the phone and check while having nothing installed - same problem. I tried safe mode - same problem. I can check autobrightness but it doesn't have any effect whatsoever.
What really makes me shake my head is, that when i'm called and i turn the the display downwards to stop the sound, it works after 2 up to 3 times trying to cover the display.
I'd hate to send it in - maybe i'm just too stupid to look for answers, i'd really appreciate any efforts to help.
Thanks in advance and have a nice day.

Hey there,
short follow up to the problem. Yesterday evening i got a notification about an firmware update and wanted to install it. After hitting the proceed button nothing happened. Nothing. No installation, nada. I shook my head, deceided to return the damn brick and forgot about it. After an hour i noticed that my soft keys had changed their appearance. They got smaller. I asumed a kind of silent update (? nothing is shocking me anymore concerning this phone), checked the brightness control - no change. An hour ago i wanted to unlock my phone and got no reaction. I was about to hard reset it when it unlocked. I scrolled down the notification bar to check something when i noticed that the brightness was different from my setting. I hit the auto brightness button and bazinga. It changed by itself and since then everything works like a charme. The firmware version hasn't changed. I don't have the knowledge to explain anything or to know if something like this is even possibe (something was definitly new because all those vodafone apps where there again - which i deinstalled yesterday). Okay, long story short - either i'm officially going insane or they fixed it. Don't know, don't care.
Have a nice weekend!
Update: And it's gone again. I have no idea what to do anymore. I don't know if anyone is interessted in this, but i share the info anyway...
With Sensors (Umgebungslichtstärkesensor = Ambient light sensor, Näherungssensor = Proximity Sensor)

It certainly sounds like it *might* be defective, as you say that you have tried a factory reset.
It is a strange problem you have as it only appears to happen occasionally. It also sounds quite annoying. I know it is a pain to have t return it, but it might be better to do that and have a fully functional device, than to keep on facing this problem.
Sorry not to be able to give you a more satisfactory solution.
Good luck.

Hello,
thank your very much for your reply. I agree, i think it'll be the only option i have. I'll try to do return it, it's quite easy in Germany but, nevertheless, connected to some time without a phone.
Have a nice sunday,
Nero
I have this same issue with the proximity sensor and in my case it is because of the Lifeproof case is causing this, many others with this case report the same thing. Try taking out of the case and test again - mine works fine with no case; If this still happens, with no case on, then maybe the phone

Thank you for trying to help Sensor was damaged, send it in for repair and got it back. One can be sure that it's not a matter of blocked access to the sensors when a sensor test shows, that there are no sensors.
Told about this in so many forums that i forgot to tighten the loose ends. Sorry.
Kind regards
