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.
Hi I have just got a HTC radar as a company phone and am getting some odd behavior when dialling
Sometimes it works like expected other times when I press call the screen goes off and will not come back on no matter what I do until the other end pick the call up
Now that's not so bad until you call voicemail when nothing makes screen come on ie tried moving away from anything (in case proximity sensor turning it off ) tried the on/off button volume even camera button nothing works so I can't press option 1/2 etc
Only way I can end the call is to remove bottom cap and take sim card out
This happens on around 50% of all calls and is really bugging me , if its connected to a bluetooth car kit ,the car kit can end it ok
Everytime on bt kit the screen goes off with pressing call
Anyone else having this problem?

Nope, mine works perfect. Sad to hear tho...
Had that problem with my dell venue pro. Its a fix for it that I found under the dell venue pro forums of xda. Not sure if u can get the same access for the htc

Do you have a screen protector? If so it could be one of poor quality and is interfering with your screen. Remove it if you got it. Also it can mess up your ambient light sensor/proximity sensor.

Nope I have nothing on the screen its as it came
Have reset device still the same I'm guessing it has a problem , sad to say but HTC aren't impressing me lately even thinking of replacing my sensation with a galaxy nexus soon :-(

I'm having the same issue too. But i do have it all the time, with every single call i make.
Lets test something here:
Grab a flashlight and turn it on
Cover the light sensor in the upper left with your finger and make sure the 3 capacitive buttons light up.
Uncover them
Now shine the flash light directly into the light sensor
Did the lights turn off? If not get your phone replaced. If they did then you or something is covering the light sensor. The light sensor can turn the screen off at around 1".
I wrote to HTC, they replied after 1-2 hours:
"this is a functional problem caused by a sensor inside the phone" ... "if you can please do get a replacement phone if you have just bought the phone"

I asked my local dealer, i will receive a new device tomorrow.

Tried this but nothing happens while call is active , I rang someone today got their voicemail I left a message but after my message I couldn't end the call I had to connect it to my car kit and use that to end the call
Time for a new handset here as well I think :-(

What was the outcome. Did the lights turn off?

For me, the light turned off. In fact I do not need to shine a torchlight. If I cover the top part of the display the 3 capacitive buttons light up. If I uncover, the light disappear. Any ideas? The screen is turning off every time I make a call.
That tests the ambient light sensor(s) - most phones have 2 or 3 - but it doesn't test the proximity sensor... (because the button lights should be tied to the ambient).
Either way, I have not heard of this issue, though HTC has pushed out a firmware update over zune for the Titan recently. I'd recommend to check that, and if there is no update/doesn't fix, then replace the phone.

The light sensor IS the proximity sensor

Is my sensor working properly then? I have a screen protector installed. Is that the problem? I have not tried taking off the protector yet.
You should try that. Some cheap screen protectors can mess with it. I know this was the case with some protectors on the dell venue pro early on.

o.0!? The proximity sensor is normally a led rangefinder in the infrared frequencies. Light sensor could cause lots of false positives...

Fixed the problem. You must remove the clear stock screen protector...it distorts the sensor.
I've been saying that all along
I did a test. Peeled off a bit of the screen protector, enough to expose the sensor. Made a call. The screen didn't blank. So it's the screen protector.
Hi guys I have just recently bought a Radar from bay and im having the same problem, but this time there is no screen protector.
If I cant get a refund form the seller, can I get a warranty repair seeing as though im a second owner?
Cheers
Hi,
I first thought that the Nook Tablet doesn't have vibration feedback at all. But at least there ( http://iamafanof.wordpress.com/2012/11/18/cm10-0-jellybean-sdcard-img-for-nook-tablet/ ) in the comments somebody talked about vibration feedback in skype.
So I am not so sure anymore! I found no previous thread about this topic, so I opened this one....
Anyone can confirm that the Nook Tablet has or hasn't vibration feedback? If it normally should have it, it might be a problem on my side? I would be more than happy to have slight vibration feedback when using the keyboard!
I bought this used, so it also might be defective, or maybe has a third party battery internal and the vibration is inside the battery? Or is it a problem of CM (10.1) ?
Thanks already!
--------------------------
Ok, after searching for a while, I have found the following, that probably settles it: No hardware for vibration feedback in Nook Tablet:
http://www.androidfornook.com/forum/thread-1071.html
I think it could be possible to do hardware modding to add vibration, but this would need some work:
- Find Documentation which way is mostly used in android to connect a vibration motor to a omap2430
Depending on how easy this is (maybe just some transistor + vibration motor connected to the right pin of the chip), it might be possible to do
It also depends how easily those pins are accessible in the Nook Tablet hardware design ...., this needs to be checked
- design a small suitable circuit and use the vibration motor from an old phone / vibrating toothbrush, ....

AFAIK, it does not have vibration feedback. That feature usually exists for phones. There's a tiny little motor inside that makes it vibrate. The Nook Color and Tablet does not have any vibrating motors inside.
If you want noise feedback for incoming Skype calls or notifications, you can change that in the settings menu.
New Z2 user here. I was wondering if the performance of the vibration motor on my Z2 is normal. It seems to need to spool up before it functions properly...ie the single short vibration while typing makes a weak vibration and a weird hard to describe click or rattle noise. Vibration during ring or notification is fine and rapid key presses produces a normal vibration.
I found some threads with users that have had the same experience. If the Z2 community could help out by testing the vibration function through the service menu, I think we can come to a definitive conclusion: either Sony made the Z2 with weak motor or there are faulty motors that made it out to production.
From your dial pad enter *#*#7378423#*#*
This should bring up the Service Menu>>Service Test>>Vibrator>>set speed to 50 ms. Please post your results.
50 ms produces click or rattle and weak vibration
3000 ms produces normal strong vibration
Thanks for any input.
Also first post.
50ms feels just like pressing the nav keys
i had a defective version before this one and half the time the nav keys didnt buzz, it was like the motor voltage was too low or it was stiff
Another thread about this stupid sensor.
My screen goes black when I call or answer a call. If I use a headset sometimes randomly the screen comes on or stays on when I answer a call.
The proximity sensor is working. Looking in *#*#7378423#*#* > Service tests > Ambient Light Sensor.
Putting it to a lamp gives a value of 10.0 and putting my finger over the sensor gives 0.0 .
So its working.
This seems to not be rom related if not for the change after Android 4.4. I flashed roms from cm-12.1-20161016-NIGHTLY-togari.zip, AOSP_N_161207_togari.zip and now I am on hybrid_concept_edition_2.0.zip.
I do have a screen protector on. But with a hole for the sensor. Its not dirty in that area. And the sensor worked fine way before I installed it.
This started happening during the last two months or so.
I tried numerus of apps from play store. None did anything. Of course I could force the screen to be on. But with the risk of pushing some buttons when I'm in a call.
My temporary fix so far has been to enable end call with power button
Do you have any idea what to do?
Thank you
I'm facing this same problem, I'm on stock.

yup.. I had mine apart today. But you need to remove the battery in order to flip the motherboard around to get to the connector.
I don't have time for that. Perhaps the battery will explode if I try to remove it..
So I cut a piece of foam plastic to fit around the usb connector so there is a constant pressure applied to the motherboard when screwed down the NFC antenna because there is a screw just around this area that sets the NFC antenna in place.
Hang on. I just made a call just for the sake of it that you answered to my thread and it freakin works!!!!!!!!!!!
I got the idea from this guy/gal: https://forum.xda-developers.com/xp...olution-proximity-sensor-fix-z-ultra-t3595525
