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.
I have my lumia 800 for a week, and now its happening something strange.. When i'm in a call for some time, and i want to end it the phone doesn't let me. Its still responsive, i can go to the start screen, etc.. but the phone call remains on top with the message "ENDING". After a couple of minutes the phone freezs completely and reboot.
Someone had the same problem??
It's not happening always, but it's frustrating... I was having such a pleasant use and then this happens.. and i'm becoming a little sad and worried.
I dont's know if its a problem of hardware, it seems software because doesn't occur always.
Thoughts?

Yes, I also had some similar kind of problems today, i could not answer the call, after they called me about 5 times i could, but then could only speak a few words before the call stopped. Also i saw the call was still running after the caller had hung up. I wanted to retart the phone, but it would not start up again, then i took it loose from the charger , and it beeped and after a while it started up again by itself.After that it worked oke again.
I think they have to look seriously at the software, there is something wrong here i believe.
I've also had this problem of calls not ending on occasion. It seems inconsistent so far though. I'd be interested to hear if this seems to be affecting everyone or if it's only a small number of handsets.
I have the same prb. The screen goes blank and cant end calls. Has to force restart

For all WP7 devices the screen automatically goes blank when you are on a call and the proximity / light sensor detects your head up to the phone. However, if the screen stays off when you move your head away from the phone it means your proximity sensor (or software related to it) is faulty as it still thinks you have the phone to your head.
This happened to my HD7 after a nasty drop on a tiled floor the other day; the sensor was dislodged and permanently was set to the "on" position. I could only end a call by pulling out the battery, unless the other party hung up first. And every time my alarm went off in the morning the screen would remain dark and I would have to press the power button to get at the snooze button (this is because the sensor is telling WP7 that the phone is in a pocket or somesuch, and not to turn on the screen as the alarm could be accidently disabled or snoozed).
I fixed it by dismantling the HD7, resettling the sensors and blowing out as much dust as I could. Has been working fine since! I wouldn't recommend doing the same for your Lumia 800 though...
I dont think it is a proximity sensor issue. In doing tests, the sensor works perfectly for calls if I only have the screen off for a short period of time. If I hold the device up to my face for say 30 seconds, then the device usually freezes up and the screen goes blank, not allowing me to end a call. This makes me believe that it is a software issue that, hopefully, nokia can sort out.
Well i have been quiet on this topic as i wanted to see if the update fixed this problem BUT NO.
Today i made a call and it didnt ring but said connected i then pressed end and nothing it didnt respond infact none of the keys did anything my lumia just froze.
I couldnt even turn it off so i took the sim out and nothing still conected i just had a phone that was frozen with no way out .. so i had a usless lumia all day at work untill the battery died..I HAD NO PHONE ALL DAY !!!
I just hope it was not connected properly or my bill will be huge from t-mobile ..
This has happened a few times befor the update and always always when the signal is quite low it seems ..
But its a joke when im stuck with a usless phone all day ..
NOKIA SORT THIS OUT ITS NOT ACCEPTABLE
Hopefully this is a software issue and we haven't all received a bad batch of lumias with wonky proximity sensors.
Is there absolutely no way of reseting / rebooting the Lumia? you just have to wait for the battery to die??! That seems ludicrous!
i face the same problem many time i reset the phone by pressing power key long.
i find if i was in 3G network this problem some times happen ,so i switch off 3G and now it more than 3 days it never happen
Well to answer that question ...no its happened nine times last week, 3 of those 9 the phone is usless and you have to wait for the battery to die..maybe that's why Nokia gave us a short battery life haha, the other 6 times after about 7 min you can turn it off to reboot and the rest of the phone is responsive .. So 30% of the time when it happens U have no phone :[ even a long press of the power button does nothing
Same problem here... You can restart the phone btw: Hold power button for 10 sec, then release the power button and press it again...
This is a big problem for me, hope a fix comes in fast...
Thanks,
Samo
Im having the same issues here. Other than this its a great phone. Hopefully get it sorted soon.
same problem here, although never had to wait for battery to die.
long hold of power (10sec+) usually reboots the phone.
I keep noticing the problem when changing locations (inside/outside buildings) which is usually connected to switching to 3g - if it happens during a call I am unable to end it with screen being responsive and phone saying that it is ending call (for 30 seconds and more)
contacted Nokia regarding this problem.. they told me to reset my handset.. this is the only option they have... DUMB
same problem here... did someone find any solution?
nopes........

You can hold the power button for 10 seconds, this will trigger a reboot.
I'm relatively often facing the same issues, worth noting is that it does seem to connect the call as I have had customers tell me they heard me grumbling before the call got disconnected (so I gotta be more careful with grumbling )
Happened to me last night, just turned the phone off (power for a few secs then slide down) and on again.
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

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.
Hey,
Got my new Lumia 800 (RM-801) Black yesterday (Orange PL Branded). Wonderful phone.
But there is a huge issue:
When i recive or make a call this will happen:
1. Screen will freeze - Black screen, cant hang up, cant turn off nothing
2. Screen freeze the caller can hear me but i cant hear anything.
So i cant hang up, the phone is frozen until other side hangs up.
I have the latest software update: 12070 but nothing happened the problem is still there:v
i tried numerous times of factory reset, backup recovery, setting everything. I dont even have any screen protector to block the Light senzor (The senzor must works because auto brigtness regulation works great). I cant even debrand phone because the Nokia Support Tool shows im up to date and dont give me any option to flash any firmware.
Tell me what can i do ? When i get my lumie to Service i will be withour phone for month and thats SUCK big time.
Hope there is some solution.
I finally got my phone Unbranded , but problem is not solved.
Same problem. Got Developer Gift Lumia 800.
Same issues until i took the plastic film from the front of my lumia
Now i do not have a single issue....
Haha hope this helps
Don't have any film on the screen
I've also experienced my phone freezing while making a call.
Hasn't happened often (3 times), but that isn't a good indication of the seriousness of the problem, as I don't use out often to call (have the luxury of using the Lumia as my 2nd phone).
I believe that in my case it occurs after my phone is on for an extended period (hardly using it, with flight mode activated) and then making a call.
I've reported my problem here:

My heart sensor and the pedometer and the light sensor stop working all together after sometime. Even the auto screen brightness stops working. But all apps and phone calls work. I am using Sprint and my gear is paired with my Note II. Can anyone help on this I hate having to reboot the watch ever time I want to take my heart rate. And auto screen brightness stops working.
From the dial screen, type *#0*#, you will get to the hardware diagnostic screen for the gear S, select sensors, run the test for those sensors you have an issue with. You may also try *#7353# to execute some self test.
All the sensors are unresponsive with the test codes you give me. If I reboot the watch and do the codes again it works fine. Seems to freeze after I receive a notification. Seems to be a software problem. I just wanted to know if anyone else is having this problem.
At least yours works with a reboot. I have been using mine since I bought it from best buy in early March. Yesterday I noticed during a trail run that my screen would not wake and my steps were not being counted. I rebooted several times and did a full reset of the device. Luckily Best Buy honored the 1 year warranty and let me exchange. I'm really concerned about this happening because I just got it a couple months ago and had hardware problems without ever mishandling my watch. I sure hope I don't have to constantly exchange it every few months.
I have the same problem since the last software update. I have bought my Gs directly from a Samsung store. You resolved your issue?
I haven't run across this issue since exchanging it. However I had two additional exchanges since then due to screen flickering and another time my screen started going black.
