Proximity sensor hell? - Thunderbolt Q&A, Help & Troubleshooting

I'm having a miserable time with my Thunderbolt all of a sudden. On every call the screen will go dark when i hold the phone to my head, but then inevitably it will light back up after around a minute. I've hung up on a ton of people and serenaded many more with dial tones.
How do i fix this?
after googling i've read a few generic android stories of people with long dark hair having issues like this. My hair does sometimes cover my ear. Do i just need to get a haircut?

Screen issues in call

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.

[Q] Proximity is dead and i can't end calls

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.

Proximity sensor & data connection solutions

Posting this in hopes that it will help someone else.
About 2 months ago I started to have problems with the proximity sensor on my N2. When I would answer an incoming call, the screen would go black, and I couldn't get it to come back on, without waiting about 2 minutes or doing a battery pull. After doing a little research, I found an easy method to recalibrate the proximity sensor. This worked well, but it had to be done every time the phone was rebooted. So I set up a gscript.
Recently did a little more research and found a recommendation to use compressed air and blow into speaker grill (where prox sensor is located), to disperse the lint that accumulates from carrying in pocket. This worked like a charm, and solved the problem, completely.
Edit: After several reboots, the data connection issue remains. Sorry if I unintentionally misled anyone. Proximity fix is still ok, though.

Display turned different colors first all yellow and other looked horrible now BLANK

The phone's been dropped a few times but nothing happened except a few very light scratches.Then I've left it in a bag and found it shattered.
A few months later I was like wtf? when I was watchng a video and all of screen turned yellow.At first I thought it was a film but no.Tried fixing by removing battery but the yellow tint stayed.A few days later it's been soaked in water.Booted once then froze.Had it repaired in phone service.The screen kept changing colours randomly.A few weeks later the screen went black and sometimes very rarely started working again until I turn it off.Now almost impossible to get it display anything.I've never harmed it and I'm having the consequences.I'm about to replace the lcd but I'm asking you if the screen is an issue or what?I've tried reconnecting lcd cable and it didn't help.I've been searching for the screen color issue lots of times and nothing relevant.What causes this?
Code:
TL;DR dropped a few times shattered in bag started changing colors water soaked fixed in service now blank.Im bout to replace lcd.
CAN it be anything else?I don't want to waste money.

*cough*
Dropped a number of times & 'soaked in water'. You sure you don't want to reconsider that comment ?
Sounds like the screen, but given the phone's 'history', you're only going to know if you replace the screen. If you're asking people on here to diagnose hardware issues with 100% certainty without having the phone in front of them, you're going to be disappointed (it's impossible). If you don't want to risk forking out money for a screen only to have other problems after you replace it, take it to someone who knows what they're doing to make doubly sure it's just the screen that's damaged/faulty.
P.S - Pro tip: Paragraphing/using some semblance of formatting will make it far more likely people will read your threads. Typing a couple of hundred words in one lump separated only by full stops & question marks will cause a lot of people to simply not bother reading your thread - it's just too hard.

My screen started being always off during calls regardless of rom

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
