Got my screen replaced this afternoon.
When I recieved my fixed phone, my fingerprint sensor wasn't programmed.
I went to the Security Settings and went to turn it back on, but it wasn't showing an option for a Fingerprint to unlock it.
I went to the Smart Cleaning Extension, optimized my phone and then went to test the hardware and every harswarw passed except the Fingerprint Sensor.
Quick Help didn't help at all.
I dont know what to do.

Have you resolved your fingerprint problem?
I have a slightly different fingerprint issue. The V30 T-Mobile phone I purchased had a cracked back cover. So I replaced it with a new one following in detail the repair videos on google. After I put it together, the fingerprint option disappeared. Has anyone experienced this? Any resolution?
Thank you.
My LG V30+ fingerprint sensor quit working after I replaced the wide angle camera. It disappeared from the software menu and failed the hardware test. I replaced the fingerprint sensor with a new one without success. After examining the fingerprint sensor connectors on the motherboard with a 10x eye loupe (from Harb. Frieg.), I discovered that I had damaged one of the connectors when I removed the mid-board and main-board. The little gold connectors are spring loaded and circled with super thin aluminum looking strips. They are extremely fragile. One of the strips was bent down, and when I tried to bend it back, it broke off and fell on the table. It was so small I could barely feel it between my fingers. I suspect the fingerprint sensor is failing the hardware test because the connectors on the mainboard are damaged. I also suspect that the reason the software options are missing is that the system fails to detect a fingerprint sensor during the boot process and therefore does not load the fingerprint software options.

I'm curious to know if you were able to fix this issue after discovering the problem or if it is a lost cause. I'm having the same problem (no fingerprint option) after having someone else replace my screen and back glass. I'm not sure what else caused it or what to do about it.
I also got the same issue. My phone came back from the shop with heavily bent pins. Though I was able to bend most of them back (they're actually quite flexible, won't break easily as long as you're careful), one just won't return to its original state. It sits slightly lower than other pins and takes less force to compress.
Anyway it still works if I press on the connector. So if you're facing the same issue, try pressing the area to the lower right of the sensor whenever you need to use the sensor. If the phone detects sensor failure it won't work until next unlock.

Had this phone about 3 weeks now and all of a sudden whenever I make a phone call the screen just goes black until I take the battery out or the other person hangs up. Is there a way to tweak the proximity sensor settings like on the omnia 7 etc?
I'm having the exact same issue. I've only had my Titan for about four days now.
I just firmly pressed on the front and back of the device as if to correctly place put the back case on. This works for a while and 'randomly' quits. I have yet to figure this one out.
I've not had this problem but you could try the other rom from here. I had the .02 but changed it to .06

Thanks! I'm gonna' try flashing this. HOPEFULLY, it will work.
I'll post back with my result.
Nothing! Tried the ROM update but no luck. Still having the same problem.
Dam thats a shame, could be a hardware issue
same issue on mine. Had it 2 weeks and it just started going black when calls come in or go out. I have a replacement on the way, I hope its an isolated issue...
Same here. Had mine for 2 months and now I have this issue.
Any ideas on how to solve this yet?
same here...
any hints if its a hardware issue or a software issue
mine also worked a wile and then stopped working...
You may already have tried or been aware of this so forgive my two penneth worth, When I had my HD2 It was the screen protector that tripped out the light sensor and kept the screen dark etc, May be worth a try if you have one fitted as it did the trick.
HTC Titan Prox Sensor
I do hardware repairs on phones, and currently having this issue with an HTC Titan. It seems very likely to be a hardware issue. The back cover feels loose and sloppy in my opinion, yet seems to play a role in properly grounding some of the auxiliary sensors. I'm considering trying to order the part, but it seems to be impossible to find except from a used phone. The proximity sensor is on a small chipboard that snaps directly into a connector on the motherboard. The solution of pressing the screen and back housing together makes sense if that proximity sensor isn't making a good connection to the board (or if it isn't grounding properly).
In my experience, I'd say this phone is a pain in the butt to diagnose and repair.
Exact same problem! Was thinking about doing a hard reset, but it seems like that won't fix it. I bought my Titan used, and maybe that's why it was on eBay. Phone works perfectly otherwise, absolutely love it. They sell new covers on Amazon, maybe that will fix it, by applying more pressure on the proximity sensor. Wish there was a simple fix.
I have this issue as well. I have found out that when you press the upper right corner of the screen the display comes back on but as soon as you let go it goes black again.
Also if you slightly open the back cover from the bottom the display comes back on as well but you lose signal because the antenna is disconnected. When you close the back cover the display goes black again.
It happens with outgoing and incoming calls.
This is really annoying and if I would very much like to know if it's a hardware or software issue.
---------- Post added at 05:38 PM ---------- Previous post was at 05:20 PM ----------
Update:
I think I've found a solution.
I believe the the proximity sensor is in the narrow gap above the screen.
I opened the back cover and I slightly scratched the two contacts on the top of the back cover with my fingernail.
My Titan somehow is now working again and when I move my finger close to the narrow gap the display goes black.
I therefore think it's just a matter of a dodgy contact between the proximity sensor and the back cover.
I think I'll order a new back cover fom eBay to see if this improves things. My back cover is damaged anyway.
Possible Solution
i hope this is the solution cuz im tired of messing with this phone (we lost money trying to repair this phone, ie. negative profit, cuz the lcd and digitizer are fused together and it took forever for the parts to be available online). BIG Thanks to everyone who contributed to this forum thread.
The problem is almost certainly hardware and related to the back cover. good news means that it should cost nothing to fix. *warning* as always, you could break your phone if you arent careful. I havent tested this solution but i will tomorrow. On the motherboard are "metal brushes". That means springy metal contacts that are meant to make contacts between parts that arent closely touching. look at the back cover and find those contact plates, then look on the board for the corresponding brushes. gently pull those brushes up away from the motherboard to make them extend further, and see if you can get the back cover to fit more snugly on the phone. be careful with those brushes, metal can only be bent so far before breaking and then youll have to do board-level soldering (pain in the butt, not easy). if you can ensure proper contact between the back cover and the motherboard, then you shouldnt have any more issues with the proximity sensor.
this is my educated guess, let me know if you have any luck.
PS! been using iphone 4 for like a month, and the more i use it the more i hate it. i typed this up with iphone 4. so much hardware power with so little control. id recommend iphone to anyone who doesnt like technology. iOS is a POS
Called HTC and I'm still under warranty. I'm going to be sending in the phone for repairs tomorrow for this problem, we'll see what happens. They said it'd take 14 days to get my phone back.

Hi Flavio, have you bought a new cover? Has it fixed your problem?
Have the same problem with the sensor, i´ve tried other roms to, but still the same problem. i dont think, that this problem is a hardware issue of the proximity sensor, becaue sometimes it works sometimes note... very curious...
I just got a new Titan with the same problem. I took the phone to HTC repair center and the repair status on their website shows is that its been fixed, meaning I should get it back early next week. I will report here about the description what they did to it.
And this is clearly a HW issue. Taking off the back cover seems to affect little, but not 100% remove the problem.
Had this issue. When I sent it off to HTC they replaced the screen together with the dusty FFC issue
I had a similar problem that was fixed by turning of "Automatically adjust" in the brightness setting.
hi.
Today, I've dropped my phone. At first glance it was fine, but then I realized the speaker wasn't working.
I opened the phone, cleaned the speaker's connector with alcohol, assembled it back and it works.
But then I found out my proximity sensor is also damaged.
It became so limited, that during a call, the screen may turn on and off repeatedly, or won't turn off at all, or won't turn on after moving the phone off my face.
So, I would like your help in two things:
1.Is there an app for ICS that can help me test the proximity sensor? I remember GB has "SGS toolbox" that could test everything including the sensor.
I just want to make sure the problem is really the sensor and not something in the dialer app.
2.Assuming there is problem with the sensor, I would like to look at it, but I don't know how this sensor looks like and where to find it inside the phone.
I hope for your help, and thank you very much.
Ok I found a solution so here it is for anyone who may find this thread:
The proximity sensor is on the same assembly as the earpiece and the headphones jack.
Turns out, the flex cable of the assembly is cracked. To make is worse, the crack expended once I took the assembly out so now the earpiece doesn't work too.
I have ordered this part from eBay, it costs 5$.
But it will take a few weeks to arrive since it's shipped from China. That's some bad luck.
After I updated my Nokia Lumia 920. the screen turns off when im dialing someone, and the only way to get it back is to restart it or if the person on the other end hangs up.
Could it be the light sensor? or is it just the phone update that messed it up?
http://discussions.nokia.com/t5/Nok...n-t-switch-off-Lumia-920/td-p/1606440/page/10
Thanks!
I will return it tomorrow, since im not ready to open it after 20 days of use
now its REALLY FIXED but need to open the phone (only two screws )
Symptoms:
Experience screen and touch sensor switch off during a call, Notifications (the screen stays off, like if it was in a pocket) which doesn't turn on as usual.
Try:
If during a call you press and hold the upper left corner of the glass -just between the speaker and the upper left corner- you will notice that the sensor works as expected.
I think :
Because of the layered nature of the phone internals design and the heavy use of ribbon connectors it had to be tight to connect the board with the sensor.
My Solution:
I just added a peace of sponge (W:4mm/H:5mm/L:15mm) (all weather door and window sealant) -that comes self adheasive from one side- and sticked a small peace on the board on the opposite side of the phonejack/secondary mic connectors (Pictures attached) this will add pressure on the board to be more tight tried it and working as normal.

Mine is suffering the same issue. In the Nokia forums one user recommended to "blow air" across the top of the phone where the display meets the case right above the Nokia logo. I did this and now my proximity sensor is working. It's got to be dust getting on the sensor. I'm going to take mine apart and see if I can come up with a seal for the FFC and proximity sensor.
I've been having some issues with my proximity sensor.
So, I installed stock ROM from Samsung...enter the TEST MENU...and hit the SENSOR.
For what I've read, if I covered the sensor, the screen should go green and the device should vibrate.
However, my screen is already green as soon as I press the SENSOR test key and vibrates without stopping at all right from the start.
The results shown is....UNcovered: 17 covered: 251
Is this a faulty sensor? Can I calibrate it?
Is there any solution?
PS: Is there any cooked rom with the ability to turn down the ability to turn off the screen when making a call, such as it is on stock rom's?
Are you using a screen protector or a protective case that can possibly affect the sensor? If yes, try removing whatever you can remove. See if the problem persists.
I remember buying a certain protective case from Otterbox, I think it was commuter, that can trigger or affect the proximity sensor because the cut of the silicon case was not big enough. Good thing I was able to return and replace it with something else.
Dust or dirt can also affect the sensor so try checking that.
Hi there.
First of all, thanks for your answer.
I don't use screen protector or any kind case.
My S2 is quite good, without marks or scratches of any kind.
Can't tell if there is any dust inside....
Any thoughts?

You can try the following:
- Proximity Sensor Calibration
- Using a vacuum, try to vacuum the upper part of S2.
- Use an adhesive tape once or twice to clean the sensor and front camera area.
- Remove the battery for 2-5 mins.
- If you have Viber, uninstall it then check (though I think they got this fixed since late of 2012).
- Try another battery.
- Flash a new ROM (some ROMs have it, some don't, but look for Call Settings (by accessing phone icon) > 'Always use Proximity' then uncheck the option).
If problem still persists, then it's possible that it's indeed a faulty sensor (though it seems not the case at the moment). It's up to you if you want to send it for repair/replacement or you can disable it if you're phone is rooted.
Download Android Sensor Box and Hardware Disabler
Run Android Sensor Box.
Choose proximity sensor.
Look for the square icon near the bottom left of the screen, press and remember the proximity sensor's driver name.
Run Hardware Disabler.
Scan or whatever the option is there.
Look for the proximity sensor's driver name then select.
Reboot.
A confirmation will pop asking to disable the Sensor, select yes.
For ROM suggestions (with an option to disable proximity sensor when calling), you should probably asked around on some ROM non-development topics if they have it. Also, check if the ROM is stable to prevent more problems.
My rear camera isn't working properly anymore so I was just wondering if anyone else has had a similar problem so if I can confirm the likely culprit. Whenever I use the rear camera the screen is mainly purple and pixelated and I can only just about see the background through it all.
The front (selfie) camera is fine so I'm just thinking about replacing the camera at the back but thought I'd ask around in case anyone knew of any other common problem it could be in case I was barking up the wrong tree.
I tried to upload a picture of what it looked like but couldn't manage it.
I've watched a couple of YouTube videos on how to replace it and I'm happy to have a go but if anyone's got any experience/advice on that too it would be appreciated.
Thanks in advance.

hi,
I had same problem two weeks ago. Suddently the rear camera gone to pink the frontal was good. After the initial panic, I've tried to search internet, on some forums was said to gently push around the rear lens and the camera will show something. Some one says that use this method pushed firmly around the ring and the camera was fixed, some others no.
In my case, pushing around the camera, initially worked for a couple of seconds, then the image was flickering with vertical green lines, noises, and interlaced "grid" grey scan lines like old videogames. then was hardly usable only pushing around the rim for about one minute for take a normal photo. here is the attachments of panic:silly:
I think the camera was damaged by too much overheat that unglued the backplate, and consequentially the use or some hit or light fall may had damaged the flex sensor or the placement lens on the motherboard. In fact in the previous months i had noticed the backplate was moving if poked with fingers on the edges. I mean gently pressed and the back plate was moving. Doing the pressure factory test, it was around 1020,3-1001Millibar on static and changed when pressed on screen or on the back. I had a dbrand skin on the back and due to the heat shrinked and became smaller. I think the overheat was caused by the firmware updates and some app that sucked away the battery in years. Upgrading from Lollipop, twice to MM, to Nougat, in years and then in the last time some flash to MM and then to Nougat again give it the final hit, especially the first time power up after flashing when you have to set everything from scratch.
I sent it in warranty repair, for camera damaged, added the request to swap battery due to duration (because on June the warranty ends ) and to check and fix the IP68 requirements, also noticing very overheat issues.
Now the pressure test is a solid fixed 999,01-999,03Millibar and the feel is more solid in general when handled. If you have luck when Sony repair it, the screen protector on the front if you have applied, won't be touched, only the back.
good luck
So did they just replace the camera module that is plugged in to the top at the back? (obviously apart from battery too).
Your post seems to suggest overheat which caused motherboard damage too.
Unless I've read it wrong you're suggesting swapping the camera will fix the problem.
I know I'd obviously need a new back cover too.
