Screen goes Dark just after dialing

Hi guys,
I've been using ms2ginger 4.0 and just changed to CM10 by Quarx.
The problem is that as soon as i dial a number the screen goes dark and i could use the power button to display the screen in ms2ginger but not in the cm10 edition.
It happens atleast 9 times out of 10.
Any solution, is the screenguard culprit ?
or any fix for the sensor to work properly?
it was wrking perfectly when used the official froyo!!!

I'm on CM9 and there is a setting under "System Settings > Display" which says "In accurate proximity". See if that's in CM10 and works for you.

Thanks for your reply, in cm10 couldn't find that option moved to cm9(mig edition)
the problem is still there after checking the proximity option but not that much

Found a Solution
I was searching all around this place.
Found a solution that the screw just behind the proximity sensor (when you open the back panel) was a bit tight, too much i guess, just loosened that screw to a single round and it is working perfectly.
Maybe help anyone facing the same issue.
P.S. i did open my whole phone once and i guess tightened the screw too much.

LG G2 D802 brightness issue

Hello guys, it's been two days since i had a problem with my lg g2: in few words i have the brightness blocked at the lowest level. Brightness sensor seems not working, changing brightness in display settings doesn't change anything. I have Grola rom installed (or simple rom) v1.2, twrp, kk bootloader. i tried installing different roms but the problem persists. Any suggestions?

Please any suggestions?

If in warranty please consider to take it in service. If problem not solved changing roms then there's a hardware problem. If not in warranty you must change the sensor in some way. It might be attached to the screen or to the motherboard. First you should try some app (if any): https://play.google.com/store/search?q=brightness adjuster

I tried almost EVERY app to adjust brightness but nothing, still dim screen. I also tried apps to test sensors and the brightness sensor is working.

Problem with the light sensor and gyroscope

hello, I come to you to present you a problem I encountered with my s7 edge .
Three times the brightness sensor stopped working . I also noticed that when I encounter this bug , the gyro sensors no longer work either and It's impossible to get the phone in landscape mode .
In the application cup- z no sensor is detected.
After the device restart everything is back in order.
Someone already encountered this problem ?

Next time to test the sensors dial *#0*# in the stock dialer app.

Hey, thanks for the tip !

Any resolution? This started happening to me too, and nothing seems to fix it. I loaded the U rom, factory reset to the verizon rom and no dice. Samsung will replace my phone, but then I'm out a phone for 2 weeks and my screen protector.

Sensor not working anymore

Hi, anybody can help me, my yd201 proximity sensor not working, i did everything flashing all rom on the forum to try fix this but it still doesn't work. (from 4.+ to the latest MM) with all firmware. i just trying full unroot my phone on root apps then wanna clean system apps using twrp so am try deleting root forder from latest twrp to clean everything, now proximity sensor not working what ever i do rotate, calling, and the biggest problem is back screen is not working too,. download sensor test from the market is working too(device sensor hardware not support on this phone)

Open the phone dialer and dial *#*#4636#*#* , if it doesn't work the first time try the code again and it should open the hidden testing menu, choose device test and you can manually test all the phones sensors to confirm if the proximity sensor is working or not. I had a s7 that did the same thing, the proximity sensor just quit working one day and I confirmed it wasn't working with this method. Good luck.

same result, not working too.
maybe problem is from hardware,
any idea on how to fix it, just something like using xposed or what?

I just dealt with it, sometimes it would work and sometimes it wouldn't. There's an app on the play store that you can use for screen rotation, I ended up using that when I absolutely needed rotate the screen.

i dont care about rotation screen.. i just want the back screen working normally, if tap transfer button on color display it won't open it on epd screen when i rotate the phone..

I don't know if it happened the same with you, I own a YD206 so I am not sure how YD201 behaves, but there's a problem with proximity sensor that makes it working all the time, I have wrote a comment about it and will try to contact Yota about this, meanwhile it would be important for people that are not aware of this problem because is such a faint light to actually confirm if the same is happening to them, YD201 or YD206:
I discovered that I also have this problem, I was with the wrong radio, had to flash the Chinese radio and it suddenly appeared, this is what I have found I have an YD206, so I wonder how the YD201 behaves:
On YD206:
With wrong radio. radio (Russia xx versions) on YD206 , in KitKat or Lollipop ROMs the proximity sensor is OFF by default BUT, as soon you turn ON an app that uses it, it won't turn off again, it keeps blinking even if you force kill the app that started. However it will turn off if the screen is off, after 5 seconds after. Also it's important to acknowledge that 2G only with this radios fails. On Lollipop Wifi won't turn off automatically, just manually.
YD206 With the correct radio. radio S01_003_3034_CN1_M05 2G 3G (UMTS) and 4G (LTE) all work and with better reception, but as soon the screen is ON, the proximity sensor starts working, does not matter what app you have open, when you turn OFF the screen the proximity sensor will turn OFF in about 5 seconds. If you are using the EPD screen the proximity sensor will turn OFF faster than 5 seconds, but as soon you touch the EPD it will turn ON for 3 seconds or so. On Lollipop Wifi won't turn off automatically, just manually.
So the problem acts differently when you flash a different radio, I am not sure where's the bug comes from, but it seems there's also a bug with YotaRom. There's a Xposed module to disable proximity sensor in specific apps, I haven't tried that, I also would like to know how this behaves with the Marshmallow Beta.
(For the ones that are not aware of this problem, keep in mind that to see this problem you need to be on a dark place to see the very faint red light of the proximity sensor.)
Best regards,
This problem is also being discussed here: https://forum.xda-developers.com/yot...tive-t3520013/

Proximity and ambient light sensor stopped working!!!

I don´t know if it´s a coincidence or not, but I a few days after the update to Oxigen OS 3.6.1 I noticed that the proximity sensor and light sensor of my ONEPLUS 2 stopped working.
I used AndroSenor and Sensor box from the PlayStore, and both os them say thar the proximity and light sensors are missing.
I had a remote session with a ONEPLUS L2 specialist and they wiped my phone and reflashed the latest ROM (ver. 3.6.1), but the problem wasn´t solved..
I guess that, if the sensors don´t appear in the apps I mentioned maybe it´a a hardware problem, but I would like to hear more opinions.
If anyone has any suggestion to try to solve this problem before sending it to repair (out of warranty)??

flash persist.img from fastboot
backup all your info
in some cases it will help

hi there!
I seem to be having quite a similar problem, though, my sensors work, but stop responding after an unspecified period of time (can be anywhere between minutes and hours).
I tried flashing several roms (oreo, nougat) and yesterday i flashed Oreo Pixel Experience (just pure ROM+OP5 camera, no root no custom kernel just to rule out a few things) but the issue remains. Important to mention, i always clean flash.
The best way to describe the issue is: "sometimes the proximity and light sensor just stop working and i dont really know why" which is obviously causing a whole bunch of issues with auto brightness, making calls, picking up when someone calls etc.
The thing is, everything works after a reboot...but only for some time...then the sensors go "offline".
sometimes they work for a couple of hours, even a day...sometimes they die after half an hour or something. I have a feeling that i see them die faster when i have my phone in the pocket and leave it idle for a while, and when i use my phone often and dont really give the phone time to rest they live longer. It almost feels as if the phone goes to some deep sleep when idle for some time, disconnects the sensors, but doesnt turn them on again when woken up.
tried flashing the persist.img as advised just above, but it doesnt seem to have an effect.
anyone has any good idea?
thanks!

allright, being desperate from not being able to use my phone in a normal way i flashed OOS 3.6.1 from official zip files that can be downloaded from oneplus.net support section, using OP recovery and surprise surprise - sensors are working flawlessly! so im ruling out the HW problem. I think im going to stick to OOS for a while to monitor the sensors and eventually im going to try flashing oreo again.

ok, last update from my side: after two days on OOS where everything worked fine i flashed Pixel Oreo build and sensors continue working just fine! so, whoever is experiencing strange behavior of his sensors, i recommend the same approach.

You still have working sensors?
I have exactly the same behavior as you mentioned in your first post. FRUSTRATING!
I've tried flash lineageos 15.1 ROM, no luck. New persist.img from official fastboot oos ROM but no luck either.

Hi! Yes, my sensors are still working just nicely.

So good for you ?
Before when your sensors struggled, did they also disappear from any sensor test app. Or did they just not work?
My prox sensor did not disappear but just hangs at 0 or 5cm if I check the value in any sensor app. And light turns 0 Lux also.

I've similar problem. Went completely stock as suggested but the problem persisted.

Well mine didnt really "dissappear" either. They "froze" too. Lux froze at whatever value it measured the last however i am almost certain it was never exactly 0. Prox behaved the same as you describe: 0 or 5.

Interesting. I'm going to flash OOS recovery and latest OOS ROM later today and give it a try.

My lightsensor always freezes at 0 Lux. And when the prox freeze at 0 its impossible to quit a call. So f*cking frustrating so I have to fix this problem ASAP

I have the same problem with my LUX device, sometimes the sensors work randomly. When I reboot my phone the sensors stop working. The screen does not rotate, the most interesting thing is that it did flash the Moto camera mod and the rotation works perfectly with the camera, with the stock camera there is no rotation.

UPDATE:
I scheduled a remote session with Oneplus L2 Team and they performed a full factory reset of all partitions. No luck, problems still persist.
It must be a hardware problem.

In my case I sent the smartphone to them and they said it was a problem with the motherboard.
