[Q] proximity sensor problems

Soo.. it started a while ago, i switch roms alot and i am very cautious when it comes to kernels and i try to flash the right one every time but with the S-ON limitations it has been some kind of confusing
to be exact, i flashed the pokemon rom with the kernel impeded through fastboot
and the proximity sensor is not working (not turning the screen off during calls)
and i flashed bricked, faux and franco's kernels and still its not working
and no its not physically damage because i had IC rom before it and it was working fine
does any one know what is going on, what i might be missing or something i could try
anything will be helpfull
Cheers

i installed an app called AndroSensor and it said for the proximity sensor check "faliur to start" and then after a while "waiting for event"
if that might help
and the light sensor is "waiting for event" too

well i solved it.. i dont know what actually happend but here is what i did
first i tried to flash the new franco kernel along with its modules and it didnt work (didnt boot)
so i thought to try not just the stock boot image (as it is provided in the pokemon flasher) but also the stock modules (as i dont own a widnows i cant just run the script file)
i unzipped the franco modules, replaced it with the stock modules and repacked it, flashed the stock boot.img in fastboot, flashed the repacked modules from the recovery and i got the proximity and the light sensor working again

could you please help me, my proximity sensor is not working at all...and i dont know why, i changed the kernel and the modules and it havent come back..., the light sensor is working well

I have the same Problem. Light Sensor is working. Proximity Sensor suddenly stopped working. There is no reaction when i use z-device test. The weird thing is, it passes the HTC function test and the red light turns on when i try to get a reaction of it in z-device test. It seems to work somehow but is not reacting to movement. I hope there is a fix for that. I don't want to send it in for the 6th time.

So it seems that my proximity sensor is not broken. It just needs very high brightness values to work. So in a dark room it won't work. Is there a way to calibrate the proximity sensor?

Even I have the problem of non-operation of the proximity sensor and light sensor lenses. After various tests and seen several videos, I realized that the problem is in contact with the sensor to the motherboard. Pressing close to sensors, close to the camera (back) everything returns to normal ...
Sorry for my English ...

I know this is an old thread, but I'm having the same problem as guistanca. Thought it was broken, but squeezing the phone made it burst back to life... dodgy?

Same problem like giustanca and peedub, any ideas,? It is hardware issue or it can be fixed by some software modification?

Ik have the same problem sinds a month, pressing the screen on the upside wil help to get the sensor to work again.
For me it's a hardware faillure i think.

Exactly my situation but when I press screen on the upside it help but just for I whine, few second and sensor didnt work again. I will wait for new official Jelly update 4.2. and if problem will be still remain, probably I will send my One X to service.

Problem with Proximity sensor and Network Issue on note 2

Hello Guys,
I'm facing issue with my Samsung Galaxy Note II proximity sensor and Network Issue on it,
Network Part:- First of all it was working fine, after getting patch for KitKat 4.4.2 and installing network issue arise, like suddenly i'm not able to make call's or receive it or even unable to access 3G internet on it, it will show 2 tower on device and "H" symbol but no calls will be done or receive it, while network goes unavailable.
Proximity Sensor:- Proximity sensor is not working properly from last 15-20 days, I tried resetting device, blowing air on sensor on whole device, executed few application gyroscope explorer and few other, but issue still persist.
Today I came to know, when I press front camera part or near to it, then proximity sensor is working fine with out any for a while, then again I need to press it near front camera.
Thanks waiting for your solution's....

Did you managed to get a solution for that!

just replace proximity sensor, it's cheap and helped me to solve similiar issues. my sensor got stuck in one position, sometimes was ok, but now it's working very good, paid 6$ with delivery. easy install

Appreciating your feedback.
It would be great if you explain a little how to install such part! And from where I can buy it.
Many thanks for your valued support.

Proximity sensor is buggy, can't find a solution.

Hello,
I bought a Redmi 1s online and from the very first day, the proximity sensor doesn't work well, whenever I made a call, after putting the phone near my face, the screen goes dark as normal but it sometimes just won't turn back on. I tried calibrating it through *#*#64663#*#*, I was able to calibrate fine 2 times, but after putting a screen guard on, the sensor became buggy again.
*I've tried flashing different ROM's which doesn't help
*I've removed the screen guard and still buggy
*I cannot calibrate the sensor anymore and just fails
*I've tested the sensor with a 3rd party app from play store and it seems to work fine in that app.
I'm currently out of ideas, can anyone help me?
PS: Sometimes, the screen goes off right after hitting the call button and wont turn back on until the call ends.

Yes problem with proximity sensor was their and because it was on base rom so it reflected in other roms too. Currently i am not experiencing it in miui 6. So either try miui v50 (Latest official stable update) or try miui 6.
Again its a software problem and will be solved.

Wake up problems after flashing AOSP 6 - E975

PROBLEM
After flashing to AOSP 6 I have problems with waking the screen up.
1. After or during the call
2. After longer sleep
It can take up to a minute to wake up. Usualy around 10-20 seconds after multiple presses (single press can sometimes doesn't wake the phone).
NO PROBLEMS WHEN:
1. I manualy sleep the screen, and press power again after a moment - I can bring it to a wake up state without any problems.
2. If the phone is connected through USB - there is also no problem to instantly bring the wakeup screen.
3. There is also no problem to bring the wakeup screen with adb
Code:
adb shell input keyevent 26
I was expecting it to be some sort of sensor problem, as it persists to other roms, even coming back to 5.1.1 which previously worked flawlessly in this department.
I've tried this: http://forum.xda-developers.com/opt...mpting-to-fix-broken-sensors-mm-e975-t3297566 without any results. I've also tried restoring factory settings.
Any ideas?

What does CPU-Z think of your sensor data? it's being represented correctly?

The sensor as far as I know is binary, so either something is in proximity or not, and as that it works correctly under any system.
After reverting to stock 4.4.2 the problem does not appear.
Installing AOSP 6 again - the problem returns.

well, i don't really know, my proximity sensor has been working well since first time i went 6.0 AOSP, even when no other sensor was working at all

Honestly I don't know what is the problem, but in every thread concerning wakup issues and E975 the sensors are blamed. The physical sensor is working properly as I am not having any problems running stock 4.4.2.

Question Fingerprint Calibration tool not found

I have replaced my screen and fingerprint reader is not working.
Using the google tool, I can connect to my phone and search for fingerprint recalibration software
I click install software and receive this message:
Couldn't find the unique calibration software for this device
How do I get my fingerprint reader working again?

Several other users in this section found out the hard way that they have to get the fingerprint reader replaced at the same time as the screen.

Hi! You may have already located answers for this, but I can tell you that this happened to me a few months ago. I did not know that replacing the P6P screen resulted in loss of fingerprint sensor functionality. You won't have your fingerprint sensor back as that calibration tool doesn't seem to fix the problem.
However, there is an excellent solution called the Universal Face Unlock (search it here on XDA) which I installed, and it works much better than the fingerprint sensor did. I'd say it works about 90% of the time (dark or lower light not as well) but it is a great work-around! Give it a try
