Unhappy [Q] Proximity Sensor Not Functioning (CM11)

Hi all,

Been struggling with this for the last days.
I have a Samsung Galaxy S3, Rooted, with CM11 for i9300 (nightly).

Everything seems to work properly except for the Proximity Sensor.

When I make calls the screen will go black and won't recover.
Proximity Sensor Finder always show 0.0 cm as if objects are constantly near.

These are the things I tried so far, with no luck:

1. Opening the device and cleaning the sensor.
2. Creating a bolder separation between the two receptors of the sensor.
3. Running Auto Calibration
4. Running Manual Calibration returns:
Code:
$ cat state #finger on the sensor to test if the sensor is working properly
0
$ cat state #blank value
0
Code:
$ cat prox_cal
0,15
Which means my 'new' calibration adds up to '0' which makes no sense (is it?)

What else would you suggest? This is really frustrating

I am also having this issue on my girlfriends T-Mobile s3 (d2lte i think) on CM11 M7-M9. Just now starting to investigate, but I will report back here if I find anything

This app fixed it for me (while others that claimed they should did not). Check it out:

I don't want to use an app, I want to fix the proximity sensor issue.

Any other ideas?

The point is, it was not a problem with the proximity sensor. It was a bug. Try the app, if it works, you proximity sensor is fine.

What settings in the app did you use to test it?

Enable screen wake up, restart on startup, auto lock screen, auto wake up, 2 second time out and status bar icon.

Unhappy Update...

I tried flashing my CWM again and downgrading the CM rom to a stable version (10.2).
Still same problem.

What else can I do? The previous user of this phone said there was no problem (he used the stock rom).

I don't want to install a third party app to "fix" it.
I need a decent solution and a functioning proximity sensor.

You can install the app temporarily, to find out if it is a hardware problem or not. No one can help you until you fully diagnose it and find the source of the problem.
