Proximity Sensor calibration on LOS (Google Play error -505)

[paulakreuzer]

I think the point is: the proximity sensor tool was designed for FP(O)OS and won’t work on other OSes.
But also issues with the proximity sensor seem to be quasi non-existant on Lineage, so I’d suggest trying some of the “old” solutions and workarounds:

@Simone_Ricotta

Besides a badly calibrated sensor the next most common reason for this issue is dust between the proximity sensor and the screen. For more info check this post.

Cleaning tips:

• Clean the screen of your phone, especially the part where the proximity sensor is (See here).
• If that is not enough open up the phone and clean it from the inside.
• Remove the screen and blow onto the sensor and also wipe the sensor window in the screen assembly from the inside (I used a Q-tip for the window!).
• Check the functionality of the Proximity Sensor with an app like Sensor Readout.

###Workarounds

These should not be necessary anymore. If you cleaned and recalibrated (you may have to do it more than once) your proximity sensor and that didn’t help you may want to contact support.

####Use powerbutton to end call

@AndreasLieser

Go to Settings –> Accessibility and activate “Power button ends calls”. Now you can use the Power button to end calls when you need to.

####Disable the sensor (found by @guillaume)

Disable the proximity sensor by putting a small piece of aluminium foil on it (picture). It makes the sensor feel that there is always light and the screen never turns off.

Then use the power button to switch the screen on and off.
