If you're still experiencing the issue, I am making the assumption that you have an international LG G2 (D802) so you should try and diagnose the issue as you said by looking at some sort of log or even a test. Open the dialer and type this string into it and a service menu should appear. 3845#*802# After this, click on "HW Device Test" and then "ALC ...

After updating to 5.0 lollipop today, again checking with CPU-Z, the sensor does appear to be working properly. Most of the time it changes from 5 - 0 within a second, there are a few occasions where it takes maybe 2 seconds. Looks like this was a software calibration issue all along - strange why it only recently started happening though...?

Use "Screen On Call" app to keep screen on during call. There is no need to turn proximity sensor off. It will keep working and if you move you phone to your ear, screen will go off, but if you keep it on the table or away from any blocking objects, screen will stay on, so you will be able to use keypad to punch more numbers or for whatever reason you want ...

This is a yes or no question so the sensor doesn't have to be able to measure the distance, there just has to be a designated ...

Feel free to correct me if I'm wrong, but as I understand it, the proximity sensor is what's used in call to stop your face from providing unwanted touch input. It usually glows red while activated and emits infrared. The light sensor is what is used to measure light levels for things like adaptive brightness.

mobile phones use IR-based proximity sensors to detect the presence of a human ear. This sensing is done for two purposes: Reduce display power consumption by turning off the LCD backlight and to disable the touch screen to avoid inadvertent touches by the cheek. IR sensors have a number of disadvantages, including high power consumption, high cost, blind ...

Try this: turn off the phone, then press volume up + volume down and power buttons for a while. It will show 2 options, recovery mode and factory mode. Select factory mode and there you do all tests and all your problems will be solved.
