Proximity sensor issues?


Recommended Posts

My proximity sensor has a strange delay in dialer app when I'm moving phone away from my face. It takes 2-5 seconds to turn display back on after I move the phone away from my ear and I can't end the call during that time, which is very frustrating. Detecting when I put it back near my ear works almost instantly and is not an issue. Testing the proximity sensor in factorykit doesn't have that issue, status of the sensor changes instantly both ways. It looks like some artificial delay in dialer app or a bug in dialer app itself.

Anyone has this problem?

I've also found that using some apps that are trying to do some actions given the proximity sensor status (like pocket detection in button mapper app) makes proximity sensor not working or very unstable in dialer app. Disabling proximity detection in those apps or removing them alltogether solves the issue so if you have any problems with your proximity sensor, try disabling those apps to find out if this solves your issues.

Yes, I can confirm these too.

I have an issue of the display constantly turning on and off during a call with the phone on the side of my face.  It is opening apps and once I have had a constant DTMF tone come blaring through.  It has even turned on the speaker phone and muted the call.

I have had some people suggest this is related to the proximity sensor moving around or possible screws missing for holding the screen on the phone.

I have purchased a Bluetooth headset to get around this issue.

I am still using Android 8.

I have had similar experiences. I normally either use it with a headset or hands-free on a desk though, so rarely I use it as a classic phone next to the ear.
I have installed an app to automatically detect to switch to hands-free, and actually thought it was the app that was buggy, but could be something with the sensor-driver...

I have the same issue, which is really frustration. 

When on a call to customer service or something, and they tell you to press "1" for this or "2" for that I often fail because of the time it takes for the display to get activated. same behaviour in stock, Lineage 16 ans AICP
