Hi Goonj, welcome to the community!

I suggest running a diagnostics test on the proximity sensor of your device, there are two ways you can do this.

One way is by going into the main Settings > About phone > tap Diagnostics > tap Test > choose Ear proximity. The other way to do so is to dial *#*#7378423#*#* into the phones keypad and there you can tap Service tests & then tap Proximity switch. Report back to us with what you find.

Hi Goonj, glad to hear that. So to confirm, when you are not covering the sensor it is not detected but when you cover the sensor it is detected? Or does it say detected no matter what? Also, is there a screen protector or case on your device?

Yes when i don't cover the sensor its not detected but when i cover the sensor with my finger it shows the message as DETECTED. Also i have put a screen guard on my screen. I doubt if the problem is due to screen guard.

Hello! My sensor does not seem to work properly ever since I bought M4 Aqua Dual phone. When I do the proximity to ear test, the vibration starts immediately. If I understand correctly, it should only start if screen/sensor is covered. Covering/uncovering front screen does not change anything, vibration continues unabated.

I have trouble taking calls, the screen sometimes remains black and I can't take call. Also it does not light up when I take the phone away from my ear.

I did not put any screen covers on my phone, but I am starting to worry, how do I check to make sure there is no factory screen cover??

If this is not screen cover, then what should I do, do I need to take it to service center? Or should I try the PCC thing first?

Regards,

Valentina
