Proximity Sensor issues

I have been having a issue lately with my proximity sensor. I know that the sensor is supposed to turn off the screen when your ear is near it in a cale, and turn back on when you move the phone away from your ear. But when I make a call without putting the phone to my ear the screen goes off and won't turn back on unless the other person hangs up or I pull the battery. I thought it was because I removed some programs but I flashed a new rom and it didn't fix it.
Here's what I have on my Defy.
2.31 central europe rom
Milestone overclock 1Ghz 60vsel
Z4root
SU
System Recovery
8GB microSD

I heard of trouble with the proximity sensor before. What was triggering it was the phone was set to auto brightness. As soon as it was turned off the problem went away. You didn't say if you have it on auto, but if so, maybe try un-checking it?

I stopped trying to fix it. I think it may have something to do with my invisible shield. Maybe it's not letting enough sunlight in? Idk, but when it does have the issue a finger wipe across were the sensor is fixes it. Strange....

This exactly is the problem. I have motodefy and had the same problem with my phone after i installed the new otterbox case with the screen protector. Searched in vain to calibrate or disable the proximity sensor but in vain. Finally, I peeled of the screen protector from the top and cut it off just under the proximity sensor. This worked and the proximity sensor works like a charm now. It is the screen protector that somehow interferes with the IR.
Another check could be too see if there is a smudge of sunscreen cream on the sensor or not, rubbing against te cheek could easily deposit a layer that can block IR.

Proximity sensor problems.

Problem solved.

Any screen protector covering it ?
clean the screen.

Re-calibrating the proximity sensor.

Hey guys,
The proximity sensor on my G4, for some reason, causes my phone to turn the screen back off immediately when I try to turn it on in the dark. I took it to Verizon, and apparently they see this very frequently. so they would not just give me a new phone. I do have a tempered glass screen protector on my phone, and it covers the whole front, covering the proximity sensor. Is there anything I can do it solve this, it is super annoying? I basically just have to turn off pocket mode, but I cannot see any settings for that on the G4.
I saw another XDA thread that referenced the At&T model of this phone, they have a number to dial that gets to a service menu, that did not work on my Verizon G4.
thanks, any help is appreciated.

The glass screen protectors should have been better designed. The proximity sensor uses infrared (IR). IR radiation doesn't go through glass. So probably no way to fix it other than getting a glass cutter and removing that section of glass.

This one has cutouts for the speaker, sensor and camera...

Appears the updated version of the Yootech does too... These seems to actually have glass instead of just a entire piece missing above the speaker and sensor.

Well then what it seems like you have here is a proximity sensor that needs calibrating. [emoji6]

Hello to re-calibrate the proximity sensor you must be root and download shorcut master(lite) from playstore open and search for hidden menu and then go to de bottom and click LaunchMiniOS and continue with the original post: http://forum.xda-developers.com/showpost.php?p=63133124&postcount=3

Auto wake/sleep cover

I bought this cover https://www.amazon.com/MoKo-Google-Pixel-Case-Lightweight/dp/B019TOM5PU but I cannot make the screen sleep or wake with the cover.
Is there a setting for this ?

I have that exact case on my Pixel C and sleep/wake work fine with it. Never changed any settings from what I recall.

Is it done with a proximity sensor or with a magnetic sensor? Because my Pixel C has no proximity sensor and the wake/lock feature isn't working for me.
