Unhappy 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.

MOTODEFY WRITES.
