Proximity sensor lags while calling

Hi!

I have Sony Xperia P with latest ICS version (but I had this lag in GB).

When I answer a call and positioning phone in horizontal - proximity sensor doesn't work. But when phone in other positions (vertical, non-horizontal) - everything is OK. I think proximity sensor works with gyro sensor (why???). I also checked it in Galaxy Nexus - it's OK, proximity sensor works in all positions.

PS: Also checked Xperia Neo V - it has this bug.

No. All phones doesn't have screen protector.

Yes. I do flashing with Flashtool (with full wipe) and PCC. Nothing changed. Does a Sony calling app have checks of proximity sensor and gyro sensor together or it's checks only proximity sensor? I ask this question cause Xperia Neo V proximity sensor works identically.

Proximity sensor working OK. Only in calling app in horizontal position - proximity sensor doesn't work (or detection rate is low). Does calling app have gyro sensor checks?

that's odd, repair your phone with SUS and check again
