Hey there. I'll just assume you're using a stock rom, and I'll asume it (your light sensor) is actually broken.

"Repairing" it wont be cheap, because it's part of the flex ribbon/cable assembly, which also holds the front camera, notification LED, proximity sensor, home button, display/touchscreen assembly connector and speaker pins. Pretty much everything is soldered to this component.

There *could* be a problem with your flex ribbon. Perhams some of its wires are starting to break? I know this can lead to all sorts of issues, because it started messing with my LED some months ago. But, on the other hand, it might just be a faulty sensor.

Whatever it might be, I say you leave it as it is. Replacing the flex is no joke on the XMP.

Ebay
Search on ebay for "flex cable sk17i".

Before disassembly please make sure that the cable you will receive has all the sensors and the camera. The first time I purchased such a cable, it came without proximity sensor... Unfortunately I cannot upload pictures or links, but google is your friend, right?

If I were you, I'd look for a flex ribbon with the "1241-7544" part number between the big gray square and the display port/slot. Genuine parts WILL have this number, cheap knock-offs don't (at least most of the time).
