Anyone else got the same problem?
Well, not to surrect a year+ old thread, but my L640 has encountered this same issue. Looks similar in color, but its shape is different, and it's near the volume rocker on the right side of the screen. It may have been there, very faint, for some time. Yesterday, I was outside and my phone was inside my bag, and the bag was in direct sun for a few hours. When I would take out my phone to check it, it was very noticeable. Yesterday was the first time I had noticed it. Now that my phone is back to normal operating temperatures, it's barely noticeable.. My 640 is nearing a year old. Would love to know what causes this...
My phone has been through a few drops. =-x. It also has gotten quite warm in the sun a few times..
I'll take a pic the next time I see it and have another cam ready.. (I'm not gonna heat up my phone intentionally to see if it reappears.

)
