I just purchased my Q10 on July 25, not even a month ago, and I've been experiencing intermittent colored stripes, like a test pattern, when I select the front-facing camera. It doesn't happen that often, but when it does, it really "ruins the moment"! Rebooting phone does not help! Then some days later, I'll just 'test' it, and it's working properly again. Now it's been stuck in the colored test pattern mode for a few days again.
I'm past my two-week return period. Is anyone else experiencing this problem?
