One problem with your latest and greatest hardware selling like the proverbial hot-cakes is the inevitable list of things that are going wrong. One new issue to add to the yellow blotching and screen-light leaking is one of the iPad 2′s FaceTime cameras causing the tablet for completely freeze.
According to multiple people on the forums, the issue appears when trying to establish a video-call using the in-built cameras, specifically – though not limited to – the front-facing unit. The only fix reported is a full restart of the iPad. Not ideal.
It’s speculated that the issue is simply a software one and 9to5Mac expect it to be fixed in a future iOS update, though that doesn’t help you right now should you be one of the 7 people on the planet that use FaceTime.
