Well, the camera is not so good compared with Nokia Lumia 920, even with iPhone 5 and Galaxy S3. Just as Gizmodi write:

The Z10 didn’t even hold the dimmest, most-pathetic light to the other cameras in our test. Look at that photo above on the left. It is an abject and miserable failure. Because this is a particularly difficult shooting setting, all of the photos have problems with noise, distortion, and detail, but we’ve haven’t seen something so crummy as the Z10 in a long time. The Z10 even has a "night" setting that was completely useless. This is some four-years-ago crap.

Anyway, whether Blackberry can make it. The market is just the answer.
