My camera on "all" emulators work perfectly . I can test record/capture photo/ just review on camera. One minus - if bug with preview (green lines or other similar ) than this not showing in emulator. But bugs with rotation ( when on preview all ok and than click on capture or record video we can see what our screen rotated on 90 degree) can be fixed. Hope it's help :)</p>
