There is a bug in my X7 CFW, the Camera Button is not taking pictures.
(Just looks like its trying to focus... good luck with that on a EDOF Camera :p)
The onscreen button is still working to take pictures.
To fix this issue, install this patch and restart your device:
CamButtonFixX7 for The One X7 v1.1.0
I will reupload a fixed CFW for new users, but basically to fix this bug only, no reflashing is required!
