One issue I seem to be having is Vignette seems to cause the phone to reboot if I try to take a picture. Is there any fix for this or am I forced to use the blur camera app?.
That has nothing to do with Rubix or GB. It was a problem with Vignette on the new GB leak. They just updated the app which fixes this problem. Download the newest release and you'll be good to go.
Awesome, thank you!
