Anx camera - i have no idea.
For double tap, try resetting rros setting (click the plus symbol in the resurrection tools). The bugs pop up when you tinker alot. If you don't customise the bugs go away. But then, what's the point of resurrection remix.
This rom has many bugs but i don't know how to report it. (No offence @letsmakecakes, really love your work)
The only thing keeps me to this rom is battery life.
And its customisability but ?.
