I've used a rom on my old phone that had a lot of FC issues that were in the settings so I'm really patient with this, most of it works. It's anything that involves a slider actually. Volume, brightness, and also when I click "More" under network settings. But I always have triggers on my Launcher so I barely go on the settings menu. I'm using the R800x.
