On MIUI v4.0 2.1.13 when I try to enter the sound settings, the settings app FC's and same goes for the data usage. I can't change notification sounds or turn off the audio click sound! lol any chance of a fix?
For sound settings, go and customize your theme under theme manager by setting up ringtone and notification sounds - other then None. Then you should be able to enter sound settings without FCs. No workaround for data usage that I'm aware of, yet.
