You keep insisting about a thing that is clearly not included in the Rom. Lee uses HTC Dialer and nothing like what you are describing. Just take a nandroid backup, clean flash the Rom and if you still get that, then we can talk again.
Cripes why does anyone use that app? If you want a proper serious root file manager, the best and always has been is ROOT EXPLORER. Well worth the small fee.
Why does Google Play say this program is "not supported on your device"? How can I enable premium features?
That shouldn't be happening, I will take a look.. but no, none of the settings require premium
