    Solved not solved

    Well I've been playing around a bit more testing to find exactly what it is causing this issue.

    It's system profiles. I use these extensively with triggers so my phone connects to my car, goes on vibrate at work etc. With system profiles active (whole menu turned on) the issue occurs. With the profiles off, it's resolved. It does matter how the profiles are configured (I tested with just 1 profile and all settings on "do not change").

    So this is something for the Lineage OS team to look at and fix in a later build because as it stands system profiles are broken, at least for klte. Does anyone else have a different experience on their device and what device are you using?
