Process com.android.phone is not responding

Hey all,

I've searched high and low for a the solution to this problem, and have found nothing. I've tried several different versions of dualboot Androids on my M8SE 8GB, but I always end up getting this message during my phone calls. Answering phones calls is quite sluggish, and often times, I get this error message before I can even hear the person on the other end:

"process com.android.phone is not responding"

I'm then given two options, a) force or b) wait.

Has anyone else in the community found a solution to this?

Thanks!
