I found these apps that were restored from my wp8 backup but were causing my 950xl to be unstable. I discovered they were problematic because storage manager could not move them from SD to phone internal storage:
DualShot
Hilton HHonors
Vevo
Zuma's Revenge
There may be more, try moving your apps to find bad ones between SD and internal memory in storage!
Uninstalling these apps resulted in much more stable everything.
