Discussion: My Phone App keeps Opening

My Phone App keeps Opening I've seen on some other forums this issue but the fixes don't seem to apply to me.

The issue is that any time I install something, the app closes and my phone application is open. It also happens seemingly randomly when not installing things, but mainly after an install. Some have said it's a phone-lag problem (can't find the reg keys to edit to fix) and some say it's got to do with Pocket Toolman2 (I do have this installed).

Does anyone know of any fixes or how I can get it to stop opening all the time?
