if you have the Orientation toggle in the status bar pull down, and you toggle it on and off, it works at full speed again
weird thing I noticed. I have the toggle in the pull down shade for a few certain apps, and I almost never ever reboot my phone. So far its been going on 7 days.
still, it shouldnt bog down like that anyways, its weird.
im running 6/01 and the toggle did NOT fix the issue on earlier builds, not in my experience. only on this build does toggling it make it work full speed again. maybe its just my phone
