Razr Maxx is unresponsive as hell since ICS update month(s) ago.

I know this thread is old as well, but I also disabled motocast and it seems my phone is running well. I was having g problems with 4G and literally after disabling motocast and restarting my phone 4G was there like it was supposed to. I'll keep you posted if this fix keeps working.
 
I concur. Unless Motocast is essential to you, definitely disable it.
