Samsung Galaxy Nexus running ICS 4.0.4, Verizon.
I noticed that if you start streaming on 1X, the phone never switches to 3G/4G. Or if you start streaming on 3G, it would never switch to 4G. However, if the speed goes down a level , it will drop for let's sat 4G to 3G. I don't have this problem when the app is not streaming. It seems to get stuck on the speed the stream was started and it won't let the phone go up a level even though coverage is available.
