Not really. I'm completely solid on 3G. The issue is on 4G the 4G and bars will go white because they lose connection with the Google servers dropping the 4G data connection. Not sure why the phone has to be in constant contact with Google just to have a data connection but oh well.
It has made 4G completely unusable. I've actually had to set my Bionic to only see the CDMA 3G network and ignore the LTE network and shut off the LTE radio. Rather depressing when I'm in a 4G market with a 4G phone and I can't use 4G.
