Even at my home where I would have 3G/4G switching (i live in a extended 4G network area 2 blocks from my work/office) I am 4G 50% of the time with the Maxx. Now with the SG3 I am 4G at least 80% of the time.
My wifes Bionic NEVER switchs at my house 4G ALWAYS. I got fed up with the Maxx for this reason and went with the Samsung GS3 and am very happy that I did.
Now to debunk it was equipment failure with the Maxx......... not only did I have the Maxx replaced for that issue but I have several friends with the Razr/Maxx and they have the same issues to the T.
Hail to the SG3!!!! So far it's performance has been stellar.
On a side note... if I ran speedtest.net app on the Bionic and the Maxx, the Bionic would beat out the Maxx 8 out of 10 times. Even other peoples Razr/Maxxs the Bionic my wife has would smoke them. Now the SG3 takes the top spot and smokes the Bionic. All when on 4G of course.
