John 14:6 "Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me."
Also, you're incorrect about the Nexus showing it's 4G signal. It's the only phone actually showing a true 4G signal. When I set my Nexus to 3G I get a significantly lower dBm than when I set it to 4G, which means it's correctly showing both signals. 3G signal will be better since the coverage is much better and bug free.
