I agree My G2 holds lte well even into the -120 db range. The only issue my g2 has as far as lte goes is switching from 3g to lte while in use. ie if I am driving streaming music or letting my son watch youtube. The only way to get it to switch bck to lte is too recycle data and or stop the application.
However, this weekend I drove around to two sprint stores and help my phone next the the other triband devices G4 gmin, One mega, and N5 My g2 help a better db than all except the n5 but differnce was only like 1 db I made sure both were on the same tower using signal check.
I did not compare any single band devices.
The issues people are having with their g2 must be a bad batch or coverage area combined with tri-band newess bugginess
