This nexus 5 is very interesting.
My 1x in engineering (or engernering) shows no connection until there is a call.
I tried calling voice mail and it would toggle between choosing PCS or ESMR band to connect the call. When the call would end, the 1x connection would drop.
All calls come/go just fine - has qualcomm figured out how to completely kill the 1x radio unless there is an active call? If so, that is impressive! How does it select which band to use when making a call? I was in the same exact spot at 7AM in the morning (low traffic) and one call it would pick PCS, the next call ESMR...
What's also interesting is when I make the call, the LTE icon goes away, flashes R for a second, and then just displays bars (no 3G, no nothing, just voice bars). When I hang up, it goes blank, then goes back on LTE.
It appears the game has changed. I am LOVING this phone.
I still can't get over how great this phone is at holding LTE. It's unreal. EVERYONE on s4gru should have this phone for how great the radio is.
