What app is that shows you that info?
My guess is that he is also using the LTE Discovery app?
Where does it show b4 in this?
*#*#4636#*#*
in dialer this is the only hidden menu I can access but still it won't connect to b12 I tried bunch of stuff and still nothing. On verizon it switches between b13 and b4 fine,with tmo stays on b4.
Band12 works already for me had to restore to stock and other stuff. All is good as of today.Are you in a Band 12 area? From my understanding it will only connect to Band 12 when it needs too (not sure if you can force Band 12). Band 12 is slower than Band 4 from what I have heard.
