New guy here...very close to getting 7+. From reading this thread, it seems (to my untrained eyes) that 7 has Qualcomm X12 LTE modem, right? It can do 2 CA up and 4 CA down. IF so, does FCC say if it has 4x4MIMO antenna? (I am asking because my brother is interested for ATT and Tmo.)
Thanks in advance.
