4G advance, as i m also using Lenovo P2, when i switch my maxis sim card , its shows 4G+ but in RN4 it dors not show
this one, i am not sure. sometimes it depends on the phone's firmware when displaying the icon. it could be latching to 4G Advance signal but only display 4G icon.
only way is to test and compare the speed throughput.
same location: Lenovo P2 + Maxis @ 4G+ signal icon, note down the speed.
same location: RN4 + Maxis 4G signal icon, note down the speed.
if RN4 speed can achieve similar throughout as from Lenovo P2, then most likely RN4 can accept 4G Advance signal.
just a suggestion.
