Finally received system configuration for VoLTE and wifi calling for US unlocked version Snapdragon. 
Why no wifi calling and VoLTE enabling after update in one UI 4.0 unlocked US? 
When Samsung is planning to give potrait mode option?
Please update touchviz UI for S7E similar as S8 now we are bored from this touchviz UI please update.
Any information regarding OREO Update for S7 edge this year or in 2018 in India??
