Can someone with a 640 dual sim unlocked confirm that the messaging, calling, etc is all working as it should for the dual sims? This is my travel phone and I want to be sure the dual sim functionality is working well before going from 8.1
Thanks!!!!
EDIT: Well screw it, I figured to just do the upgrade after making a fresh backup. I'll post back after and some testing...
