@McKhan i purchased my unlocked note8 from hong kong last year. after extensive research, i came across shortcut master to modify IMS settings to enable VoLTE/video calling and i was happy. this has been working fine with Android 7. i have been reluctant updating to andorid 8 since its release back in May due to issues (mainly battery) reported by other users. i recently updated to android 8 in order not to fall behind now that android 9 is the latest OS. needless to say, shortcut master no longer works and i was not able to enbale VoLTE/video calling. this has been very frustrating to say the least. i refuse to flash the rom to root the phone just to enble features that should have been there for all phones (locked or unlocked). we bought the oneplus standalone (not from the carrier) and VoLTE works just fine. my next phone will not be another unlocked samsung phone if they refuse to resolve this for their customers.
