I have the Unlocked version of the Samsung S20+ (SM-G986U1 model) in Software Information, the Server provider SW ver. is SAOMA_SM-G986U1_OYM_VZW-QQ-0027.
I've never seen a 5G indicator. I read somewhere where unlocked versions of the Samsung phone may not get the 5G software. I would be surprised as this is probably the primary purpose to get one of these phones. Is the Unlocked version just getting the update later?
