Samsung Galaxy J7 Duo update brings AR Emoji support, November security patch
Samsung Galaxy J7 (2018) is already available for purchase in the United States, although the update released recently is aimed at the dual-SIM version. Even so, there's a high chance that the single-SIM variant will be getting the update as well.
Speaking of the update, it's not just the AR Emoji feature that is included in the new firmware version J720FDDU3ARJ3, but the latest November security patch as well. As SamMobile points out, the update weighs in at 480MB, so make sure you have enough storage space.
Although there's no guarantee that AR Emoji support will make it to other Galaxy J series smartphones, it's nice to know that Samsung is trying to bring premium features to cheaper devices.
