The latest flagship Samsung smartphones (Galaxy S20 line and Z Flip clamshell) came out not only with Android 10, but also with the One UI 2.1 shell. Compared to the One UI 2.0, it has a number of very useful innovations. For example, the Quick share function, which simplifies the process of sending large files to other devices.
Fortunately, at least the flagships of Samsung 2019 and even 2018 will later receive updates that will bring them the One UI 2.1 shell. These are the Galaxy S9 and Galaxy Note9 lines, as well as the Galaxy S10 and Galaxy Note10. Unfortunately, there is no data on when this or that model will receive an update, but the fact that these smartphones will update is already pleasing.
