Since 2018 I have seen that the Samsung has never fail to surprise the generation with some new features in every model they launch, at the same time they launch every model in a series type. For example: M10 to M10s, M20 to M20s and so on. Then! "Why not try to upgrade Samsung Galaxy A7 2018 to Samsung Galaxy A7s 2018 or Samsung Galaxy A7 pro 2018?"
