A lot has changed in the mobile industry over the past decade. Handsets now only have physical buttons that are absolutely necessary. Manufacturers have also gradually increased the screen size of their devices.
Galaxy's UX journey to One UI
We have seen the Galaxy's UX evolve during this period. The first edition of Samsung's premium Galaxy S phones brought the Quick Panel for easy switching between apps. Then came the Live Panel with the Galaxy S2. Another major UX change came with the Galaxy S6 edge where Edge panels were utilized to take advantage of the display curve.
As display sizes continue to increase, Samsung is future-proofing its UX with One UI. It has been designed for easier one-handed usage and improved productivity. One UI also brings a system-wide Night Mode.
One UI is certainly why Samsung fans are waiting for the Android Pie update. It's already out for the Galaxy S9 and Galaxy S9+. Samsung is also rolling out the first stable Android Pie build for the Galaxy Note 9 today.
