Samsung might possibly release three new Galaxy S9 models next year
All screen, more options.
Almost any new smartphone launch has a regular and "plus" sized product to offer, but Samsung is looking to push those bounds. The company is looking to bring back the "mini" line with a Galaxy S9 Mini, obviously smaller than the rest. Some users are looking for a simple phone, and Samsung is trying to appeal to those users. Samsung has also made a name for themselves after the Note 7 fiasco.
It seems like the S9 models will have an all-screen design like other competitors. It's not Samsung's first time with an all screen display. Nothing has been announced about specs, release, or availability.
