Alleged Samsung Galaxy S5 screenshot shows new TouchWiz UI with round, flat icons29
You can clearly spot the ‘Outdoor’ and ‘Curiosity’ icons that Samsung teased, and in this screenshot those seem to be related to positioning and discoverability, accordingly.
This radical change in TouchWiz might be the big surprise from Samsung at Mobile World Congress. The company has been criticized by many for its TouchWiz skin that takes up a lot of storage space, features many gimmicky features, and comes with a bit too cartoonish looks. Samsung might just have decided to overhaul it completely.
The first hints of the Samsung Galaxy S5 have also surfaced recently, with dimensions claiming that it’d have a slightly larger, 5.24” display, but retain almost the same size as the Galaxy S4 thanks to narrower bezels.
