The brief of this project was to create a brand new Mobile OS design. Given below is the design for minima, a non-existing, minimalistic mobile OS. 

Creation:

The OS is created for minimalists or people who prefer a clean, organized and minimal mobile OS. It is customizable to the extent of choosing between solid colors for the palette and grouping external icons. 

The lock screen can be opened with a fingerprint scanner. 

The home page has a display of 3 icons at the bottom which can be scrolled to the right or left to reveal more. On pressing a main icon, sub-icons appear, under which are options related to the corresponding-icon.

Therefore, all internal apps can be accessed on the home page without going to a separate app. 

The external apps can be grouped as categories which are displayed on scrolling right at the home page. The widget drops down from the right instead of from the top.
