Four keys get you almost everywhere.
KROMA behaves like a physical phone: move, choose, go back, repeat.
Move
Step through menus, lists, colours and scale values.
Select
Open a menu item, confirm a choice, save or start.
Back
Return one screen, cancel a preview, or pause a game.
Shortcuts
Open root-menu items quickly and control pocket games.
From the Home screen, press Menu or the left soft key. Use ↑/↓ and OK from there. Hold C for about one second to return Home from most screens.
On a two-way rocker, use 2/4/6/8 for precise four-way game control. GAMZAG also maps W/A/S/D/X to Up, Left, OK, Right and Down.
Change the whole phone in under a minute.
The model controls the handset shape. Every model has its own colour list.
