First, I'd like to start with some introduction about myself.
I'm a 16 years old student, Who doesn't know anything about coding, That's it.
I had this Idea about a improved UI for Symbian or any other Operating System but WP, People kept complaining about UIs of Symbian OS, And because I don't know anything about developing the UI.. I just designed it.
Here's a sample picture of the Main screen of the UI:
Top: Settings Bar
Down: Notifications Bar (the one with the time/date in middle)
Down: Navigation Bar (The logo in the middle is the app menu button)
EDIT: I'll add more details about the UI later.
I don't even know if what I'm trying to discuss with you makes sense or not, but I hope so.
