UX&UI proposal for a REF screen interface.
This is how I built up initial lo-fi interaction concepts.
Define challenge
From research, we found users have problems with navigation.
And more than 80% of users answered they won't pay more for the smart features.
By re-defining the information hierarchy and the way it shows, we could solve the issue.
This is one of lo-fi prototypes I made in the process.

Information architecture
Basic architecture is built to help users easily understand and access key features
Features were selected and re-arranged  according to below criteria
- GNB -
- Optional Informations -
- Key values -
most used features
 Brand value & product USP
Killer feature (wow factor)
Layout
I calculated screen surface share of each section.
and placed them according to 
Interaction concept
lo-fi prototype
These key 3 features are directly accessible within one tap, wherever a user is. 
And linear flow of UI motion is giving hint to users how to access features.
