Samsung flip is a concept cell phone utilizing new OLED screen technology. The screen wraps around the bottom of the phone where the notification bar is located. This helps reduce clutter and keeps the notification bar hidden and off the main screen.
The Flip feature allows you to set your phone up in a number of convenient positions. Use front screen for easy access to all apps or quick text/ e-mail viewing while phone is closed. Different interfaces for different phone positions. Flip outer screen towards you or open phone and set up for the best viewing position.
If it is really useful to bend and flip the phone is a question we don’t want to answer, however the concept is very similar to v-phones (like Motorola Razr introduced back in 2007) which is already obsolete and surpassed by all the flat smartphones with huge display (with no funny flip feature).
