This style of phone is rectangular in shape with no flip design features. It was designed to have the feel of a real phone, both durable and nonsense free. The size ranges in both width and length depending on the model.
This style of phone has two parts, connected by a common hinge, which allows the user to close off the inner face when not in use; thus, the inner key functions and screen are protected.
This style of phone has two plates which slide apart with pressure, unveiling the inner screen and key functions. It is useful for people who don’t like flip phones, but still like the design of having two different interfaces.
This style of phone is a lot like a flip phone, but instead of opening courtesy of a hinge, it has a hinge that allows the user to rotate the top face to the side and up, in order to expose the inner face.
