The Galaxy Z Flip series typically features smartphones with a foldable design, allowing users to fold the device in half for a more compact form factor. These phones often have a clamshell design with a flexible display. Key features may include a high-quality AMOLED display, a powerful camera system, and specifications comparable to other flagship smartphones in the Samsung Galaxy lineup.
