Samsung Z Flip 4. The phone's screen is broken, meaning when you fold the phone and then unfold it to be flat, it doesn't work and freezes, and the screen works again after a while. This is the only defect with the screen. Everything else is working. The screen repair is approximately 700. Meaning, if you keep the phone flat without folding it, it works.
