Samsung Galaxy Z Flip4 256GB

Galaxy Z Flip4 256GB Graphite SM-F721U1
One year old, selling as I've got a new phone.
This is a great phone that works well. It has a small crack on the back (see photos) that has no effect and can't be felt in the hand.
Also an issue where the screen turns off in folded mode. It will fold part way and then the screen shuts off until opened again. Suspect it's the opening sensor but as have a new phone never got it checked. This is why the very low price, someone will have to take it in for a check, or use it open mostly like I did as it works perfectly when open.
No guarantees other than that the phone is as described and sold as such
