Peace, mercy, and blessings of God be upon you. I have a Samsung Galaxy Z Flip 4 for sale. The back of the device is completely transparent, it is the original glass of the device, but the color has been removed from it and the device was closed by the Samsung agent. The device is working, no problems, but the external screen (the small one) the touch does not work because of the cable. The device has a storage of 256 GB and its original color is black. It is suitable for use or display. Contact via private message.
