I sell my Sony Xperia X (F5121) in the color white. It is in very good condition. A crack in the glass from the headset to the edge is a visual defect, but no danger. I can send pictures if interested. A clear cover protects the phone. Currently has Android 8.0.0 installed, but it has been used with Sailfish OS.
I am selling as I no longer have any use for the device.
