Sony RX100M4 Defective Please check out the following

Sony RX100M4 for sale. The viewfinder and flash are broken and the E:91:01 error keeps popping up. Also, the lens ring is stiff, so I can rotate it but it doesn't turn well in some areas. Other than that, it shoots and functions fine. I bought it broken, but it didn't bother me too much to take pictures. Here are some photos I took myself. Please check before buying!
