Thank you for viewing. SIM-free docomo SONY XPERIA 1 IV SO-51C Black (K) Includes a new LCD protective glass film. The device body shows signs of wear, such as scratches and case marks on the edges and back. The LCD screen surface is nearly flawless, but there are some unevenness, discoloration, and burn-in. After purchasing and using the device in the market, I have reset it for this listing and checked the following items upon startup. However, I have not used all the functions, and as it is a precision instrument, I cannot guarantee the operation, including the checked areas. There is a possibility of defects, but please understand that it will be delivered in the condition it is in upon arrival. Sold as seen.
