This is a SIM-free model. The battery was once replaced at an unofficial repair shop, but it seems a low-quality one was used, as it didn't last long, and the shop closed soon after. There are significant scratches on both the top and bottom. This is a ONE UI 7 compatible device. Animations are smooth. It has a maximum 120Hz display, which is vibrant and beautiful. Would this be suitable as a sub-device? The color is pink.
