What is the phenomenon of light leakage in Xiaomi Youth Edition? Are the youth editions all the same?

Yours is fake. You can see from the warranty card that it is old. I also bought the official genuine Xiaomi mobile phone warranty card and accessories that are returned now. Please take a closer look. Every authentic place has the logo of Xiaomi. Some fake MT or no name at all, but the appearance is similar to the system 100+000. The appearance can be done and the system can be brushed. There are also problems when watching it.
