How to evaluate Meizu copying Xiaomi suspended ball sliding operation interaction

The m9 released by Meizu in 2009 copied the appearance of Mi 1 1, and then copied it in advance, including the floating ball function released by 12, which copied the function just launched by Xiaomi in advance. Meizu has already copied Xiaomi in advance! Including the idea of developing mobile phones in 2007 is to copy Xiaomi 1 1 year in advance! Have time to check the personal enmity between Lei Jun and Huang Zhang. Don't be a brainwashed rice noodle!
