Who copied the home button of Meizu and Nubia?

Just a small circle. What's the sense of design? What matters is the function of the home button. Meizu's home button is unique, and all the inspiration comes from Apple. These changes can only be said to be reference. If the patent originated in Nubia, it was useless before, because Meizu was gradually becoming famous in the mobile phone industry. As one of the symbols of Meizu, its selling point is definitely there, and it can also increase the exposure. Generally speaking, it is good for both brands. Now this vague feeling is the best.
