What’s there to argue about? It is a patent of vivo itself. Xiaomi's one pops out and is easily damaged. Vivo's one uses another principle. There is a motor to drive the camera to expand and retract. There is no comparison. If there is really a competition between good and bad, then of course the vivo one is better! Xiaomi's is a manual one, which causes a lot of wear and tear on the phone. . .
