Honor Luowei: The Honor 400 lens uses the best high-strength glass, so there is no need to apply a film.

On the evening of June 14, Honor's Chief Image Engineer Luo Wei posted on Weibo, suggesting that users of the Honor 400 series phones should not attach lens film. He said, "Not attaching lens film affects the photo quality and can also cause interference. Now our lenses are made of the best high-strength glass, so there is no need to attach film on the lens."
