Had a Huawei Mate 3 , honestly best phone I ever had, great battery life, amazing camera and fast. Too bad they got embargoed by Google. Would still use it today if I hadn't smashed the screen. On a OnePlus now but camera and battery life not the same.

Mate lite have shity camera...

You cannot, GrapheneOS is Pixel only.

Ah, ok... 😏
