I was looking at some new phones recently and phones made in Asia (Xiaomi, Huawei, Samsung) seem to have the same design to me. They all seem to have lots of padding on UI elements, seem to use the same fonts, and seem to resemble a shared design language. They seem to look different from something like stock Android or a Pixel. Is there a reason for this, or am I just crazy?

Edit: The settings app seems almost the same in those phones (I think), for example.
