I can't speak for that device in particular, but I've been using a Galaxy Fold for a few years now and the crease is literally nothing. In most cases, you're looking dead on at the phone and you can't see it. If you're outside it becomes slightly more noticeable, but the bright glare from the sun in general makes for more of a problem than the crease. I have no intention of going back to a non-folding device.

Also, Huawei is not banned from being purchased and used by consumers in the US lmao.
