"mostly acceptable teardrop everyone else standardized on."?
Yeah, that's pretty delusional. I don't think anyone has created a phone with a notch that would accurately be characterized as a teardrop shape. The closest was probably Essential (which inexplicably had a notch and a chin). The Pixel 3 notch is a V shape. The OnePlus notch pretty much looks like an iPhone notch. There's no "standard" and certainly no "standard teardrop shape".
It is trend among chinese phones (Huawei,Oppo, Vivo, OP ..basically BBK electronics)
OP 6T is the first phone popular in the west with this style, and I find it to be amazing.
Still like the MiMix 3 the most, with no notch. But, the OP 6T is the first one that's not egregious.
