Notches are flaws and a step backward for mobile phones trying to fill in the "look I am different" spot. The first is this example, you can see notches suck. If you use the feature to hide the notch on the Apple iPhone you lose another portion of useable screen space. Even the Samsung S10 micro notch is intrusive. How about the Oneplus? Please! No more notches!
Fortunately, manufacturers are noticing this flaw and coming up with some elegant looking screens such as this render from Lenovo.
It is my strong opinion that notches are a flawed design that delivers only one value. The frontsixe camera. I certainly don't use more than once a year. The value as it effects the viewing experience is negative in my humble opinion. Aren't notches something you whittle into wood or into your belt? You don't put them on phone screens, please! No more notches!
