I'm so pissed I made an account to post this.
I need to buy a new phone and EVERY phone with half decent specs is 6.5" or bigger. Who needs this stuff? I remember when 5.5" was still too big. these older phones had, at least, a nice square screen, light sensors and proximity sensors and looked fine. then apple launched iPhone X and everyone started to want the stupid notch, culminating in today's stupid trend of having notches and punch holes as a fashion statement. Nobody was ever hassled by 1-2 mm of bezels on the sides and 3-4 mm of bezels on the top and bottom. Notches are absolutely stupid and need to die, but instead we have idiots thinking they are good and fight over which looks better. the correct answer, is 'none'. Except perhaps the ones like iPhone X, at least these are tolerable.
My theory is that notched displays were engineered to be cheaper and cheaper and once the cost difference between a notched screen and a normal one became less than the cost of all the light sensors, proximity sensors, dual cameras and LED flashes, they made the switch, since you have no space for any of these in a notched display.
