Apple will purportedly completely drop the use of a notch in its iPhones by 2023 according to display expert Ross Young. Young, who has a very good track record in regard to Apple-related leaks and news, states that the dual hole-punch design expected for the iPhone 14 Pro models will be used across the board for the Apple iPhone 15 series.

Things improve in decreasing order: notch < two holes < one hole / drop. Regardless, I do not buy any such device.
