Coming from an iPhone 11. Can’t use OLED screens as they give me headaches and eyestrain.

My iPhone 11 is really beat up and slow. Just want a snappy phone for use when I am out and about. At home I am mostly on my iPad/Mac.

How much smaller are the text on the SE? Which app is the most difficult to adjust to on the 4.7" screen? Is it video based apps like YouTube/Netflix, or something else? Do you ever find yourself squinting at the small screen trying to read or decipher something?
