偶然发现自己s21u比朋友p40p的最高屏幕亮度低，突然害怕是上次换屏的后遗症，马上google了一下，发现了手机屏幕亮度的小知识：自动调节的最高亮度会远远高于手动调节能达到的亮度。可以通过先手动调到最高亮度后用闪光灯照射的方法实践出，结果是屏幕会变得更亮。
如图可见苹果是最高自动亮度和手动调节一致，大多数安卓手机限制了手动能调节的最高亮度。
The S21 Ultra’s brightness is beyond any other OLED display on the market right now. Manual brightness is still limited by Samsung to only 462 nits, however when in auto-brightness, it goes to a staggering 942 nits – almost beating the superbly bright RGBW LCD display of the LG G7.
（The S21 Ultra’s new panel uses a new hybrid oxide pack panel technology along with a new OLED emitter generation that allows it offer seamless fine-grained refresh rate switching along with getting extremely bright while being much more power efficient. ）
