Yeah but under sunlight screen is barely visible except only when you set it to 100 % brightness and you know that.You really don't want to go above 50% and certainly not to 100% for frequent or prolong times. AMOLED displays have a finite lifespan and what burns the brightest, burns the shortest.
Using it like that in direct sunlight is especially damaging, you can fry display drivers like that especially in high ambient temperatures. The active matrix screen has 10's of thousands microscopic solid state junctions not including the OLEDs... and very little heat sinking capacity.
The OLEDs and their driver matrix generate heat, the brighter it is, the higher the current draw and heat output.
Much of the heat sinking is through the display glass its self. Glass is a fairly good insulator, worse the sun's IR energy goes in and is trapped by the glass ie greenhouse effect.
It can go over temperature very rapidly before the device can thermal shutdown to protect its self especially if the device is already running hot or charging.
So adaptive brightness is set ON,but anyway I need to increase the brightness outdoors maybe not 100 % but 90 % but what it makes the difference then?
