Hi all, my p30 pro, when the screen is woken up in the bright sun, it goes to max brightness. However after about 30 seconds the screen dials back the brightness to about 75%, and even if it manually move it back to 100%, the screen doesn't get any brighter. I have tried all the setting regarding the display, manual, auto, vivid etc. I have factory reset the phone as well. Any thoughts or ideas please?
