Answer: After researching for a long time, I finally found the reason. It turns out that for the first setup, you need to first turn off the automatic brightness adjustment switch, then go to an absolutely dark place, cover the light sensor with your finger (to block the screen light), and then adjust the brightness slider to the darkest.

At this time, turn on the automatic brightness adjustment switch, lock the screen, unlock, and the function will return to normal.

If you put your phone under a desk lamp during setup, turn the slider to the brightest, and then turn on the automatic brightness switch, then it becomes very sensitive to bright environments, and the screen will dim quickly.

Quick Knowledge: Later, I learned that after ios6 optimizes the system, the automatic brightness adjustment needs to be calibrated by itself.
