    I have recently realised that the autobrightness is no longer working automatically under low light. Whenever im constantly using my phone in the night; and were my lights are turn on, after turning the lights off(complete darkness), my iphone doesn't dim the screen!

    However when doing this transition viceversa; from low light to high light; the iphone does increase the light the screen for it to be more visible.

    I also found that when im using my phone under low light, and the screen is too high that it causas fatigue, the only way -besides manualluly decreasing the brightness- is to lock and unlock the phone. When unlocking the phone, the screen keeps dim. Now, when turning the lights the screen does increase its brightness.

    So in summary:
    - low light -> high light = the screen brightness increases.
    - high light -> low light = the screen WON'T get dimmer/decrease brightness!

    Anyone else experience this issue thus know how to solve it?

    Thx in advance
