Hi, i own the A40 for a few months now. And since a few weeks i noticed the automatic brightness function does not work like it should.
A lot of the time the brightness is way to low and when im outside i cant see the screen in bright sunlight. I need to figure out where the toggle button is to turn of the auto brightness and move de slider to more brightness.
A little frustrating.
Also it changes very slow when light conditions change. Sometimes it does not change brightness at all.
I also dont see any light sensor on the phone.
I never had this issue with my galaxy A3 2017. I wish i had never sold that phone and never bought this. It is in no way better that the A3 (for me anyway) and the size of the A3 also was way beter.
I came acros this thread about the S10 on XDA: https://forum.xda-developers.com/galaxy-s10/help/auto-brightness-guys-t3909444/page2
I followed the instruction to do this: Additionally, developers say that users can reset the brightness curve to start the learning process again. To do this, go to Settings – Apps – Show system apps – Device Health Service – Storage – Manage Storage – reset Adaptive Brightness.
ill try it out and post my findings.
