Does Auto brightness actually work???
When I bought my first iPhone (4) I never knew the auto brightness actually works straight away when you walk from a bright area to a darker one, or vice versa. I had an issue with the home button and later my Phone provider swapped a new one for me. This replacement iPhone 4's auto Brightness actually dimmed in lower light areas noticably and in real time. It was really handy and the way it should work.
I recently upgraded to iPhone 4S, and noticed that the auto brightness doesnt change. I checked with my wife's iPhone 4S too and its the same problem.
So, I want to know, does it actually change like the miraculous replacement iPhone 4 I received or is auto brightness a "meh" function that I shouldn't expect it to change. The reason I am asking is because I find in darker rooms, the iPhone is way too bright and I have to keep changing the brightness manually.
Everytime I do this I always see the Auto Brightness funtion on and its starting to bug me that it doesn't work like my old iPhone 4 did. Can someone explain if Auto brightness actually work?
