How to reset the auto brightness function on your iPhone 5 from the new custom ranges

How to reset the auto brightness function on your iPhone 5 from the new custom ranges
With iOS 6 the auto brightness function received an overhaul, and started working in the lock screen now, too, so the display doesn't burn your retinas when you wake up in a darker room, and grab your phone with brightness settings memorized on high. 

It is also now meant to adjust quickly from dark to bright environment, but gradually if you go from a lot of light to dimmer places, just like the human eye does.

However, this gradual adjustment, along with the "range brightness" used in the iPhone 5, which memorizes the position you manually put the slider in for different ambient light scenarios, and works its way up and down in a limited range from there if the auto brightness is on, make it look like nothing gets adjusted, even when you lock/unlock the phone. 

To reset the automatic brightness to its usual regime, and snap out of that range memory thingy a lot of phone makers are now using with varying degrees of success, especially for the extreme situations, you need to reset the iPhone 5 for the lowest brightness setting: 

1. With the auto brightness switch OFF in settings, and the brightness slider at minimum, take the phone in a darker environment, like the bathroom with lights off, or a drawer ajar, for example

2. Turn the autobrightness switch to ON, and turn the lights on, or open the drawer fully, and you should see the slider move up on its own with a nice animation, going even further up when you venture outside, then bring itself back when you reenter, but more gradually than what we were used to before

It is a new way of working the automatic brightness, especially useful with the lockscreen dimming now, but if you set it at maximum manually outside, then turn the auto switch on, nothing will get dimmed down when you return inside, and vice versa, so people report doing the above reset, then just leaving the switch ON at all times and not touching the slider to avoid those "range" hassles.

For a visual explanation of the new customizable brightness settings, have a look at the fan made video below, starting at 0:35 into the footage.

Are iphone users really so dumb, that you have to take lessons on display brightness... How dim do you have too be? Question, how many iphone users does it take, to change a light bulb?

It's not about them being dumb or not. I'm leaning towards they are. It's about iOS being complicated. This whole thing about iOS is easier to use is Apple marketing, and it the farthest thing from the truth. They even have "geniuses" to help people. How many other "how to's" have you seen from PA on other OS's? I mean iOS is cool if you like taking extra steps. You're going to have to wait for Apple to copy from others and act like they invented it for your iPhone 6 to half the things my Android phone can do now. Like they say one small step for Android one giant leap for iOS. Don't get me wrong though the iPhone 5 would have been cool, like back in 2010.

Comparing iOS to android, iOS is definetly the more underwhelming of the two.

How much of a mindless fanboy do you have to be to click on an Apple article and make such an incredibly pointless comment?
