One of the advantages of owning an iPhone is its ability to adjust the screen intensity depending on the current environment. Unfortunately, this auto-brightness feature has been known to be a little bit clunky at times, especially on the iPhone 5.

If your auto-brightness isn’t working on your handset, here is how to fix it, courtesy of iMore.

  1. Go into a dimly lit or dark room.
  2. Launch the Settings app from the Home screen of your iPhone/iPod touch or iPad
  3. Tap on Brightness & Wallpaper.
  4. Turn the auto-brightness setting to Off.
  5. Adjust the brightness slider to the level you would like your screen brightness to be at in the given environment. For instance, if you’re in a completely dark room, you’ll probably want to put the slider all the way to low or pretty close to all the way down.
  6. Turn the auto-brightness setting to On again.
  7. Now flip on a light switch.
  8. Watch the brightness slider move upwards to adjust to the new light entering the sensor.

Here is the video:

Assuming that the brightness slider is now moving on its own, you have successfully re-calibrated the feature. We thank iMore for posting this information.
