Fix an iPhone Screen That Suddenly Became Dim
The instructions below are going to assume that your iPhone is running iOS 7.

You can read this article if you are running a version lower than iOS 7. That article deals with lowering screen brightness, but you can easily adjust it to learn how to make your screen brighter. Step 1: Swipe up from the bottom of the screen. This is going to reveal a menu that looks like the image below.
Step 2: Move the brightness slider gradually to the right until you reach your desired level of brightness. Note that the brightness level will adjust as you move the slider, allowing you to get an instant response to the adjustment.
