Easily Adjust the Brightness of your Flashlight on the iPhone

Did you know you could adjust the brightness of the Flashlight on your iPhone? Just open your Notification Center and 3D Touch (press and hold firmly down) on the Flashlight icon. For iPhones which do not have 3D Touch, you can tap-and-hold on the Flashlight icon. Once you do this, you’ll see a slider. Just drag that slider up and down to adjust the brightness.
