How to Fix the Brightness on an Amazon Kindleby Lynn Burbeck
Adjusting the brightness of your Amazon Kindle screen can make a big difference in your ability to view the screen comfortably, particularly if you're using your device in a low-light area. Fixing the brightness of your screen is easy on the Kindle Fire, Kindle Fire HD and Kindle Paperwhite, all of which provide screen brightness controls. This feature is not available on the original Kindle, however, as the screen is not backlit.
Tap the "Quick Settings" icon in the upper right corner of your Kindle screen. The icon looks like a gear.
Select "Brightness" from the Settings menu. If you don't see it immediately, tap the "More" icon to access all of your settings options.
Use your finger to toggle the slider from left to right to increase or decrease the brightness of your screen.
Kindle Fire HD and HDX
Slide your finger downwards from the top of the screen to display the Quick Settings menu.
Select "Brightness" from the Settings menu.
Toggle the slider to the left or the right to fix the screen brightness.
Select the lightbulb icon on your Kindle screen. This icon is present when you're reading a book.
Move the vertical slider with your finger to achieve the ideal screen brightness.
Tap and hold the "+" sign to achieve maximum brightness. To achieve the lowest brightness possible, tap and hold the "-" sign.
