Kindle screen suddenly became very dim on LG tablet running 4.2.2 Can't increase brightness How can I increase brightness of Kindle screen on my LG tablet running 4.2.2? Screen suddenly became very dim. Thanks.
Here's a much easier solution,  especially if the screen is so dim that you can't read any of the display options. Simply place TWO fingers on the screen and slide them up for brighter, down for dimmer. Simple!
