The Samsung Galaxy S4 and some other Samsung phones and tablets have a reading mode. This feature is a little puzzling and you might wonder what it is and how to use it. In a nutshell, it simply makes reading easier on the eye.

Samsung reading modeIf you have a Samsung Galaxy S4 for example, reading mode can be turned on by pulling down from the top and swiping across the icons at the top of the screen. Press the Reading mode icon so that it lights up. This is easy enough, but there is more to it than this because it has to be configured.

Reading mode doesn’t work with every app and it has to be set up. Pull down from the top and press the gear icon or go to the all-apps screen and tap Settings. Go to My device and select Display. There is a switch to turn on or turn off reading mode. Turn it on.

Press Reading mode and then press the edit button at the top of the screen. This displays a list of apps on the device and a tick box next to each one enables reading mode to be used with it.

Good apps to tick are obviously Amazon Kindle and Play Books, but you might want to add some others, such as Email, Gmail and anything that has lots of text in. It shouldn’t be used for anything with photos. Tap Done after selecting the apps you want to use.

When reading mode is enabled and you open one of the configured apps, the screen colours are modified and the display has a slight sepia look to it. The white pages of an ebook are therefore not quite as eye-wateringly bright.

Some people prefer this toned down display, but others don’t. You should certainly try it and it works best when reading late in the evening when the light is dim and your eyes are tired.
