You can make several changes while reading to make your screen easier on your eyes.
- Tap the centre of the page to bring up the Reading Menu.
- Tap the Brightness icon.
- Tap the reading theme you want to use. If you're reading at night, the Night theme is specially designed to make it easier to read by displaying white letters on a black background.
- Under Brightness, drag the slider to adjust your screen's brightness level. If you don't see a brightness slider, you may need to enter your Android device's Display settings, and disable Adaptive Brightness.
- To save your settings and resume reading, tap X.
