Night Mode is a powerful screen filter that makes the colors of your device’s screen look warmer, and reduces the amount of blue light that reaches your eyes, which can prevent you from feeling tired and having a poor night’s sleep.

This screen filter can be activated from the settings menu on your device. You can also activate it from the Night Mode Enabler application.

In order to activate Night Mode, you will need to install the Night Mode Enabler application. You will be guided through the steps to activate the screen filter.
