Install Nougat if You Use Your Galaxy Note 5 at Night
If you tend to stare at your Galaxy Note 5's screen at night you might want to install the Galaxy Note 5 Nougat update.
The Samsung Galaxy Note 5 comes equipped with a new blue light filter that warms up the Galaxy Note 5's screen at night.
The feature is similar to f.lux and the Night Shift feature Apple includes in iOS for the iPhone and iPad. Google's also released a similar feature for the Pixel XL and Pixel smartphones.
This change could help you get a better night's sleep by reducing eye strain you'd typically incur when viewing the display's normal colors.
You can adjust the tone of the screen to your liking and you can also schedule the phone to use the filter so that you don't have to do it yourself before bed.
