If you have friends who own a Google Pixel or an iPhone, you might've heard them talk about a feature that helps them sleep at night. (On iOS, it called Night Shift Mode). The Samsung Galaxy S7 Nougat update delivers something similar.
If you use your phone at night, you might want to install the Nougat update on your Samsung Galaxy S7 or Samsung Galaxy S7 Edge. The update delivers a new Blue light filter mode that will reduce eye strain when viewing at night.
When this mode is active, the device's display will automatically start using a warmer colors at night. This could help you get a better night's sleep.
You can control the tone of the screen (maybe it's too warm for your liking) and you can set a schedule so it turns on every night before you get into bed to read the news or talk to friends.
