With over a decade under its belt, Android has built a long history as Google's mobile operating system. And in that history are dozens of little features, changes, and updates that have added, removed, or modified aspects of that OS in subtle and not-so-subtle ways. But for every new option Google brings to Android, we're probably forgetting one that been in there for years that we've simply not bothered to use in a while. And in some cases, these are pretty genuinely useful things!
Remember you can use two fingers to swipe down for quick settings? Screen pinning? Lock screen messages?
The developer preview of Android N may have been released a week ago, but we're still discovering loads of changes and new stuff across the OS. The most recent one that's come to our attention is a new toggle in Sound Settings for mono audio, which makes both left and right audio channels get played back simultaneously through any active sound output.
There are plenty of reasons why someone would want to play sound in mono instead of stereo. Many people prefer listening to music with a single earbud in their ear, but with stereo playback this meant that half the song was never heard.
