Create Nighttime Navigation Mode By Inverting Your Smartphone’s Colors
If you remember what it was like to use a dedicated GPS unit in your car, you probably recall that, at night, it may have utilized a special navigation mode where the maps were drawn with dark colors to reduce glare. It may come as a surprise to learn that most GPS apps for smartphones do not have similar functionality.
However, there is an easy way to create a comparable mode, regardless of what GPS app you’ve chosen to use.
A handy way to recreate nighttime navigation mode for any GPS app is to invert your smartphone’s colors. For an iPhone, you will need to navigate to Settings | General | Accessibility, and then set the Triple-Click option to Invert Colors. Now, when you triple-click the Home button, your screen’s colors will be inverted.
If you’re using an Android device, you will be happy to know that Google’s excellent Maps app has a dedicated night mode. Unfortunately, if you want to use a different app for your GPS needs, Stock Android doesn’t seem to offer an OS-wide way of inverting the system’s colors, although, if you’re incredibly geeky, there are custom ROMs out there that pick up the slack.
