Did you know that your iOS 8 Apple iDevice has a built-in Night Mode? You probably don't, or at least we didn't. By far, this is the most obscure iOS feature we've ever experienced, and we've been through our jailbreaking/Cydia days, thank you. It's buried so deep inside the system menus that simply stumbling upon it by yourself is a very unlikely event. Thank Reddit user marksalnikov
for enlightening us on how to dim the iPhone/iPad/iPod Touch's screens
for comfortable night-time use. The instructions worked, so we're passing along the good stuff.
Mind you, there's no jailbreaking or app installing of any kind - just good old-fashioned lurking in the menus!
