The first thing you'll notice when you boot up iOS 10 is the fancy new lock screen. It's different looking and you might be a bit shocked to see the familiar "Slide to Unlock" is gone. There are plenty of other tweaks too. Don't worry, most of these changes are for the better.
Regularly locking your phone's screen can be an annoyance. So much so that a third of Android users don't even lock their phones at all, and those that do choose painfully obvious PINs or patterns. Fortunately, there's a better way: It's called Smart Lock for Android.
Windows: Windows 10's lock screen features a cycling rotation of pretty great photography. If you'd like to save the images you find, here's where to find them on your hard drive.
Android (rooted): Some Android handsets support a "knock code" unlock feature -- tapping on the screen in a certain pattern to gain access. An Xposed module can bring the same option to just about any rooted phone running Android 4.2 and above.
