Set Animated GIFs as your Android Lockscreen
If you want a change from the default still image lockscreen on Android, then this is the perfect app for you. This free app gives you a huge amount of GIFs to choose from, which you browse through by shaking the device. Once you find one that you like, you pin it to your lockscreen, and you’ll see it each time you turn the screen on.
Just about every GIF runs smoothly, however the only way to navigate them because each time you shake the device, it selects a random one. I’ve had the same GIF go past 8 or 9 times, and I’m yet to come across the ones advertised on Google Play.
