#FOMO. If it bugs the living hell out of you that you don't know what that means, you're presently FOMO, as in you've got a Fear of Missing Out.
In the world of mobile devices and everyday gadgetry, FOMO is ubiquitous, which means that GS3 you have is looking pretty lame when there's a GS4 out there. And it's usually the little things that make you want to upgrade, like small additions to the lock screen.
The lock screen on the Samsung Galaxy S4 (and Galaxy Note 3) has more customization options, like the light feature in addition to the ripple effect, and editable text up top. But you don't need to upgrade to a GS4 to get them—just upgrade your trusty old GS3's lock screen.
All you need to do is download the Galaxy S4 Lockscreen from Google Play and enable it in the Settings menu.
UPDATE: This app is no longer listed in the Google Play Store. If we find an APK of it, we'll add it to this guide. Otherwise, you will not be able to download it.
Once installed onto your phone, you can tap the app icon to access the Settings area.
Here, you can change the Lockscreen Effects and personalize a whole host of other features.
My favorite thing about GS4 Lockscreen is the new swipe effects. I was getting pretty tired of the standard ripple effect. Now, you can add different colors to that ripple, or change it up with completely different ones like blood or blue rings for the light effect.
You also change the text at the top. I love my phone and everything, but "Life Companion" is a stretch.
Now that's more like it.
Overall the app is almost too easy to use, but there are ads when you access the app itself, and users have voiced security concerns since it works best without a lock screen security option enabled.
