You need to add several apps from Good Lock. Camera Assistant to get that 2x zoom and other feature. Sound Assistant. Keys Cafe to customize the samsung keyboard. And One Handed+ for more convenience.I installed good lock and themepark but haven't delved into it. I was trying to get my icons straight. The issue I have is that on BLACKBERRY (shoutout to @TimRock), when I installed an icon pack, even if there wasn't a certain icon, it would modify them so they all had the same effect to blend in. I use a glass icon pack, same one as i had on my key 2, if it's not in the pack, it puts it in a circle shape, but doesn't have the glass effect.
