I have a non-rooted LG G2 (LS980) and I love the quality of pics from the stock camera except for slow shutter speed. Anyone have any good recommendations for a 3rd party app that maintains the great quality of photos but has a faster shutter that they use? I'm not interested camera apps like cartoon camera or other apps that add crazy effects. Just want an app that takes regular pictures in high quality consistently and quickly.

Ready....go....
[thanks in advance]
