This isn't a G4 pic, but it's something that I think you guys will definitely love.
Know the Galaxy S6? My favorite feature about its camera is that home button shortcut, where pressing it twice quickly will quickly launch the camera app. The G4 has that too, albeit only in the lockscreen since it relies on the volume keys and trying to do that while the phone is unlocked won't do anything aside from making your music softer.
I remembered using an app called "Home2 Shortcut" to do exactly that on an old S3 instead of it launching S Voice. So, installed it, got around the Gingerbread-era UI and got it to work. It actually works quite well, and launches in exactly the same fashion as on the S6.
There's only one funny glitch. Sometimes, tapping the home button twice will bring up the recent apps screen instead, and to launch the camera, you'll have to press it 3 times if double-pressing it brings up the recent apps screen, which is a little odd but definitely not something that says "My phone broke".
