Default Photo Editing App Missing LG G Pro 2

So there was this super cool free Photo Editing Application in LG G Pro 2 (LG D383) since the time I bought it. The name of the app is Photos I guess. And now I can't find it anywhere.
Whenever I long press on an image now and hit the Edit option an error pops up saying "Connection Error."
This app came with the phone itself. It even had a "Before/After" Comparision option always visible at the top rigth corner of the screen.
CAN YOU GUYS PLEASE HELP ME WITH THE NAME OF THE APP. I can't find it on Play Store and please let me know how to retreive it.
(It had filters like Drama 1, Drama 2, Cool, Warm, etc)
