Default [q] just bought lg g2 - camera prob!

Hey guys ,

I just bough an LG G2 today and when i started using it the camera was really good after some app downloads like snapchat and viber i got my camera blurry and laggy .. especially the front one.. But what i noticed is that this happens only when using the Camera app . if i use Instagram camera or F.Messenger it works normal.. Anyone knows whats wrong with the camera app or what its best to do ?

Thanks a lot !!
