It has been acknowledged that 6a FPS was never the best when compared to most of it's competitors. That being said, I have no major issues with it on my unit.What I noted for 6a so far. Haha the fingerprint sensor really not good. Dunno why after recent security update seems to get worst. Alot of times ended up using pin.
Gaming wise, played immortal.. suddenly the whole phone went crazy keyboard type all the gibberish.
