Whenever im scrolling through fb etc the screen is lagging or when when im closing an app its not as smooth as it should be. Motion smoothness is on adaptive so im not aure what else to do. Im also constantly getting no Internet connection when on fb, Google etc. For what this phones costs u expect decent quality, this galaxy has been the worst ive had so far definitely thinking of going to iPhone next time which is surprising as ive had the galaxy range since it came out
