Hi guys! Got my Note 4 last week and so in love with it! So far I am just obsessed with the camera - such clear picture! However, a lot has changed it seems... is there a guide or something that outlines ALL the features of Note 4 (even those added and kept from Note 3)? S-Pen also seems to be so much better.... but again, I don't know the full extent on what I can do with it. I am also noticing that some apps seem to be laggy and crash. Is this because those apps are not supporting this android version yet? And some just act weird. Yesterday I uploaded a video to instagram that I took with the phone's video camera and instagram truncated the bottom part of video. Anyone knows anything about this? thanks guys!
