First time user of a Samsung phone. Had the s-view cover on from day one and the auto brightness adjust worked great didn't even notice it switching between lighting. Just recently I changed to a normal cover and noticed with my auto brightness ticked I get a 3-5 second lag on waking the phone.. It will be really dark and I have to wait before the screen adjusts and I can use it. Is this common in these phones? Did the S-View cover really make a difference? I'm curious to know, even though its only a minor issue its still of annoyance. Thanks guys!
