mmark271 is correct according to samsung website lollipop is schelduled to be pushed tomorrow
You were absolutely correct! I received the update at 1am this morning. My phone does respond faster and my data connections improved after the update. I will test the voice calls later on. The update wiped out a few things. It took a while to get some of my apps from Amazon reinstalled and so far, they took away the Call Block function from the settings menu. I used that feature daily and now its gone. There isn't a Do Not Disturb function either. I hope the next update will replace it. Going to the top does make a difference. Thank you!
