Hi! Since my Note 4's Lollipop update last week, I am very frustrated with what the dialer does during outgoing calls (not using HD calling right now). After I make the call, the call screen disappears into the notification bar and I have to swipe down (being careful not to touch the sensors that make the screen go black) to get the dialer back on the screen. This is really a pain when I need the keypad. I really just want the dial screen to stay on the screen full size. I can't seem to figure out how to do this after much Googling (maybe because people don't think it's a problem...but it's a very annoying problem for me!). Any ideas on how to fix this? Many thanks! Amanda PS...Incoming calls are fine...dial screen stays full size on the screen.
