I'm still finding my way around my new Samsung Galaxy S Plus.
I've noticed that, when I make a call, the screen goes blank as soon as the call is connected. When I want to end the call, I can't work out how to get the screen to light up again so that I can press the "End Call" button. I've tried lots of suggestions, sometimes the screen flashes up for a split second, but not long enough to let me press the "End Call" button.
Is it supposed to do this and what is the proper way to end calls please?
