How to lock phone without ending call
I Can press my lock ton while I'm on a call and it won't hang up the call. But my friend is having is problem and I don't understand how to solve it. I know once my other owns and i figured it out, but I can't remember.
I Know there's a way where you can physically press the button and lock it and keep the call
i don't want nothing about proximity sensors and how it can lock on its own. I want to know why my phone can and his can't and how can he solve this
