Hello, I have installed 3CX on a LG G3. It works fine, but I don't find how to quit the application. As there is no menu button (hard button) on this phone, the solution described in this post (http://www.3cx.com/forums/how-do-i-quit-3cx-android-40244.html) cannot be applied. How can I quit 3CX without killing the process ? Thanks in advance for your help.
