I hear this all the time and think ...
I've never faffed around getting menus, apps or anything to work in the various android devices I've had over time .. can't help to think what it is about android that some folks don't get.
Mine have always 'just worked'.
OTOH .. trying to get my sisters iPhone to connect to her security camera system .. setting IP addresses and specific port requirements .. and zip! .. nothing nada .. just wouldn't work no matter how many hours I faffed around in the settings.
My phone connected straight up found the connection and port and cameras all online. Problem was that I had no need to connect remotely to her security cameras.
