I've previously selected a manual mobile network through
Settings > Mobile Networks > Network Operators
Now I want to set it back to automatic network selection, but I can't see where. Researching online it seems it should be the top button on the Network Operators page, above the button to start the search again, but it's not there for me. I work at sea so go in and out of roaming and my home network areas several times a day.
Z3. I'm now on Marshmallow though it was the same in Lollipop too.
Any help appreciated!
