1. With my Galaxy Pad, I had to first make it forget my home WiFi password. With the app CLOSED I simply connected to the camera using my normal WiFi connection in the Galaxy Pad. It finally connected and gave me the message that it was connected with no internet. No problem, I wasn't trying to have internet. Then I openned the Ricoh app. and connected there, by AGAIN entering the password. It worked!
2. With my Google Pixel phone, I had to not only make it forget my home WiFi network, but ALSO to disable my wireless data on the phone. Same as the Galaxy Pad, I first turned on WiFi and did a normal connection to the camera. It connected with a message "no internet". Then I openned the Ricoh app and selected the K-70, entered the password again, and tapped connect. It worked!
What a piss-poor job that Ricoh has done with their instructions, not explaining any of this. Only by trial and error I finally got it before I was ready to send the phone back.
Hope this helps someone else who is new like me.
I've answered this several times before on the forum, Selverado, it's not right what you're saying.
The issue is your phone, not the app!
Your Google Pixel is making a decision to not use WiFi.
When it detects that a router that can't get to the Internet (and that's what the camera is, a WiFi hotspot), it's breaking the connection and switching over to your cellular data to get back on the Internet.
So you have to find that function on your particular phone (Samsung used to call it 'Smart Switching' or 'Smart Networks' or something) and disable it, *or* be blunt and just turn off Mobile Data while you're shooting.
