New to One X2, can not connect to Samsung Android

Pretty sad, I can't even work out this forum?

So, I have a One X2 and have tried for 3 days to get it to connect to my Samsung A20. I have downloaded the app, I have watched a dozen tutorials and read pages of 'how to' on doing it... however, my phone comes up with my camera but says 'can't connect' in the app. It gives me the name of the camera and the password in the app and says to go to the phone settings... however, even tho the phone shows the camera, there is nowhere to put the password.

On the phone, it says something like 'an app is needed to run this device' When I get told in the app the name and password, it says to go to settings and add the name and password... I have typed in the name 100 times, but there is nowhere to put the password?

I am at a loss. On the tutorials, it says to turn on the phone, click the camera app and select the camera and once connected, enjoy your camera... However, in reality, clicking on the camera icon just starts the merry go round of not being able to connect?

Hopefully someone here will be able to help?
