Switching from android to iphone 6

My partner is wanting to change from his Android phone to an iPhone 6. I’ve done the research and I believe going through the Android app 'Move to iOS' Is the easiest way. I reset the iPhone before starting anything. I set up it all up and the app was working OK. I was expecting a display on the iPhone similar to the Android phone but I didn’t realise one of my Apple devices had picked up a ‘signal’ and tried to set up the iPhone linked to my iPad and iPhone. I got so far through the setup before I realised my stupid mistake.

So now when I start to go through the motions of setting up the iPhone from the Android one, the iPhone still goes to the page to set up the iPhone with one of my other devices. I have tried restarting the iPhone 6 several times and it still comes up with the same screen. I have also tried switching off all my devices and even gone into another room but I seem to be going round in circles. I hope someone comes up with a solution to this problem - it’s driving me mad! Thank you!
