Hello Jhc2022,
Welcome to Apple Support Communities!
We see you viewed the Apple Support page to Move from Android to iPhone, iPad, or iPod touch - Apple Support
Have you already tried the steps from this section in the Apple Support article?
"If you need help with the transfer
- Make sure that you leave both devices alone until the transfer finishes. For example, on your Android device, the Move to iOS app should stay onscreen the whole time. If you use another app or get a phone call on your Android before the transfer finishes, your content won't transfer.
- On your Android device, turn off apps or settings that might affect your Wi-Fi connection, like the Sprint Connections Optimizer or the Smart Network Switch. Then find Wi-Fi in Settings, touch and hold each known network, and forget the network. Then try the transfer again.
- Restart both of your devices and try again.
- On your Android device, turn off your cellular data connection. Then try the transfer again."
If the issue remains, do you have all pending updates installed on both devices? Are you able to test with another Wi-Fi network?
We hope this helps isolate and resolve the issue so you can transfer the data to your the new iPhone.
Cheers!
