@lexd0g apple used to have an app to help people migrate from an Android phone to an iPhone. To use the app, you'd type in a number displayed on the new iPhone into the old Android.

It didn't allow you to use the phone's software keyboard, instead it had a keypad on the screen. The app also assumed the Android device has a 16:9 aspect ratio screen.

A family member's phone had a 3:2 aspect ratio screen, so the keyboard went off the screen. I can't remember if I couldn't click the summit button, or the 0 button, but needless to say the app was useless.

Apple made it so much harder to move a family member to an iPhone. I had to use a 3rd party application. It's incredibly frustrating
