Apple

I have been using an Android Razer Phone 2 for several years. I decided to upgrade to an iPhone 15 Pro Max today because my old phone just doesn't work anymore. It hasn't had updates or support in a very long time, and most apps won't work on it.

The guy at AT&T assured me it was easy to transfer my data. He proceeds to download the "move to ios" app and it gave an error message (as the razer phone usually does.) So now I'm at home with my new phone but don't know how to transfer all my pictures, videos, contacts, etc.

If anyone could help me I would greatly appreciate it.
