How do I backup Android phone previous to picking up iPhone
I am switching my mom's phone (Galaxy S10e) to an iPhone 12. This will be a trade-in so we do not have both phones at home to use the "Move to iOS" app. The guy at AT&T said if we do it in the store it takes a LONG time. So how can we save all her data, apps, texts, passwords, etc to be downloaded to her new iPhone in the future?
