Hi, there are so many apps out there and I'm not sure if they're safe for transferring info, like contacts, and personal messages. I'm trying to transfer info from my LG phone that seems to be dying to an iphone a couple of years old I just got (it's an iphone 10), and trying to figure out the safest and most secure way. Appreciate suggestions.
