I upgraded my phone to a 5G model, using Phoenix wallet, all i had to do was make sure the app on the old phone was deleted, and then import the 12 seed words into the new one. Then the channels came back, the balance, and also the LNURL login functionalities. I mean the websites i had created logins with on the old phone, worked on the new one. It was so easy. Things like that, is kinda cool imo.
