How to Backed Up All My Photos via Google Photos App Only and How to Retrieve All These Photos to My New Iphone's Memory in Easiest Way? [Solved]

So the thing is Google photos is a cloud based service on iOS. You can store only some photos to be offline in the apps settings. So sign in with the same account on your new iPhone and it will take immense data so be sure to be connected to a WiFi network and let the media load… but we hardly doubt if you can store all the media to your phone's hard disk at one go

Also if you look up we think you can download each media through the web version on to your desktop or laptop and transfer them to your phone directly through iTunes.

Just download the Google Photos App again and login with the same google account!

It's simple. Download the same app on the new iPhone and sign in using the same account.

All your photos will appear miraculously.
