Upgrade was easy but did require two devices. I was NOT able to setup the phone and verify the Google account using the required 2-Factor authentication, it required using another phone or PC that could receive the verification code. It wasn’t until after that, that I was able to use the phone functionality. Not sure how one would set this phone up if you did not have another means of receiving the Google 2-Factor auth code.
The phone lost some functionality compared to the S24, but has other features that may be of some use.
Overall the OS is relatively easy to use and customizable as one would expect.
Easy to order and activate. Went to store and agent created order via app. Got phone very quickly and easy to activate and transfer items from old phone. Exchange of old phone and reception of credit was easy at store and credit qas on bill very quickly on next cycle, so no catch up required.
