My wife refused to upgrade her S10+ phone, she thought it was the cats meow, since getting the S25+ it thrilled her after she learned how to operate it. Thank you.
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.
