I don't think there is much between them to be honest..Al I woukd say is the s23 will have that extra year of updates! From what I've read 📚 it does have a better camera..s22 is still an awesome phone but I'm a sucker for new tech lol but also the fact it will still get updates...
I don't have the S22. But have got S23 and it's a good phone . I've using it since December and have no plans on upgrading over the next 2 years. Samsung is still selling the S23 around £699. Worth a look if not S23 Fe is a decent option https://www.samsung.com/uk/smartphones/galaxy-s23/
The main weakness of the S22 is battery life - it is much improved on the S23, so that's the main reason I'd pick the S23 over the S22. Other than that, the S22 is an awesome device - mine has been my trusty sidekick for over 2 years now and it's working perfectly!
