                  My sim is 5g enabled (I've tested it in my iPhone 12 pro) but it doesn't show 5g on my s21 5g, even though there's a 5g option in the settings

                    A lot better after Android 15 upgrade, often old software can corrupt and slow down your phone, even on iPhone. Great to access the new AI features without upgrading to something new. Also, there was a black screen issue and it seems to have been a software bug, fixed with the update. It's great, I'll keep this phone for a lot longer.

I can tell you that S21 is better than S22. Better photography, better performance, better display and of course better battery. Now I will sell S22 and keep only S23 and S21. S23 slightly better than S21.
