Get the best samsung you can afford. But that phone should easily last another few years. It really depends on what you want out of a phone.
As a power user, I have always had a note, then the S22 ultra.
When I didn't use my phone much, I always went with the best A series I could afford.
You can check all the specs on the GSM arena's app or site and compare up to 3 phones.
You can try other brands, of course, and get more features. I just prefer samsung products as they just work and have great phones.
If you're finding it's getting sluggish and slow, you could clean up and use the members app to check all the diagnostics, too, which checks everything on your phone.
If Your happy with it for what you need it's always tempting to justify buying a new one, but I at least wait till I've got all the updates and patches possible before I get a new one. Then I have a reason, too.
