I have a S21 Ultra and I do not see a reason yet to upgrade. I have the Galaxy Pro 360 that comes with a pen that I never use. If I saw a good reason to upgrade I might have committed to another $1300 payment plan.
the s21 has better resolution? i would have thought the s23 would have made more gains. 2.9 to 3.2 not much difference in clock speed either. 200 camera thats the really only difference
