If you feel good about your phone, stay with it, we are in the same situation, I have a S20Ultra and I am not thinking of buying another device at the moment because today it is completely new, not even a whit on the screen, cameras and on the back. Totally new and since Samsung chose to remove the SD Cards (Memory Cards). I was left with the S20Ultra and I have nothing to envy, the Moon looks the same as with the S23Ultra, I don’t know when they will change the design or do something better, I decide later to get another device although I didn’t get to Android 14 either, I don’t care, right now I have an S23 and practically the same, that if the sides changed it looks like an iPhone 😅😅 sooo I don’t see much Innovation.
Galaxy S23Ultra or wait for a Galaxy S24Ultra in 2024.
