i mean, your S23U already support 200 MP of camera, the only good about S25U camera is 50MP ultrawide camera, do you need it?
S25U can't charge s pen, even if you buy s pen with bluetooth separately you can't charge it, so if you use your s pen bluetooth then stick with your S23U
also S23U still going strong up to 2027 because S23U will be supported until Android 17, and S23U already a really beast Snap 8 Gen 2, you don't need to upgrade tbh
all S25U Galaxy AI feature will be available to your S23U once your S23U updated to One UI 7
i almost forget, you will lost 10x optical zoom from S23U periscope camera because S25U can only do 5x optical zoom from its periscope camera
