Well, knowing the general specs for a while there is nothing really exciting as far as features to make the new phone that exciting.
Spec bump here and there but for the most part not anything major different from last years and at the end of the day will basically run the same as the older gen unless your phone is really really old.
I went from S23U to ZF7 with new processor, 200 MP camera and after a few months went back to my S23U and for most part felt the same going to the ZF7 and went back to S23U never said, boy I miss the performance difference of the ZF7.
Leaked videos of the S26U not really showing anything exciting. Might be better off getting better deal getting a S25U for almost nothing than a S26U.
