S25 and S26 have faster camera, but much worse quality than the old S9, too noisy image and blurry (they probably wanted less depth of field) :-(
Also much worse sound quality from the speakers :-(
Cameras have been the same for several years :-(
Local AI only in a few languages.
All this for 2x the S9 price.
The camera zoom in OneUI is also not good. It does not allow you to zoom with one lens only, it constantly switches between them and because the cameras are not in one place physically, the image moves when zooming and you lose the frame and focus. It is also not possible to use zoom in selfie mode at all. When taking a photo, the LED always turns off, so you can't take a photo in a dark room - you simply can't use it as a light. Too bad. Chinese phones are better.
Samsung is declining.
