I've been with him for a few days now and I notice a big change from Fold 6, especially in terms of form factor.
It's very, very light and thin, almost as much as the iPhone or Pixel. Deployed is so fine that it even makes something to walk with him, it looks like he will fly.
The larger screen, both outside and inside, is also an appreciable improvement. The exterior is now like a normal phone, and the keyboard is quite wider, which makes you type more comfortable than the previous model. It's something I noticed instantly.
Unfolded it is noted that it has a top diagonal, but the most remarkable thing is the fold, barely noticeable to sight or touch. I liked the camera under the screen, as it gave a more "homogeneous" and "futuristic" look, but the quality of the interior camera is noticeably superior, although it is not used much, it is appreciated that it has minimal quality.
The 200 MP camera is a substantial improvement over the Fold 6, although I think it is not enough to surpass the iPhone or Pixel, if it is now up to these. A shame the 3X zoom, with the 200MP sensor almost makes it unusable, because sometimes it is better to "crop" the 200 MP photo than to use the zoom. The bulk of the camera is exaggerated and makes you dance without a cover. I have ordered the transparent with the magnetic ring to use the chargers I have for the iPhone.
The battery is currently slightly lower, although it is true that I am using it more.
The audio confirmed that, without being bad, it is worse than the 6.
The fingerprint sensor works well.
Overall, the change is quite noticeable, it seems that more than a generation has passed.
