Initlal Impression:
2 words to describe the device: Thin. Light.
I have owned Z Fold 4 before, and sold it off 1 week after owning it as the phone is very heavy and causing my pinkie to hurt when resting the device on it while using the phone. Samsung Z Fold 7 completely addresses my biggest complain!
When folded, it is the same thickness as my Redmi K80 Ultra. When unfolded, it is like 2 50 cent coin thin! Take a look at the hinge size

so tiny compared to the last gen. In case anyone is wondering if the hinge is as good as before as the Z Fold series hinge is known to be able to open and close at extreme angle before snapping to a fully folded/unfolded, somehow I feel at the unfolded position, the angle before it snap to a fully unfolded position is way more than previous gen (maybe some can confirm on this as my last fold is fold 4):
Admire the thiness of the device, when unfolded, it is merely the thickness of a USB C port. Totally impressed by it. However, if you always rock your phone naked without any case, the slimness and thiness will cause the opening of the phone slightly tougher as it takes me time to get a good grip to start unfolding it (at least in my experience). Feels like the phone will fly out of your hand anytime
However, the ugly punchole at the inner screen is back on this series. How I wish that Samsung can maintain the full screen display and work on how to improve on the clarity of the UDC as the punchole somehow will hinder the beauty of the display during media consumption.
The crease has also been improved this generation. Looks way less prononced, and less "deep". I tried running my fingers along it, and can really feel the difference, though I doubt that one will keep swiping at that area when using the phone
As usual, thiness and lightweight comes at a cost of the battery size and heat dissipation. The battery size is only 4400mah and we will only start seeing SilC battery on Samsung phones from S26 series onwards based on rumours. With the increased front display and inner display size, I believe battery life will take a hit. Will test that in the following couple of days, as well as the heat management and dissipation on such a thin phone. I am pretty sure it will more or less be impacted based on my experience with the S25 Edge.
All right, closing off for now, everyone here have a great weekend ahead! Cheers! Happy preordering!
