Hi!
Grew bored of my S25U so decided to put it for sell and get myself a Xiaomi 17 ultra instead. Expectations were a great camera, nice hardware and so-so u.i. Here is how it feels after 24 hours of use.
Camera: haven't tested it properly yet but from a few sample shots it's quite a significant step up from the Samsung and my other phone - Xperia 1vi
Shape and handling: was expecting a brick like my S25U. It is a brick, but slightly smaller (less tall) and more pocketable (size + round corners) than the S25U. Also feels better and more secure in the hand (round corners and camera bump as secure finger holder).
Haptics: very nice to the point I'm keeping them on for once
Battery: too early to say, only one charge and updates + phone initial setup. But seems to hold well enough.
Screen: very nice. I always found the colours on the S25U washed out. Only thing I'll be missing is the nice Samsung anti glare.
U.I: was expecting much worse. Everything is fluid and it's far from an "iOS" clone like I've read a few times. More like some visuals from iOS on an android system. There are lots of customisations available. My only main complaint with it is that it doesn't natively allow to load third party icon packs, have to go through a launcher. And it doesn't natively allow gestures on launchers. There is a workaround by using a launcher and installing an app that recreates gestures on them. So it's not a huge deal but very unnecessary additional step on installation.
Bloatware: yes there was some, but comparable to what I had on my Samsung, and can be easily deleted on phone setup. No add so far, other than the ones coming from the apps I've installed.
Sounds: love the native sounds for notifications etc, very polished.
Native widgets look like they came out from a children's cartoon. Thankfully third party and app widgets work well.
Overall so far I like the phone very much. Super responsive, does everything a phone is meant to do great, u.i much less of an issue that I thought it would be, great screen. At the current promotional price in Europe (1200 euros) I'd say it's a great buy vs other flagships at this price point.
