I'd like to write down my experience with the S24 ultra.
I have been an iPhone user since 2010. I only tried an android during the galaxy S4 days but quickly returned it because it was not polished and back then iOS was much better compared to Android. I have had iphone 4, 5, 6, 7, X, 12 pro and 14 pro.
But after so many years, even if the product in itself is good, it became quite boring. I saw all these cool phones on Android come and go meanwhile my 14 pro wasn't that much different than my 12. I noticed that I like the UI aesthetic of oneUI because it looked polished and a bit like iOS and Android wasn't the same anymore as in 2012.
So end of January I purchased a S24 ultra. Very good phone. But after about 2 weeks I missed my Iphone, mostly because majority of friends and family used one. So shared albums, airdrop, imessage was gone. I live in Europe so Whatsapp is really popular here too but it was more than just imessage.
I also have ipad pro and macbook pro but noticed I don't use them that much to force me to stay on apple. It was mostly family reasons.
Anyway after about 3 weeks I returned my galaxy and purchased iPhone 15 pro max. I got used to the big screen so went for the max for the first time. It felt nice having the things back I missed. But you can already see it coming. I started missing Android too. Even if the iPhone 15 pro max was still the best iPhone ever made, it was still 99% the same as my 14 or even 12, save for the dynamic island.
So what did I do then? I bought a S24 ultra again and carried both at the same time for several weeks.
I noticed that if I have both in front of me i was more inclined to use the S24, unless I needed to do something only my iPhone could but this hardly ever happened.
I like the bigger screen, the status bar, the gestures like back button, app drawer, swipe for notification center.
So currently my iPhone is only used when I go to the gym because I have airpods pro. Those fit much better for me than the galaxy buds 2 pro. I see myself switching again after some weeks to keep it fresh though but carrying 2 phones at the same time i won't ever go again. It felt so stressed for me.
I am interested in the iPhone 16 but it will probably be minor improvements yet again and iOS 18 will come to my 15 pro anyway.
I have turned to using workarounds for the fact that my family uses iPhones. Texting is whatsapp which we all have anyway. Icloud photos are now google photos. We all have a google account anyway so I send using that. Airdrop and so on I use quick share with the qr code. I gave my apple watch (which I didn't use that much anyway) to my wife. I feel sorry for the people wanting to switch but can't let go because of pressure from family.
What I wish is that samsung just improved the consistancy of the camera. With iPhone you knew what to expect but my S24 could sometimes completely expose wrong. And the zoom camera, although good in good lighting, is really bad moment it gets darker. Skin tones become orange like which I really hate. For photos I still prefer my S24 but videos is hands down my iPhone.
At the end of the day, what iOS is known for is true for me. A bit more polish, (some) apps have a better UI, but you also give up certain things to have that.
