I don't know about others but I have not had too many issues with this phone and I still enjoy it as much as I first got it. The initial new wow factor has gone but as a tool in every day use it has been a very good experience and probably the best I have had using a Samsung phone in a long while. OneUI still has a lot of things I wish they would update, get rid of or change. That being said it is also the best experience I have ever had on OneUI and a lot of that has to do with Google's collaboration with Samsung. The S24 wouldn't be half the phone it is without Google's touch. It is like a really good hybrid of OneUI and Pixel UI.
AI stuff for some things is helpful and good but mostly over hyped and under utilized. So AI is not all that important to me other than speeding up processes, extending battery life while optimizing performance. I don't mind Gemini search and some of the photo editing tools. Beyond that it is not really that useful and has a lot pf privacy implications the more AI is integrated into the OS.
In other words I don't mind a relatively dumb AI but anything more than that I am not so convinced of the usefulness and am more concerned of potential privacy and security implications. So for now I am happy with everything.
We will see how things progress.
At the end of the day I just really enjoy the s24 Ultra. I have not touched my Pixel 8 Pro at all.... For me to ignore another phone is a huge deal, specially one I liked as much as the P8P.
If Google and Samsung continue to meld Pixel and OneUI with more similar features and animations I will likely, for the first time be a single phone user. I may sell my P8p and trade in my s24 Ultra for the s25 ultra and just have one phone. It would be new for me but if Samsung keeps giving good software and hardware I don't see a need for anything else.
Of course, I may just keep what I have a couple years and then trade and sell. This phone is as good as my iPhone 13 Pro Max which was my favorite phone I ever owned. Who knows, Apple may lose the top spot as time goes on but for now I have very fond memories of the iPhone 13 Pro Max.
