Galaxy S10e. I love the small size of it and the fact that it still has a microSD slot and headphone jack. Its starting to show its age when it comes to battery life and the USB C port not working as good.
I like the Samsung android software with the customization that you get with Good Lock so I will probably stick with Samsung flagship for my next phone. The biggest thing I dislike with Samsung is the amount of bloatware they ship, the out of box experience is terrible and I usually have to spend a day researching what apps to disable with adb to get the phone usable. I will probably upgrade to an S23 next year. I usually buy my phones used when the model has been out for about a year. At a year old its still new enough to have plenty of support left, but its no longer the current model so it sells for less. Its a better value IMO then buying a new mid range phone, especially as there isn't as much advancement year to year in hardware these days. A year old flagship will have better cameras than a new mid range phone typically.
This is what I did as well. Bought an S22 Ultra a few weeks after the S23 line launched. The usual cons I found that I actually didn't mind. No expandable storage? 256GB is way too much for me; I can't fill that up with apps and photos. I also use wireless earbuds so I'm not mourning the 3.5 jack. I've always been a fan of the Note line so it's perfect for me.
I'm considering an Android smartwatch but I'm not doing research yet. I will also likely buy a previous generation device if ever.
I have never owned an Apple product, not even an iPod.
Although it's not Samsung, I consider the ASUS Zenfone 9 the spiritual successor to the S10e. It's got most of the same physical features (except the microSD slot), but with an updated battery, screen, cameras, charging, and processor. It is a bit buggy at times, the software update support timeline isn't quite there, and it has none of the useful Samsung apps/features like GoodLock, but for me the phone is still the best one I've had to date.
