Similarly, for me, android's killer app is that I can still get a phone with an SD card slot and an aux jack - so my music is with me, without needing to rely on a flakey old phone rightly condemned to the junk drawer.
I'm using a Samsung Note 10 Lite. Wacom stylus, SD card, headphone jack, and though the battery is ostensibly not user replaceable, a guitar pick will open the case. I love this phone.
Yes, my previous phone was a Samsung, and I dropped them because they no longer come with these two features. My current phone is a OnePlus (basically rebadged Oppo). I also considered the Moto G series, but their selection in Canada is awful.
