Fantastic phone. Love mine.
Great speed, massive storage (more than most laptops now, if you add a 128 or 256 sd card) perfect size (clearly anecdotal) being a good compromise between big and still manageable with one hand, full functionality, weather/water resistant, top-notch (though not “world-class”) photos, and unbeatable price. I paid $150 more (refurb from another site) a year ago, and I still have no regrets.
Caveats: no 5G. If that’s a must on your radar, scroll past. Likely no more Android OS support past 10 or maybe 11, if we’re lucky. And curved screen means standard tempered glass screen covers will not work - you’ll need a full-body case (avail. for like $12 on the bay).
But frankly, between the combination of Android 10, and the Note 9’s inherent functionality (FAR more than any other Galaxy), OS updates won’t be necessary for years.
