I was in this very boat recently. My LG backup phone got bricked by an OTA. So I was left with a flip phone while waiting. My requirements were less than 300, stock android realistically two years out of the device. 4.5" to 5", smaller preferable, and a headphone jack. There was almost nothing like this. I ended up on the google pixel. However, it was difficult as I kept getting Verizon bootloader locked revisions. Despite them being listed as international or gsm unlocked. I finally found one in my upper bracket at 450, 128GB version. Its official support ends in October of this year. I've also read about a ton of hardware issues so I'm hopeful it'll hold out. Android phones are to me a shit show, to put it mildly. They're good, but not long term. I'm also leary of buying higher ended phones. I've had far to many times where my phone was knocked out of my hand at a bus stop. Then broken screen. The closest I've seen right now is oneplus or get a last gen pixel.
