First Android phone was a Motorola Moto G4. Solid phone, great budget buy at the time. Replaced it with a refurbished Galaxy S9 in 202, which is actually still serving me to this day. My S9 is showing its age now, but I'm refusing to buy a phone that does not have a headphone jack, so I'm going to run it into the ground.
First Android device was actually a Barnes & Noble Nook Tablet (16GB storage, 1GB of RAM). Ended up running Jellybean, and finally KitKat, off of a microSD card to keep it going. Actually still have it, but flashed to Android 7. Gapps doesn't install, but I'm impressed it was able to run as well as it did.
