My first one was a Samsung Galaxy S1 that I got in 2013 and it was a great little device that was easy to open up and repair. It had only 512MB of RAM but that was plenty for basic phone needs, web browsing and running some Android apps like AnkiDroid at the time.
My dad had the T-Mobile G1; if I recall, first ever commercial available Android phone!
That was handed down to me after a couple years. It has as much chill factor as it did nerd factor. People laughed and were amazed at the same time. I loved it, lol
