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.
HTC Evo 3D. My step brother had the Evo 4g and I was infatuated with it, plus by the time I was going to upgrade my iPhone 3G was dying.
I stayed with Android as my primary phone until like 2015 when I just kinda stopped caring about flashing roms and just wanted a phone that works. I still keep an Android phone with me.
