To date, the Fire Phone remains my favorite Android phone. It had good build quality and worked great with Amazon infrastructure, like Kindle books or Prime videos. It had flaws, but I used it more than all my other Android phones combined. I still pull it out for Kindle books.
You know, the one product i want Amazon to release is Amazon Fire Phone 2. I know I'm in the minority here, but i loved the first fire phone. There was something special about the phone. I'll be honest, there was a lot of gimmick on that phone, but it was the good kind of gimmick, things that look cool... I also know it was a commercial failure, which is probably why they haven't bothered releasing a successor... Shall i remind them that the first Nexus phone was a mediocre phone that mostly went unnoticed, but the successors were much better phones and sold well enough... So Amazon could do something like that, if they want that is.
