My wife had fair phone 4, and it was unusable. It was only time she replaced a phone prematurely. She cares a lot about camera though, and likes to take pictures. Her main complaint was that the camera took like 5 seconds to start, so she'd miss the moment. And when it did finally start the quality was really bad.

I tried using it a bit but I couldn't stand how unresponsive it was.

I don't know if their later phones have gotten better,I hope so, because I love everything about that company except their (previous) products.
