Happened to me. Had to keep checking it, thought my eyes were going bad. Emailed Fenix-Store, got a return number and sent it back. One of their staff emailed me on Monday and said that they repaired it and are returning it. Something to do with securing the bezel. I'm not exactly clear what the fix they did was so I can't tell you precisely what they did. However, if you bought it from Fenix-Store, they will resolve the matter for you.
I was praying that they return it. The Fenix-Store return address is in Georgia and our home team (University of Hawaii Warrriors) is playing Georgia in the Sugar Bowl. (Nah, they will!)
Aloha and good luck!
