Did you do anything that might have lead to the bitchiness of your implant? If I work a lot with my hands, I get some fluid buildup above my flexNExt, but it reads as good as before. A week or so ago, I caught the edge of the implant with my ring (very unpleasant feeling…), and since that time, the blinky in that area is a bit dimmed… not massively, but it’s visible. But it still reads fine with NFC Tools and NXP TagInfo, and opens up the link I put there when scanned with the phone.
And any idea on what may have caused this? I think a fatigue failure wouldn’t go away after some hours, so I’m really curious on what would lead to such behaviour… 
Still (and maybe I should have put that first…) I hope it starts working again… 
I know about Amal’s lifetime warranty, but seriously - I really doubt that I would do this procedure more often than neccessary…
