Hi:
I have a 2 year old Surge which I use all the time. It works quite well. I have never gotten it wet, and I do clean the sensor screen as suggested by Fitbit. Lately I have noted. "Brown" sludgy substance under the sensor screen. Has anyone else seen this? The watch is working fine currently so I am wondering if this is something to be concerned about. Thank you for your help.

There are several sensors in your tracker, the one mostlikely to get clogged is the altimeter, on the back of the tracker you will see a small hole.
As for a sensor with a screen, are you refferring to the face of tye Surge?
