I have a Fenix 7 Sapphire Solar - I’ve had it for just over 2-years and it’s been a great watch with no issues whatsoever:
However, in the last week or so, the start/stop button has really lost it’s responsiveness, it still works but I really have to press it hard and there is next to no ‘click’ anymore.
Ultimately, it still works, but it’s noticeably difficult to start/pause/stop an activity.
I have turned it off, soaked in warm soapy water, rinsed and dried the watch. I’ve also done a hard factory reset and repeatedly manipulated the button. All of the solutions haven’t really been that effective and the button remains ‘unclicky’; I fear that this will continue to deteriorate and eventually render the activity function unusable. Being over 2-years old, it’s obviously out of any warranty.
Any other ideas?
