Just opened a brand new 6S pro and side button with associated spring fell out. Good quality of the product.
You're one in a million :D
My guess is...they'll send ya a new one
Or they say you dropped it and let you suffer :)
They did not care. I did not drop it. I was setting it up. It is going back.
I was joking right? Garmin is the best with warranty, really super good how they handle things!
