I just unboxed my new Garmin. After using two days, the upper left and lower left buttons on my Garmin Descent Mk3i remain stuck after pressing. They do not return to the normal position and feel jammed. Is that normal? What should I do?
definitely not, you should contact Garmin support.
After two weeks of diving one of the buttons felt stuck, although I cleaned the watch after every dive with fresh water. I put it in warm water for a while, then pressed each button several times. now it's fine again.
