Garmin 530 up/down buttons triggering oddly

Curious if anyone else ever encountered this and I’m afraid I might not articulate this well. There are a couple of occasions where I’m trying to change workout screens but the page navigation buttons take me back to the main screen. It’s weird. Anyhow curious if others have encountered this oddity

Early production runs of the 530 had “sticky” button issues. I returned mine for a refund and splurged the extra money for the 830. Regardless of the source of your issue I recommend you call Garmin support. Doesn’t sound like the buttons are working correctly.

Might sound daft but how are you holding the Garmin? I’ve sometimes done the same when using my thumb to change screen but actually either my first or second finger has pressed the top left menu button and returned me to the menu screen.
