GPS/distance going terribly wrong when swimmimg, action button sometimes just not doing anything, screen going blank (thinking I'm not wearing it) after workout

GPS/distance going terribly wrong when swimmimg, action button sometimes just not doing anything, screen going blank (thinking I'm not wearing it) after workouts randomly, not to mention the original Alpine loop started to break completely in 6-7 months. I had NONE of these problems with older watches despite doing the exact same things.
