My Garmin 45 battery ran down. I recharged it then turned it off and on but it froze. I couldn’t turn it back on. So I did the 30 seconds hold light button and connect to power to turn it back on which worked. Now every time I go to the heart rate widget it turns the backlight on. I can’t keep it turned off even with backlight options and a factory reset. It will waste battery turning the backlight every time I look at the HR widget. Any fixes for this backlight bug?
