I have a Garmin Venu that I purchased a year ago and after a recent update, it seems to be flickering at random times. The screen goes blue and the flickers alot. Sometimes its not even possible to restart the watch . Hard reset works sometimes but I am unable to see my screen most times. On some occasions I see some apps on the screen but half of the screen flickers . More often it flickers randomly and not when I particulary start an activity. Is this a software or some hardware issue ?
