About four months ago when I tried to use the ECG app which appeared, by pressing fingers on the corners the watch screen went blank I would see a green line across the face, and then see the fitbit logo. Then nothing. I discovered when I got home that is I connected the charger cable the watch would boot all appeared normal. Unless I tried to use the ECG. Same process to restart. Then about a month later when I would go to check the time, pressing the button. The watch would reboot.
