My son's Gizmo watch 3 ran out of battery due to it not charging anymore. We tried multiple chargers, including two factory chargers, with multiple known good charging blocks. If I hold the side button down I get the low battery screen to briefly show up. There is no damage, physical or water, to the watch.
Instructions say to do a factory resent, but I can power on the do reset. What can I do to fix this?
