If you need to back up your Gmail ™ contacts, apps, etc., on your Galaxy A02s using Gmail ™ follow these step-by-step instructions. Backups can't be restored from a higher Android ™ version onto a phone with a lower Android version. From a Home screen, swipe up from the center of the display to access the apps screen.
The problem occurs when the watch reaches a certain percentage like 80% and it gets stuck. At that moment click on the message to reset the watch and choose backup watch. This will take you direclty to the wearable app setting to backup your watch and will then reconnet back to watch overcoming the setup screen. Hope its clear and it helps. Cheers!
