I've only had the watch since mid-February, and all was peachy. I had minor quibbles with how software handled the information, for instance, the fact it doesn't autocalculate resting heartrates, enabling workout detection disabled location tracking in Samsung Health, and the heart rate interval is 'battery-destroying' or 'what's even the point?' This was, until around the beginning of April or so.
Since then, the watch has been intermittently, but mostly not tracking my sleep. If it had, it recorded maybe one- or two-hours. Looking on the heart rate monitor, it tracked my heart rate throughout the night, but always stops for between twenty-minutes and an hour or so, around about six- or seven-o'clock in the morning.
Naturally, I tried all the usual troubleshooting: resetting, unpairing, uninstalling, reinstalling, pairing, clearing caches, trying another app store, ensuring high battery charge, but to no avail. When contacting support, they also, inevitably, went through troubleshooting, checking for updates, checking the settings, clearing the cache, damage, even getting another person in my household to wear it, then deciding they wanted to inspect the phone instead.
More noticeably since then, the watch has, despite DND and vibrate being turned off, begun vibrating occasionally. I think this is due to it disconnecting, but I believe ~1m is well within range for bluetooth, and my phone is not connected to another bluetooth device.
So, I'm at a bit of a loss! Any help would be greatly appreciated because at the minute looks like I'll just be selling it and investing in a fitbit inspire HR.
Tl;dr: Not recording sleep properly; heart rate not being recorded at the same time each day; already troubleshooted lots; weird vibes
