My Samsung Watch is wrongly recording me watching films or TV as sleep and I cannot delete the data. It's very frustrating as it changes my average and overall sleep data. Not useful at all for tracking sleep.
Also, is there any way to change the default time to actually time asleep rather than time in bed? The time in bed is not useful because I'm not actually asleep. I don't know who finds this useful for sleep tracking. Fitbit always prioritises actual time asleep and it was so useful. I'm finding the Samsung Health app and Watch tracking increasingly more frustrating.
