Since software v3.5 (or perhaps even earlier), I have ignored the sleep data as they bear no relation to actual sleep. Sometimes the Vivosport claims I have only slept for an hour a night. Anyone else seen the same issue?
I have the same problem and the accelerometer now appears to be over sensitive. If I get up to the toilet it thinks I have got up and started my coffee..!! The change started with the addition of the REM sleep ' improvement'; and my Vivofit 4 which does not have optical heart measurement capabilities works perfectly to record sleep.
Do you find any work around or answers to this problem?
