Amazfit Neo/PineTime reports incorrect number of steps in log

[jmlich]

I was checking Amazfit Neo if it shows stored data properly, but it seems there is some glitch (I was sleeping around midnight).

Also, PineTime doesn't store samples properly. It shows smaller numbers than expected.
In contrary, Amazfit Neo stores huge numbers. btw heart rate monitoring was turned on most of the time. Additionally, some pattern in data can be observed.

In my case it is usually expected values are 3000-9000 in this period of time.

I'll take a look regarding the problem with the Neo.
