Strange steps measurement in iphone

Question

Does someone have an explanation for this strange step measurement which is happening in my iPhone?

As you can see from the screenshot here reported, for some days in this month the steps counted were exactly the same (I have noticed that this happens frequently).

Clearly, it is impossible that the phone counts the same number of steps for consecutive days. I think this may be an average value computed due to missing data.

I checked the actual amount of steps for those days and it is always the same fixed value.

Is it normal? Can I avoid this to happen?

This issue fund is in fact a bug. I have reported it on bugreport.apple.com

I guess now, they are taking care of the problem...
