I was also searching for this. I noticed it as well and almost always it is traffic from phones or tablet (mostly Android) that are mistaken for bots. Indeed in Google Analytics the same.
Did you already find a way to ‘unbot’ these and mark them as genuine traffic (humans)?

Thanks! I never heard of this, but did some reading and I think this might be case for my website. Trying to filter them out and see how it works after that.
