Ok Zoltan, not sure about the rooting and blocking things, but I had to tweak it quite a bit to get it to count my steps, I got a Huawei by the way.

So the first thing I had to do was enable aggressive tracking, then I had to go into my phone settings and protect it in the power settings from being shut down when the phone is locked, and last I had to open the task manager where you switch between open apps and lock it, there should be a lock symbol to tap or you lock it by swiping it downwards.

It's still not perfect but good enough, check and see if this helps.
