One hand UI have a tendency do move to the left? topic

I am the only who experience this tendency? That the one ha UI function makes the navigation buttons at the bottom are to the left?
Often when u put it in the table often the navigation button are very often to the left. A bug? To activate one hand UI you need to use a quite rapid motion.. But obviously one hand UI activate when you put it on the table. I hope this problem is solved In the latest firmware (which is not accessible through official channels for eu devices)
