Seems to be getting worse. I X them off and they come right back, but seem to stay off after six or so times.
They move them around so you dont become conditioned to unconsciously overlook them.I have a relatively small Motorola phone. At first they were big and in the middle, then they got smaller and at the bottom. Now I am back to getting mostly smaller at bottom and sometimes a little bigger in the middle. They do not always behave the same and seems they can be different on different phones and with different adds. Software is complicated...........
