The home button on my 6s Plus has some play and even makes this clicking noise when you push on it lightly, without actually pushing the home button in. Almost like it's catching on the area around the button or something. If I press the home button in a few times it might stop for awhile but it always starts again after continued use. I started noticing this when I would double tap the home button to enable the one handed use thing. Is this normal or a defect? It happens all over the circle not just on one particular spot.
