I’m kinda late to this bright spot phenomena but, just to ask, has there been any clarification on how/why the spots appear. It seems so random but is there anything at all that I can do to prevent it happening?
I’m curious that mostly (from what I can tell) these spots appear towards the bottom of display and around the home button which makes me wonder if there are pressure points where people would tend to press and scroll. Many of the photos I have seen show the spots being suspiciously close to where people’s thumb would naturally push/tap while scrolling etc. The home button would, naturally be subject to increased push/tap pressure also
I’m not suggesting those with this issue have been heavy handed with their iPad. Not at all. I am just thinking something with the lamination process in this particular model has resulted in an overly sensitive (to pressure points) panel?
I suspect that it’s caused by pressure from the display connector pushing against the back of the screen. I’ve noticed that when I hold my iPad naturally, my fingers that are touching the back of the device tend to be in the area where the connector is and where the spot developes, and if you hold the device with only one hand on that side, your fingers are especially putting a lot of pressure there. I am being extra careful about only holding the device with both hands, or if I do hold with one hand, I don’t hold it on the side with the home button.
Edit: Also, you generally squeeze that area when you press the home button. I don’t press my home button, but instead use the swipe from bottom gesture to go home, which is more natural for me anyways because I have an iPhone X and am used to that.
