Have an iPad Air that doesn’t have the white dot, I have a 10.5 Pro with a build date of Aug 2017, and I just started to notice a small white blemish 3-4 inches right above the home button. 🙁 I just noticed this within the past week, gen though its not as bad as other pics I’ve seen, still a little sad. I really use my iPad for multimedia consumption, so its not terrible, but on white screens its slightly noticeable.
