Hello Everyone🙂:
I have read the various postings about the "yellowing" of the screens, and this is a sad. It truly is. I remember the last time I upgraded my iPad2 to an iPad Air, I had to replace it 4 times because it had various problems with bleeding, and it would not turn on, etc.
To me, this sounds like a screen defect. What I learned is when I upgrade, I always test my iPad to its max, with various benchmarks, to see if I can get it to fail. If it does not, then I can rule out hardware problems, and narrow it down to the iOS.
There is also a bleed/dead pixel test you can run on not just the iPad, but on all the tablets, and I use it because it really pops out the brightest colors of the iPad. It is great! It shows you if there really is a problem with your iPad. I always run it on my iPad, and I do it at least once a month, just to be sure my iPad/iPhone are okay.
Here is the link to the test if anyone wants to try it out, and to see if you have a bad screen, or if your iPad is okay. Remember to follow the directions to the letter:

Thanks, and I hope this was helpful! May God continue to richly bless you and all those you love and care for and keep you all safe🙂
