!Devices are not used the same display protection and I got them from different stores.
The iPad, the older in my own. It came from apple store website Thailand and it’s sent directly China. The protection by Sview clear. Next, The iPhone (While) bought from apple store website Thailand , waited abort 2-3 weeks sent from Singapore and protect by Focus clear color. Then the iPod (Black), the younger in the family. I bought for my father at iStudio by Spvi. The protector, it came with frame.
The color of the iPhone clear and vivid.
The iPod tones color seem like blue sky but the iPhone like yellow. I think screen of iPods are should similar to iPhones.
I believe that the colors are unusual because the screen protections and I would like tone color display of iPhones more than iPods or iPads.
