Since iPhone XR has 1792 x 828 resolution, does it actually have 1080p?
One thing is that, it actually might have lower resolution than iPhone 6 Plus, because iPhone 6 Plus has 1920 x 1080 Retina.
But if you consider that iPhones have been using Retina, you can say that iPhone XR's 1792 x 828 resolution is really 3584 x 1656 and is therefore way beyond 1080p. But can you really say that?
(If you can really say that, then iPhone 6 Plus actually have 3840 x 2160 and therefore really is 4k resolution?)
