Looks like Sony decided to move upways to increase the resolution of the screens of smartphones still a little bit, although it would seem - so far further. There was a mention of the 5K-screen - its owner called the model J8220, codenamed “Xperia 1R”. Perhaps this is the next flagship - Xperia 2.
The screen has a resolution of 2160x5040 pixels. For comparison, the 6.5-inch screen of the current flagship Sony Xperia 1 has a resolution of 1644 × 3840. It turns out the same aspect ratio of 9:21 and absolutely crazy pixel density of 899 ppi.
What kind of vision should one have in order to appreciate it?
