The smartphone industry is consistently evolving and we regularly see some sort of new stuff some of which becomes a trend and others are swept under the carpet. Recently, some stunning CAD renders showed that the Sony Xperia XZ4 comes with a weird 21:9 display ratio. Now, a new leak of the screen protector of this smartphone confirms its tall aspect ratio design. This leak was posted by @IceUniverse and this is a pretty reliable source.
