Sony Xperia XZ4 rumors and leaks are coming by thick and fast and one of those rumors said the phone would have a really tall display and a very unique aspect ratio of 21:9.
The first batch of renders showed a 6.5-inch panel on a phone that would be essentially as wide as the Xperia XZ3, but stretch up to about 166.9mm, which makes it one of the tallest phones in the world. And the final size could be just as big as the iPhone XS Max, according to this tweet from tipster Ice Universe
