Smartphones specialist leaks account @ OnLeaks Publishing on Twitter what they said the press images of the next Sony Xperia Z4, which is the first image of this definition we get of the phone.
The Phone seems largely similar to the Z3 and this is not surprising, where Sony used to make minor adjustments to the shape in their phones, only noticeable is the lack of microSD slot from the right side of the phone.
No information yet about the date of the release but the leaked specs are talking about 810 and 4 GB of RAM Snapdragon processor (and this is uncertain yet) and 21 megapixel camera accurately.
