This is not a phone this a 4K LED with extra features in form of a phone.
SONY XPERIA Z5 PREMIUM is a new revolution in the mobile world.
This phone has a 4k display which is also first time in mobile and this has fingerprint lock, 4k camera, shining body, 3 GB RAMand much more thing that your smartphone should have in dreams.
This a phone which doesn’t fear water and dust. I purchase this due to its good looking and 4k features these were my main criteria.
but one thing I am telling you is that this phone is not faster then iphone6s. I choose this brand because this has 4k display first time on a smartphone.
