Its amazing to see some people having issues with the XZ Premium.
I got mine on contract last July at the Carphone warehouse so I could get the CHROME version.
You know I have not had a single problem with it-not one! Its super fast and even comapred to other phones at the same price range, it simply beats the PANTS off them in terms of speed.
Samsung have a lot to catch up with this phone in terms of speed and they know it. I have had the Z 5 premium fast0-but got warm on long user, the XA and the L1 (as a spare) and Finally settled on the XZ PREMIUM last July! Will never go to another brand if Sony keep on producing flagships at this quality and speed.
Youtube any speed comparision of this phone against of ANY smartphone apple/or android and it beats the lot of them in terms of speed. Goodness knows what Sony have done to make it so fast but it is. After trying a samsung S8+ and its LAGGY UI compared to the XZ Premium i'm a sony xz premium fan for life!
