Sony's Xperia Z5 Premium has a gorgeous, pin-sharp screen, it's powerful, packs a solid camera and won't die when you spill your drink on it. The Bad Its 4K display results in a sky-high.
The design of the Sony Xperia Z5 Premium is pretty lacklustre. There's nothing inspired, like some of the flourishes on the Xperia Z5 – I don't understand why Sony didn't decide to.
