Very good phone, which feels good in the hand. Small but powerful, application that runs better on my Wiko Hightway 4G while on paper the Sony Z3 is supposed to be less powerful. Everything is fluid on this mobile and battery ..... what a joy. Almost five days of autonomy compared with 1 day with the Wiko for the same use. Certe Z3 is Sony's expensive but at least it works very well and is very complete. I heartily recommend it. A minor complaint says this is the connection for charging. A charging station is soon forced to buy to avoid damaging the clapper that protects the micro-USB plug to force open and close.
