Ansich good, but unfortunately massive WiFi problems

Basically, I was very pleased with the smartphone. Camera, listen to music, the display was all really good and I was glad to have finally found a smartphone that satisfies my needs and not exceed my ideal size of a smartphone of 4.3 inches. Reason for the two stars and for the sale of the Sony Xperia Z1 Compact is the extremely low-speed WiFi. Fast surfing is so at home unfortunately impossible. By comparison, 8 other smartphones of different brands and price ranges in the same WLAN network were 5-6 times faster. A speed of 2-3 MB / s is simply not enough in order to be considered for fluid. B. a video on Youtube. In other WLAN networks that speed was not exceeded. The Xperia sent for that reason to Sony. Answer by Sony was that all device features meet the manufacturer's specifications. Well, too bad. So: Sold and not Sony more. For a Samsung Galaxy S4 mini acquired. WiFi speed at about 20 MB / s.
