Making calls is tidy, you can install some apps (not too many) but that part torments himself up to 10 seconds to wait until the text is to be read just by opening the SMS. The Sony keyboard input is top notch and almost as good as Swiftkey I was thrown down immediately. Texts are so tiny anything to read into the apps that it is not worthwhile.
But now it comes: If all necessary and many unnecessary Google Apps (automatically) ge-updated were the smartphone is tight, ie no more memory left, WARNING, and nothing works. Tolle Wurst. Disable Automatic Updates necessarily else can you with the part arbeiten.Das is not as embarrassing for the manufacturer. And now all of Google to downgrade back to the factory versions and make no more updates (in PlayStore disable). Otherwise, the Xperia is useless !!!!!!
The impression remains ambivalent. For a little more money (10-20 euros more) you get for example now a new LG Optimus L7 II P710 constitute an offer in the bay and in an entirely different league play. I would, in my experience of smartphones dissuade that are so crooked configured. Rather a gimmick than a serious smartphone.
EDIT: Opening SMS and Whats App up to 30 seconds waiting time, but the best is the alarm clock goes on and the screen freezes, so that it can not be switched off. Especially when driving a real gag, thank Sony ;-) After a few weeks the Conclusion: Stay away, because my ZTE was better for 50 euros, which is cheap scrap the first order.
