This is my first smartphone and I was looking for one with which you may well edit emails and surf the Internet. Making calls is more important for me, I need only rarely. Apple is for me not in question, a matter of principle. At first I was a little startled at how quickly the battery is empty (in one day), although a good battery was certified in testing to compare this smartphone; but after I read in the instructions that only after repeated complete emptying of the battery reaches its full potential, I did it and now he holds 3-4 days. However, I have also turned off, things like GPS and Bluetooth (I usually do not need, it's nobody's business what, where I am), Wi-Fi I'm mostly just at home or as needed. What's in need of improvement, the instructions for use. Since it is my first smartphone (my company Blackberry I do not define as a smartphone), I had to familiarize myself only with the handling, in addition it was necessary to learn new concepts. Because I would have found it more beautiful when the terms were used in the manual and in the smartphone uniformly and not helpless sitting there asking yourself "what do the ???". The reason for this deviation is probably the most used version of Android because the manual was still an old version, and was delivered a new (4.x). Last weekend a new version was then plays and because the menu is again slightly different. About this Samsung Kies also import my Outlook contacts worked out fine. If I were to use the smartphone as a calendar with Outlook, which go with the Snychronisation also because I am confident. Overall, I think that's part of super chic, the display is really good and my requests (email, Internet) are fully covered. Hopefully my enthusiasm remains :-)!
