After exactly four weeks, which is the smartphone in use, I can only report good: (1) Super-HD resolution - even when viewing TV channels live on other continents. Everything in sync, no jerking and no voice / image delays. (2) Faster processor - at the price a real miracle. (3) Voice quality: Nothing to complain about - is going well with the speakers, and the other person understands a from up to 3 meters. (4) sound - we were pleasantly surprised; without headphones you can hear playing an hour of music, without feeling as blaring. (5) photo and video quality: perfect for everyday wear; the video soundtrack is good. (6) Install and uninstall apps etc .: Intuitive and easy to understand and always fast. (7) Included accessories: As mentioned - the battery is empty even in optimization and "immobilization" of some functions after two days. But it's been so a spare battery in the box. Conclusion: For the price we paid an absolute bargain. I had a few more coins paid to handled shipping, handling and any necessary complaints in Germany to see. The broadcast came after three days, so very quickly at. The smartphone I would not hesitate to order again. Supplement: dual SIM operation also runs without problems.
