I see here has been assigned no two stars. Then I make the time. No, jokes aside. Some users complain about the battery life: I can not judge because I've worried me a thicker battery with matching lid and the cell phone with it (not exactly tested) stops a few days. Software runs smoothly, what I want to install, can be installed also. Actually, I'm really happy with my first smartphone ... ... If it were not a trifle. Every now and then the error message that the SIM card (supposedly) was removed and the device must be rebooted now. Then I can do nothing and just click on the only available scarf surface "restart". After restarting the device is working then for a few minutes or hours, or even days also to the error message again. Until you get the phone out of his pocket and brought out randomly the error message has been seen of course you could not be reached (as if the phone is turned off). And what happens when I imagine my alarm to 6:00 and at 3:00 the error comes (and I fall asleep and can not press "restart")? The alarm clock then? Since I have no desire to find out the, I ask now getting a second alarm for the case. For a 250 euro expensive phone but I really expect that it is working properly. I'll exchange it once and report here again.
