The software and the display are definitely the weak points at this unit. Meanwhile I get a replacement unit. The property Prev hung on permanently and no longer lies at the end of reset. Operation via the touch screen is much too sluggish MMN at the present time. The display resolution is much too low, just does not look good. Since it is old even by a few years smartphones Another usual. The unit will be the painting of imho modern smartphones (Visually, it is really top and the body is also valent), but this is in operation and quality of the display does not meet the above approach. If the phone is running does the telephone function, moreover properly. But instead reaches a device for 30 seconds.
