Total failure of this phone. I am very disappointed, because the telephone logs in three-weeks rhythms from the network and should log back into the grid only after rebooting. For my 11 year old daughter as a school support therefore unfortunately totally unsuitable. I struggle with the totally inflexible currently seller "Sellondo" to a change of the device, since only two unsuccessful repair attempts have brought any improvement. In addition, we a Polish unit was sent, although it was not seen as in the display.
