The S4 Mini was 7 months old, as it lies no longer be switched to silent mode. In addition, it remained just hang often. So the battery had to clean out and back so it went on. We have sent it to repair, with the indication that this is a hardware problem must be. After 4 weeks (!) Came the cell phone back without having fixed the bug! Only a software update has been made, we can own. Meanwhile, the mobile phone is again two weeks from the merchants. Who has just obtained from the manufacturer, if he can send in the phone for repair !! The phone we needed professionally, emails etc.
My recommendation: Stay away from the dealer Notebook.de! Such rubbish I have not experienced in the past 15 years as an Amazon customer !!!
