Hi @bhp1552,
As this is an international community I have translated your previous post in to English using Google translate, please keep all future post in English.
I'm sorry to hear this. I recommend that you perform a software repair using Xperia Companion to see if this behavior is caused anything software related in your device.
If you are still experiencing the same behavior I recommend that you get in contact with your Local support team or retailer for assistance with having your device sent in to an authorized service center for repair.
Let me know how it goes.
