As this is a hardware defect, get in touch with your Local support team and they will arrange a repair for you.
If you have any questions regarding warranty, service routines and so forth, they will gladly answer these type of questions as well. If you could get back to me with which phone model you have so I can move the thread to the correct board here at our forum, that would be awesome.
Your question has been translated to English as this is an International forum.
I'm not quite sure that I understand exactly what you mean, would it be possible for you to elaborate a bit? If you could also get back to me with which phone model and Android version you have, that would be very helpful.
You can find this information in Settings > (Support) > About phone.
