Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.
I suggest that you try to repair the phone software using PC Companion..
Before repairing your device you may want to backup your information first. Check out this topic for more information on how to.
How to backup?
If the issue should still remain I think that this needs to be examined and fixed at a repair center. For more information about how to submit your phone for repair and where, contact your local support team.
Can't really see any statistics over sent in phones unfortunately, but if a software repair doesn't solve the issues you should send the phone in to a service center so they can take a look at it.
This issue may occour if you have installed a 3:rd party software that's using the camera and is not closing it properly. It may for example happen with Snapchat.
To see if this is caused by an app you've installed that's not closing the camera properly, please try your phone in safe mode.
I still recommend that you try safe mode just to be sure. If you added a Google account during the setup guide it may have restored some apps.
If you have an SD card in your phone, also try removing that.
But if it happens without SD card and any 3:rd party apps i recommend that you contact a service location for further investigation.
