@Marcy I'm sorry to hear that.
Have you tried to perform a software repair using PC Companion as suggested earlier?
I purchased the phone end of january and now the front camera is not working, just over month brand new. I have tried a number of fixes I found online but none of them have resolved the issue. The front camera icon does not show, selecting AR mask or style portrait (which uses the front camera) returns an error message, camera not available or camera not available, flashlight or camera may be in use by another application. Close it and try again.
Fixes attempted;
Clearing camera cache
Powering on in safe mode
3rd party camera application (front camera icon does not show)
Factory reset
@RandomRash I'm sorry to hear that. 
I would suggest that you try to perform a software repair using PC Companion as well but if that doesn't help I'm afraid it sounds like your phone is in need of service. You can contact your Local support team for information on where you can find an authorised service center and how to proceed from here.
@Adelahmed If the previous suggestions in this topic didn't help then you need to get your phone examined at an authorised service center. Your Local support team can help you proceed with this.
Guys,
My girlfriend has the same problem: Camera used by an other application...
I however don't have this problem. The only difference is she is allready using Android 6.0 and I'm still using 5.1.
I assume its the update to Android 6.0?
And yes, where are both using a Xperia z5 Compact.
Ps: My girlfriend just switched from an iPhone 5 to this a few days ago, not a good start :smileyd_oh: 
@J10ne Sorry to hear that. 
If none of the previous suggestions in this topic helped you should contact your Local support team, or your retailer, about this.
Hi @FrankFrankFrank, sorry to hear that.
If a software repair using Xperia Companion didn't help I suggest that contact your Local support team for more information on how to proceed with this.
