Xperia SP Camera Focus Problem

[SonyLoversince2]

Hello everyone, 

I have a xperia sp phone. Everything was perfect until last month. My camera begun capture blurry and unfocused photos. When i called support centre, they answered me"you should repair your device by using Sony PC Companion" and I did. But, nothing had changed. 

Here some example of photos that I took with my xperia sp device;

Thanks for help!
