Mobile phone camera again and again out of focus?

Hi. Had asked the question several times, but so far no one could help me.

I notice now for about 1-2 months, that the phone camera of my Huawei P8 lite 2017 is blurred or blurred. The lens is not soiled, there are no scratches and it is also strange that the inside camera works perfectly and still takes sharp photos.

Another unusual thing is that the camera is not consistently blurred, but in between times a few days, sometimes even just hours. Then often a very small crackling noise and the camera is blurred again. Since Saturday, my camera was sharp again, now it is blurred again. This problem also occurs in Instagram and Snapchat, so it's not the camera app itself.

I would be reluctant to exchange / send my cell phone, since it is only one year old. Repair I think will bring nothing, since obviously the lens itself is not damaged, but a software error is present. (I guess now, I do not know that exactly - otherwise I would not ask.)

Can someone help me? I also attached a picture so you can see how blurry the pictures are.

At first glance, it may look sharp, but if you look closer, you can clearly see blur.

Possibly. Is the lens design not quite firm. Can't even a specialist look over it and fix if necessary?

Do they do that in the media market?

No idea. I thought of such a tinker shop, they are hopefully with you too.

I would have to look, but I think they repair only something like broken displays.
