Hi, The main camera on my Xperia XA no longer focuses properly, and makes a loud noise when the camera is on. The out of focus part of the image before the shot is taken looks like moving water ripples. All other camera functions still work (can still take and save photos, flash works, and the other camera works fine), and it's the same problem with another camera app (e.g. facebook messenger) This suddenly started happening, and I haven't dropped it, scratched the lens, etc. I upgraded to Android 7.0 about a month ago. Sounds like a hardware problem to me, but I'd be delighted to hear there's a more straightfoward fix. Thanks, Richard.
