Hello again,
Well, after further studies i found that the only images in mobile which is not lazyloaded is the html block used in the prefooter showing brands images. The wierd is that google pagespeed warning these as not lazyloaded only when page is cached. If not cached the images show up as not lazyloaded but google pagespeed does not make a warning for that.
I guess this problem is due to the LazyLoad standard threshold of 300px of the viewport.
Do you use the standard lazyLoad script and if so, do you have a filter to adjust the treshold?
