I've also noticed this, however the issue for me seems to be that I can't get the camera app to use the telephoto lens.
I'd initially assumed that the three zoom numbers correlated with the three different leaf icons that we used to have. However, now that I've looked further that's not the case for the telephoto.
I tested this by covering the wide angle lens, and switching to it - sure enough, just my finger. Moved my finger across to the middle lens, switched "x1", sure enough, finger. Moved my finger to the telephoto lens, press the "x2" button, and I still see the picture, indicating that the phone didn't switch to the telephoto lens, but it's just digitally zoomed in the standard lens picture (which explains why photos taken this way look poor).
Does anyone know how to get the phone to use the telephoto like it used to?
Ignore me, I'm an ***** - the act of putting my finger over the telephoto lens meant that the phone decided that there wasn't enough light to use it, so continued to use the normal lens...
