I re-clicked every child manually from explorer to stop sharing just to make sure. now just one child gets problem to be shared. I share parent and it fails to be shared

windows while sharing

I did not need them in the first place, they were just there. I did not use Zinio either at all

it is possible to check by renaming the image in the phone or making its copy

I did that, there are no GPS tags in the images even I right click them to view the properties directly from the phone connected as USB storage. Do they keep GPS tags apart from the images and show them in phone gallery only?

I see, normally that permission is not required, e.g. standard keyboard on Sony Tablet S. It is not possible to predict whether keystroke activity is logged and sent unless you have source code of the application
