What I realized is, when I am lucky and I turn the card with 2 fingers for some degree, than zooming
is possible. When I put to 1:1 than the issue happen again. Try to zoom with fingers or + button.
Program quits with no error message.
I tried all versions beta/store ....
I have a Samsung S6, also with Android 5.02 and it works fine.
rgs.
