Really thanks for your attention. I've to improve my communication skylls. My fault. I'm sorry.
In the pages 3 to 7 you will find the questions with advanced ranking. There no problem answering in a computer with a mouse, both drag an drop or double clic.
The problem is answer it in a mobile phone, when you start dragging and dropping, the screen scrolls a bit, and makes dragging and dropping difficult (not impossible).
I have tried templates suggested in other posts of this forum and the same thing happens.

I've read some posts in the forum about iPhone question, but also happens in Android devices

I've just write if someone recently have the same issue in Android and find a solution.
