Bugs in content types

There is a bug regarding textual tips. They don't work (i.e. the user clicks on them and nothing happens) when the content type (fill the blanks or drag the words) is viewed on the start page of Drupal. They only work when they are viewed on a single page node view.

Has anyone else experienced problems with the scoring of multiple-choice questions (with multiple correct answers) using the stock browser of the Samsung Galaxy S4? I had a user report that her answers were not being scored correctly (and she had screenshots to verify), but I don't have an S4 on hand to verify. The question works fine on all of the desktop browsers and iOS browsers I've tested it on so far. 

Many thanks for any information or confirmation. I have an old SIII I'll dig out and test it on tomorrow, but was curious if anyone else has seen this issue.

First, thank you for great job.

Isn't it strange that in "Drag and drop text" content, when after a try (with error), you attempt a retry (by pressing the retry button), all the words to drag are sorted in the inverse order of the questions boxes one (an example at http://46.105.122.146/drupal/?q=content/test-drag-drop-text). See picture below *.

Incidentally, why are there these two notices when the user is disconected :
