Bugs in content types

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 : 

"Question set" embedded from Drupal to (allmost) "plain HTML". (Adobe Muse)

The main problem with the size of the "embedded stuff" seems to be solved, but it looks like that there is some other
"minor issue". When I come to the last question ant there should be a button "Finished", there is no button and its not
possible to com to the end of the questions.
