Errors

There is an error with a change-over to the next question; one is left out sometimes and I have to answer the 10th question instead of the 9th, for example. So the answer for the 9th is empty and incorrect as a result of this error. Make an opportunity to return to those questions that user has not answered yet.
Then, the field is case-sensitive; any answer can be incorrect just because of the capital letter, but the first letter is capital by default and it is very uncomfortable to change it EVERY time.
And I couldnt send you a report because of another one error, like my phone has no Internet connection, though it has.
