Removing a spot of super glue from my 5 screen?

You could try to gently scrape it off using an 'old style' razor blade or a small, hard plastic spatula, the emphasis being on gently. Do it multiple times and do not attempt to do it in one go. Super Glue sets solid so this may work.

Do not attempt to use any solvents as these will likely damage the screen coating.

Chamar has very good advice. Just use your finger nails, it will simply scrape off.
