While developing using ngTouch in an angular project I found that when tapping on a form field to enter text the keyboard would open and immediately close. I looked into ngTouch and found that line 308:

    // Blur focused form elements
    event.target && event.target.blur();

Was causing this. Once removed everything worked fine with no issues in my project. May want to look into a work around that would still allow function with iPad text entry.
