I have a form in mobile apps where I need to use inline validation but it's kind of annoying for users if it prompts error message (this field is required) even they don't key in anything inside the field. (just clicking the field and move to next field). The behavior for the form should be:
- required field message appeared after clicking submit button.
- inline validation only happen when user key in something in the field(this include invalid format etc wrong email format).
Is this good in UX point of view?
