Eliminate the Captcha when survey is taken on a mobile phone

Can I eliminate the requirement of selecting a picture (captcha style) at the end of our survey when it is taken on a cell phone ??

I did check your last edited form and you seems to be using cards form layout. The only option available is to disable "Show Captcha on Submitting Form" in form setting. Please check the screenshot below:

Please note that this will also disabled captcha when the form is accessed from desktop / laptop as well.

Thank you very much. It worked and solved my problem.

As mentioned earlier, this will also disable captcha when you use form in desktop / laptop as well.
