Radio buttons too small on mobile device

I've increased the font size, and the questions font increases, though the radial buttons and corresponding text is very small and hard to click on a mobile phone. Is there a fix for this by any chance?

I have tested your from on my Samsung Galaxy S4, but i was not able to replicate mentioned issue. I could select radio button options without any issues. 

However if you would like to increase size of radio buttons, inject this CSS code to your form:

input[type="radio"]{

width: 20px;

height: 20px;

} 

Inside of this guide you can find how to Inject Custom CSS codes to your form:

After you add this CSS code radio buttons on your form will look like this.

Here is my demo form where I added mentioned CSS code: https://form.jotform.com/61544297899980
