What’s one simple mobile UX code change that will help you get more form conversions?

Loading the correct keyboard for each form field is a simple yet impactful mobile UX change that significantly boosts form conversions. For example, an email field should automatically bring up a keyboard with an "@" symbol, and a phone number field should display a numeric keypad. This reduces user effort and potential errors, making the form easier and faster to complete. Insufficiently spaced form fields or incorrect click sizes on the submit button are also important for mobile UX, but they primarily address usability and accessibility rather than directly streamlining the input process as effectively as optimized keyboard types do.
