The native Android DatePickerDialog does not comply with WCAG 2.1 Guideline 2.5.5 - Target Size (Level AA), which requires a minimum target size of 44x44dp, or 48x48dp per Google’s accessibility guidelines.

Upon testing using Deque Axe DevTools and Accessibility Scanner, as well as manual validation with TalkBack and visual overlays, the following issues were found:

Individual day buttons in the calendar picker (e.g., 1, 2, 3…) are significantly smaller than 48x48dp in touch area.

This results in TouchSizeWcag violations, impacting usability for users with motor impairments or limited dexterity.

Verified across multiple apps using system/default DatePicker:

Google Calendar

WhatsApp

Skype

Microsoft Teams

This affects native Android DatePicker, not just custom views. While visually aligned, the tap area is too small, making it difficult for accessibility users to reliably select dates.

📷 Steps to Reproduce:

 Open any app using the default Android DatePickerDialog (e.g., MaterialDatePicker or DatePickerDialog).

Enable Accessibility Scanner or Deque Axe DevTools.

Run a scan with the calendar open.

Observe violations related to touch target size for individual day buttons.


Suggested Fix
Increase the minimum tap area (not just visual size) of day buttons in DatePickerDialog and MaterialDatePicker to meet at least 48x48dp.
