Inconsistent Keyboard Behavior in DropDownList Filtering on iOS and Android

on‑screen keyboard does not automatically appear when tapping an input field on iOS, while the behavior differs slightly on Android. This issue occurs when filtering is enabled in the DropDownList component.

We verified the reported behavior on both platforms using the following sample:

Replication Procedure:

  1. Open the sample in both android and IOS device
  2. Tap the dropdownlist input
  3. you can see the difference

Expected behaviour:

When the user taps on the input field, the dropdown popup should open, and
the on‑screen keyboard should appear automatically, allowing the user to start typing immediately.

Actual behaviour:

IOS:

  • On the first tap:
    •  The dropdown popup is displayed.
    •  The keyboard does not appear.
  • The user must tap again on the filter input inside the popup for the keyboard to appear.

Android:

  • On the first tap:
    • The dropdown popup is displayed.
    • The keyboard does not appear initially.
    •  Tapping the filter input once triggers the keyboard.
  • From the second interaction onward:
    • Tapping the input field automatically opens both the popup and the keyboard without requiring an extra tap.
