Description:
When clicking the "edit" button next to "Selected Date" on the picker to manually input a date with the edit text it is not possible to enter a valid date with the Samsung stock keyboard since the number keyboard that is opened does not allow to enter "/" or ".".

Expected behavior: It should be possible to enter a valid date with the keyboard, either by automatically inserting the special characters to complete the date or by using keyboard variant that supports these needed characters.

Android API version: 27 / Android 9.0
