"The onKeyDown event in mobile browsers may not provide the
desired event arguments, such as the key code or character, due to the limited
keyboard options on mobile devices. This is also the intended behavior in
native <InputText> elements. An alternate solution for capturing keyboard
input on mobile devices is to utilize the Input event, which is triggered
whenever a user interacts with a Syncfusion TextBox."
