Phone client APP cursor in textbox

When opening a page in the Phone client app, NAV opens the page without positioning the cursor in the first textbox as it does in the webclient. The only way it does it , is by first touching the textbox on the screen. This quite a problem when the textbox is actually filled by a barcode scanner, we can't ask a user to first touch the screen/textbox before scanning a barcode.

Does anybody know how if and how this can be solved ?
