Hi. Just having some issues (sometimes) with a Motorola mc3200. Its a handheld scanner running Android 4.1.?. I'v got a small app (3 pages) with a couple of buttons and input fields. The scanner works and populates the input fields perfectly but the problem is with the buttons. I have a click event on them to change pages. Sometimes it will work but mostly not. I tried putting the page change into javascript with an alert. The alert always works but doesn't always change page. Any ideas ?
