Can you add
<style> body { -webkit-touch-callout: none; -webkit-user-select: none; -khtml-user-select: none; -moz-user-select: none; -ms-user-select: none; user-select: none; } </style>
to your HTML code? This should prevent the dialog on both iOS and Android. Moreover, you can set the “disablecallout” to “true” in the iOS project.
