Here I find solution how to open Settings in iOS: How to redirect to ios settings in Safari use javascript in ios9
<input type="button" onclick="redirect()" value="Redirect">
<script>
var redirect = function() {
window.location.href = "prefs:root=Settings";
}
</script>
But there is some problems with this solution on my iPhone 6s plus 9.3.2(13F69):
- this solution doesn't work on my particelar iPhone, but work on iPhone 6s
- link to prefs:root=Safari
doesn't work
So I've got 2 questions:
- How could I find out why this solution doesn't work on my particular phone?
- How could I open Safari's in Settings app?
