menu problem on Android

I found a problem with the menu on Android and perhaps the solution
I state: I’ve used Android 2.3 on a smartphone and Android 4.3 on a virtual environment (SDK)
The problem on Android 2.3:
The pages are loaded with the menu already open and there is no way to close it
on Android 4.3:
The pages are loaded with the menu closed and I can open and close but also with the menu closed I am able to select a link from the dropdown menu if I tap in an area where the menu should be.
Solution:

media (max-width: 979px) {/ * * for the menu on android /
.nav-collapse.collapse .menu-menu-container {
     display: none;
}
.nav-collapse.collapse.in .menu-menu-container {
     display: block;
}
}

After the solution on Android 2.3:
the page loads with the menu closed, I can open it but does not close after more
on Android 4.3:
It seems to work okay
Can someone who has Android test this before and after the solution to see if this problem (and possible the solution) occurs in a real device?
thanks
