T4 Blank and Ja Stark, as well as Ja Tour, have menus that work differently on Samsung Android phones. For T4 Blank and other templates also in your gallery, once you click on a menu item the submenu opens but it is not possible to close the dropdown by clicking on the menu item again, while on Ja Stark and Ja Tour it is possible.
The difference is due to the base.js file (pugins> system> t4> themes> base> js> base.js) which is different from lines 98 to 111.
I could modify the base.js file but how can you solve and have the behavior of the Ja Stark and Ja Tour menu without subsequent updates overwriting that file?
