Android Web Browser

created a PHP/html code to open file manager to select and then submit to upload an image and it works very well on the editor via web browser plugin.

now when i tried to do it on android . simply… nothing. no pop-ups no errors , just idle like if the button on the web page does nothing.

did somebody dive into such things? please shed some light.

note: it works fine when open via firefox or the normal android browser. uploads images and all good. not inside the game browser tho.
