but assuming it is an Android model, I suspect that your screen displays are similar to mine, and the "menu" button or icon is NOT one that is displayed on-screen, but is instead just below the screen akong side other touch-sensitive buttons for 'back' (left arrow), 'search' (magnafying glass) and 'home' (a little house). The 'menu' button is four, stacked, horizontal lines alimged on the right and the top line being longer than the others, extending towards the left. (It looks like a Table of Content representation.)

Use that menu button to get to the Export link.
