Tooltips on the input? No, but they should be able to lose focus of the input to hide the tooltip by tapping any empty space around it. Only thing I can suggest is instead of using field descriptions, which render tooltips, is to use the field layout parameters. Under Parameters > Layouts of your fields you can modify how a field displays in a particular view. You could use the below for example to display your descriptions directly under a field.
Code:
[value]
<div>Description here.</div>
