Eliminating the nav-bar with tabs

I have based a small app on top of the tabs template, but having weird issues with the nav-bar.
I dont want it. Im very satisfied with the Tabs button by itself, without the header which is useless as it just shows the title of that same tab, and its a waste of space.
I tried doing the following in my index.html:

<!--<ion-nav-bar class="bar-positive">-->

But then I see the following behavior:

  1. in android app & android browser - a white space in where the nav-bar was
  2. in ios browser - looks ok, no white space
  3. in desktop browser - looks ok, no white space

Im not sure how to approach it, how can I remove the nav-bar completely?
