Two buttons in nav-buttons

I have a problem adding two buttons in ion-nav-button. When serving app everything is ok, but when testing on android phone second button goes bellow the header. I don’t have a title, but ionic does generate div.title and gives it width so that div pushes second button below.

Here is my markup:

<ion-view view-title="" hide-back-button="true">
    <ion-nav-buttons side="left">
        <button menu-toggle="left" class="button button-icon icon ion-navicon"></button>
        <button class="button button-icon icon ion-ios7-arrow-back" ng-click="$state.go('app.category-list')"
      Some content

Here is how it in browser(everything is ok), but on the phone “< Categories” button is displayed lower that the header.
Please help me resolve that issue.

Try to remove whitespaces between buttons, like suggest in this other topic: Multiple Navbar icons on android align vertically instead of horizontally

Work for me!
