I'm not sure if it's too late to answer this, but you can force Blogger to open the desktop version on mobile devices.
Here's how:
Go to Theme from the left menu. Next to the Customize button, click the small down arrow. From the dropdown, choose Mobile Settings. When it asks, "Do you want to show the desktop or mobile theme on mobile devices?", select Desktop.
If you need a small hack, simply add this <html> code inside the <head> section, preferably after the other <meta> tags:
<meta name="viewport" content="width=1024">
Typically, mobile sites set the viewport to width=device-width, which adjusts the layout to fit smaller screens.
By setting it to a fixed width like 1024, you force the browser to render the site as if it's on a full desktop screen.
