Created a mobile specific page to avoid reformatting issues but auto-routing there causes SEO issues

I was having issues with my site not formatting properly for mobile. To solve that, I have it re-routed to a page I made specifically for mobile. The issue now is that when you search in Google, the description that populates says "Mobile" before the site name and description. 

Is there any way to hide this, or is there a simpler way to resize images for mobile without affecting their appearance on desktop? Our audience is split down the middle between mobile and desktop use.

Thank you in advance for any advice you can provide.

We can use code to resize images on mobile, if you share link to page, we can check & give you code easier
