Why is photo viewing on any Android device so blurry?

[AC Question]

Why is photo viewing on any Android device so blurry? I noticed it first when I uploaded a profile picture on Twitter. I used a HD image but it turned out blurry. Also when I'm viewing eBay photos. Is there any solution to this or is it just how Android is? When I view on my Apple devices images are clear and fine.

Are you using Onavo by the way? This app shrinks photos by default, and you have to change the quality of the photos through the menu.
