It seems that Google Analytics has directly addressed a concern raised in a previous blog post: that combined metrics for smartphones and tablets were not useful.
The Audience > Mobile > Overview report now breaks out “tablet” and “mobile” (“mobile” indicating smartphone) as separate values for the Device Category dimension.
“Mobile” encompasses a broad range of hand-held phones and even screen resolutions, since some smartphone display a high resolution within the viewport.
This simple but useful change in Google Analytics will enhance our understanding of our users’ technical requirements so we can provide them a satisfactory experience.
