A new report from Flurry breaks down the mobile market with a focus on the hardware form factor. It puts mobile devices into five categories: small phones (3.5″ screens or less), medium phones (3.5″ – 4.9″ screens), phablets (5.0″ – 6.9″ screens), small tablets (7.0″ – 8.4″ screens) and full-size tablets (8.5″ screens or larger).
It concludes that mobile development firms should focus their efforts on creating apps for medium phones and full-size tablets because those two form factors have the best combination of user install base and usage sessions.
On the other hand, phablets comprise just 2 percent of the install base and 3 percent of active users and usage sessions. “Phablets are a fad,” concludes Flurry.
