Archive: This article discusses mobile research published in 2015. Its percentages describe that period, not today’s smartphone market.

Before large displays became an ordinary expectation, the word phablet described phones positioned between conventional handsets and tablets. The label was awkward, but the design question was real: how much screen could a phone offer before it became inconvenient to carry?
What Flurry reported
In The Phablet Revolution, Flurry reported that phablets accounted for 20% of active devices in its March 2015 analysis, compared with 6% in January 2014. It also reported a platform difference: 36% of active Android devices were phablets, compared with 4% on iOS.
These are usage findings from Flurry’s dataset, not figures that should be relabelled as global sales. A dataset reflects the devices and apps observed by the provider, its category definitions and the period measured.
Why more screen was attractive
The appeal is easy to understand without assuming one size suits everyone. A larger screen offers space for text, navigation and controls. Someone who reads and watches frequently may value that space. Someone who wants a light phone that is comfortable in one hand may choose differently.
For developers, the task was to make layouts work across more dimensions. Filling extra space with a stretched small interface does not necessarily improve usability. Reachable controls, readable typography and useful spacing matter more than a category label.
Did large phones replace tablets?
The old headline suggested that phablets were eating phones and tablets. That wording was stronger than the evidence justified. A change in device share does not establish that each larger-phone purchase displaced a tablet. A person might own both, or purchase neither for unrelated reasons.
A careful interpretation keeps the trend and its limits together: Flurry observed rapid growth in a category within measured activity. That supported discussion about changing preferences. It did not settle the future of every tablet or establish one cause for changes in sales.
Reading historical research today
Use this as a snapshot of a design transition. For a current comparison, start with recent research and inspect its definitions before comparing percentages. Screen diagonals can also hide differences in shape and usable area. Historical categories should not be carried into a new dataset without checking whether they still measure the same thing.
When sharing a chart, keep its date, source and denominator visible. A striking percentage loses much of its meaning when the reader cannot tell whether it measures devices, people, shipments or sessions.
