Samsung Galaxy Nexus

Abstract: The latest Android mobile phone under Google’s flagship phone line, the Nexus family, currently has a diagonal screen size of 4.65 inches (118.1mm). This follows a trend that Google started with the HTC Dream / T-Mobile G1 — their first Android flagship phone. Released in 2008, it had a diagonal screen size of only 3.2 inches (81.3mm). Since then, screen sizes in Google’s Nexus line have grown at an average rate of 0.48 inches (12.2mm) per year.

I. Introduction
In 2008, HTC released the first Android phone, the HTC Dream on T-Mobile[1]. Known as the G1, this phone kicked off the Android revolution. At the time, it featured a screen size of only 3.2 inches (81.3mm) — which is rather paltry by today’s standards. Since then, subsequent releases of Android phones by Google and its partners have featured larger and larger screen sizes, culminating with the Samsung Galaxy Nexus[2], announced earlier this week in Hong Kong.

II. Methods
For this experiment, we only used specifications data provided by Google and its partners to determine the screen size. We listed each of Google’s flagship phone ordered by release date. Then we divided the total change is screen size by the total number of years.

From there, we’re able to extrapolate the potential screen size of future Android phones.

III. Results
Here is data from all of Google’s stock Android phones.

  • T-Mobile G1 (2008) – 3.2 inch
  • Nexus One[3] (2010) – 3.7 inch
  • Nexus S[4] (2010) – 4.0 inch
  • Galaxy Nexus (2011) – 4.65 inch

We see that over the course of 3 years, Google’s phones have gained a total of 1.45 inches (36.8mm). This factors out to an average growth rate of 0.48 inches (12.2mm) per year. With this result, we can now predict the screen size of Android devices over time.

  • 2012 – 5.13 inches (130mm)
  • 2013 – 5.61 inches (142.5mm)
  • 2014 – 6.09 inches (154.7mm)
  • 2015 – 6.57 inches (166.9mm)
  • 2020 – 8.97 inches (227.8mm)

IV. Conclusion
Over the last few years, it’s clear to see that the market has spoken with regard to its preferences over the size of mobile devices. Google has recognized consumer’s preference for larger devices and has moved toward a “bigger-is-better” strategy for mobile phones. At the current rate of growth for Android phones, by 2022, they will eclipse the 9.7 inch screen (246.4mm) size of Apple’s tablet, the iPad[5].

V. Footnotes

Seeing this post on Gizmodo earlier today made realize something. Android phones are getting bigger and bigger. So, I decided to write this tongue in cheek “research paper” to highlight the increasing “screen bloat” of Android devices. Bring on the 9.7 inch phones, baby! 2022 can’t come soon enough.
