Samsung Galaxy S1 vs. S2 vs. S3, How The Galaxy S Has Evolved Over Time


There is no denying the fact that the Galaxy S series from Samsung is the most popular Android lineup to date. With its latest iteration of the Galaxy S, Samsung sold over 10 million units before the phone even launched. Obviously, a lot of people have become loyal to the Galaxy S brand. With that said though, lets take a look back at how the Galaxy S has changed over time to create that loyalty:

Both the hardware and the software side of things have changed dramatically over the years. But for the purpose of this article (and to make it easy), we’ll just focus on the hardware changes. Note that the first set of specs in each column are for the international versions of the Galaxy S series whereas the second set of specs are for the U.S. based versions.

Galaxy S1 Galaxy S2 Galaxy S3
Screen 4 inch SAMOLED (800×480) 233 PPI 4.5 in SAMOLED+ (800×480) 207 PPI 4.8 in SAMOLED (1280×720) 306 PPI
Processor 1 GHz single core Hummingbird 1.2 GHz Exynos dual-core or 1.5 GHz Snapdragon S3 dual-core 1.4 GHz Exynos quad-core or 1.5 GHz Snapdragon S4 dual-core
RAM 512 MB 1 GB 1 GB or 2 GB
Camera 5 MP, VGA front 8 MP, 2 MP front 8 MP, 1.9 MP front
OS Version 2.1-2.3 2.3-4.0 4.0-4.1

As you can see, the specs improved dramatically every year. With each generation, the screens got a little bigger and better (either through resolution or sub-pixel layout), the processors got faster and more powerful (higher clock speeds or more cores), and the RAM has pretty much doubled up with each new iteration. Needless to say, Samsung delivered with each and every Galaxy S in terms of hardware.

It is amazing to see what Samsung has done in just a few short years. By looking back at each generation of the Galaxy S and how it has changed over time, you can sort of get a feel for what will be coming in the Galaxy S4. I guess you could say this for any smartphone, but a better screen (maybe SAMOLED+ and HD resolution), a faster processor, a newer version of TouchWiz, and a better camera are probably all in store for the SGS4. And based off my experience with the older Galaxies, I can’t wait!
