Samsung galaxy S3 vs. Samsung Galaxy S4 – what’s the difference?
At first glance, there’s not a huge difference between the Samsung galaxy S3 and The S4 – their form factors are incredibly similar; the dimensions of the devices are pretty much the same and they have a similar look about them.
However, if you’re weighing up a purchase between the two, you’ll notice there’s a fair bit of difference in the price tags – £315 + VAT for the S3, £445 + VAT for the S4.
So what generates this difference in price? Is it worth paying the extra for the S4, or should you save a few quid and stick with the still impressive S3?
First of all, here’s a brief run through of the differences between the two. These are discussed in more detail throughout the rest of the article, so keep reading if you want to know more.

Size
Overall the two handsets are pretty much the same size. The main difference is the thickness – the S4 is slightly thinner – but the width and height are pretty much the same. The S4 is also lighter, but marginally so.
Display
Samsung has increased the screen size of the S4 by 0.2” to 4.99”. It has also reduced the bezel, which is why it’s possible to have a larger screen but smaller dimensions.
While a larger screen gives you more viewing real estate, it also creates a bigger reach from one side of the screen to the other. This can make one-handed use tricky at times. A reduced bezel can also cause you to accidentally touch the screen more frequently, so bigger does not necessarily mean better.
As for screen resolution the S4 definitely comes out the winner. It has full HD (1920 x 1080) and a pixel density of 441 ppi. This really does produce a crisp picture. The S3 isn’t far behind though; it’s got a resolution of 1280 x 720, which is still very impressive when playing back videos. Both handsets user Super AMOLED technology so there’s not much difference to draw in that aspect.

Unless you have been disconnected from the internet over the last few weeks you can not have failed to have noticed that Samsung have taken a serious barrage of comments regarding the memory or lack of usable memory on the Samsung Galaxy S4.
