Samsung Galaxy S4 vs Samsung Galaxy S III

The Samsung Galaxy S III was an absolute smash-hit in 2012. Few were the Android smartphones that dared to challenge it, and even fewer were those that stood any chance at all. However, time has once again proved that nothing lasts forever, as we're now 2013, and the good old GS III is now much less impressive than it was a year ago. But that doesn't mean that another company is to steal the crown from Samsung. Nope. Sammy has been refining and improving its billion-dollar formula, and the results of its efforts are evident in the Galaxy S4 – a handset that seems absolutely worthy of succeeding the wonderful Galaxy S III.

OK, so the Galaxy S4 is an amazing smartphone worth every penny, but there certainly are a lot of folks out there who are still rocking the GS III. Should those guys think about upgrading to the GS 4, or are they OK with their GS IIIs for another year? Enough questions! Let's go get ourselves some answers!


We've all heard people say that the GS III and GS4 are almost identical in terms of external design. Well, this is so not true! OK, the Galaxy S4 is certainly in the same style as the Galaxy S III, but it is significantly better. Not only does it look better, but it is actually a bit narrower and a bit thinner than its predecessor, while sporting a bigger screen at the same time! This alone is an extraordinary achievement by Samsung. And as we said, it actually looks way better with its thinner bezel, more symetric design and better key layout.

Other than that, both devices are made of pretty much the same plastic material, which should be polycarbonate, though whatever it is, it sure isn't very tough, so you'll have to be extra careful with both of these guys.

Both handsets have the same key layout, and unfortunately, the Galaxy S4's keys do not feel any better than those of its predecessor, so no major construction upgrades here. Samsung has also decided to keep its favorite touch-sensitive Menu and Back keys, positioned to the left and right of the Home button below the screen. We actually tend to like this configuration, as it doesn't take up precious screen space.


Even though the Galaxy S III's display looked amazing last year, it's now somewhat weird compared to the 1080p panels that start to overtake the market this year. That includes the screen of the Galaxy S4, which is so much better than the one of its predecessor. Not only is it higher-res, but it also boasts more natural colors that are still vibrant, but not to the point of being artificial and unpleasant.

It's not like the GS III's display is bad, even by today's standards, but the one of the GS4 is better in every aspect.

Sony and HTC and Samsung are the phones with most features, apps and games.

Most phones have a big screen and rounded corners, so it makes the S4 look like a lot of others too following that logic. But it's texture, screen dominance and more rectangular build makes it noticeably more elegant than it predecessor.

On a real note, Samsung needs to start trying with their designs. The plastic is ok but we all know Samsung can do better.

No this isn't the iphone 4, 4s which you can never tell the diffrence unless looking at the top where it doesn't have a line on the left side® Why the Troll,,,,? It's still using Android, like Htc Sony Lg Samsung and all other oems. Why the hate? ™

'Coz Samsung haters(mostly Sony, HTC, Nokia fanboys) think that it's Samsung's fault why their fav oems are struggling to compete in the market.

Typical fanboy speak! Did it occur to you that it is less about hate or market position but something as simple as customer satisfaction or different needs/desires about what people want to get out of their experiences with their handsets! I have no problem with the product but a mountain load with the manufacturer and its attitude to customers. That arrogance of Apple fanboys is seriously affecting Samsung fanboys. Our experiences inform our choices and I loathed my experience with Samsung and even if I bought its product, I will do so with eyes wide open and pray I do not have any problems as I would not want to deal with them! I do know this, HTC will listen, send out UPS to collect the product, examine the complaint/investigate and send you your phone back throuh UPS, no questions as will Sony. Samsung? Please take the product to an Independent Service Centre, authorised but not affiliated to Samsung. You get that way when your S3 cracks unexpectedly by the charger port and you end up paying £134 to fix it.

p.s. a work colleague has a similar crack in the same position on her White S3 but thought it was part of the design........disavowed her of the notion and she is now one unhappy customer!

GS3 users will realize how laggy the GS3 is when they try out the GS4. Android OS really do need the 4 cores running at full bore +2.00Ghz to feel right and run normal.

And as soon as they push a os update to the s4 it too will be laggy
