Plastic likely to be used extensively in the Galaxy S IV

The Samsung Galaxy S III is been incredibly popular smartphone for Samsung. One of the more common complaints that users have had about the device is that it feels rather flimsy thanks to the plastic case. Other high-end smartphones, such as the iPhone 5 and HTC One, use aluminum, giving the devices a more solid feel.

We’re sure there a lot of people out there were hoping that the Galaxy S IV might move to a more rigid metal frame, but CNET reports that the S IV won’t stray far from the design philosophy implemented on the Galaxy S III. According to Samsung executive vice president of mobile business Y.H. Lee, when Samsung looks at the materials it wants to use it doesn't only think about the aesthetics and quality, it also looks at how quickly and efficiently can you make the device.

Thin plastic frames and bodies would certainly be easier and cheaper to develop and manufacture. Samsung is also said to have had conversations about maintaining a removable back allowing the battery to be removed. Samsung maintains that using a thin and flexible plastic back cover for their devices makes it more durable than other smartphones. This claim comes from the fact that the thinner and flexible plastic can bend to better absorb a physical impact.
The Samsung executive stopped short of saying whether or not the Galaxy S IV would use plastic or move to more premium materials such as metal or even polycarbonate.

The S3 does not use plastic, but polycarbonate, and so will the S4.

Quite possibly one of the most incorrect statements I've ever seen.

Let me rephrase this for you to see how bad it was.
The iPhone 5 doesn't use metal, but aluminum, and so will the iPhone 5S.


Polycarbonate is a type plastic. So is ABS, and Delrin, and Polyethylene, and so on. They are all different types of plastic, just like aluminum, steel, copper and magnesium are all different types of metals. Now let me blow your mind. You can also blend plastics. PC/ABS blends with metal or ceramic fillers is also quite popular.

So what do you think "plastic" actually means?

FWIW, I do agree with the spirit of your post, that just because something is plastic doesn't mean it's poor quality. Plastic is a superior choice of material in many instances.

you're totally right, Polycarbonate is a type of plastic.
Sadly for the author, plastic, aluminum, polycarbonate are three different materials:
would use plastic or move to more premium materials such as metal or even polycarbonate

Because the majority of people think that way: (example: this article)
plastic: cheap material used for kids toys
aluminum: wooooow, super light silver metal
polycarbonate: woooow, difficult name, must be some special high tech NASA stuff

I said something wrong, but something which fits in peoples mind, so they might understand that the plastic used for the smartphone is not comparable to the plastic used in baby toys.

Fair enough.

But also keep in mind that the plastic used in most baby toys is usually an even higher grade.

Very few people take their cell phone and slam it into the floor and expect it to keep working. Have you seen the way babies and toddlers handle their toys? It's actually some of the better engineering on many of those toys.
