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.

Plastic phones last longer...

A phone made with a properly designed plastic case is likely to last longer due to the plastic being more forgiving and also by being lighter. It's true the phone doesn't feel as substantial as phones made with aluminum but as long as everything fits well together and the phone holds up, I think it's great. Phones with metal bodies tend to break easier which kind of defeats the purpose of having a "more substantial feeling" device.

I agree. Plastic or metal, it really doesn't matter to most as most people will purchase some kind of cover to protect their investment. All it takes is that one drop by accident and you now have a chipped/scratched/dented $500 piece of equipment. I have dropped my SGS III once and glad I have my otterbox in place. When you go to resell the phone and upgrade later, the body of the phone is in just about flawless condition when a case is used as it takes the everyday abuse.

So while metal phones are nice, its not a deal breaker to me.

Funny, but most of the Rolex's made in the 70s and 80s used acrylic or hesalite crystals. And many of those are among the most desirable vintage.

So your attempt at humor is a failure.

And another thing. Rolex would never use Aluminum in a case design.

You're stretching, as usual.

Samsung should just one-up Apple and make the whole phone out of glass, not just the front and back.

Why the hell did Apple put glass on the back of a phone, anyway? People are either going to put a case on it to protect it, or they're going to put a case on it to hide that it cracked because they didn't have a case...

I think you're right - if you want to ponse about in an attempt to impress shallow minded onlookers with jewellery, then metal is probably the way to go. On the other hand, if you want a device, be it watch or computing device, primarily to perform a function, then material aesthetics give way to price, durability and quality and extent of functionality.

So you would rather have a less durable, heavier phone so you can feel superior?

If apple had plastic, and samsung was metal, then you would be touting plastic, but since it is the other way around, well this is what you get.

I would like to see some evidence that your tictac case is made of the same material. While it may be plastic, there are so many grades of plastic, that I highly doubt they are the same composition.

From my experience: Every single person (at least 15 that I can think of) I know with an Iphone or ipod has broken at least 1 by dropping it from short distances, while my cheap plastic Samsung has been dropped so many times, and still looks brand new. I will take that any day.

Tic Tac containers are polystyrene/polypropylene but most drink containers are indeed polycarbonate :)

Polycarbonate has many formulations, just like there are many different strengths/thickness of aluminum.

I've seen iPad's dropped so many times the corners are caved in and it still operates as new.

While that may be true, what does that have to do with a galaxy phone? I specifically brought up iphones, and you change it to try to make your case. I will be more specific, I know of at least 20 iphone 4, 4s and 5 that have had busted screens, most of which were from falls from very short distances, and that is every person I know personally that has an iphone (15 people + 1 person that has lost 3 and one that has lost 2).

While I know of less people that have samsung phones, of those that do, only one has cracked her screen. I have dropped my phone so many times getting in and out of cars, at the gym, etc over the last 16 months, and it still looks like brand new.

I know that is anecdotal, but iphones are pretty notorious for breaking screens, and (with the 4) known to have reception issues without a case, which tells me that maybe aluminum is not the issue.

With the iPhone 3G/3Gs I criticized the polycarbonate back which would scratch easily.

So since apple used cheap, hard plastic that could not stand up to abuse, while others use softer, more flexible, more durable plastic, it must mean that all plastic is bad. Great logic there.

I've seen iPad's dropped so many times the corners are caved in and it still operates as new.

This is why metal is bad for mitigating falling damage. It has a rather stiff young's modulus (it doesn't deform much for a given stress). That means the deceleration forces from a fall are high, resulting in the metal quickly entering the permanent deformation region. And you end up with caved in corners.

With a more flexible material like plastic, the energy of the fall is dissipated over a greater distance/time, reducing deceleration forces, and thus reducing the likelihood of permanent damage. The plastic corner bends a lot more, possibly even resulting in the different major pieces of the phone snapping apart. But because the bending spreads out the forces and reduces the peak stresses, there's less chance of permanent deformation being done (other than a few scuff marks) and after the impact everything just snaps right back. Fighting styles like judo embrace this philosophy - minimize damage by redirecting the energy of blows instead of trying to resist them entirely.

HP (the old HP) understood this when designing their original Laserjet printers, the ones that weighed 50-75 lbs. People complained about the exterior being "cheap plastic". But the things could fall off a table, bounce around, and they'd continue to work perfectly fine. If it had been metal it would've deformed, the interior pieces would no longer be aligned, and it wouldn't function as a printer anymore. For the damage modes most frequently experienced by laser printers, "cheap plastic" was the superior exterior material choice. Heck, Apple understood the same thing when they made their laptop power plugs magnetic, instead of a long, rigid physical plug and socket.

No I'm not saying metal sucks. Materials all have a different roles based on their dozens of different properties, and it's the engineer's job to pick the material whose properties best suit the needs of the task at hand. If people were using their phones to support large weights or to hold things solidly in place or to provide puncture resistance, then yes I'd agree metal is the better choice than plastic. But for a device whose primary damage risk is falls from about 3-5 feet, you want a softer, flexible material on the exterior to take the brunt of the impact forces while the interior is protected by a stronger frame/chassis.

If the phone doesn't have that soft, flexible exterior, people feel compelled to buy one to protect the phone. That's why most iPad/iPhone owners buy a protective case. The metal is mostly decorative, not functional, so they feel it needs additional protection. I never really understood this - it's like buying a plastic wrap for your sofa to protect it from spills. If spills on the sofa are a concern, it should be designed from the beginning to be spill-resistant. And that's what the plastic back cover does. In essence the plastic back is your protective cover. And it's cheap and easily replaced if it gets too scuffed up for your tastes (a quick Google search says you can get them for the S3 for less than $10, probably less than $1 wholesale, making it cheaper than most protective cases).

Uhhh did you think about this when you said it? How are corners caving in some kind of testament to the quality of the materials?

Aluminum is great for some things. Absorbing impact damage, not so much.

The poly back to the iPhone 3GS was a mess. Have you any recently? It turns out that the whole back slowly warps, cracks, discolors and picks up scratches like nothing else I've seen.

iPhone 4 solved that with the glass backing. Of, it's glass...

iPhone 5 solved the issues with glass cracking by using aluminum but the black anodized layer wears off quickly on all edges and the buttons for volume control (the off switch rarely since who uses that?!).

Eventually they'll get it right...

Have you ever designed any products. Seriously?

Material selection is very important. Polymers are a valid choice for many products. Metal is not always the answer, nor is plastic or composite.

Saying your box of TicTacs is made of the exact same polycarbonate shows your complete lack of understanding (BTW, TicTac boxes aren't polycarbonate). What grade is being used? Percentage of regrind? Blend? Fillers? Textures? Overmolds? Coatings? I can go on.

Engineered plastics can be better (or worse) for a specific task. It's all about selecting the best performance. Price is also a consideration, but some plastic parts actually cost more than metal ones, depending on a lot of factors.

Just because you think plastic=cheap doesn't make it true.

Show me a phone with a user-replaceable battery that has back made of anything but plastic.

I would much faster trade a user replaceable battery with an aluminum case back any day of the week.

Might I point out who it is that is selling the most phones too (it ain't Apple).

Well with the iPhone 4S, you have to cover it with a rubber case in order to have it even work correctly. So the fact that it's pretty aluminum is moot.

By most people i do not think you mean most people. I think you talk from a personal experience and nothing more. To put it simply, i do not know of one single friend or colleague or associate who has a cover for their stupidly priced phone. Ok, i lie, my gf has one of these iphone 4 cases that doubles as a wallet/purse. So for me, 1 out of everyone i know in a non-stranger sense of the word, does not use a cover.

I have a Galaxy SIII and I'm fine with the plastic case. As the OP said, it's lighter than metal. Also, if you ever need to, you can cheaply replace the plastic back.

The main thing, though, is that I got a rubberized case for it as soon as I got it, so I almost never see the back of the phone. I don't really know why people make such a big deal about whether a phone is made of metal or not.

I have an iPhone 4S - the nice thing about the aluminum and glass backing is that the phone still looks brand new after 16 months. It looks like I've kept it in a drawer and never used it. So should be easy to resell. However it's pretty heavy, and I can't see using anything like this with a bigger screen. I think you really have to go plastic with something the size of the GS3 or Note II (which is the screen size I'm aiming fro for my next phone).

My lowly T-Mo MyTouch 4G still looks brand-new after the same period of use. And it's all plastic.

Ditto for my Galaxy S3. Still looks like new, because it's in a protective case. Even if the back of the phone was scrached, I could replace it with a brand new one from Amazon for $12. And here's the big thing: I can replace the battery with a new one any time I want.

I've seen many, many people walking around with iPhones with cracked screens. I'd worry more about that than about the back of the phone.

The S3 did much worse than the iPhone 5 in drop tests. Even Android Authority posted results where the iPhone 5 had barely a scratch while the GS3 was trashed.

The iPhone 4 was different since it had a glass back. Going to aluminum made it more durable than that design and the older plastic ones.

How would the drop tests look if the phones both had protective cases? Because that's really the sensible way to use your phone. Without a case, either phone is likely to suffer when dropped.

why can't EVERYONE understand the plastics used on the galaxy s3 actually make it a better phone. in addition to it feeling perfectly fine in the hand/pocket and plastics being able to better dissipate shock energy compared to solid aluminum frames when dropped, my favorite part of my s3 is that you can (literally) peal off the back plastic cover to replace the battery and/or sdxc card. it's so easy to do, it makes using a spare battery second nature. i can recharge my phone in a little under a minute by this method compared to being tied to a wall socket for hours on other phones.

a lot of people act as if replaceable batteries and expandable storage are just a gimmick feature for business and power users... but you are an idiot fishing for excuses if you think that's true. i'll never understand why people don't grasp this as an incredible advantage and perfect solution to the battery life shortcomings that afflict EVERY smartphone.
