LG G Flex drop test: does flexible mean unbreakable?

LG G Flex drop test: does flexible mean unbreakable?
In general, a drop test is a drop test. No matter the materials used these days, glass is still glass, and given the right type of impact, glass always breaks. But, we've long been hearing about these fabled "unbreakable" flexible displays that would be hitting the market. The first is in the LG G Flex, and the guys over at Android Authority have put the device through a drop test.

So, does flexible mean unbreakable? In short, no. At least not the glass on top of the display. The screen still worked after all of the damage, so the flexible display underneath may be "unbreakable", although plenty of other devices still work with cracked glass. The LG G Flex can stand up well to flexing and bending, which would crack even traditional glass; but, the flexible glass couldn't protect against impact with the ground. Similarly, the highly touted "self-healing" back of the device has its own limitations. As we've seen before in testing, the back will heal from scuffs and even mostly heal from a knife cut, but deeper gouges from being dropped will not fully heal. 

One thing that was pretty amazing in the drop test was just how high the G Flex bounced when dropped on its side. It seems that the combination of the curve and the flexible glass acted somewhat like a spring when the device was dropped on its side. Of course, it still didn't protect it from a cracked display. In the end though, while the glass did crack, the device was still usable, so that's a good sign.

I can remember Samsung flexible screen is almost a month older than LG G flex, I'm expecting to see the Samsung flexible screen drop test. Nonetheless, still expect phonearena to update us for that of Samsung flexible screen.

Samsung's phone, Galaxy Round was released in limited numbers if I'm not mistaken. I'm guessing that people who bought it wouldn't drop it due to the limited production.

Samsung didn't make Round's screen flexible, it's simply just round, only Flex is actually a bit flexible. You can watch their reviews. Btw, the Flex broke dropped, but it at least can stand sitting on it, or the pressure of heavy things put on it. Other phones are not that good at it.

I was hoping flexible screens means unbreakable screens but I guess that want the case.

The screen is unbreakable. But the glass covering it isn't

this is what i always had doubt! whether the glass covering the scree n is unbreakable or is that only the screen is unbreakable?

Samsungs working on non glass display covers made of plastic that are much more durable. No idea if LG is.

Whatever Samsung's doing, LG must be doing as well.

Plastic will be stretched a lot more, it is more durable but it is not as hard you will stretched it a lot more.

Like in that vid where someone in a lab puts normal glass substrate and the plastic substrate screens on a table and hits them with a hammer. And keeps hitting them so many times that it gets boring. And in the end there's just some powder left of the normal one while the plastic continues working just fine.

There is no such thing as "unbreakable", just harder to break. However flexible it may be, the screen and glass are still fixed which greatly reduces its ability to flex out and disperse the kinetic energy on impact. Until the phone itself can flex freely like one of those old snap bracelets, its still going to be easy to crack... just less easy.

The benefits of flexible screens is that when you drop them, you might only end up breaking the glass. The digitizer won't break and you'll end up saving a couple of hundreds of dollars.

I'm afraid the digitizer is in the glass cover while it's the screen that is behind it. So you break the cheap digitizer and save the expensive screen.

Like I always say it needs plastic or sapphire glass

that's only if they're made of plastic

Screen failed miserably. Self-healing back failed miserably. It seems obvious to me now that this phone is a gimmick & curved screens in this regard have no advantage over flat ones.

tell me about an unbreakable phone, please; so i can go an buy it.

18. g2a5b0e unregistered

I don't see what that has to do with anything I just said. Clearly, there are no unbreakable phones available on the market as of this time. My point was that if this phone fared worse than most phones do in these type of tests, simply curving the screen is probably not the way to go in achieving that end. Obviously, a lot more R&D is needed in figuring out what will make for a truly unbreakable phone.

A sapphire glass screen or plastic screen that's what they need

You missed his point in that you writing off any attempt to produce even a slight advantage in that department via any innovation. No it isn't perfect, but these drop tests are far from perfect. Everything depends on the phone landing one way or another. Your tirade against it and calling all attempted achievements a gimmick are what he went against and the community seems to acknowledge that. God forbid we in the Android crowd get stuck with real innovation like 64 bit and panorama mode 3 years after its made.

There's no point in flexible screen if the glass breaks anyway.

What was that supposed to mean? I think a more convenient option would be buying a case or just simply take good care of it...
