A powerful, feature-packed handset with a brilliantly attractive design. Sadly the screen seems to have suffered as a result.

The G Flex is what I wish the G2 had been. It flouts convention in a way the LG phones of old did, but it doesn't go so far afield that it forgets how to be a great smartphone - because it is a great smartphone.

Mobile Syrup | Daniel Bader

The G Flex is a successful experiment from a company that likely never expected it to expand far beyond its Korean borders. While it's hard to recommend on the hardware differentiation alone - the curve is interesting but not that useful - the device is a great all-round performer.

The G Flex represents a huge innovative step forward for LG. The company has managed to give curved-screen technology validity in the smartphone form factor, and in Australia they managed to do it first. But they didn't stop there: it has a leading battery, a 'self-healing' back and the ability to record videos in UHD resolution. These are all great reasons to go out and buy this smartphone.

As a normal phone the G Flex 2 would be great, but adding a near-indestructable build quality makes it truly outstanding.

Android Authority | Joshua Vergara

Besides the style factor – and, arguably, the improved endurance – the curved screen does not change user experience in a substantial way. The G Flex is not worth buying for its curved screen alone, but it's definitely an interesting device that you should at least consider if you're shopping for a cutting edge Android phone.

It doesn't feel too bulky, despite its size, and the battery life has me (quite literally) coming back for more. I've adjusted to the lower-resolution screen, and I'm really not complaining too much about the plastic artifacts I see when I look close. While I do still feel a bit nauseous using it to read news and while browsing Twitter, my eyes aren't as sensitive as they were on the first day of use. I'm definitely going to tweak some of the software so that Google Now is front and center, and I do wish the camera had OIS, but it otherwise meets all of my needs.

SlashGear | Chris Burns

While we're not entirely convinced this device really needs a curve, the rest of the device is fine enough to be worth the cash it costs.

Digital Trends | Jeffrey Van Camp

Thanks to its curved design, the LG G Flex is the first six-inch phone that we want to hold. It also has a better battery (two to three days) and more processing power than any phone out there.

The G Flex is basically the G2 on steroids and protein shakes. To say it is almost as big as a small newborn born, or felt like it, wouldn't be totally off the mark. The phone is a whopper.

ITProPortal | Sandra Vogel

The LG G Flex seems to be a lot more about showing off what can be done, rather than actually producing a compelling handset that lots of people will want to buy. If you like the way LG tweaks Android and the design feature of having volume and power buttons on the back, then take a look at the LG G2, which has a higher screen resolution and a lower price.

What Hi-Fi?

If you can let the lower-res screen slide, this is ultimately all that's great about the G2 in a larger form and with a distinctive, head-turning design. For those that want to stay ahead of the curve, the LG G Flex is certainly worth considering.

LAPTOP | Dan Howley

LG's flexible, self-healing G Flex is an innovative and fast handset that feels like the future of smartphones.

MSN Tech | Ian Morris

What could just be silly gimmickry actually has some serious advantages. A curved screen is something you might not have thought you needed, but it's comfortable to use as a phone and offers loads of features that we really liked. The battery life is great, the screen is very usable and there's enough power here to keep you happy. The biggest problems seem to be the price, and the slightly sluggish feel the phone gives compared to the G2.

What Mobile | Jamie Feltham

We can't blame LG for trying something different but this isn't an essential innovation.

Stuff | Nigel Yap

There's a lot about the G Flex that's brilliant, from the searing performance to the massive battery life and unusual, bottom-hugging styling. But that only makes the disappointments even more frustrating.

Phone Scoop | Eric M. Zeman

First you absolutely *have* to be a phablet fan. Second, you have to be willing to take a chance on the G Flex's odd shape. Third, you have to not mind the G Flex's price tag. There are other, similar-performing phones out there for less money, but none will spark as much conversation as the G Flex.

The Boxed (UK) | Editorial Team

he bendy curve - which, to be honest, we first thought was just some sort of gimmick - does make the rather huge phone easier to handle and the killer battery life is all we could ever ask for. The G Flex is also fast, maybe even the fastest available at the moment, and the new interface makes it easy for everyday use.

Digital Spy | Mark Langshaw

...you have to ask yourself whether you're happy paying extra for what will essentially be small benefits where most users are concerned.

PC Advisor | Chris Martin

The LG G Flex has some decent hardware including a great camera and more storage than usual. Excellent software is also a lure but its main feature, the curved screen, is too big, only 720p and offers no real benefits.

NDTV Gadgets | Ershad Kaleebullah

Yes, it has a curved screen. Yes, watching videos is a great experience on the G Flex. Yes, the performance is top-notch. Yes, it has a great battery life. Yes, it has no competitor in its niche in the market at the moment. But for most people, this still isn't enough to justify spending so much money.

The Verge | David Pierce

For all it is and claims to be, there's nothing practically compelling about the curved screen. The self-healing coating is interesting but limited, as much psychological comfort as actual solution.

The Mobile Indian | Samir Makwana

The G Flex does pack a powerful hardware and large battery to make it run for long time. But it is difficult to convince anyone for slide and walk with a large curved phone in the pocket.

Gadgets Now

G Flex is an amazing piece of engineering ... however, we feel it's still not ready for prime time as LG is not able to offer any significant use case for it.

Brighthand | Dragan Petric

Even with its odd appearance, the LG G Flex brings its highly up-to-date chipset to the phablet, which ensures supreme performance. True to its name, the LG G Flex is flexible. Too bad that's not enough to overcome this Android phablet's glaring shortcomings.

Digital Versus | Romain Thuret

The G Flex is supposed to be a sort of crowning jewel for LG, a product symbolic of the future of mobile devices. But to buy a G Flex today is to invest in a promising niche, rather than enjoy a perfected new technology.

Trusted Reviews | Andrew Williams

As a demo of new technologies it's interesting. However, as a phone you'll have to pay more than £500 for, it's a no-go.
