The LG is the first smartphone maker to give us a properly curved screen smartphone so here’s our in-depth LG G Flex review.The G Flex is LG’s first curved screen smartphone and goes up against
local rival, the Samsung Galaxy Round. It’s got a bendy or flexible
screen which is fixed in a set curve. The device is now available and
although at most retailers you’ll have to pay close to Â£650 for the
luxury, Expansys has it, at the time of writing, for a more reasonable
Design and build
The main selling point of the G Flex is its curved screen so we’re going to be looking at this a lot.
While Samsung has gone for a side to side curve on the Galaxy round,
the G Flex does things in the opposite direction. It is curved from top
to bottom in a banana like shape. LG says, from a design point of view,
this is all about ergonomics.
It’s supposed to fit your face better when making a call and sit more
comfortably in your hand. In all honesty it doesn’t feel much different
than a regular flat smartphone in either of these scenarios. What we
can say, is that it fits much better in a back pocket.
Underachieving ergonomics aside, a bigger problem is the sheer size
of the G Flex. Yes, it matches the contour of my face better than a
‘normal’ smartphone but it knocks my glasses out of the way in order to
have a conversation. I could use it as a shade from the midday sun it’s
so big. I have very few items of clothing with pockets big enough for
the G Flex so I suspect female users will have to keep this device in a
LG has opted for a 6in screen for the putting it in that still new
and odd phablet category with devices like the HTC One Max, Nokia Lumia
1520 and Sony Xperia Z Ultra. It makes the fairly large LG G2 look quite
A big screen is great if you want to watch a lot of video content and
similar but in everyday use the G Flex is cumbersome and unwieldy. I,
with my relatively large hands, can reach a third of the display holding
it one-handed. In other words, be prepared for a tablet style
The back of the G Flex looks at lot like the G2 with LG’s Rear Key â€“
power and volume keys below the camera lens rather than on the side or
top of the device. I like this feature but it’s not for everyone. As
with the G2, you can switch the screen on and off with a double tap
which is the kind of feature which, once you’ve got used to, is shocking
to find doesn’t work on other devices.
On the rear of the G Flex is a self-healing cover which is supposed
to remove light scratches from things like coins in your pocket, not the
aggressive kind of scrapes from dropping the phone on hard ground or
similar escapades. It’s difficult to test this over a relatively short
period of time â€“ we’d like to take a photo of the back after months of
usage â€“ but after a few days there are a few hairline scratches on the
plastic surface. In the G Flex’s defence, these are only really
noticeable if you go actively looking for them.
LG G Flex review: Hardware and performance
We normally kick off the hardware section with the processor and some
performance but we’re going to go straight for the main event which is,
of course, that curved screen. We’ve talked about the size of the
screen a lot already so let’s look at what the panel is like itself.
Our first sample of the G Flex had some serious issues including a
horrible blue tint on about half of the screen and some distracting
image retention, or ‘ghosting’. So much so that we swapped it for
another handset and fortunately, things got a lot better. There’s no
blue tint and although there is some image retention, it only lasts a
split second rather than about five â€“ phew.
Something which didn’t go away is a grainy quality to the image which
doesn’t look particularly great. In some respects, it gives a softness
which some users might like but compared to other smartphones, it simply
It’s strange that LG has opted for a 720p resolution instead of Full
HD 1080p. On a screen this big, 6in, that makes for a not very
attractive pixel density â€“ just 245ppi to be precise. That’s not
something we want to see from a premium priced smartphone, no matter how
curved the screen is.
The curved nature of the G Flex is undoubtedly cool. I’ve shown off
the phone to various people with pride so it’s a great one for getting
out at the pub. However, this quickly wears off and over time we’ve
realised the benefits to the curved screen are minimal.
It’s supposed to be more immersive when watching a film or playing a
game in landscape mode – just like the curved TVs which are around now â€“
but we haven’t noticed a difference to a regular flat screen.
What it does do, is give a more dimensional feel when scrolling lists
or pages with the G Flex in portrait mode. While I personally quite
like this, I feel like it could make some users feel nauseous, similar
to but probably not as bad as the Nintendo 3DS with its glasses-free 3D.
Overall, with almost no real benefit to the curve, it seems that
Samsung and LG are fighting over the innovations because they can, not
because consumers need or want a smartphone with a curved screen.
Â This is an out of the box feature which you get only in this phone ! This self healing feature makes the LG G Flex the most interesting device in the world. it really heals its back from the scratches etc. soon i will write a whole article only for this self healing feature by the time read this article.
Like the G2, the G Flex has a Qualcomm Snapdragon 800 processor and a
2GB of RAM. After a 720p screen, it’s back to what we expect from a
top-end smartphone. Unsurprisingly, benchmark results are almost
identical to its smaller counterpart.
Geekbench 3 yielded a score of 2273, GFXBench 2.7 came in at 28fps
and we got a time of 1103ms in SunSpider. That’s almost up there with
the impressive HTC One M8 but not quite.
With almost every smartphone manufacturer boosting performance for
benchmark apps (admittedly or not), we’re much less bothered about
numbers. From a real-world user perspective, the G Flex offers decent
performance. That Snapdragon 800 has proven to be a formidable force and
is very capable of dealing with most requests.
There’s only one model of the G Flex and it has 32GB of internal
storage. That’s a decent amount considering most phones in this price
range have half that. However, the device does not have a microSD card
slot which is a shame. It’s not like there isn’t room for one with a
device this large.
Infrared and wireless
As with the G2, the G Flex has an infrared transmitter for taking
control of devices like your TV. There’s a Quick Remote section of the
notification bar which you can toggle on and off so you don’t even need
to launch the app to change channels or adjust volume. You’ll need to
hold the phone upright for it to work properly though since the sensor
is located on the back, next to the camera rather than on top like a
As for other wireless, you get pretty much what you’d want from a
top-end device. There’s Bluetooth 4.0 Low Energy, dual-band Wi-Fi up to
11ac, NFC, GPS and support for 4G LTE networks.
What we’re still not seeing is wireless charging. It seems that only
top-range Nokia and Google Nexus devices have this feature as standard.
