LG G Flex: Screen Quality

Andrew Williams

By Andrew Williams



Our Score:


The LG G Flex may have a giant screen that is one of the most notable we’ve seen in a while, but that doesn’t mean it is any good in terms of pure image quality. It has significant issues.

It is unable to properly display block colours, and is riddled with what looks like moire noise throughout the entire display. It’s weirdly mottled unless it’s displaying pure black. You can trick yourself it’s a deliberate effect of the G Flex’s background and icons until you head somewhere like the web browser, where the unsightly texture of the phone’s screen is undeniable.

The only way to minimise the effect is to turn brightness up to maximum. Of course, that will also minimise battery life so isn’t much of a solution.

The G Flex also has serious issues with image retention. High-contrast objects like the clock or any particularly bold app icons are visible for 20 seconds or so after they should have left, in the form of ghostly afterimages. And, once again the effect is much worse when brightness is set to the lower levels most of us use, rather than max.

It’s been so long that we’ve seen such basic screen issues in a mobile device that we at first thought they were some sort of ill-advised software feature. But they are not.

These problems are the sorts of gremlins you get when working with a fairly young screen technology. P-OLED’s problems will be ironed out in time, but it's already too late for the LG G Flex.

Colour reproduction is reasonable at top brightness, but colour fidelity is decimated as soon as you turn the brightness down a bit thanks to the screen texturing issue. LG G Flex 18

As you’d hope from an OLED screen, contrast and black level are both very strong. You don’t get the residual luminance of an LCD screen’s backlight here, so in a darkened room blacks remain super-black. The G Flex’s screen bezel is slightly silvery too, making the display actually look blacker than the surround.

There is yet another issue with the screen, though – resolution. The G Flex has a 720p resolution display, which is not much to work with across a 6-inch screen. Pixel density is 245ppi. And it’s not enough to make text look super-sharp.

Turn up the brightness to get rid of the screen texturing issue and sharpness is reasonable, but not for a £500 phone. Clarity is much worse than many cheaper rivals, including LG’s own LG G2, which has an excellent display in comparison. We can once again blame that P-OLED is still in its early stages, but that isn’t something the phone buyer should have to put up with.

It's all well and good having a curved screen, but not if we have to go back to plastic screen coverings like the ones we used to have with the old resistive technology. It took ages to move to glass, and then a good glass that won't scratch easily. Plastic scratches far too easily, so unless we're going to see Gorilla making curved glass to fit these soon (thus removing all the flexibility you like) I know I won't be having one.

"the world's first curved battery" - I know what you mean, but I think I'd describe a regular AA battery as curved given that it's a cylinder. However, Apple may have something to say about this claim also as they patented the curved battery back in the summer... http://www.trustedreviews.c...

Is a curved screen what people really want?

From the specs alone, it would seem that this is of inferior quality to current glass based screens.

What I would really like is for manufacturers is to focus on practical things liks a battery that lasts a week and takes minutes to fully charge or a phone that is robust enough for daily use but doesn't need screen protectors and bulky cases.

this will go the same way as the "chin" did.

I suggest you actually read the article before posting comments like this. If you look at page 3, you'll clearly see that it does have Gorilla Glass. Corning have already made Gorilla Glass flexible enough to work on this phone.

I bent one in the shop today and it made a terrifying creaking sound, it seemed like it was breaking. Seemed quite pointless

you obviously didn't read the full article, as they state quite clearly that the phone DOES use Gorilla Glass, and it IS flexible. Make sure of your facts before you write smack dolt...

Just bought two LG G Flex phones. One of the units has a defective front facing camera that causes the error "Cannot connect to camera" to be thrown when selecting camera switch icon. The only way to recover the rear camera function is to Factory Reset. (tried all other options force stop camera app, restart unit,...). Even after Factory Reset front camera does not work and throws error (requiring Factory Reset again).

Iv had my G Flex since the end of this last summer 2014 and I absolutely love the thing!!! I have always personally favored and leaned toward the brand LG my reasoning being that of I have absolutely NEVER had any sort of kind of ANYsuch issue, no kind of problem absolutly nothing has ever occured with anything I have owned or even used of the brand LG! I have had accidentally drops or have had it slipped out of my hands or off a piece of furniture, it has landed on the screen on various surfaces such as pavement, cement, gravel (large & small & pee sized), sand, grass, carpet ect! I have yet had a scratch appear on my screen thank the lord, I try to keep it as safe as I possibly can so that nothing to horrendous does come about and happen cause forking out a hefty $200 or so deposit is insane, and not being guaranteed a brand new phone even having to pay that much is just flat out insanely ridiculous! If you pay for coverage and still have to pay a deductible of $200 you should absolutly be guaranteed a new phone not a phone that has been refurbished, cause no sooner than not there is going to be issues if not already have one two or 150! But yes my G Flex has absolutely been amazing I have had NO issues or problems my bettery has worked and still works amazingly and last depending how much I use my phone but can last up to 1.5-2 days, the shortest amount of time has been about 3-4 hours because of me using it non stop!
I hope people who have gotten it or that are thinking about getting it enjoy it and at least give it a.try cause it is a lot of fun and does wonders!! The video is absolutwly awesome as well I watch shows movies and recordings all the time and pictures are even more fun ont his thing I am in love with the thing!!! I wouldnt mind trying out the
LG G3 for my next phone or if somethng else cokes out along this line I would defintly not hold back!!!
