LG G Flex: The Curved 6-Inch Phone with a Self-Healing Back

The LG G Flex was one of the boldest smartphones of its era. Released when most phones still followed the familiar flat glass-and-metal formula, it introduced a gently curved body, a flexible 6-inch display and a rear cover designed to repair minor scratches. It looked like a concept device, yet it was sold as a fully usable Android handset.

Its curved profile ran from the top of the phone to the bottom, following the shape of a face rather than bending from side to side. LG said the design could sit comfortably against the user’s head during calls, while the flexible construction helped the handset survive pressure that might damage a rigid phone.

The defining feature was the “self-healing” rear panel. Small marks from keys, coins or everyday handling could fade over time, especially in warm conditions. This was a clever piece of materials engineering, although it did not make the G Flex immune to deep scratches, dents or careless treatment.

For Australian buyers, the handset arrived as a premium curiosity at a time when large-screen Android phones were gaining popularity. It appealed to people in Sydney, Melbourne and Brisbane who wanted something more distinctive than another black slab, while its size and launch price placed it well above ordinary budget phones.

A Screen Built Around The Curve

The LG G Flex used a 6-inch Plastic OLED display with a 1280 × 720 resolution. By current standards, that pixel count is modest for such a large panel, but the screen still delivered strong contrast, deep blacks and vivid colours. OLED technology also allowed LG to build a thinner and more flexible display than a conventional glass LCD panel.

The vertical curve was subtle rather than dramatic. It did not fold, roll or transform in the modern sense; instead, the whole handset bowed gently from top to bottom. When placed face down on a desk, the phone could rock slightly, which made the design memorable but also made the device feel less familiar than a standard smartphone.

The curve had practical advantages during calls. The top and bottom edges sat closer to the user’s face, and the shape gave the phone a distinctive grip. Watching video could also feel more immersive because the display wrapped slightly into the viewer’s field of vision. Still, the 6-inch diagonal made one-handed use difficult for many people.

The display resolution was the main compromise. Text and icons were clear enough for messaging, web browsing and Google Maps, yet small fonts did not look as crisp as they did on the full-HD panels appearing on competing flagship phones. Buyers interested in reading on the train between Parramatta and central Sydney would notice the difference more than someone mainly watching videos.

The Self-Healing Rear Cover

LG’s self-healing technology was applied to the phone’s soft, flexible rear coating. Fine surface marks could gradually disappear after the material warmed and relaxed. The effect was most convincing with light scratches caused by ordinary pocket use, rather than damage that cut through the finish.

The feature was especially useful because the G Flex had a curved back that was difficult to protect with a conventional hard case. A typical cover could hide the unusual design, while a loose pocket with coins or keys could leave marks on a normal phone. The resilient coating gave owners some reassurance during daily travel.

There were clear limits. Deep gouges, chips, dents and damage to the screen could not repair themselves. The process was also not instant, and results depended on the depth of the mark and the surrounding temperature. It was a useful protective layer, not a replacement for sensible handling or a screen protector.

The rear also housed LG’s unusual control layout. Power and volume buttons were positioned below the camera, a design that LG called Rear Key. It suited the curved shape and made the controls easy to find while holding the phone, though users moving from a Samsung, Apple or older BlackBerry handset needed time to adjust.

Flagship Power From The Android Era

Inside, the G Flex was powered by Qualcomm’s Snapdragon 800 processor with four 2.26GHz Krait cores and 2GB of RAM. That combination made it a fast phone in 2013 and early 2014. Apps opened quickly, games ran smoothly and the interface felt responsive even when the large display was handling several tasks.

The phone shipped with Android 4.2.2 Jelly Bean and LG’s Optimus user interface. Its software included features such as QSlide for running supported apps in floating windows, KnockOn for waking the display with a double tap and a split-screen approach aimed at making the large panel more useful.

The 13-megapixel rear camera produced respectable daylight photographs, while the 2.1-megapixel front camera handled video calls and basic self-portraits. Camera performance was not the handset’s main selling point, though. Samsung’s Galaxy Note range and Apple’s iPhone 5s generally attracted more attention from buyers who ranked photography above experimental design.

A 3500mAh battery was one of the G Flex’s strongest practical features. The curved phone had room for a large cell, and many owners could expect a full day of regular calls, browsing, music and video. Heavy 4G use, GPS navigation and bright-screen gaming could still drain it faster, particularly during long commutes or hot Australian summer days.

Living With It In Australia

The G Flex made sense for Australian users who valued battery life and a generous screen. A long trip across Melbourne’s suburbs, a train ride from the Gold Coast into Brisbane or a day relying on maps in Perth all benefited from the large battery and fast Snapdragon processor. Its 4G support also suited the expanding high-speed networks offered by Australian carriers.

Carrier availability and pricing mattered more than the novelty. At launch, the phone sat in the premium category, with Australian pricing commonly discussed around the A$800 mark depending on retailer and plan. Telstra, Optus and Vodafone customers could encounter different outright prices, contract terms and network-band support, so checking the exact model was important before purchase.

The handset’s size was less convenient in a country where people often carry phones in jeans pockets, small handbags or work trousers. It measured roughly 160mm tall and weighed about 177 grams. That was manageable for a 6-inch phone, but it remained far larger than compact models such as the iPhone 5s or many mid-range Android devices.

Australian buyers also had to consider GST, local warranty coverage and replacement parts. A grey-import G Flex might appear cheaper than an Australian retail unit, yet warranty service could be limited and mobile-band compatibility was not guaranteed. During sales periods such as Boxing Day, an official local model could offer better value even if its ticket price was slightly higher.

Is The G Flex Still Worth Remembering?

The LG G Flex was never designed to be the safest choice for every buyer. Its display resolution lagged behind some rivals, the curved shape made cases and pockets awkward, and the self-healing back could create unrealistic expectations. It also lacked the long software support that modern smartphone shoppers now expect.

Its importance came from experimentation. LG used flexible OLED technology, a curved battery, rear-mounted controls and a resilient coating in one commercial device. The phone showed that a manufacturer could challenge the standard rectangular design without producing a fragile prototype. It also anticipated later interest in flexible screens and bendable materials.

For anyone comparing it with other phones from the same period, the strengths and compromises become easier to see:

Standout feature	Curved body and self-healing back	S Pen and productivity tools	Compact design and Touch ID
Best suited to	Large-screen early adopters	Note-taking and power users	People wanting a smaller premium phone

The G Flex is best understood as an early experiment that happened to be usable as a daily driver. Its processor, battery and OLED contrast remain respectable for its generation, while the unusual body still attracts attention. People who enjoy revisiting distinctive devices will find it more interesting than a conventional 2013 flagship.

Those researching older handsets can also explore broader LG phone reviews to compare the G Flex with the company’s flatter G2 and later models. That comparison highlights how quickly LG moved from familiar flagship hardware to more adventurous designs, then gradually returned to more conventional shapes.

For collectors, retro Android fans and technology readers interested in the history of flexible displays, the LG G Flex remains a memorable choice. Its self-healing back was limited but genuine, its curved 6-inch screen was ahead of its time, and its Australian launch demonstrated that unusual smartphone design could reach ordinary retail shelves. Explore the specifications, check local network compatibility and compare current second-hand prices before adding this distinctive handset to your collection.
