The LG G Flex 2 was a weird phone. Honestly, it was glorious in its weirdness. Back in 2015, while every other manufacturer was busy making flat glass rectangles, LG decided to build a smartphone that looked like it had been left on a car dashboard in the middle of a July heatwave. It was curved. It was flexible. It even "healed" itself from scratches.
But it was also a disaster in some very specific, very frustrating ways.
If you remember the hype around the LG G Flex 2, you probably remember the gorgeous Flamenco Red finish and that futuristic P-OLED display. It felt like the future. Fast forward to now, and we’re seeing foldable screens everywhere, but the G Flex 2 was the pioneer that took the first real risk with "bendy" tech. It’s the bridge between the old-school bricks and the modern Galaxy Z Folds of today.
The Curve: More Than Just a Gimmick?
Most people thought the curve was just for show. LG claimed it was "ergonomic." They said it fit the contour of your face better during calls. That part was actually true; it felt great against your cheek. It also supposedly brought the microphone closer to your mouth, which was a nice touch, though nobody really complained about mic distance on flat phones anyway.
The real magic was the flexibility. You could literally place the LG G Flex 2 face down on a table and press it flat. It wouldn’t snap. It would just... bend. And then pop back into its curved shape. This wasn't just a party trick; it made the phone incredibly durable. If you sat on it while it was in your back pocket, it didn't crunch like an iPhone 6 Plus (the infamous "Bendgate" era). It just went with the flow.
That Weird Self-Healing Back
One of the wildest things about the LG G Flex 2 was the back cover. LG coated it in a special "self-healing" polymer. If you scratched it with your keys or some loose change, the scratches would literally disappear within about 10 seconds.
It felt like sorcery.
Well, okay, it worked for hairline scratches. If you took a knife to it, you’d have a permanent scar. But for the daily wear and tear of being tossed onto a desk, it was brilliant. The updated version on the G Flex 2 was way faster than the original model, which took minutes to heal. This one was nearly instant.
The Snapdragon 810 Nightmare
We have to talk about the elephant in the room: the processor. The LG G Flex 2 was the first major phone to ship with the Qualcomm Snapdragon 810. On paper, it was a beast—64-bit, octa-core, the absolute pinnacle of mobile power.
In reality? It was a furnace.
The 810 was notorious for overheating. Because the G Flex 2 was so thin and made of plastic, it had nowhere to dump that heat. After ten minutes of gaming or even just heavy browsing, the phone would get uncomfortably warm. Then, the "throttling" would start. To keep from melting itself, the CPU would drastically slow down.
Suddenly, your high-end flagship felt like a budget phone from three years prior. It was a massive letdown for power users who spent a premium on what was supposed to be the fastest phone on the market.
Display Wins and Losses
LG swapped the giant 6-inch 720p screen from the first Flex for a much more sensible 5.5-inch 1080p P-OLED panel. This was a huge upgrade. The pixel density jumped to 403 ppi, meaning things actually looked sharp.
- The Good: The blacks were inky and perfect, as you'd expect from OLED.
- The Bad: At low brightness, the screen looked... grainy. Like someone had sprinkled fine sand over the glass.
It was a common issue with early P-OLED tech. If you were reading an ebook in bed at 10% brightness, the "mura effect" (that uneven, cloudy look) was impossible to ignore. Still, for watching movies, that subtle curve did actually make the experience feel slightly more immersive.
Why We Should Still Care About the LG G Flex 2
LG isn't in the phone business anymore, which is a genuine shame. They were the only ones willing to be truly experimental. The LG G Flex 2 wasn't a perfect product, but it pushed the industry to think about materials. It taught us that "plastic" doesn't have to mean "cheap"—it can mean "flexible" and "durable."
Without the failures and experiments of the G Flex series, we might not have the sophisticated hinge mechanisms and ultra-thin glass we see in today's foldables. It was a necessary stepping stone. It was a brave, flawed, beautiful piece of hardware that dared to be different in an increasingly boring market.
Actionable Takeaways for Tech Enthusiasts
If you're looking back at the G Flex 2 or considering how it fits into the history of tech, here are a few things to keep in mind:

- Innovation requires sacrifice. The G Flex 2 sacrificed thermal stability for a radical form factor. When buying new tech today, always check if the "cool feature" (like a first-gen folding screen) is coming at the expense of basic functionality like battery life or heat management.
- Respect the "Proof of Concept." Some gadgets aren't meant to sell 50 million units; they're meant to prove a point. LG proved that curved displays were possible and durable.
- Check for "Thermal Throttling." Even in 2026, many high-end phones struggle with heat. Always look for independent "stress tests" in reviews rather than just looking at the raw chip specs.
The LG G Flex 2 remains a legendary "what if" in the world of mobile technology. It was a phone that refused to play it safe, and even though it eventually succumbed to the heat of its own ambition, it's still one of the most interesting devices ever made.
