LG has made a name for itself with innovative designs and unique handsets in recent years. One look at the LG G Flex 2 and its easy to see what they hope will make it stand out. As one of only a few flexible, curved smartphones on the market, it is certainly eye catching, but does it perform as good as it looks? Let’s see what the reviews think!

The biggest selling point on the phone is its curved design. Stuff spent some time handling the device and found it “feels very comfortable and natural in the hands.” If you’re hoping for a phone that you can bend to extreme angles, the technology isn’t quite there yet. Most reviews noted that even curving the phone enough to flatten it took considerable force.

However, all agreed that the design of the phone was excellent, with Trusted Reviews stating that it “wears its plastic build in a particularly high-end fashion.” The phone also features a self-healing rear coating that LG claims will repair minor scuffs and scratches in 10 seconds. PC Advisor took a wire brush to the cover and found its repair abilities “impressive.”

The heart of the phone is a 2GHz Octa-core Snapdragon 810 with 2 or 3GB of RAM depending on your specific model. All reviews noted how snappy the phone was. As one of the first phones to sport this new chipset, it is likely to remain a powerhouse for the next generation of handsets released as well. PC Advisor called performance “smooth” while Trusted Reviews noted “no lag or stuttering in the handset’s performance.”

Gracing the front of the phone, you’ll find a 5.5-inch 1080p P-OLED display. The flexible display earned respectable reviews. Trusted Reviews stated, “Colours were vibrant and full of pop, while blacks were impeccably dark.” However, with the rise in Quad HD devices, the resolution is far from the highest available. PC Advisor pointed out that visuals and text were “nice and crisp although a little ways behind Quad HD.”

If you’re looking for a portable way to enjoy your movies and tv shows or like to try out tons of apps, you’ll find the 16 or 32GB of internal storage offers plenty of room. The phone also supports microSD cards, with LG stating the phone will accept cards up to 2TB in capacity when the technology arrives.

Will all the power under the hood, the phone needs a beefy battery. While non-removeable, reviews indicate that the 3000mAh battery, combined with the efficiency of the P-OLED display should provide respectable all-day battery life.

One area where reviews were mixed was the G Flex 2’s camera. While a 13MP camera with optical image stabilization and dual flash sounds good on paper. Numerous reviews noted a lack of detail and light balancing issues in photos. However, all touted how quick the camera performed and loved the gesture-based selfie mode. Stuff was the most positive, claiming, “shots appear to be sharp and detailed.”

Overall, the LG Flex 2 combines solid specs with a unique design that will hopefully secure its place in the rankings on the next round of flagship devices. Trusted Reviews called it “an undoubted step up from its predecessor in every aspect.”

What the Critics Are Saying...


The LG G Flex2 is not a great smartphone, especially at such a high price point. What it really is, is an engineering marvel. It’s a huge accomplishment for LG, they have product with no substitute. And, it’s highly likely that if you’re interested in the G Flex2 in the first place...

It's good to see LG have another pop at the curved phone and on the whole we're impressed with the G Flex 2 and since it's been around for a while the price is something of a bargain. The curve is by no means necessary but it does feel and look good and improvements include the higher screen resolut...

The G Flex 2 overall was a great phone to use. Actions were quick, apps loaded up smoothly, and I never noticed any lag. Probably the only thing I noticed was that the phone was able to get pretty hot when playing a game, or doing a lot of multi-tasking. This is likely due to the fact that it uses a...

LG's attempts to create a viable curved smartphone for the masses seem to be thwarted by nagging issues - this time it is the performance of the processor. It is not something users can't live without but considering the phone costs north of Rs. 50,000, such minor shortcomings are unforgivable.Inter...

- Ershad Kaleebullah, NDTV

The positives of this handset is that it stood out and the curvature of the device was pretty much spot on. As the old Goldilocks story goes, it wasn’t too much, wasn’t too little – juuuuuust right. It was speedy too, but I struggled to see why (other than the fact it’s curve...
