LG G Flex is the world’s first curved and flexible smartphone. Though you might have seen curved phones from other companies but this one has a flexible body which makes it different from other curved devices. LG G Flex seems to be the answer to the question being asked by most of the people these days -“In the Smartphone War what’s next?”. So does LG G Flex really an innovative device? Is it the future of smartphone? Read on to find out.


Design & Build Quality

LG G Flex is curved vertically rather than horizontally like in Galaxy round. Vertical curve looks more natural and helps in improving the call clarity by bringing the microphone close to your mouth. The body of the device is curved with a 700mm radius and if you press the device on a flat surface it can go flat and then regain its shape.


The front of the device is dominated by 6 inch HD display and the device has narrow bezels.

In terms of build quality and design we are really impressed with the device. Things like curved display, flexible body and self healing back make it stand out from the crowd.


LG G Flex comes with a 6 inch HD P-OLED display which is covered with a thin sheet of glass. The display has good viewing angles and brightness level. The outdoor/sunlight visibility is decent. It is not the best we have seen in a 720p display.

Hardware & Performance

The phone is powered by a 2.3 GHz Qualcomm Snapdragon 800 processor along with Adreno 330 GPU. It comes with 32GB internal storage and 2GB of RAM. The powerful specs enable the device to run any game or app with ease. You won’t face any kind of lag when it comes to UI, daily apps or high end games.

To show the performance of the device we played few high end games on it such as Asphalt 8 and Modern Combat 4. You can check the gaming test below:

As you can see in the above video the device is quite powerful and it can handle all the high end games easily. You won’t get disappointed with the device if you want to have a smooth and super fast experience.


LG G Flex runs on Android 4.2.2 Jelly Bean OS along with Optimus UI on top of it.  The software part is similar to previous LG devices like G2 or Optimus G Pro. It comes with some interesting features like Q Slide, Knock on, Slide Aside and Multi window.

The knock on feature allows you to wake up the device or put it to sleep by simply double tapping on the screen. Slide Aside allows the user to switch between multiple apps by a simple 3 finger swipe gesture across the screen.

The device has a feature called as one handed operation which allows the users to operate the device with just one hand. Another handy feature present in the device is the ability to hide touch buttons. You can select the apps in which you want to hide the touch buttons.


The device comes with a 13 megapixel back camera with LED flash and a 2.1 megapixel front facing camera for video calling and for taking selfies. The camera UI is similar to the one we have seen in LG G2.

LG G Flex cameraThe camera offers various modes like Panorama, VR Panorama, Beauty Shot, Time Catch Shot etc. It supports 4K video recording at 30 fps and Full HD video recording at 60fps. Here are some sample images captured using the back camera of LG G Flex:

Overall quality of the captured images is quite decent but the video performance is really good.

Battery life

The device comes with a 3,500 mAh battery which provides it an amazing battery life. The phone can easily last for a day even with heavy usage. In our test we played games on the device for around 2 hours, watched videos for 2 hours, made few calls and 3G was on for the entire day. Still at the end of day there was around 1/4th battery left in the device. LG G Flex is undoubtedly one of the best smartphone available in the market in terms of battery life.


LG G Flex is available in India for Rs 68,000 which makes it one of the most expensive smartphones in the market. Company has given lots of innovative features in the device such as curved display, flexible body, self healing back etc which justifies the price of the device. So if you want to own a device which is currently more advance than any other phone available in the market you can opt for it.
