We’ve decided to compare two awesome flagships which are housing the same chipset and have a 5.5-inch screen with a Full HD resolution. But each company has perfected its design style and these phones have a unique appearance. Moreover, both the G Flex 2 and OnePlus 2 are successors and trying to live up to the first models’ level.

Designs and Displays

As we were saying, both phablets have 5.5-inch screens which support a resolution of 1080 x 1920 pixels, but LG is using a Curved P-OLED capacitive touchscreen which offers a slightly higher pixel density of 402ppi, and as its name suggests, it can bend and the faint curvature goes from a 400 to a 700mm radius. Compared to the first model, the Flex2 is more durable and after its frame is straightened out, immediately it flexes back into its original arch shape. In addition, it features a self-healing back which recovers from light scratches in 10 seconds. The device measures 149.1 x 75.3 x 7.1-9.4 mm and it weights 152 grams.

The OnePlus 2 inherited its predecessor’s design, but the body has now a rectangular shape (the original phone came with a floating arc design) and it features a metal frame, which makes the device 1mm thicker. The successor measures 151.8 x 74.9 x 9.9 mm but it’s 23 grams heavier than the Flex2, although the screen has the same size. However, the technology is LTPS LCD, which gives a pixel density of 401ppi.


Although both phones are housing a 64bit Qualcomm MSM8994 Snapdragon 810 octa core processor, the Flex2 has two cores running at 1.5GHz and two cores are clocked at 2GHz, while the OnePlus 2 has set the clock speed of four of the cores at 1.56GHz and the other four cores are running at 1.82GHz. But the graphics are identical, Adreno 430, being paired with two variants of RAM. The Flex2 paired the 16GB model with 2GB of RAM and the 32GB model supports 3GB of RAM, noting that the device has a microSD card slot and the memory can be expanded up to 128GB.

The OnePlus 2 has also two variants of storage, and if you’ll settle for 16GB, then you’ll get 3GB of RAM. The more generous internal memory has a capacity of 64GB, but you should know that you’ll be stuck with it, because the manufacturer hasn’t added a microSD card slot to expand it. However, for this configuration, you’ll get 4GB of RAM.

Also, both phablets support Wi-Fi, Bluetooth 4.1, GPS and a microUSB port for charging and data transfer (the OnePlus 2 comes with the new Type-C, while the Flex2 uses the standard 2.0). Moreover, the Flex 2 supports an IR Blaster, NFC and has a FM Stereo radio, while the OnePlus 2 offers a fingerprint scanner.

Cameras and Batteries

Both rear cameras support 13MP and have mutual features such as OIS, dual LED flash and laser autofocus. They are also capable to record 2160p videos @30fps. You’ll be impressed by the secondary camera of the OnePlus 2, which takes better quality selfies than the 2.1MP front camera of the Flex2.

Even the battery of the OnePlus 2 is more convenient, because its capacity is higher – 3300mAh, but it lacks a quick charge feature. The Flex2 has this option, but its battery has a capacity of 3000mAh.
