LG G Flex2 review: A new angle

A new angle

GSMArena team, 18 February 2015.

Display

The LG G Flex2 has a new brand screen - Plastic OLED - manufactured by LG. Traditional OLEDs have their light diodes on a sheet of glass, but by using a plastic substrate LG has managed to make the display curved.

The 5.5" P-OLED 1080p display of LG G Flex2

LG G Flex used a 6" OLED screen, while the new G Flex2 bets on a 5.5" unit but with higher 1080p resolution. This means that despite its ample surface, the P-OLED panel offers a great 403ppi - well above the 300ppi or so Retina-grade threshold.

Unlike the original Flex, which used a RGB matrix for its screen, LG went back to the Pentile matrix for the Flex2 but it of the diamond-shaped PenTile variety, meaning every pixel has four sub-pixels and essentially a RGBG arrangement. Here's how the layout looks under a microscope.

LG G Flex2

The default screen mode underlines the P-OLED panel's key strength, high contrast, by producing overly saturated colors that make every image look like it's going to pop out of the frame. Yet, if you aren't a fan of the slightly unrealistic images, you can change the screen more in Settings to Natural, which should display colors as true as possible.

Whatever mode you've chosen to use, the infinite native contrast and the low reflectivity guarantee you will enjoy great picture in brighter environments, plus the viewing angles are simply impeccable. The screen is brighter than the predecessor in both the 50% and 100% scenarios.

Under direct sunlight, the LG G Flex2 is able to retain excellent contrast and stay legible even in the most brightly lit environments.

Battery life

The LG G Flex2 has a 3,000mAh battery, a 500 mAh less than its predecessor due to the smaller body size. A large OLED screen isn't ideal for long battery life, but in the end things seem to balance out.

Web browsing is once again the Achilles heel - the G Flex2 lasted six hours, which not even close to the average in the class. Talk time and video playback are OK though.

The endurance rating is above average at 62 hours - you can expect to go two and a half days without charging, depending on how much web browsing you do.

LG G Flex2

Our proprietary score also includes a standby battery draw test, which is not featured in our battery test scorecard but is calculated in the total endurance rating.

Our battery testing procedure is described in detail in case you want to learn more about it.

Connectivity

The LG G Flex2 has quad-band 2G/EDGE support, quad-band 3G with HSPA+ (up to 42Mbps downlink) for the international version and LTE Cat.6 support too.

Local connectivity includes dual-band Wi-Fi a/b/g/n/ac (that's both 2.4GHz and 5GHz), Wi-Fi Direct and DLNA. There is also stereo Bluetooth 4.1 and GPS with A-GPS and GLONASS.

The handset has a standard 3.5mm audio jack and a Slimport-enabled microUSB port, meaning you can use it to output content to an external screen with an appropriate adapter. The microUSB port can also be used in a USB host mode letting you connect various USB peripherals, but again you'll need a separately-sold adapter.

NFC connectivity lets you transfer files between other NFC-enabled Android devices via Android Beam, and you can also read NFC tags. Oddly, an NFC Tag manager is not included as part of the standard app package, so you'll have to download one from the Play Store if you want that functionality.

Otherwise, there's also support for Miracast streaming for compatible televisions, while SmartShare Beam lets you send and receive files to other LG devices over Wi-Fi.

Finally, the IR-port on the top of the device lets you control a wide variety of electronics and appliances via the QRemote app. QRemote features a large database of TV sets, set-top boxes, and audio receivers. It also gives you the ability to create a universal remote, complete with button mapping.
