LG G Flex ships with quad-core Qualcomm Snapdragon 800 processor running a 2.26 GHz clock with Adreno 330 graphics and 2 GB of RAM, which matches what is found on current high-end devices at the time of this review. Its performance is exceptionally fluid, even during the most demanding tasks. LG has upgraded Android OS 4.2.2 with its recognizable user interface equipped with multitasking options.

With 32 GB of data storage, this makes the G Flex one of LG’s most powerful devices. Still, the lack of a microSD card slot is disappointing considering the curved screen seems ideal for video playback.

LG G Flex performed immaculately on benchmark tests, ahead of comparable models and other top-class LG devices. However, it may be that the underwhelming display resolution paired with mild Android OS modifications leave enough power for exceptionally fast processing and multitasking speeds.

The LG G Flex wakes up from stand-by mode by a double tapping on the screen. This is really easy to get used to and seems practical in everyday use, but testers found the phone reacted slowly to taps on the screen, taking up to a second or two to wake up. The process actually takes a bit longer as users still have to unlock the device with a swipe.

Camera and Battery Life

The G Flex features the same camera interface as the G2, which allows users to choose between 12 various shooting modes. The Time Catch option is a great feature for smartphone photographers, as it takes several photos before the shutter is actually pressed, making it much easier to catch the perfect moment. Photograph quality is solid, but not special by any means. The image details are above average, but on the same level as those taken by G2. The colors are properly saturated, except green tones, which seem overly saturated, making nature photos look a bit surreal. However, white balance and auto exposure are immaculate.

The same goes for 1080p video recordings. Quality is solid, but not thrilling. The videos look good on LG G Flex’s curved display owing to its unique shape and despite its shortcomings, and the quality is above average for phablet cameras.

The 3500 mAh battery life impressed testers; while the flexible Lithium Polymer battery is not removable, it still kept the device up and running for longer than 24 hours. However, heavy browsing cut the batter life down significantly during testing. Luckily, this is not the case with media playback, gaming, and app use on the phablet.
