The website lists out a set of features that LG G Flex 3 is expected to feature, and if it does, will make it among the best phones to launch this year, not to mention a uniquely curved display. The specifications that Phones Spot mentions include the latest Snapdragon 820 processor, a 5.5-inch Quad HD display, 4GB of RAM, dual-rear cameras of 16MP and 8MP resolutions and a 8MP front camera. The phone may also launch in 32GB and 64GB storage variants.
Phones Spot also says that just like the G5, LG G Flex 3 will feature a modular design. This would imply that modular accessories like LG 360 Cam and a separate battery module should also work with the G Flex 3 and should offer users better ways to make their phones last longer and take better pictures.
Apart from being among the first non-Nexus phone to launch with Android 5.2 Lollipop operating system, the G Flex 2, along with other flagship phones, was also the first to feature Qualcomm's Snapdragon 810 operating system and a DDR4 Grade RAM which offers clock speeds between 2133 and 4266 MT/s and consumes much lesser power than the DDR3 grade RAM. While DDR2 consumed 1.8 volts, DDR3 consumed a slightly lesser 1.5 volts and the DDR4 can get by with just 1.05 volts! This ensures a longer battery life for your smartphone without compromising on performance.
Back in November of 2015, PC Advisor UK speculated that G Flex 3 will launch with a 6-inch Quad HD display, a Snapdragon 820 chip, 4GB of RAM and 32GB of internal storage. Apart from the display-size, the website's specification-chart for the G Flex 3 matches that of Phones Spot. However, none of the listed-out features in these websites have been corroborated by actual leaks, statements or images from LG so far.
LG launched the G Flex 2 at CES 2015 with a 5.5-inch Full HD curved display with a pixel density of 403ppi, 13MP and 2.1MP cameras, 16GB and 32GB storage variants and a Snapdragon 810 chip.
