I am personally using this phone since last 2 yrs. All I have to say is, this is a BEAST! Received 2 Android upgrades so far since my purchase and no lag what so ever.
Processor- Android version 4.2.2 Jelly Bean operating system in it. This device is loaded with an entirely new processor from Qualcomm Snapdragon 800 chipset; the G2 features a 2.26 GHz quad core processor. Camera - 13 megapixels primary camera at the rear side.
Absolutely brilliant phone for the money. For people who are ignoring it just because its made by LG, kindly note that Google selected this brand to make flagship and authorized Android devices i.e the Nexus series.
While it’s now been succeeded by the LG G3 and its stunning QHD display, the G2 is still available and at a cracking price making it a really great option if you’re on a bit more of a budget.
