I really like my Nexus 5, but the G3... Battery life is terrible.
Android OS is always at 16-18%, it keeps the wake lock about 1/4 of the time.
Maybe I should contact LG support, so they can tell me to contact Google... ad infinitum, ad nauseum...
Also, difficult to root, and pretty much no ROMs. I'd love to run something like Omega (for Samsung).
Last but not least, the screen is not very bright, and has a distinct blueish - grey tint to it.
On the positive side, I really like their colors and icons (in system apps).
