Whether you're watching a movie, or just reading some text, you can do it while your handset is recharging its batteries sans wires. And the phone can be supported in both portrait and landscape mode.
From what we can see, it looks like this accessory will be available in white only, and unfortunately, no pricing information was leaked. If you're planning on buying an LG G3, this is one additional purchase that you might want to make.
Thanks for the tip!
