7. You can control your TV with it
This is one of those underrated features that popped up in smartphones a year ago and hasn't yet let go. You can use the LG G3 as a remote control for your television. It's got an infrared port in it that allows the phone to act as a remote, and LG's got its own universal remote software to go along with it. All you have to do is answer some questions in setup, do a few tests, and it just works.
Will you want to replace your go-to remote for a smartphone? Maybe not. And that's OK. But it's a pretty handy feature to have in a pinch.
It's also a pretty sweet way to prank your friends.
