LG has released a new app called VPInput that allows you to control your LG smartphone from your Mac or PC. The app, which works with the LG G5, G4, and V10, will let you use your mouse and keyboard to remotely operate your phone. You can input text, send screenshots from your computer directly to your phone, and share clipboard text between the devices.
Although this won't be useful for everyone, it could come in handy in certain cases, as it operates over Bluetooth and doesn't require an internet connection. You can download LG VPInput from the Google Play Store, and the PC or Mac client from LG's website.
