LG has unveiled the fourth iteration of its Android-based UX, which contains a variety of new features that the Korean smartphone maker claims to be "human-centered."

Simply dubbed the LG UX 4.0, the updated platform is expected to make its debut on the upcoming LG G4, LG's anticipated new flagship smartphone that many believe LG will launch on April 28 at a media event to which LG has sent invitations.

The new UX, which was announced over LG's Korean blog and via a YouTube video by LG Mobile Global, comes with a variety of new features that aim to make the user experience easier and more convenient for users by allowing them to customize it for their own needs and gain access to information they need the most.

One of the more remarkable features touted by LG is Quick Shot, which allows users to quickly open the camera app by pressing the phone's down volume button twice. Users can also switch the camera into Expert mode, allowing the app to automatically group photos together in a single album based on the photos' location. Quick Shot isn't actually new, since Samsung introduced a similar feature in TouchWiz for the Galaxy S6, but this is the first time LG users will be able to use a shortcut to open the camera.

LG also introduced a couple of smart features to help users get the information they need. One of these features is Smart Alert, which shows information about the weather and offers suggestions on what to do and when. For instance, if a user likes biking, running, or going to the gym, Smart Alert will serve up information about the best time of the day to do all these things. The Smart Board gathers information from different sources, such as the user's music, health, and calendar apps, and drops them all off in a single widget so the user can get all the information he needs at a single glance.

Other new features include an updated Calendar that lets users drag and drop events from other apps, such as Facebook and other social networks, and a new Gallery that groups photos into albums based on the date or location of those photos.

LG's UX easily became one of the better platforms compared to the bloated TouchWiz by Samsung and HTC's Sense when it introduced a feature called Knock Code, which allows users to unlock their device simply by knocking on the screen twice.

Little else is officially known about the LG G4, aside from the fact that it will sport a Quad-HD display. LG itself has announced in a press release last week that its newest smartphone will have a 5.5-inch LCD panel with a 1,140 x 2,560 resolution and 538 pixels per inch. Rumor has it that the new device may be powered by a six-core Snapdragon 808 chipset and have a 16-megapixel camera.
