LG recently announced the LG G4, the company's latest flagship device, and along with the G4 came a plethora of new features and updated applications. Something that makes the LG G4 stand out over last year's LG G3, is the new UX 4.0, which further improves what already was a beautiful user interface and experience. Normally, when a device has just been launched; the company focuses more on said device's development, leaving its predecessors a little behind in terms of how they receive firmware updates. However, this often does not stop the android community from bridging the gap. Senior Member of XDA-Developers, LastStandingDroid, has taken the task of porting all of the LG G4's new system applications onto the LG G3. The company behind the new flagship, still hasn't given any information regarding when the LG G3 is set to receive the new UX, so if you don't feel like waiting for LG to send out the latest UX, to last year's flagship and are comfortable manually installing apps; this is the time to give your LG G3 a new look and feel.
LG introduced with the LG G4, some great new features and updates to their already existing apps, all of which are included with the new UX 4.0. LastStandingDroid, has already brought applications like the LGMusic, LGHome, the updated LGCamera with Manual Mode (although some users have reported this feature to be limited), LGFileManager, and a few others. Every application is individually available to download via zip files so that you can install only the apps you want. In order to install any of the LG G4's applications to an LG G3, your device must first be rooted; due to several changes that must be manually applied to the new app's permissions.
You can download the new LG G4's applications directly from the XDA-Developers thread. If you plan on installing any of these applications, be sure to know that some might not work perfectly on the LG G3, and might slow down your device's performance. These are all ports, meaning that they are not fully optimized to be used on a different device from the LG G4. As such, you should always be aware that things can go wrong and bad things can happen.
