Is it just me or does it seem like LG has blatantly ripped off some of the Samsung Galaxy features? One of the most obvious is the Splitview although there are others like their own version of smart stay, and one handed functionality. This phone reminds me of more attractive younger sister of the Note 3 at times.
The big issue with Splitview is that it has very limited support. You can only use it with a few of the LG apps. If you would like to use this feature with all of your apps no worries, xda usere "annoyingduck" has you covered. His mod will bring support for every app on your phone to splitview. You will need to be rooted and have a basic understanding of how to edit a build.prop. Head to the link below for the full instructions.
