Optimize Galaxy Note 4 RAM Leak Usage Using S6 Build.prop Modification

Samsung Galaxy S6 and S6 edge are not the only Samsung devices to suffer from RAM issues. The Samsung Galaxy Note 4 has joined the boat after hundreds of users have been complaining for poor RAM management on their devices. The fact that both the Galaxy S6 and Galaxy Note 4 have 3 Gb of RAM is not enough, as Samsung’s skin TouchWiz is so heavy and bloated that even high-end devices suffer from RAM leak issues.

A few weeks ago, Galaxy S6 users found a solution to the annoying high RAM usage. Lollipop doesn’t need more than 3 GB of RAM to run smoothly, but Samsung hasn’t optimized the Galaxy Note 4 software properly, so you need to manually optimize it yourself.

A few Galaxy Note 4 owners discovered that the old fix for the Samsung Galaxy S6 has turned out to work perfectly well on their devices as well. The fix has to do with the modification of the build.prop file by changing some RAM values, which allow for better RAM management. The fix works on both, the Snapdragon and Exynos variants of the Note 4.

If you too have a Samsung Galaxy Note 4 and want to fix the high RAM usage and have a smoother device which does not lag, follow the guide below.
