Things to know:

Instructions

  1. Make sure your device is rooted. If your Galaxy S6 is on Android 5.1 (coming soon on Note 4), here’s your root access.
  2. Download ES File Explorer android app.
  3. Open the app, and then swipe from left edge to right, to get options menu.
  4. Tap on Root button under the Tools section. Provide root access to app by tapping on OK when pop-up shows up.
  5. Now, go to root folder of your phone, and then into System folder.
  6. Find the build.prop file there. Copy it to any folder on your internal storage or external sdcard, or even better, on PC.
  7. Edit the build.prop file as said below.
  8. Tap on the build.prop file, and then select ES Note Editor to open the file for editing.
  9. Tap on 3-dot button at top right, and then select ‘Edit’. Now we will edit the build.prop file. Make sure your editing is correct letter to letter, word to word. A mistake of one character here is enough to send your phone to bootloop, and you will be required to either restore the build.prop file via ADB from recovery, or install a new system/firmware again.
  10. Now, find the line given below and change its value to what is given below. 
    ro.config.dha_cached_max=12
  11. Change the value of this line too. On Note 4, you may have to insert this one as new line, as it might be there already. 
    ro.config.dha_empty_max=36
  12. Now, add these 4 lines, next to above line (empty_max). 
    ro.config.dha_th_rate=2.3
    ro.config.dha_lmk_scale=0.545
    ro.config.sdha_apps_bg_max=70
    ro.config.sdha_apps_bg_min=8
  13. Remove the duplicate entries of the above 4 lines. You have to find them yourself and remove them because we already have these values. Simply adding a # sign before line’s start disables it, you can do that too to disable a particular line.
  14. Finally, change the LMK values on its line. If you don’t find this line, then simply add it after the above lines (that is, ro.config.sdha_apps_bg_min=8). 
    ro.config.oomminfree_high=7628,9768,11909,14515,16655,20469
  15. Double check everything. All changes that you made and all lines you inserted or deleted/disabled. The smallest of error here could send the pone into bootloop.
  16. Tap on the back arrow button in top left. And then on Yes button to confirm the save.
  17. Tap on back button again to come back to system folder.
  18. Long press on build.prop, then 3-dot menu in bottom right, then select properties, and now tap on change button besides Permissions. Select all 3 rows for Read column, while only Owner row for Write column. Leave all other checkboxes blank. It should be as shown in image below.
  19. Tap on OK, and then back button two times, to reach system folder again. Exit the app.
  20. Reboot your device now to apply the changes. If you edited build.prop correctly, then it should reboot all fine we hope you see significant improvements in using your phone. Good luck!
