Like I said above, it doesn't remove leaked ram. It changes the way the ram is handled making it faster. For some people this fix solved 80% of their lag issues on TW, for others it did nearly nothing.
[Galaxy Note 4 General] Near_07:
how sad i have 45 apps running, maybe i shud also try greenify
[Galaxy Note 4 General] fazdnoah:
i can confirm it works so great!
[Galaxy Note 4 General] TheNewLegend:
I cant find any line that starts with "ro.config.dha" why is that?
[Galaxy Note 4 General] Drizzy xS:
I'm on Alexandr rom and I also couldn't find this line
[Galaxy Note 4 General] v1rtu4l:
me neither, just add all of the lines then.
[Galaxy Note 4 General] alirey:
Funny thing. Note 4 didn't boot after editing build.prop on original original Rom :D

Had to restore system partition...
[Galaxy Note 4 General] Batfink33:
I had a boot loop on POF2 adding the lines, had to restore backup.
[Galaxy Note 4 General] danon.brown:
you may have to change the permissions to 744 after editing to prevent it from looping.
[Galaxy Note 4 General] Drizzy xS:
You know if I add all of these lines, which part of the build. Prop should I add the lines in?

Flashable file

for those who didnt make it and didnt done it yet, i made flashable version to make it easier. .

just flash no wipes needed. :good:

hit thanks if i help

download attached file
[Galaxy Note 4 General] Drizzy xS:
I clashed this file and what it seems to do is like instead of having animations whenever I enter an app or a screen it seems to go sort of go black for a second instead of animating, everything seems faster though it's just weird
[Galaxy Note 4 General] d4rkkn16ht:
Improvement confirmed.

Before this workaround, one or more apps seems to stuck as background processes even after I close it properly & causing overheat + draining battery.

After this workaround, all previous problem gone :D

The Recent button also shows significantly faster response.

For everyone failing to use this workaround:

Make sure you are ROOTed

Use a Linux/UNIX compatible text editor, as Ms Window & Mac text editor is using different "character" to mark a "new line" thus causing bootloop.

Some android text editor also changing the file (build.prop) permission attribute.

ES File Explorer Text Editor is recommended (I'm using it) as it doesn't mess with the file permission and it is also a Linux/UNIX compatible text editor (Android=Linux).

Permission change can also causing a bootloop.
[Galaxy Note 4 General] AlexMullerSA:
Those who confirm its working, what ROM are you running?? Just out of curiosity...
[Galaxy Note 4 General] yussuf007:
I can confirme working in i910f on stock bod2

Thanx OP.

Ps only one thing... this mod kill 1 samsung feature . No more waiting after you using recent button. Before this mod i can light a cigarette or other things before popup recents.

Dont have any #DHA Properties line in my build.prop. 910F.
[Galaxy Note 4 General] megaspel:
I do not recommend anyone flash this. Build.prop varies wildly between firmware and phone versions, this will likely brick your phone until you restore the original build.prop or reflash.
[Galaxy Note 4 General] ariefabuzaky:
Me to .. I think this is for n910c or exynos variant
[Galaxy Note 4 General] Se23:
I flashed this on N910f stock lollipop and it works good. Recent Apps lag is better.
[Galaxy Note 4 General] Near_07:
dont worry, this will not replace your whole build.prop file this will just add the lines indicated by the TS. i tried it many times specially to my N910C. if this will bootloop your device then it means those lines indicated by TS is not compatible to your phone even if you manually add it .
[Galaxy Note 4 General] megaspel:
Oops sorry, my mistake. I assumed otherwise.
[Galaxy Note 4 General] Near_07:
This is how it look like after flashing the zip it wont replace your buildprop file but it will just add those lines at the bottom of it

[Galaxy Note 4 General] equlizer:
Does this work on the 910W8 or 910T?
[Galaxy Note 4 General] d4rkkn16ht:
For anyone asking if it will work on their device:

Nandroid Backup first

Try adding the build.prop entries

If it fails, restore backup

FYI my ROM is in my signature & it's BOF1 version
[Galaxy Note 4 General] danon.brown:
This work for 910T.
[Galaxy Note 4 General] SiNJiN76:
My initial impression is that it works. Before doing this mod I had horrible wait going into photo preview after taking a picture. Now it is pretty fast. Recents? Uhm, it's still there. May have improved...not sure, a bit more time needed. :good: 910T BTW, used [MENTION=6008647]Near_07[/MENTION] 's flashable zip.
[Galaxy Note 4 General] jmcostales:
Flashed your file and UI is noticeably faster.

I have an SM-N910C + Wanam Lite Rom V2.3 + Googy Max Kernel V1.4

Thanks!
[Galaxy Note 4 General] MiniMoose:
Great to see people are having success with this. I'm not 100% sure it works on all models, but there was definately people saying it worked on the qualcom models on the thread on reddit. Looks like the N910C is the poster Child for this to work..
[Galaxy Note 4 General] gekkehenkie11:
Just wanted to add that this won't work for AOSP roms like CM12. But the problems dont exit there in the first place, so nothing to be fixed ;)

Regarding Touchwiz, I'd say it most probably does something for Snapdragon models too, since at least some of the strings are used in the services framework.
[Galaxy Note 4 General] aami.aami:
REALLY? cause im on stock Kitkat rom, the stock one, and just 2 mins ago rooted it, and i still have only 1.5 Gb usage out of 3Gb and when at load, like 4 or 5 apps in background, max memory usage is like 1.9Gb or something around that.

its only been 2 days i have this phone and its International model SM-N910F Snapdragon Variant...

and honestly speaking, from my previous experience, (btw, my last android phone was S4 before i went under the rock with my feature phones :-p ) that stock roms, samsung roms, with almost no tweaking ram usage is best. yes there is a problem with memory leak in KK and worst in LP, but i prefer stock and just root my phone for having complete control.

i even have that 300 fonts mod installed on my phone and have about 10+ apps that i installed.

but thats just me. will be tinkering more with the phone and may be report here as well.
[Galaxy Note 4 General] amazing 3D:
I can confirm that this works with SM-N910H stock Lollipop (Iraq)

the recent button lanches almost 2 times faster.

But before doing this i suggest u make a backup of your original build.prop in case of a bootloop. i used an app called Zipme for backing up my build prop it is very easy
[Galaxy Note 4 General] saadahmed1988:
Thanks to mini moose and near07. I used the flash from twrp on stock rooted lollipop n910c and works like a charm. Adds new line on note 4 buil.prop of ram optimization but hoestly. I can feel the speed in even my keyboard and the response of the phone recent apps is not sluggish anymore. Thanks guyss for the mod!!!
[Galaxy Note 4 General] lummujaj:
i can comfirm this works on note4 dual sim (n9100) >....

can i make one questin about antutu score ? i get so low score in ram speed and ram optimization ?? i get only 50% of "supposed" score
[Galaxy Note 4 General] AlexMullerSA:
Don't think this works that well on the F variant. Recent still takes like 2-3seconds to open
[Galaxy Note 4 General] Drizzy xS:
I can also confirm this too on the F variant
[Galaxy Note 4 General] 2PMintheAM:
Can confirm this works on Sprint Note 4 - SM-N910P Variant.

Noticeable improvement when launching recent apps.

Thanks! ^_^
[Galaxy Note 4 General] dvtmg704:
How do we fix keyboard lag
[Galaxy Note 4 General] thedarkmunk:
I've had virtually no change after flashing the zip on the N910F using SSRom (by SimplRom).

Am I doing something wrong? Do i need to wipe dalvik after I've flashed it?

FYI my recovery is TWRP.
[Galaxy Note 4 General] ultimatepro:
Custom kernel for N910C (GoogyMax-N4) (which I have installed) did that as part of its optimization. Exact same values and changes.
[Galaxy Note 4 General] yurividal:
actually 0644
[Galaxy Note 4 General] Abduvali:
i can confirm it worked with 910C + SimpleRom 4 + Xposed

dont expect big change, it makes slightly faster but noticiable

update: little later start rebooting suddenly several times, remove it finally
[Galaxy Note 4 General] 300:
I can confirm too it worked with N9100 Duos.

Recent menu appears faster and TW is slighty smoother.
[Galaxy Note 4 General] remydlc:
didnt see any improvements. TW is a piece of crap. Unfortunately, is the best for our phones since CM based FW have so many glitches is not worth it.
[Galaxy Note 4 General] koko115:

[Galaxy Note 4 General] quincho54:
I just found this thread and did as suscribes. I can confirm that the note 4 runs more smoothly now and a little bit faster. Thanks for the one who tryed it out first or get the idea to try it on the note 4.

[Galaxy Note 4 General] _Sofos_:
Yes it will still work, it doesn't have to do with the launcher you're using.
[Galaxy Note 4 General] Tuffcheez:

[Galaxy Note 4 General] toastido:
Seems to work well for some memory management on my note 3 N900T. Thanks!
[Galaxy Note 4 General] Exiled44:
Wonder if it would do anything for the Note 4 edge.?
[Galaxy Note 4 General] samep:
I got mixed results with it on Sprint Note 4. I prefer L Speed Mod default settings compared to this.
[Galaxy Note 4 General] masterchif92:
Now funny part is N4 ROM doesn't have half of this codes in source so most effect will be just pacebo. Though codes available in S6 (and so S6 ported too).<br />

Also on N4 some codes for example LMK is hard coded in kernel and build.prop change won't have any meaning.<br />

Actually many build.prop tweaks are actually too old and circulating since ages have no meaning on latest build.

So this thread is useless

I cant find any of those lines on my build.prop im using a N910U with lollipop
[Galaxy Note 4 General] samep:
Add the line that was edited, without the word wrap at bottom. Like this:

#

# DHA Properties

ro.config.dha_empty_max=36

ro.config.dha_cached_max=12

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

ro.config.oomminfree_high=7628,9768,11909,14515,16655,20469

Personally, I tried this but it seemed to make my startup time at boot longer. I prefer Lollipop Speed Mod, but don't use both.
[Galaxy Note 4 General] aew0314:
There is no #DHA Properties anywhere in my build prop file.
[Galaxy Note 4 General] samep:
Neither was there any DHA Properties in mine. Like I said, if you want to test it, add all the lines. AFAIK, that is the complete list of changes to add. Add at bottom, save, verify permissions and reboot. You can also save a backup of your original build.prop as build.prop.bak

There was also a flashable mod somewhere in this thread. I think it just ads the lines to your existing build.prop Not sure if it saves a backup or not.
[Galaxy Note 4 General] Near_07:
Yes the fashable file saves the backup as build.prop.near07
[Galaxy Note 4 General] AndroidWars:
No difference anything. Maybe it works but we wont feel difference.
[Galaxy Note 4 General] daffie:
Nope...indeed, no difference in RAM management after implementing DHA settings. I have done this months ago on my S6 and the difference was rather pronounced. On the Note4 no difference at all.

We'll have to wait for 5.1.1 as it will have many RAM management solutions (as I have personally experienced on the S6 as well).
[Galaxy Note 4 General] lover:
is this fix for KitKat 4.4.4 or Lollipop?
[Galaxy Note 4 General] gabrielgon:
Nothing changed. It continues to kill the 6-7th app, even before hitting 2gb of used ram. Somebody fix this, please :c
[Galaxy Note 4 General] daffie:
Hahahaha that's a riot. Only Samsung can fix this. Btw the new 5.1.1 update will fix it...so just a bit more patience.

[Galaxy Note 4 General] rogerinnyc:
This blog post, that I just discovered, is a similar (but slightly different and easier) approach to fixing (i.e., getting rid of) memory management problems on 5.1.1. caused by SmartManager: http://zapek.com/blog/how-to-make-your-galaxy-note-4-fast-again/. After you do its build.prop edits, you can even uninstall SmartManager and keep Battery in Settings. Hooray -- no more force closing of your apps when there's still memory left -- the Samsung App Optimizing process is a real misnomer!
[Galaxy Note 4 General] gabrielgon:
I can confirm that the build COJ5 (5.1.1) keeps 8 light apps opened instead of 5 (what I was getting from COH4)

[Galaxy Note 4 General] rogerinnyc:
Sorry to hear that. Did you double-check that you typed in the edits right? Did you check/reset permissions after editing (failing to do that can cause a bootloop)? Hopefully you kept a build.prop backup and can restore? It worked great on my 910c running stock with systemless root.
[Galaxy Note 4 General] ahmedrehan:
Is this fix still needed on 5.1.1 COJ5 ?

I recently installed the CA Rogers 5.1 OTA and am having an annoying issue. My signal status icons are oversized and display incorrectly (statusbar displays 3G when I'm on HSPA+). Does anyone know what needs to be modified to display the E/G/H/H+/LTE icons instead of the ones I'm getting? I'd like the icons displaying correctly and smaller as I'm used to (smaller and more tucked away next to the signal bars).

Large 3G icon displaying in statusbar when on HSPA+

Large LTE icon

the size is not an issue mate...

After 5.1 update, yes they look bigger and after a small gap than before....

[Galaxy Note 4 Q&A, Help & Troubleshooting] steve_77:
Ok Noob here (at least in this forum) - tmobile note 4 : Not rooted (yet)

1) should I update to 5.0 OTA or stick with 4.4.4?

2) IF i move to 5.0 does anyone know where i can get original stock tmobile 4.4.4 ROM if i want to go back?

3) I figure If I OTA update to 5.0 and then root - It would be safer than rooting 4.4.4 , but really want to backup my 4.4.4 if possible? How can I do this without root?

4) I heard (rumor) that root under 5.0 is more restrictive than 4.4.4 is this right?

Lastly

Under tis forum i see 2 sun categories:

Note 4 Android Development (Exynos)

Note 4 Android Development (Snapdragon)

How can i tell which processor I have in my device?

Thank you for your patience.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Simplyeduardo:
1. Really its up to your preference if you don't like it you can always go back to kitkat. theirs a lot of guides how to do so.

2. yes go to sammobile or search the forums.

3. there's no way of backing up 4.4.4 without root. you can root 4.4.4 or 5.0.1

4. I haven't really heard this, But really you just try it and if not your liking then go back to kitkat.

5. you have the snapdragon since its from t mobile.

[Galaxy Note 4 Q&A, Help & Troubleshooting] steve_77:
Thanks so much! One last question - If do the OTA update to 5.x through Tmobile - do i need to worry about loosing any data or apps, apps settings, etc?

Im not rooted so cant do titanium or nandroid, but worry about things going missing after update - what should i backup ? or is it pretty seamless these days?

Sorry if this seems like a dumb question - last time i did OTA back on Eclair to Froyo it basically nuked everything.. so though id ask to make sure.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Simplyeduardo:
if you update through ota all your apps and settings will remain there. they just get optimized for 5.0.1. so dont worry about things going missing unless theres a app thats not compatible with loli yet.

hi guys. erroneally I bricked my phone. Actualy I have twrp, unlocked bootloader, s-ON, and no system folder, so the device doesn't start. I only can enter the bootloader, fastboot and twrp. I tried flashing a ROM using twrp but seems that s-on doesn't allow to write on root folder ( / ). How can I do? There is a method to flash the system folder via fastboot? thanks
[HTC Desire 601] alatnet:

system.img is an image of the system partition, like recovery.img and boot.img.
[HTC Desire 601] ekahy:
thanks. Where can I find a system.img for KK ? In this forum I only found a whole OTA update with recovery.img, boot.img but no system.img (only system folder)

I also tried to flash an update.zip from recovery ( twrp) but it didn't work: the recovery could not mount the system , data and cache partition..
[HTC Desire 601] alatnet:
i think you need to update your hboot before installing KK.

Cant remember where to do that though...

Did you try using this:

and follow the instructions correctly?

[HTC One M8 for Windows] Tachi91:
I have a Favor to ask.

If you have an AT&T M8 for Windows and have recently used the Windows Phone Recovery Tool to restore your M8 back to WP8.1 I have a favor to ask.

Can you go to this location on your PC

There should be a subfolder in there with two .nbh files. Can some one upload them so that I can add the standalone HTC RUU install files. Like that those who can't restore using the WPRT can attempt it using separate HTC tools.

This will benefit the community and hopefully help others out of a tough situation.

Please and thank you
