Pre-req:
-Root
-some type of editor, if you are using root explorer it will have it own editor
-Decent knowledge of android file system
so in an attempt to fix this multitasking/Ram issue that is plaguing Samsung devices. I have come up with a fix for our devices (with the help of @mikeyinid)
1. open up root explorer
2.Navigate to /system
3.open up build.prop (keep in mind the file permission of the file, after you done editing you will have to change the file permision back rw-r-r)
4. paste in the following line at the bottom of your build.prop
ro.config.fha_enable=true
ro.sys.fw.use_trim_settings=true
ro.sys.fw.empty_app_percent=50
ro.sys.fw.trim_empty_percent=100
ro.sys.fw.trim_cache_percent=100
ro.sys.fw.bservice_enable=true
ro.sys.fw.bservice_limit=5
ro.sys.fw.bservice_age=5000
ro.sys.fw.trim_enable_memory=2147483648
2147483648 is the ammount of ram in bytes. so in this case 2gig
Check for the following
ro.config.dha_cached_max=
ro.config.dha_empty_max=
ro.config.dha_th_rate=
ro.config.dha_lmk_scale=
and delete them. I dont think it would be in there since 5.1.1 utilized FHA instead of DHA
5. edit the following line
dalvik.vm.heapstartsize=8m
dalvik.vm.heapgrowthlimit=256m
dalvik.vm.heapsize=512m
dalvik.vm.heaptargetutilization=0.50
dalvik.vm.heapminfree=4m
dalvik.vm.heapmaxfree=16m
ro.hwui.texture_cache_size=72
ro.hwui.layer_cache_size=48
ro.hwui.r_buffer_cache_size=8
ro.hwui.path_cache_size=32
ro.hwui.gradient_cache_size=1
ro.hwui.drop_shadow_cache_size=6
ro.hwui.text_small_cache_width=1024
ro.hwui.text_small_cache_height=1024
ro.hwui.text_large_cache_width=2048
ro.hwui.text_large_cache_height=2048
save and make sure to check permission reboot....follow up, let me know.
so far so good for me .
Thank you for this! I'm sure this information will spread fast.
With that said, I'm curious about something. With Samsung, in their infinite wisdom, this highly controversial issue could've been easily prevented with simple build.prop edits. But why didn't they do so? Why do you think they didn't follow through with this before launching the device? Could it be that "further" utilization of memory wouldn't have yielded them the battery life that it comes with, stock? Heck, I dunno. I'm gonna definitely try this though.
Thanks again!

That's exactly why people are saying they are doing it for. For battery life
IMO, the reason Samsung doesn't make these simple changes is because doing so causes the device to slow and become laggy over time. So they're killing apps very aggressively to (in theory) keep the device running smooth. Anyone coming from the S6 will know that even with Samsungs default memory settings the device can still become slow and unuseable over time. So it's a tradeoff. I persoanlly prefer the multi tasking with a reboot or two a day over killing apps and having to reload every time you switch to an app. Also @ OP, the value you set for the trim setting, 2gb or whatever. What did you find that made you come to that value?

Something is wrong if it needs to aggressively kill apps like it does to keep from lagging and needing a reboot. I mean android should be scrapping the earliest used applications from the ram as the ram is needed. Unused ram should have no affect on the system itself. You could have a badly coded app using a portion of ram but still bog the system down.
Having to restart once a day is going backwards to blackberry days when it was damn near in the manual to restart once a day.
I can see the savings in battery in regards to less cycles of the cpu when you aren't starting apps fresh everytime you want to run it

The problem is Samsung is using DHA/FHA rather than Google's LMK. We know very little about the way Samsung is managing memory. From my observations, the device becomes slow/laggy when the swap gets full. Since Samsung is the only one still using swap that is another issue all by itself. Making swap larger than 1.4 GB does seem to extend the length of time it takes for the device to start lagging but it doesn't fix it. Getting rid of swap altogether creates a whole bunch of other issues. It's really been a nightmare trying to figure things out regarding memory management on these arm64 devices.

I was googling around and find that it was implemented in other phone, and one of the number was a weird 10xxxxxxx number, so I google that number and it equates to 1gig so I take it as 1 gig of ram in bytes. Since note5 have 4 gig of ram I decided to put 2gig there, basically I'm shooting in the dark and hope that it works, so far its good, no random closure or reboot.

well there are many reason why they implement this way. I think its because they are trying to maximize battery life, so if a phone screen is off, it means that the user are not using it so it force the app to shut down quicker, making the cpu going into deep sleep quicker therefore save battery life. It also suppose to make the phone seems quicker because its not being bother by unused process and ram.
TBH its a good implementation, regular user wont know a difference. I feel the issue is being pressed because XDA is full of nerds and they want their phone to be equally as good as a regular Ubuntu desktop, why does one need to multitask 10-12 apps on a phone? doesn't make sense to me.

Hmm. It's interesting Samsung went with the same size swap Note5 despite the device having more ram. Also, had you just reboot when you ran that?

Probably a stupid question but why do I have so little ram showing? Right now I have 531 in total according to this:
Shouldn't it be nearer a gig?
No. The OS uses a good amount of it. As it should.
If you want to see more info on the memory, download an app called 'Quick System Info' free from the market.
I love how Asus included a screen capture utility with the Transformer. How do you use it to take a shot?

Awesome, thanks!
I noticed this too.
I downloaded and installed Quick System Info, but that shows total RAM as being 729MB !!!!!!!!!!!!
I spoke to Asus support about this, who didn't really have a clue! The girl there confirmed that their 1GB test model also showed the same RAM under settings (531ish), but didn't have quick system info.
She reckoned that the OS would be using the rest, although I didn't believe this. Surely system info would still report the RAM that the OS has reserved, but just show it as unavailable? Also, 295MB sounds like a lot for the OS to steal. They'd have no chance of installing Honeycomb on phones, that often only have 256 - 512Mb total RAM to start with!
She then tried to blame it on the different calculations that they use to calculate Gigabytes. This is usually down to taking 1mb to be 1000 kb, rather than 1024kb. To lose 295Mb out of 1024 would have to be one seriously optimistic calculation!
Anyway, if anybody can come up with a proper answer to this, I would like to know where the RAM has gone.
Does anybody have a Xoom to compare to? Surely that should show the same.
Don't forget that the GPU will be wanting some of that RAM as well, so we can maybe expect 128mb of ram to the GPU.

this post illustrate users and vendors story on Memory Free when its sold, and when enduser buy it.
Like getting a 1000GB Hardrive, you never get 1000GB out of it.
in our case the kernel can be configured to allocate what memory block size is allocated for gpu and vm.
but before all this happens, you machine do ineed have 1024MB memory.
I just double checked. This issue is also present on the Xoom.

Strangely they are 263 and 80 which clearly dont add up to 512 or 1024, i swear that during ics it said that they were 1024 and apps still seem to from my screenshot above. And i remember the employee saying it had 1gb
343mb is a typical amount provided by stock, around 50mb+ is kept by the system (codecs or something from memory? bigmem ditches most of it) and the rest is used by the GPU, overall adding up to 512mb of RAM, which is what's in your phone
That link 404's on me, so another would be appreciated. If you have busybox, download that and type in terminal emulator/adb shell:
free -m

I am not sure this is a good idea. The "drive" in the Samsung Galaxy S4 is (like) an SSD as it supports TRIM.
There is a lot of open/update/close/delete going on which leaves lots of data to purge.
Lets say I write to a file called TEMP.TXTthe word hello. On the drive it writes this (simplified):
Drive *=in use/valid x=invalid but not purged e=empty
[*****eee][eeeeeeee]
Data:
[hello]
Now if I go and update TEMP.TXT to and change hello to seeya, it now looks like this:
Drive *=in use/valid x=invalid but not purged e=empty
[xxxxx***][**eeeeee]
Data:
[seeya]
So it doesnt update the block of data because it is "too expensive" performance-wise so it writes to a blank space.
*Expensive is read the data in that block, format/blank out the block, modify the buffer for the new data, write to block
*its always fastest to write to an empty block
On occasion, the drive will initiate a garbage collection stage which takes the invalidated areas of the drive and sets them back to blank
*Google TRIM SSD for in-depth SSD functionality
SSD are overprovisioned(OP) on purpose for performance reasons and longevity. This means if there is a 128 gig drive, it advertises 120 gig drive. The OP is like guaranteed blank area.
Now when the drive gets 85% full or more, it has that 8 gig read/write/update/delete available still and performance is still great
If you remove the OP and use the entire 128 gig, as it gets 85% full and more, the performance of the drive reduces as it is reading/writing/deleting to areas that are not blank so the drive tells the OS to wait while it gets the area ready and then the phone feels sluggish
I purchased android turner application and this has aTRIM feature. I scheduled that to run every 3 hours and it reports it clears anywhere from 24 meg to 3.89 gig. I let my buddy check out my phone to check out a game, and he goes "wow everything on your phone is so fluid". He has a Galaxy Note 2

On the TOP bar thing, click FS TRIMMER
It will show /system, /data and /cache and at very bottom a button that says TRIM
Click it
you can also set it to apply on boot...but I have mine scheduled to run every 3 hours which is probably overkill but hey.... what the hell, right?
FYI, I have System Tuner and did not see TRIM in it. I didn't look very hard though. Was too busy being annoyed that System Tuner did not become what Android Tuner is. And Android Tuner is like 4x more expensive.

I'm not talking about censorship; I'm talking about responsibility. It is irresponsible to post a promise like that and link to something that will almost certainly hard-brick any i337 on which it is flashed.
It will most likely fail to even flash...from what I've come up with we can't even flash our own pits (I've tried) they say successfully flashed but nothing else changes, a pit flash SHOULD delete all data on a phone and wipe the partitions/reset them...however with the s4...it just boots back up like the pit was never flashed

There is always the chance that it will flash, though. Chance is not good with a $650 phone.

Anyone else notice this?
For example. I'll open up chrome, go to a webpage, exit chrome, and then when I come back to chrome it starts reloading the page again. I've noticed it refreshes or restarts a ton of apps after I come back to them after a short amount of time and it never puts me where I last left off in the app. Even my two year old phones keep apps open longer.
What's up with this?

You have to setup your device properly then you have enough free ram for multitasking. Out of the box the system alone uses like 2gb+ of ram which is to much imo. Stock lollipop uses around ~500mb of ram. After all these years touchwiz is still a ramhog nr.1
Just some quick tips:
- use stock launcher from google or nova or other lightweight launchers
- deactivate facebook and messenger and almost every google app that you dont use
this alone will save you like 500mb ram alone. Everything else you'll find in the ram usage settings from there you can see what uses most ram and if you dont need it just deactivate or deinstall this ****.

Problem is that I did not have this problem on my Note 3(with lollipop 5,0) so why should I have it on the touchwiz "lite" on the S6? same RAM on both devices.

This issue is discussed in the other thread, but this one is appropriately named. The issue is driving me nuts, but I didn't find anyone else complaining until I saw this thread.
Bloat or no bloat, it's incomprehensible to me how you can't even have three apps running on a phone with 3 GB of ram. My OPO could easily have six or more apps running at the same time.
Well, my galaxy s6 is going back to T-Mobile. LG G4 here I come.
I don't think ram is the issue. I just checked: system is using 1.2gb of ram and apps using 400mb. I have over 1gb of free ram. That's a ton.

I really like the phone too, but I'm constantly down to about 200-400 MB of RAM although I've removed most of the bloat and I'm not running any weird apps that I haven't used on other phones in the past.
Not too keen on rooting cause of all the warranty issues either...sure hope you're right about them fixing it.
You're not supposed to have free RAM...
Android’s operating system has its own native handler for assigning RAM to apps and making sure that all of it is being used in the most optimal way. In fact, Android purposely tries to keep apps loaded into RAM for better performance. RAM is fast, remember? On mobile devices, every bit of speed is critical for a good user experience, so keeping apps in RAM is actually a good thing.

There definitely seems to be an issue with apps being closed too quickly but I don't think it has anything to do with the free RAM numbers you're looking at.
I wonder if there is anyway to submit something to samsung so they are aware of this issue. If this wasn't an issue, this phone would be nearly perfect.

Thanks, I know this. Doesn't change the fact that my OPO had about 600 MB more free RAM at any given moment and multitasked like a champ.
Hope they'll fix it soon.
Really don`t think it`s the issue with to low RAM, I belive this is a management issue or a bug thats just kills the apps to quickly or even maybe lollipop 5,0,2 issue that samsung missed? I sent samsung a mail about it yesterday so hopefully they will contact me back.
I'd be very interested to know whether someone who has rooted and changed the minfree settings still experience the issues described here.
Also, did you receive any response from Samsung, Johan?

Call Samsung customer support. I did for the flash remaining lit, and they weren't even aware of it. We need to be notifying Samsung of these issues, not our carriers.

Saw this as well. Wanted to see if this worked on the VZW S6 as well before taking the plunge.

I looked into making the changes to the build.prop but ours is pretty different than the tmobile version. The instructions state that not all S6's will have the same lines to delete but they also mention that leaving duplicates will cause a bootloop. I don't feel like having to odin and wipe my phone if it doesn't work and at this point I cannot nandroid. I will wait for someone braver than I to post their results here :fingers-crossed:

I added the lines and deleted the duplicate lines (was about 3 or 4 lines)
Did seem to do the trick.
**These are the lines i used and**
#MultiTasking Tweaks
ro.config.dha_cached_max=15 - duplicate line
ro.config.dha_empty_max=42 - duplicate line
ro.config.dha_empty_init=42 -duplicate line
ro.config.dha_th_rate=2.3 -duplicate line (maybe cant remember)
ro.config.dha_lmk_scale=0.545
ro.config.sdha_apps_bg_max=70
ro.config.oomminfree_high=7628,9768,11909,14515,16655,20469
Yep. I did the same thing, and I'm not getting as many redrawn at all. Apps are definitely staying in the state I left them instead if restarting. Very happy.
Scrub that.
My phone was sitting in my pocket for 10 minutes, and when I went back to the apps, they all restarted. I hadn't noticed this much before now, but it's annoying me now.

Eh. I went for it. Just a heads up to others, there was only 1 duplicate value for me to delete, not the 3 or 4 that most people are reporting.
Not sure why the differences but my phone didn't get stuck in a boot loop :good:. I will try to remember to post back after using the phone for a bit to see if there is a noticeable difference.

Thanks for the reminder!
Overall, switching back and forth between apps does seem faster. I haven't noticed any slow-downs after extended periods of time (2+ days without restarts). The phone doesn't run any hotter, battery life seems the same. Apps still reset after a while though, relay for reddit is something I use quite often but if I don't use it for a few hours it reloads.
I was hoping this would solve a slow-down issue that I am having where I am running spotify, waze, and textra's pop-up response (as a passenger of course). It didn't, the phone still slows down in this situation.
Overall, I don't see any downside to the tweak, so go for it.
Just a thought. Has anyone thought about using an apps2sd type of app to free up memory space? I remember having to do this years ago on an older phone (probably an older nexus)
Admittedly we shouldn't have to be doing this, but needs must.

This literally has NOTHING to do with RAM. RAM does not equal storage space. What you are referring to is freeing up storage space -- again nothing to do with RAM. Secondly, there is no SD card space, so this does not even make sense to do on the GS6.
Now, I have a question for those who have edited the build.prop. Has anyone used Root Explorer to do so? Secondly, to avoid bootlooping, did anyone change permissions of the build.prop file? To quote someone from a different forum:

after editing make sure permissions are 0644 on it or you will boot loop.

Have you guys changed permissions to this? I want to mess around with my build.prop but don't want to boot loop because I'd have to Odin and it'd just be a hassle / annoying.

Sadly I agree with you. It sucks that on vzw we have to pick between choices that imo each have very negative things about them.

I changed my build.prop file using root explorer (long click and edit in text editor)
When I saved it, it gave it the right permissions as far as I could see. It also backs up the original file as well.

Also, I trusted Samsung to have given some thought to memory management themselves, and not have us figure it the f**k out. I thought I was done with this years ago.
My retired moto x on Kit Kat is far superior to this phone in many regards.
i'm just frustrated. This is an expensive-assed phone, and it looks like we are being treated as guinea pigs. Not a pleasant feeling.
Just did this and restarted, phone seems to be a little snappier though my RAM still shows pretty low. System is taking up 1.3gb down from 1.4gb and my free is hovering around 800 mb. still not ideal but not terrible.

Over 1gb free would be ideal. I dont have a lot of apps running besides a few email clients and messaging apps, and I'm running CleanROM as well.
