The following are two ram optimising scripts that actually do something. They will ensure a fluid experience by keeping a minimum of 100mb of ram free. Simple as that.
STEPS:
Download zip and extract files "boost" and "freeram".
On the tablet , use a root file manager
Paste files in /system/bin (system needs to be re-writable obviously)
Set permissions to rwxr--r--
Activate scripts manually after every boot using android terminal emulator:
1) free ram (to see ram usage)
2) su
3) freeram (no spaces)
4) boost
5) free ram (to see ram usage - compare to values in step1)
6) Profit
Explanation:
"boost" - activates Adrenaline Boost V3 (i take no credit for this script). What this does is clear the ram cache, freeing up ram storage.
"freeram" - a script i made, adjusts minfree values (android's built in ram manager) to kill off more empty apps from ram when ram usage exceeds certain values - not a task killer, so doesn't affect battery life
In android terminal emulator:
"su"
"cat /sys/module/lowmemorykiller/parameters/minfree"
-will show you the prior minfree values, "freeram" script adjusts these to 8192, 10240, 12288, 21000, 23000, 26000
Notes:
All changes reset on boot, so you'll need to to run everytime you reboot
check your ram usage before with: "free ram"
These two scripts will generally ensure about 300-400mb free ram always.
Removing widgets will improve this also.
If after a while nexus is feeling slow again, run "boost" script.
Fstrim or "lagfix" also helps with those having slow emmc issues
Enjoy more free ram

didn't know about that app.
This is more geeky and cleaner though, who doesn't want to use terminal??
And i don't think the app flushes the ram cache (similar to the adrenaline v3 script)
According to anandtech:
"I’m told that TRIM support has been part of the eMMC standard since around version 4.2, it was just a matter of enabling it in software. The result is that the new Nexus 7 shouldn’t have these aging affects at all. Better yet, fstrim support has also been added to the old Nexus 7 with as of the Android 4.3 update, so if you’ve got a Nexus 7 that feels slow, I/O performance should get better after fstrim runs in the background. I'm checking on whether the other Nexus devices have also had TRIM support added. I would consider the slow storage aging problem fixed as of now, and Google took the eMMC and storage I/O performance issues with the previous Nexus 7 to heart for this version."

So that's good news for poorly ageing nexus 7's, just update to 4.3 instead of running lagfix
@mods: close/move the thread please.
this is another minfree / lowmemkiller script like Supercharger V6 which offers nothing more than actually less memory. What do I mean? It makes the device start killing apps/processes much sooner rendering it multitask-less. Provides a boost but at a terrible cost: much less mem available to apps...
I was able to multitask smoothly between 8 open apps without reloads. And I've been using this setup for 2mths or so.
I had memory issues with my n7, and this solved them, and I wanted to share as users (can't remember the thread name) were discussing slowness due to limited free ram, and this worked for me.
Mods feel free to close, sharing experiences is not appreciated obviously..

Thanks for sharing it! :beer:
On linux systems having a little amount of free ram is not necessarily a bad thing. it means that the apps you use most are available to be opened very quickly.
OP: what do you mean by "empty app"?
Appreciate your effort, OP. However, a more user-friendly way is to install an app like Rom Toolbox(and others) and change minfree. RT has presets, and set at boot features. I personally subscribe to the thought process that unused ram is wasted ram.

I wish My poorly aging Nexus 7 hasn't improved at all since the 4.3 update. In fact I think it's running even slower. I haven't run lagfix since the update though since I lost root and I'm waiting for Wug's updated toolkit to get it back. (I know I can restore root with other methods but I'm lazy and toolkits just make it easier.)
Aside from the TRIM issue I loved my old Nexus, but 16gb just wasn't enough space anymore and any time I dipped below 4gb of remaining storage it would lag so horribly I'd have to wipe the whole thing and start over if I wanted it to be buttery smooth again, even after using lagfix. Lagfix helped a bit, but it was still crawling compared to a freshly wiped tablet.
I've got a 2013 Nexus 7 on the way though so hopefully what you said about TRIM on the newer model is true and this one won't age as poorly as the original. Even if it does, having an extra 16gb of wiggle room can't hurt.
My thoughts
The most aggressive lvl on the minfree script is 26K ie 26,000*4/1024 = 101mb
Having less than 100mb of ram (ie over 90% ram used) slows down my n7 and its really bad when i have 19-45mb of ram left...
The fact that the script resets on reboot means i can easily compare the difference, for ME it helps and i can't notice an impact on multitasking (and thx for teaching me how to use terminal to check ram usage )

Sorry if this question has been answered somewhere, but I searched and couldn't find a reliable answer. When I go to task manager, it always shows memory usage out of 328mb available. Everything I read prior to purchase indicated there was 512mb ram. If I'm going to be locked in contract for any extended period of time I definitely need more than 328. 512 is already low by today's standard, but 328mb is ridiculously bad. Anyone that knows the answer and a way to verify would be greatly appreciated as all the searches I do come up with both answers.
Thanks for the help guys.
Sent from my SCH-I510 using Tapatalk
In addition to the above mentioned issue... I frequently have 250+ out of the available 328 used even when task manager indicates no apps running. Is there that much going on in the background? In case this helps I'm running the ED2 debloated rom so I can't imagine how bad it would be if I still had all the bloat in there.
Thanks again for the input
Sent from my SCH-I510 using Tapatalk
The phone has 512MB total, with some of that allocated to the system that can't be used by apps. This memory goes to thinks like the GPU to give you that stellar video performance. Sucks that it can't be changed really, but that is how it's setup. I believe that we can get a few MB back from the system, but you won't get all of it back.

Thanks a lot for the response. Makes me a lot more comfortable with holding on to this guy. There must be some serious bacground processes going. because I've yet to see anything lower than 180mb used (about 150 available) and that's with autokiller at extreme preset, which I normally wouldn't set so high...I just wanted to see if any additional mb's would free up.

Ok, android 101:
Android uses smart caching and background process management to keep your apps available and running smoothly. As such the more RAM you have free the more you are WASTING. This system is designed to run up to 99% RAM use before turning off any running apps/background processes.
Ever since android 2.2 it has been HIGHLY efficient at doing so. Using autokillers to keep RAM free is pointless, as most apps don't even use ANY CPU when in background, unless they perform background checks for things like is it your turn on words with friends, etc. Unless you have an app that uses too much background data like this (in which case I'd just get rid of the app...) then using killers is pointless, let the OS run the way it is designed to do. Ever since I listened to a ROM dev and stopped using task killers my battery life on my original droid has nearly tripled, and I'm overclocking it from 566 to 1200mhz!
Android is not windows 95, you don't need to hold its hand and make sure things are closed, doing so actually defeats the advanced features of the OS, decreases battery life in all but a very few cases, and increases your app startup times, keeps you from getting background updates properly, etc.

I was always of the impression that an app such as autokiller differed from a standard task killer in that it modified the values at which android natively kills off processes vs me going in and manually closing an app (which i never do). I too have read articles that task killers are pointless and do more harm than good, but I always thought autokiller was a different sort of "tweak" if you will. I've even seen several devs promote that they've modified androids native memory management to be more aggressive, etc...which is what I thought autokiller accomplished. Autokiller simply seemed necessary to me with the Charge because I was experiencing lag and lockups even with a debloated rom and voodoo kernel. Clearly there could be several culprits to this this and I was simply testing out different fixes and seeing what the results were. Thanks for the heads up though...learn something new every day.
What is the verdict on these memory optimizer type apps?
http://andrs.w3pla.net/autokiller/faq
I can't recommend Autokiller highly enough on Samsung Froyo phones. It was a must use, even with Voodoo, on my old SGS i9000, and the same thing on my Droid Charge.
True story: just this morning I was ready to throw my Charge against the wall in frustration. Ever since upgrading to EE4 the damn thing was LAG LAG LAG city, even with Voodoo. Phone was snappy as heck after a reboot, but after a couple of hours use, it started to lag, and then would get so laggy it was almost unusable. Seriously, opening apps would take 10 second. Auto-rotate the screen took 4-5 seconds.
I enabled Autokiller, set it "aggressive" and the phone's a speed demon again.
Try it, can't hurt your phone with it, might help it exponentially.
waiting for the phones built in lowmem killer is useless, use autokiller and you will notice an immediate improvement in phone response time. heres a point for ya, without it installed i have 78mb ram free,,,with installed 158ram. thats huge. for a phone. plus they dev just updated to reduce memory usage of the app itself, plus there are tweaks in the settings menu to make the IO scheduler more aggressive, improve sd card reads, battery life, wifi, networ,...its layered man. and free....whats more to love. the only other way i have found to improve phone speed feelwise is with kangfucius kernel and set that terd up to 1500hz with cfq. shazaam.

Basically what you're doing is tweaking the settings for how Android frees up your memory. In theory, it should be good, because the defaults that were picked with the Android release aren't going to be appropriate for everyone. Just be careful not to be too aggressive or you might start losing functionality you want, such as alarms or background email checks.

Good point on not being too aggressive. The higher you set it, the more sticky sports ate pushed out of memory, so with the settings I have right now the phone kills some things that in the oat would have been running when I went back to them. I'm going to drop down from aggressive to strict and see if that's a better balance for how I use the phone.

Call me crazy but...
Android is linux based right? I.E. it uses a linux kernel? I was under the impression that was true. If so, unless you're running into the problem of completely filling RAM and having to wait for stuff to be cleared, this kind of thing will not help you!
Linux intentionally leaves commonly used items in RAM in order to decrease access time. It is perfectly normal for such a system to run at 70-80% memory usage. It is, in fact, a GOOD thing, because it means more memory is actually being put to a potentially useful purpose.
That being said, if you're actually running out of RAM I suppose something like this could help.

Yes, yes, I frequently give the "in linux free memory is wasted memory" whenever people want to use some taskkiller app because they want a lot of free memory. This isn't about shooting for some high free memory number because we're Windows minded and think we need a lot of free memory, this is about finding the right settings for Android's own memory manager to keep the phone responsive. There's been something about my Samsung phones (except the Nexus S) where they just get laggy as hell with the stock memory manager settings.
As described above, my phone was almost unusable after a couple of hours booted up until I enabled Autokiller. Maybe something I'm running has memory leak; could be, but I pretty much run the same apps on all my phones, and the HTCs and Nexus S don't get laggy like the i9000 and Charge do.
This app, or the one named MinFreeManager really help. In the early days of the i9000 on MoDaCo site we were using the cat command to tweak the settings manually in our efforts to find a way to stop RFS lag before Voodoo came along.
I just installed this yesterday and configured it for strict mode. I also enabled all of the advanced system tweaks and so far I haven't noticed much if any difference, perhaps it depends on your individual usage and what apps, launcher, etc you're using. I'm going to leave it on and see how it goes though.
Any still using this? Any want to share what settings they use?
So i'm getting pretty unhappy with my Charge, the screen is wonderful, but the battery life, call quality (hissing and popping), and data connection reliability are really pretty hard to bear.
And i think its all Samsung's poor software support to blame.
However, I really dont know if i want to keep this phone or move to another, and one of the deciding factors is the RAM. The phone supposedly has 512MB, but when i goto task manager, i always see that there is 291(ish) of 373 free MB. I know that free memory doesnt really matter due to the way that Android manages things, but on the other hand, in real world experience i get re-draws all the time on launcher telling me that the O/S killed the launcher due to low memory!
Ive tried all kinds of ROMS and stock btw, and this is an obvservation that was consistent on Gummy 2.0, Gummy FE 2.0, InfinityRom Beta (10/13), EP4 leak, and now on Humble 5.0rc2
This is when im not running any apps at all. I understand that the O/S and launcher will take up some, and 291 seems fine im sure some of that is cached etc. But why is 373 the maximum that could be free? If the O/S and launcher are in that 291, what is occupying memory from 374-512???
is 512 enough to run on for the next year? We dont really know how much ICS will take.
512MB is the total RAM onboard, but a portion of that system reserved, thus 373MB available. GB is better than Froyo...it had 327MB available.
I highly suggest using the v6 supercharger script. After running the script select option 7. I never get redraws and don't use a task killer. Android keeps me at atleast 90 MB of free ram all the time. I also ran the loopy smoothness script and added my most used apps to the script so they stay in cache all the time. It is now faster than my evo ever thought about on cm7 and it had over 190 MB of free ram
Can someone explain the overlap between Fugu Tweaks, LoopySmooth, and supercharger? Does it help to patch all 3?

Fugu replaces a couple of the lower level processes with a version from a newer version of Android. The current version of Fugu uses binaries from Ice Cream Sandwich. They're reported to increase overal responsiveness. I had decent luck with earlier releases, but I haven't tried the latest.
Loopy Smoothness elevates the priority of the launcher while it's in the foreground so that, in theory, it is more responsive. In practice, the results are mixed and it depends a lot on your individual setup. It requires some extra setup on the user's part as well to make sure that your launcher is being watched.
V6 Supercharger is an overhaul to the memory management system. Specifically, it modifies the way the built out of memory task killer system works. It's not a task killer on it's own, and it doesn't subvert the Android way, but it tweaks some things and modifies the points at which the OS kills processes to free memory. It also raises the OOM priority of the launcher so that it becomes a last-resort kill (to prevent redraws). This one is really, really mixed and really depends on a lot of factors. You can make things run really well with this, or you can make thing run really badly with it. It pays to do some research and understand exactly what it's doing to the system if you intend to run it. It is generally unecessary, especially on the GB builds, but with some tweaking, you can get some good out of it.
TL;DR Ramexpander set at 4gb swap file makes all the difference for this tablet
A little background: I've been modifying my phones since the galaxy nexus. I've tried greenify, amplify, debloating, kernels, overclocking, cleaning, l-speed, etc. I like to run a lot of apps, and all of my phones and devices, including the Nexus 6p (until the Pixel XL) lagged. RamExpander has been the solution every time, and the fire hd is no different. This one: https://play.google.com/store/apps/details?id=com.swapit.expander.de&hl=en .
Use the free version here to check if your device is compatible: https://play.google.com/store/apps/details?id=com.roehsoft.meminfo&hl=en but I know a rooted 2017 Hd 10 running 5.6 is compatible.
Maybe your device runs perfectly already and/or you're using less apps. That's great! But I have seen a few threads about trying to optimize performance. IF your device lags, this app will make an immediate night and day difference.
I'll give it a try
I have L Speed and Greenify installed on all of my rooted Android devices. Could you please explain to us how RAMEXPANDER is better than L Speed/Greenify? I'm curious. I'll do anything to optimize these Fire HDs even more. I rooted them and installed Google everything on them so my parents don't have to deal with the Fire OS.
Is Ram Expander really worth $10? I wanted to try it and found an APK. The damned thing was contaminated with neverending ads appearing every 10 seconds... I had to uninstall and run Malwarebytes to get the tablet working fine again. I assume the "real" paid version has no crappy ads?

I know Greenify already and use it on my tablets and cell phones. But it's the 1st time ever I hear about L Speed. Is it complicated to set up?
The 2GB memory is pretty limited, and disabling some Amazon services and avoiding apps that remain persistent in memory is highly recommended. I installed the official Google app to get Google Assistant, but found that it used too much ram. I recommended installing system monitor and monitoring the active processes, sorted by ram usage, to identify bloated user apps.

so what ram expander does is it's just a super easy way to setup a swap file (space on the internal sd card that will be used as RAM). Why is it better than all the other stuff I've tried? It's empirical, not logical. That is to say, every phone that's lagged, if RAMEXPANDER is compatible, I've installed and it's made a huge difference in performance, every single time. I've messed around with a lot of optimization tools beforehand and results have been mixed. I can improve battery life usually, but the phone will still lag, with those tools and with all the apps i run. Also, each tool is just more strain on the system.

I've never seen an add in the app. You got a bad APK.
An alternative, I've found, though less intuitive is an app called apps2sd. https://play.google.com/store/apps/details?id=in.co.pricealert.apps2sd&hl=en
It's a little less intuitive, but basically when you open the app, you get a bunch of tools to choose from. If you choose the SWAP menu, you can create a SWAP Partition on the /data partition. 4gb has been working amazingly for me. Then go to settings and check the "apply swap on boot" (after you test it for a while, and you're happy and everything's stable).
L-speed has a lot of options. It's got a few profiles, but I'm not sure that they actually work. With some messing around you can get a little improvement here and there (or maybe it's placebo). Sometimes an update of L-speed will bootloop your device, but I only use it on devices I have an nandroid ready to go on.
SWAP, through ram expander or apps2sd, makes a night and day difference compared to any other tool I've tried.
Does Ram Expander starts automatically at each reboot or it has to be started manually each time?

I keep trying to install this (the Google Play store version of ROEHSOFT RAM Expander) on a Fire HD10 with root via Kingoroot. I'm trying to install the swap disk on the SD card, and I'm getting an error message:
You have a Limited Kernel
Kernel Swapspace Limit detected! please reduce the Swapfile Size lower 1GB! and try again!
This happens no matter what size I pick for the swap file on the SD card.
If I try to use the same company's "test" app (MemoryInfo-SwapCheck), I get this error message:
Path Error
This Path is not usable for Swap!
I can verify that both apps are successfully creating the swap file on the SD card (swapfile.swp or swaptestf.swp, depending on which app I'm using).
I've tried both systems 5.5.0.0 and 5.6.0.1 and I get the same error message on either. I've tried installing it on a completely fresh install of both, with only Kingoroot, SuperSU, Google Play, and RAM Expander installed (in that order). I've also tried swapping out SD cards, and get the same error on both.
This software does work properly if I install the swap file on internal memory, but I'd prefer not to do that, since I can't replace the internal memory if I wear it out.
The weird thing is, I could swear it was working properly before (a couple of weeks ago), but nothing is getting this to work now. It's possible I was mistaken and had accidentally chosen the internal memory, but I don't think so.
Anyone have any clue about what's going on?

For some reason, this software doesn't work if you set the path to /storage/sdcard1 (It will create the swap file, but then it gives the error message I described).
Instead, you have to use:
/mnt/media_rw/sdcard1
Then it works totally fine.
Also, if it's useful (and saves anyone else time), here are the values that each option of this software generates on the HD10:
multitasking
SwpFile = 3000MB
Swappiness = 100
MinFreeKB = 54MB
DriveCache(KB) = 4096
balanced
SwpFile = 3000MB
Swappiness = 100
MinFreeKB = 62MB
DriveCache(KB) = 8192
gamers
SwpFile = 3000MB
Swappiness = 100
MinFreeKB = 62MB
DriveCache(KB) = 16384
net gamers
SwpFile = 3000MB
Swappiness = 100
MinFreeKB = 4MB
DriveCache(KB) = 1024
I have no idea what those options mean or do, but I went with "balanced" (since it seemed pretty middle of the road) but with SwpFile set to 4000MB instead of 3000MB.
Ramexpander etc.
I've paid for and been using RAMExpander for awhile now. It's a good app, and worth the money. That being said, App2SD is also an incredibly useful app, Pro or no. L-Speed is great as well. One thing to note, from what I've researched, editing your zram is also helpful as it compresses items in memory to free up space, and it is prioritized over Swap. Using the two in conjunction (having a zram file (250-500 MB seems to do the trick but you could probably go lower) and a decent sized swap file(mine is 8GB but I suspect this is massive overkill and 4 would work)) has left me with little to no lag, especially when paired with L-Speed's other exceptional tweaks. Jade Empire and Kotor run with 0 lag at top graphical settings.
Hope this helped clear up any questions.
Edit: If you use App2SD's partition manager you can set yourself up with a partition dedicated exclusively to Swap, then in Ramexpander change swap location to this partition in the settings. Ramexpander tops you out at 4GB, doing this is a good way to increase that threshold.

so what ram expander does is it's just a super easy way to setup a swap file (space on the internal sd card that will be used as RAM). Why is it better than all the other stuff I've tried? It's empirical, not logical. That is to say, every phone that's lagged, if RAMEXPANDER is compatible, I've installed and it's made a huge difference in performance, every single time. I've messed around with a lot of optimization tools beforehand and results have been mixed. I can improve battery life usually, but the phone will still lag, with those tools and with all the apps i run. Also, each tool is just more strain on the system.
I've never seen an add in the app. You got a bad APK.
An alternative, I've found, though less intuitive is an app called apps2sd. https://play.google.com/store/apps/details?id=in.co.pricealert.apps2sd&hl=en
It's a little less intuitive, but basically when you open the app, you get a bunch of tools to choose from. If you choose the SWAP menu, you can create a SWAP Partition on the /data partition. 4gb has been working amazingly for me. Then go to settings and check the "apply swap on boot" (after you test it for a while, and you're happy and everything's stable).
L-speed has a lot of options. It's got a few profiles, but I'm not sure that they actually work. With some messing around you can get a little improvement here and there (or maybe it's placebo). Sometimes an update of L-speed will bootloop your device, but I only use it on devices I have an nandroid ready to go on.
SWAP, through ram expander or apps2sd, makes a night and day difference compared to any other tool I've tried.

How did you set it up?
I swaped it on Sd card on my j7 & it became to freeze & became super slow...
What about using BK Disabler?

Just out of curiosity, what are your L Speed settings?
I went with App2SD and L-Speed after reading this thread, and wow, it's practically a different experience, a different tablet. If you aren't doing something similar you're purposefully using a tablet that is gimped.
Here are the settings I went with:
App2SD swap is set to 4GB and placed in /data.
L-Speed has everything turned on as it would when first installed.
RAM Manager is set to balanced, seems like more than enough and I don't want to be plugged in frequently.
zRAM Optimization is set to on.
I then went back to swap settings and set the zRAM to priority 0 and /data set to 1.
Turned improved scrolling on.
Everything else was left as is, for now.
I can't believe this is the same tablet I was using a week ago.
No need for Greenify with this combination.
What size should i set the swap partition to?
Since the swap will be on the sd card, should I go with the Samsung MicroSDXC EVO Plus which has 100/60 read/write rates or the Samsung PRO Endurance which has better reliability (designed for continuous writes) in the long run but only 100/30 read/write?

You could probably get away with 2GB, honestly. In which case, I'd really suggest putting it on internal in /data.
Just one less I/O delay (even if seemingly trivial, will cause lag) to deal with.
If you're going with putting the swap on an SD rather than internal, definitely the fastest SD you can use. :fingers-crossed:
If you must put it on the SD, at the least create a zram "swap" on internal, it only has to be ~150-300MB.
Hello XDA S7 users
So I was hoping for a performance change in Oreo but it's just the same nougat.
We have 4 GB ram and we don't need virtual compressed swap partition in RAM. This was useful in Old android days when devices had 1 Gb ram and that stuff, and I wanted to go swapless. I found this by simple Googling. It's a simple, small magisk module that removes the swap partition from RAM making it all available for the applications. Also to make use from Swap as on Linux desktops Swap should be 2X the size of the ram and not compressed as compression takes from the CPU power.. but this is not the case here, it is actually part of the RAM lol, and it's compressed
By installing the module you
- make all RAM available to the user and apps without virtual disks inside RAM
- preserve CPU as all the time the cpu is compressing and decompressing data to and from the Swap partition. Preserving the CPU gives you a performance boost as more CPU cycles are now available for user.
- Preserves battery by using less CPU power.
This was evident when I used it on the latest Oreo leak ERD2 and now my battery lasts +24 hours and the phone is very fuc*** faster. Apps open instantly and multitasking is way better 'comparable to iPhone' . I even increased animation factor as with default value animations were so fast
The module zip in the devs thread, download and flash in Magisk then reboot.
This module was developed by the talented dev @EarlyMon if this helped consider donating to him, check his thread: https://forum.xda-developers.com/apps/magisk/module-swap-torpedo-run-faster-reliably-t3766883
My setup:
Rom: [OREO][SE9][ERCB][01/04/2018] Galaxy S7 Edge - Oreo DevBase
Using the rom's kernel with Magisk 16.0 and Viper4android. Didn't try with Xposed.
My battery usage is attached too.
Is working for nougat?

Try it on oreo.
applied on my Nougat, lets see how much juice I can get, thanks
Superman 2.9 stock settings. After applying the mod phone freezes very often, returns back to life after few seconds. this happens regularly at no apparent time.
On note 8 port,
Causes freezing , FC of Touchwiz, camera wont start up as well.
Tried a different launcher , same problems.
Please post your oreo set up, like rom etc...
Check the post I added my setup.
Following up frpm previous post.
There are definitely issues the longer you use it.
Seems like the more times you restart the heavier the stutter.
Seems like the zram is necessary because it is taxing on the processor.
My home key and power button disabled themselves after about 2 minutes after booting and even booted into download mode by itself until i uninstalled the module.
Too bad for those of you experiencing trouble, I wish it weren't so.
Zram (or Samsung's vnswap) is MORE taxing on the processor, not less.
But the additional swap does allow more bloat to be crowded into ram while swapping out essential functions for fast reloading. (Why anyone would build an Android where essential functions COULD be unloaded escapes me but it is what it is.)
There are no lingering effects to the module and it runs one functional command at startup - nothing extra runs after boot, less runs. The Swap Torpedo isn't a new tactic, just a new method that takes advantage of the systemless modification for startup thanks to Magisk.
Sorry to those that are having problems with it - thanks for trying it, and definitely uninstall it. Life is too short for a broken phone!
Also consider trying it with your next update, rom, or phone. The majority of Samsung user feedback has been overwhelmingly positive.

I tried with new S9 rom, it works best when I made internal storage swap, I have totally uncompressed 4 GB ram thanks to your module and 2 GB uncompressed swap on internel flash memory. I still find it a good move and it worked flawlessly with my other HTC phone.
Lol.. Pretty nice tho.. But showing the 4h sot isnt making it incredible.
I get 5h sot on superman 2.9 with normal use (youtube, games, music, texting, snapchat).
I am interested in the non-lag thing. Will try it, thnx man
do u use your phone ?
Does i need the module?
Sorry to disappoint you with my comment:
1st - 24 hours you are getting is probably because you don't use your phone at all ! same usage with a good Kernel should get you 2 days at least.
2nd - Samsung galaxy S7 Edge does not need any Ram management I mean come on it's a 4Go, there is a Ram cleaning tool already included in Device maintenance.
finally - After trying this module all I got was : performance decreased and weird UI behavior.
Do you really want a great battery and performance? go and try Devbase ROM + MoroKernel and you'll thank me later
