After fixing some lags with I/O system by using filesystem LagFix I still have a Lag problem in my system and I think it's not related to Samsung.
I think this could be an Android problem.
After a fresh reboot I get 124MB of free RAM.
BUT... every day I need to reboot the phone because after 3 hours it became laggy.
Now I analysed this and read a bit about the memory management on several forums and was able to reproduce the lag 2minutes after reboot.
I just need to use much applications one after another to raise the RAM usage for every application.
When the free RAM reaches 40MB I think the system clears some pieces for using it for the app I now want to use and there is the LAG.
Is there any fix for Android not caching every activity of an application in the RAM?
Now for me Android feels like: Usage -> Full RAM -> Lag
Sorry for the new thread but after 2 hours of research I didn't find anything useful over search function.
Yea, every program should have as much ram available as their size. 2gig for program storage on sgs, so there should be the same amount of ram ;D Anyway, theres still less memory for programs on the sgs than for example in the N1. I'd say there is about 384MB of ram total on the sgs and not the 512 claimed.

Not just the RAM for the apps... there's much more...all mails from internet, all google talk conversations, the wather I checked out from internet with any widget, feels like every interaction is cached into the RAM until it reaches the 40mb mark and after that every interaction on my system is laggy... for example: opening the notification bar needs 2-3 seconds.
I already talked to N1 users with the same problem

Heading out the door in a minute so can't comment on the rest, but I strongly disagree with that part of your statement.
As an N1 owner I've NEVER seen lag like I suffer on the SGS. Never seen the absolute FREEZE in the GUI like the SGS gets.
I'm running FroYo on the N1 now, so can't compare side-by-side to the SGS things like memory usage, but I don't think that's the issue here if you're going to use the N1 as a comparison, despite other users complaining of lag.
You might try Autokiller or the free memory manager app from the Market and see if that improves thing, they'll keep more or less memory free depending on settings. You could test how soon lag comes with default, minimal, and aggressive settings.
I never testet Froyo because everyone said, it's unstable but for me it seems like froyo has other RAM management than Eclair when you said you can't reproduce this problem.
I'm already using a task killer... I have my main apps ignored or excluded and most time there are 2 or 3 apps which will be killed after lock or time or what else.
What's the problem here... if I would use a PC with 512MB RAM and use only 10 small applications, it won't cache everything in the ram until it's full.
Hi, didn't read all the posts, but u should look into the RFS file system, which is samsung proprietery file system. It has a very bad implementation on android (i could be wrong). As for ram, the phone has 512 mb, but 128 are reserved for Gsm/data connection. Just think if you had an incoming call and all your ram was in use, u had to wait for the system to clear up some memory before being able to receive the call physiclly. That would be a long wait.
I could be wrong and sorry for the bad english.

Have you ever tried "Minfreemanager" app?
It can change the minimum available memory level in different app usage.
The device must be rooted first.
Then select "Aggressive" preset and see the result.

DAMN!!! Nice app... it does exactly what I need cleans my RAM so I'll get 120MB and after that loading of apps is much faster than starting apps with Android included RAM cleaning.
It just cleans my RAM like a reboot but without the reboot
This should be a temporary solution until someone finds a better solution or until froyo is released.
I would like to have an application like this with an autoclean option on 2 hours
Guys please,
Getting off-topic here. Here is Android Development.
Not Q&A or General.
Please post in the right section.
Here is getting too many off-topics that pose no relation to Android Development.

Auto killer is better.Its exactly the same as minfreemanager but can be made to apply at boot.Minfree manager resets itself at boot.
I use Memory Booster Lite (free version) app to free up memory, must do that manually but it works very well, if you buy the app it free up memory automaticly.

No, wrong. The reserved ram is in the form of a ram disk, which seems to be a bit oversized. Not really sure why a ram disk is needed at all, personally.

This is the correct solution. the JF* series of firmwares have very bad default settings for killing unused apps. Use this app to set them a bit better and you shouldn't have any problems.

It does have 512 of ram, but some is partitioned off for the phone, so that you can always receive phone calls. Just about every device does this, because users would be more upset if they couldn't pick up the phone until they had closed a bundle of running programs. Don't you think that people here would have noticed earlier if the SGS physically had less ram than claimed ?
As far as the OP is concerned, sounds like you are just running too many programs at once. Its not an android problem, its user error.
Any task manager, but particularly an auto-killer will set you right, although alternatively you could try not leaving every app open when you're finished with it. You think your PC would run ok if you left one game open while you opened another ?

I wasn't comparing a N1 on FroYo to the SGS on Eclair. My comments were in regard to when I was on Eclair, which was several months...FroYo's only been available for a couple of months. What I said was since I'm on FroYo now, I can't compare side-by-side, but my experience with an N1 on Eclair was never any lag problem or GUI freezes.
Anyways, I also suggested you try Autokiller, and you missed that or misunderstood it by saying you already run a Task Killer (which is generally considered a bad idea, but I see you picked up on Autokiller after someone else suggested it. Enjoy.

There seems to be several things causing this, but the two key issues are:
The moviNAND (the internal flash drive/"SSD") firmware seems to have an issue with fsync() taking extremely long. E.g., it slows down whenever a file is written/updated on the internal storage.
RFS, the file system used by Samsung is buggy as hell and corrupts data after a while.
There are several topics on these issues in the Android Development forum. There are also several "lag fixes" trying their best to overcome these issues. Go check them out

We have no idea if that is ACTUALLY true.. Just because fsck picked some things up on 1 phone, doesn't mean it happens everywhere.. Furthermore, it doesn't mean the problems detected affect operations
that has no truth at all about more apps slowing down the phone, my phone is the prove
Before jpk i didn't noticed slowdowns with aprox 100 apps, now i do on jpk =/

With autokiller the phone is still laggy.

AFAIK this topic and its responses are for the OP
I have about 190 Apps installed and do not experience any diferene in overall speed of the phone. But only because i know that a lot of the programms start on boot and stay in background.
I have more than 15 apps turned off with the full version of autorun killer to prevent the auto restart of the apps. Otherwise the phone would definetaly slow down.
It´s really incredible what apps start on the boot!

Do you need to be rooted ti use all of the functions in autorun killer? I am not rooted.
Can you compile a breif list of the "biggest culprits" to stop with this utility to gain back the most speed and efficiency? I am a bit nervous that I will stop the wrong items and somehow damage my phone...
Autokiller and task killers are not the solution here! Quick lesson on Android, and why having even A SINGLE BAD APP is going to ruin your whole phone!
Android has something called an 'Intent'. In order to start an app, an intent is made by your launcher or a button you press, and the Android system reads this intent and works out what app it needs to start up.
There is a second type of intent though, called a 'Broadcast Intent'. This is an intent that is sent out to anything that is registered to listen to it. This means that an app can register to listen to all sorts of events, such as battery level changed, application start, or a tons of other things. Even if the application is closed, if it is registered as a listener, Android will start it right back up so it can deal with the intent. If the intent comes every 5 seconds, Android will run this app every 5 seconds even if you have a taskkiller killing the app.
The only real solution is to not install apps which are bad! Finding bad apps is a real mission, too. Hopefully in the future, utilities will be available to let us track down these terrible apps, but till then, you'll have to work it out yourself.

No need for Root to use all features of Autorun Killer. I would disable only the apps you know and which you do not need at startup and running in background, such as (in my case) Paypal, App Center from Androidpit, Daily Briefing, Photoshop Express, Word Press, TweetCaster, etc.
Every of these apps works normal, even when deactivatet on startup.
So unless you do not disable system apps (must be previously set enabled in settings) you are safe.

There is an app called Autostarts at 0.95$.
It shows what is launched au startup, when you enable/disable wifi etc.
It think it gives insight on how apps seems launching out of nowhere.
I also reccomend Watchdog Task Manager Lite, the free version.
It does not kill anything, but notifies and logs the bad apps that consumes over a certain CPU percentage.
Hello!
Welcome all galaxy s and android owners Im quite new to this hardware and software, in fact i spent all weekend trying to understand this machine...
Eventually, i fixed 3-combo bug, updated android from 2.1 to 2.2.1 JPU and applied speedMod from here:
http://forum.xda-developers.com/showthread.php?t=822756
And im wondering, do i really have so much ram? I have system info widget, it shows only about 150-190, on android 2.1 it was about 120-160, everything looks like my galaxy s has only 256 MB of memory (i just cant believe that) :O How can i check it more accurately?
Hey mate,
The reason why you can only see 339mb (or there abouts) of ram free is because the OS reserves some space for critical system apps.. Imagine if you couldn't receive calls because your live wallpaper and that game you are playing was using up all your ram.
Hope this answers your question,
Alex

By right our phone has 512MB.
However, some of the memory needs to be use for critical applications (e.g. running the phone etc.) therefore we are not able to unlock all 512mb for our use.
What you are able to see (since you're using SpeedMod kernel, it will be 339MB) is the memory available for OUR use. Do note that our phone needs to use part of that 339MB RAM to load up applications/boot up therefore you would not get 339MB free (rather about 120MB free ++ out of 339)

Actually, that's a common assumption I hear which gets thrown around here but has never actually been proven. Apparently it's a memory hole, which means devices are using it. If it were reserved for apps, it would probably still show up in total RAM. Remember, Android is smart enough to kill apps as needed when more ram is required. Furthermore, freeing RAM doesn't take much work. So this explanation doesn't make much sense imho.
The reality might actually be that Samsung haven't had time to dynamically allocate the space with their drivers, so they took a shortcut until they had time to optimise.
Regardless of amounts I can say that 2.2.1 is the first firmware where memory management does not appear to be an issue.
Ok i found out that i actually have 339 Mb of memory. The problem is that all the time at least 130 mb are in use. I think that all the stand by android and samsung apps should work on the memory that stands in 512-339 and it shouldnt take my memory space. I saw 339 in task manager, also over there i see that samsung "steals" from it about 130. In addition it process running i see only about 30/40 memory in use. Android takes 16 mb. Any1 can explain this to me?
my phone showing only 304MO of RAM. Why?
Read what i did. U dont have speedmod. But what about my 130 lost memory...
Good day!
Im new to xda-developers forum, just found a link in youtube while watching some stuff about galaxy note.
I have not discovered my galaxy note thoroughly yet coz its still new to me. Just wondering, the usage of memory without running any apps will go about 60%-70% percent. My temporary solution for this is to run task application and kill all exciting apps. Just wanna ask what kind of problem this may be?
No need to get alarmed by that. That's the way Android runs: it keeps apps in cache, so you can access them faster. When there's too much of them cached, the system kills off some apps.

the only thing is, when i access on other apps like games. loading on the apps takes longer or even it crashes. maybe its because of the memory allocation of the apps or just there is no enough memory space to allocate the app.

While what the other member said is true, unused memory is wasted memory, but the issue is exactly that. Android ends apps that you may be running to be able to open more apps, which I find bad.
While it is normal to find the amount of ram you have said already loaded and being used, I still don't like it.
There are times that I'm trying to multitask and I open an app and right away jump back into the previous app to find that Android OS has decided to close it, within 3 seconds of hitting the home button. It makes multitasking a little harder. But there are ways around this .
But still, I hope ICS fixes this issue. I don't need 200 of the 1 gig of ram in use, what I would like is to have 300 or so free to be able to multitask normally.

can you please elaborate on the workarounds so that Android doesn't kill the background apps especially opera mobile
Just a thought about memory utilization....
So Oneplus 3 is the first mainstream (not the first overall) android phone with 6Gb. Apparently all that memory is not currently utilized. Most likely it is not fully utilized even on 4Gb phones. There is really no point in wasted RAM. Having a lot of open apps in memory is truly great and could be the best use for it, but it also can present some issues. Background apps on android are not always suspended in the best way and can waste resources (CPU, battery). Of course if app and system are optimized correctly this shouldn't happen, but unfortunately it is not always the case. While google optimizes the system with dose features etc, I'm wondering about a simpler option until the better one is built into the system.
RAM is 10 times faster than storage, so why not use a portion of it as a RAMDISK, like in old days (MS DOS times). For those who don't know, RAMDISK is a portion of RAM that is used as a temporary storage (like flash memory), that will be 10 times faster than permanent flash storage.
Basically out of 6Gb RAM that phone has (Oneplus 3), 3Gb would be used as regular RAM and 3GB would be used as a RAMDISK. RAMDISK completely looses all the data after reboot, but the good thing is that phones don't really need to be restarted often. So RAMDISK would be almost permanent. Lets say you have 100 apps on your phone. Out of those you use 30 all the time. It is a bit inconvenient when app that you use often (for example Facebook) is kicked out from the memory and has to reload from flash storage (slow). Instead you could have those 30 apps to be loaded/copied/synchronized to the RAMDISK during initial boot. If app is kicked from regular RAM and needs to be restarted/resumed it would load 10 times faster from the RAMDISK. During regular intervals and before reboot data/cache from RAMDISK can be permanently saved (synchronized) back to the flash storage. If you have your favorite app that keeps misbehaving in the background (uses too much CPU, doesn't let phone to go into deep sleep and kills battery) you can just have it removed from background processes (swipe away, greenify, kill it etc), but then it will be almost instantly reloaded from RAMDISK when you need it later. So in the end you would have all your favorite apps loading super fast, even if it is not currently running in the background. You would sacrifice some RAM for faster app loading, possibly also minimizing battery loss due to some bad apps.
My knowledge of Android system is very limited and I might be very mistaken regarding this option, it's implementation and benefits. I would love to hear what people with better knowledge can say on this topic.

It is not about fixing the number of apps that can be held in memory, it is about different use for the RAM. When you have 40 apps in the background some of them can kill the battery. That is probably why Oneplus limited the number of apps. RAMDISK could potentiality minimize the battery wasted by background apps (if they are not suspended correctly) by removing them from active memory and still allow fast restart when needed.

RAMDISK could potentiality minimize the battery wasted by background apps (if they are not suspended correctly) by removing them from active memory and still allow fast restart when needed.

Android can not address any RAMDISK, it just makes no sense here.

Look at the amount of free RAM in average use. There will be plenty that is unused. Keeping lots of apps cached is the best use for the free ram, but in some cases those background apps need to be removed from the active memory to prevent app from keeping device awake (and killing battery as a result). For example RAMDISK would allow to greenify all the bad written apps, stopping them from draining the battery, but then reloading them back to the active RAM almost instantly (much faster than from flash storage), when user wants to access the app again.
This situation (RAM "waste") can sure change with advances in android system itself, but as of now I just think RAMDISK is not a bad option for new devices with a lot of RAM onboard. Apparently we will see android phones with 8Gb Ram pretty soon.

There is no such thing currently, but it doesn't mean that it cannot be created (at least in my understanding) and implemented via kernel or just an application (background service).
Here is info from WiKi

Here are the examples of programs/apps for PC:

Plenty more can be found online.
I remember we used to do that on the HD2 - it was pretty cool!

Pity it was just Windows Mobile OS.

The impression i got that was not all that ram was not available and was reserved for the system. To the point one questioned that 6GB was available, felt like less.
How much RAM does the OP3 mention as free after a restart ?

It shows about 4.5Gb free. I'm yet to fully test OP3 and see my average memory usage, but I doubt that I will have less than 2Gb free

4.5GB free implies its working as stated.
You're saying in use that memory gets reserved and drops, that is more than it should.
Do u have any ideas how can that be done?

As far as I know, there is no RAMDISK app for android at this time. I would love try it out myself. Unfortunately I don't have much coding experience to create this app (or kernel).
On a side note, after more time with a 6Gb phone I can see that this RAM can get utilized quite a bit. After editing the build.prop to magical number 42 and running bunch of apps (regular operation, nothing really extreme), the free cache reported by OS (developer options) is 1.2GB - 1.3GB. at the same time in RUNNING SERVICES it shows 2.8GB free. SYSTEM got bloated to 2.0GB
From what I can see, the apps that I use didn't misbehave so far and even with such heavy load on RAM, my battery didn't take a hit. As a matter of fact I'm very surprised by battery performance so far, but I'm only 1/4 way through.
That being said, I would still love to create 2Gb RAMDISK from that 6GB and play with it more.
Man your battery life is really good!

Actually, my RAM is well used and i am grateful for having 6 GB in the phone, that is, because i am using two profiles and on 4GB phones they were always operating at the limit. with the oneplus 3 finally this is over.
Praise the lord.
Hello fellow MI5 users,
I received my phone one week ago and I start having some issues with the RAM. In fact, at the start of the phone, it's already at 70% filled up which is too much for me. Indeed I use a lot of RAM and I'm that type of guy who let the apps running in background everytime because I keep opening them everytime. I was wondering if it was possible to have a link to a better ROM because I guess it's the problem and also a link for a tutorial on how to flash it I'm a newbie in this type of manipulation but I'm very interested so I hope you will help me guys. By the way, my MIUI version is the MIUI 8 Global 6.8.18. I honestly don't know what can i give as information but I'll answer ASAP at any questions
Have a good day
This is working as design - Android keeps apps in RAM to reduce I/O on resuming from background - faster & more energy efficient.
You can change the number of background processes via the development settings or you can kill apps on closing.

I've seen that indeed but it was set at standard so I'll probably put it at 3 I guess. How should I set the memory optimization? I've read it should be set off, altough I tried middle and I feel comfortable like that?
Is it normal to start at 70% without anything started ?

For the 3GB version? Pretty much. MIUI is horrible.
After booting I typically had 1.3GB / 3.0GB free but after a while this averaged to around 650MB free.
free ram is useless ram , which cant accelerate anything

I know that but I need more because I use multi-task a lot. Is there a way to change the ROM so I have more space to work with? Even if the ROM itself is beautiful.
Indeed it's the 3gb version 32gb. It have lags sometimes and I think it's due to the full RAM. Can I have a link to a custom ROM which works fine on this device?
I'm a little confused, you want as much RAM available but you want as many processes in the background as well? That sounds contradicting to me. Memory optimization maps to ZRAM, if you set it off there will be no memory compression and thus even less processes will be kept in the background. If you set it high, you can have as many processes as possible, but there could be lag due to (de)compression time overhead.
Try different Rom
Try to use a different Rom. On the Stock Rom is a lot of bloatware which is using your RAM too.
First you need to get an Bootloader unlock permission and have to unlock the BL.
It could take up to 10 Days to get the permission from Xiaomi
http://forum.xda-developers.com/mi-5/how-to/unlocking-xiaomi-mi-5-bootloader-t3336243
After that you have to flash a recovery like trwp via ADB. Google it for videos or threads how to do it.
http://forum.xda-developers.com/mi-5/development/recovery-twrp-xiaomi-mi-5-t3412123
After that you can flash a developer Rom.
I use the Resurrection Remix and it works fine. The CM 13 stucks in Bootloop. Maybe because I made a full wipe and had to sideload my rom.
Because you don't have a SD card option you have to have the room installed on your hard drive. But just follow the description below
http://forum.xda-developers.com/mi-5/development/unofficial-resurrection-remix-m-5-6-9-t3395945
It took me just 1 day to get the unlock permit but don't try do do it without it. You brick your phone.
The RR Rom works really fine. Fingerprint and everything. It has no bloatware and you have to get the gaps like in the description. Arm64 nano seems enough.
Good luck and fun with a great phone.
Normally the android system kills the unused apps even in background. But i also experienced lack in multitasking.

I think you misunderstood the OP question, he wanted more free RAM at start in order to have as many as possible apps in the background.

Yup exactly
Try trwp 3.0.2.0 with 3.0.2.1 people experience bootloop

In fact, I'm just doing some research before asking because I'm very new. I have found some videos but they are pretty old and not on this phone but I guess it works more or less the same way

OK, in that case, just open Security->Permissions->Autostart and disable those which aren't immediately needed upon start. I have 18 autostart items (mostly system monitoring & social media apps) and I usually start with 1.5 GB free RAM.
