Android 5.*.* Memory Leak Official Thread (Advanced users only) - Nexus 5 General

*Note to moderators: Please do not close this thread, I am aware that there is already thread called "Anroid 5.1.1 memory leak still present. Incredible!" but this thread will focus on solving this issue as quick as possible and getting attention of highly good developers and people which can give information for solving this issue ASAP
This thread will be official thread for all Nexus 5 advanced (developers) users which got affected by this issue.
First of all please do not spam and post useless information about how you also have memory leak and asking how to fix it. Post only useful stuff, like logcat and such stuff which can help google developers solve this annoying bug.
I reported this issue to google with good amount of information and I am willing to keep that report updated with latest highly detailed information, link:
https://code.google.com/p/android/issues/detail?id=171150&thanks=171150&ts=1430506443
Please star this so we can get quick attention from google and assign it as high priority bug. You can star it by clicking on star top-left on the page.
- For users which seem not to have this issue please Download Farm Heroes Saga from play store. Run it until game loads, then remove it from multitasking menu completely and then run game until it loads, remove it from multitasking menu again and do that about 10-15 times. If your ram doesn't go up to 900 and higher please post logcat if you know how to and also screenshot of default memory and cached memory.

Please everyone who voted no, try this out and send me a message if your ram went nuts:

Update- I contacted King, company which made farm heroes saga, game which is causing memory leak. Maybe they can help solving this issue

If this is only happening with one piece of software, that means it's down to the software not Android

It's is certainly not only farm heroes. I got memory leak even without running farm heroes

What else is there? it seems a lot of people confuse memory leaking with RAM caching, RAM is much faster than eMMC therefore it's cached to RAM.
I'm personally not seeing a leak with 5.1.1
Not to the degree of 5.1 which does have a leak, Applications can leak memory too.

I installed CM 12.1 latest nightly CAF and AOSP and tried doing farm heroes saga method. My ram went to 1.4 by repeating it 10 times. And also by using phone 3-4 days, system memory goes up to 1 GB and I'm not talking about cached memory

But the OS is at fault for not clearing that memory allocation it uses for X app when it's long gone and not in use/closed.

Have anyone tried to hunt memory leaks with kmemleak? I would do that if I had enough time, maybe next week.

[Q] Full RAM after using a some apps... with a little analysis

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.
Too cluttered.
Thanks

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.

The phone does have 512mb of ram. It just isn't used properly.

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.

Nah, all phones advertise the actual chip size in it, not the amount the system actually lets you use.

[Q] Extremely Low Ram & Camera Force Closes - CM7

I have a Droid A855 rooted, CM7 installed. I have the latest build. I have two issues, one is that the free RAM is ridiculously low with like 5 apps open it has about 20MB of RAM free. This is unacceptable because my Huawei Ascend has 90 free with many apps open, and the Droid has twice the ram of the Ascend. Is there any suggestions about this? Also the camera was working great and then it started freezing, and now the camera force closes when I press the button to take a picture. If I go to the camcorder it works fine, but otherwise I get force close. Any help would be greatly appreciated.

Personally CM7 has just never ran smooth. No matter what I have tried. Gingerbread was never really meant for the Droid so most roms have built in stuff to help with memory that I do not believe CM7 ever had added. and the camera is outright terrible lately, I have it force closing on all my roms. I really don't know how to help all I can really try suggesting is trying out other roms

Thanks for the quick reply, I beg to differ on the Gingerbread not being for the droid part, my old Ascend runs Gingerbread Cm7 with flying colors, and this droid has double the performance...

I think you guys are missing a crucial part about how Android is built. Free RAM is wasted RAM.
Newer versions of Android, especially Gingerbread, are better at RAM management than older versions. Granted, there's an ever-growing need for more RAM for basic system functions, but Android is designed to free up RAM on-demand for the things that need it.
Just because RAM isn't free doesn't mean that the system is going to slow down. Android will put the stuff that's not being used anymore into a swap file so that the stuff you need to work with can do what it wants.

Yes but the ram is going so low that it is closing my applications like music when I go to a different screen.. it's frustrating

What? I dont understand

I agree with you and I will like to agree with you but it just won't work. This is like Windows Vista, they use all the memory, but it is very slow when you try to open application which you don't use a lot.. and it also causes a lot of slowness when you try to use more ram for soemthing else, like modify a huge image in photoshop and then switch to some other application.
Get back to the real story, my phone get memory lower than 50 free MB easily. and when I open Google current in this stage, it just hangs for 5 minutes. then I get a message "force closed". However, if I have 100 free MB, then I am safe, I don't see that popup message. Moreover, when I go to 40 free MB, I even have hard time to open skype and pick up the phone, it just rings, but the screen just hangs! when the screen refresh back, people get into mailbox already....
anyway, I found a software to temp solve this problem ZDbox. I set up when the screen hangs, "kill all apps in the memory" it is not best, but at least I can pick calls, I can run application without getting "force closed" message all the time.. because I need to reboot few times a day to solve ram issue.
perhaps, you can do a test yourself.
- install CM7
- install facebook app and run
- install google reader and run
- install google current and run
- install skype and run
- install gmail and run
- install google voice serach and run
- install google book and run
- install whatsapp and run
- install naver LINE and run
- install twitter and run
- install zdbox and run
- install lookout and run
- install go laucher
well after all this, your phone show be in less than free 50MB.. if so, try to run other application and you will see the problem.. screen hangs.....very slow response....not able to pick calls...

Yeah but even though "free ram is wasted ram" it still causes instability and force closes along with just pure out lag. My D1 lags when it has only 30mb of ram or less anything over 50 and it flies along. It lags to the point were even simple tasks are slow when they should not be.

Droid has 256MB RAM. (Actually, there's only 226MB RAM available to kernel.)
If the Droid has twice the RAM of your Huawei Ascend, then your Ascend has only 128MB RAM.
If it has 90MB RAM free with many apps open, then it means that all the system services and all the "many" open apps has to fit to 38MB of RAM.
That's hard to believe.
And btw., you can't compare RAM consumption on devices with different display resolution. Droid drives 854x480 pixels and uses hdpi bitmaps. I guess that the Ascend has lower resolution. The RAM demand is much higher on WVGA hdpi devices compared to low resolution HVGA/QVGA mdpi/ldpi devices.

When I my HTC Desire Z, I was in love, awe of the beautiful interface HTC Sense and the many adjustments I needed to make experience to a higher level, the Android. However, as I went about installing my wealth of applications, games and widgets (more than a hundred, are addictive), Sense started getting so instead of improving my experience. The initial screen would start every few hours re; each faucet took longer to record; Screen rotation when the keyboard sliding open continue for centuries; and each phone looked like he was struggling to get by.

[Q] memory usage

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.

in this case, i cannot access on other apps that i'll run. just manually kill all the apps every-now-and-then.

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.
