Nexus One Android OS Memory Leak??

I started off with around 280-290MB free on a fresh boot and after a while, the free memory drops to 200MB or so. Using taskkiller to kill all the processes yields the same result. I believe it's some sort of memory leak?

thats normal, i think, should be the cache usage, thats displayed there, if I know my linux'es. that memory will be freed automatically, when its needed.

Yep, FloOGB is right. Don't worry too much about the memory management, there's a lot going on under the hood and Android does a pretty good job. You shouldn't be alert when a lot of memory is used, in fact, you should be happy if most of the RAM is used.
I also suggest NOT using a task killer, you're battling Android's memory management by doing that and are likely to run into bugs because the auto-kill feature stopped a process that should have been kept running. E.g. someone had the problem that GMail wouldn't notify of incoming mail that has been pushed by the server. Turned out the task killer stopped a process required for the push mail system to work.

Sigh.
Everyone should post this video anytime someone complains about "free memory":

Please read the link above which explains Android's memory management. If you use applications like Memory Booster you will mess more with the phone then its good for.
We're not on Win95 anymore, guys, please!

A cache for each app installed gets created in dalvik cache partition & that takes the memory away !

I agree for the most part but I always keep a decent TK just for rogue apps. Everything stock/daily users I let android take care of anything new or memory intensive I kill like poorly designed apps or games... Works great... I love my n1

100% ack. some apps just need to be killed sometimes or some that stay resident and are not well written.
don't get me wrong, i'm not against taskkillers, if they are used in "manual" mode or to kill something specific. the problem are the "auto cleaners" that tell you that you need more free ram. the point is that you don't ideally less to no RAM should be free (not free in the sense of used for caching).
free ram is wasted ram.
my problem are the people who lure novice users to use these apps that may very well destabilize the phone.
@seventyfivein: why would one need to clear dalvik cache (if you don't update)? the cache has a reason to be there and the cache files will be recreated every time. if you remove an app so will be the cache file. i don't get the problem...

I use cache cleaner every once in a while... It seems to keep things snappy. Kill all buttons are silly

Try AutoKiller Memory Optimizer, it fine-tunes android system's inner memory manager routines (setting minfree values) resulting in a more smoothened UI experience without harming the system or running apps.

[Q] my galaxy is very very annoyed

I have no clue what happened....my galaxy was working fine...laggy a bit, but nothing i cant handle. I was at a club last night and recorded a 20 mins video...its saved. So as of this mornign my galaxy has been crawlingggg to load things....everything is either delayed or going really slow. NoLed is slow, chomp sms popup is slow....this phone is starting to commit suicide or something....any ideas why my phone started to all of a sudden lag alot?....when it didnt before???....and no lag fix is not a option for me.

Back up the video on your pc then delete it from the phone and see if that restores it back to its original speed.

yes i have and am now trasnferring the video...but Kies is taking sooooo long to do so. Its a real pain. I hope it was lagging cause of the massive amounts of videos i have...we shall see. (if i can get the video transferred)

if you're rooted you can try adjusting the minfree settings using the minfree app

This is what happened to my galaxy s as well. I have no recovery mode and root/lag fix was not an option for me till i found my solution step by step. I applied One click lag fix and it become so much smoother and faster. Sms notification has no delay even on Chomp Sms. =) The hardware of Galaxy S was good, but the firmware is a problem.

it seems ok now....(well not really )...but the reason i dont want to apply a lag fix is cause of the "reported" internal sd card fails....and i dont have $ for a new phone if this one gets screwed over.

i have auto killer and i just use stock task manager...as alot of people have been saying other task managers are useless cause Android OS is designed to handle it....confused....

the stock task manager is not that great, and the widget only works on the stock launcher.
the task manager the one i linked you can setup white list and black list
so it will automatically allow what to run, and kill what should not be running on its own

I wouldn't of used Kies to make the transfer, should've used a mass storage and transferred it using windows explorer. Also, I'd advocate against the task manager. I haven't used one on the SGS in about 2 months, back when I did I never let it run 24/7, sometimes I'd manually open it and kill almost all tasks. Task killers, such as ATK, will almost surely hurt your battery life if you let them run in the background, in fact, I'd even bet on it.
These days, I try to keep all my favorite programs in the background (unless they use CPU while idle, but even GTalk is great on battery life, as is LauncherPro and the widgets I have elected to keep). As long as you use the same 10-20 apps you should be fine, even if you use more you might be fine but not quite as good depending on how many apps you have loaded and storage space you use in total.
Since I highly doubt that the file size was huge and would overload the system, I wonder if a bug either sprang up and/or (maybe more likely) you created a hardware problem such as overheating your phone and processor and are now having issues. If nothing else works, try to back up all your apps and info to an SD card and then do a factory reset. If your problems continue then it's hardware.

Now I dont know whether to.keep the task apps or not lol...2 different opinions here...

The lagfixes don't increase the amount of writes to the internal SD and they certainly don't break it. Any of the lagfixes in the FAQ (see my sig) are well tested and nearly 100% safe. I would definitely recommend to either use voodoo or the modded version that uses the stock-kernel. You won't believe your eyes.
The reason your phone got so damn slow was because of RFS. The camera APP caches on the /data partition and when it does so, it created a massive amount of file system errors (a related thread can be found here).

So if i apply a lag fix...either OCLF or Voodoo...you can Guarantee i wont see a internal sd failure?...cause i remember All Gamer talking about how he wanted to fix the lag fix to write onto sd card or something like that...(dont quote me) its 100% safe?

Don't many developers etc say not to run task killers? They actually cause more drain on the phone and battery?
http://lifehacker.com/5650894/andro...ed-what-they-do-and-why-you-shouldnt-use-them
Note, however, that this is still a contested notion. A lot of developers (including ROM builder extraordinaire, Cyanogen) will not even look at your bug reports if you're using a task killer. In this humble blogger's opinion, your best bet is to stay away from regular task killer usage entirely.

i trust the hard fact results of the good it is doing in my phone, rather than some biased believes that just lags the phone if not actioned upon.

I dont know if I would call advice from well known developers as biased. Especially considering several others have shared this setiment. But what ever floats your boat. You are some what of a mr know it all here...
Sent from my GT-I9000M using XDA App

think about it logically, you do nothing to the phone and it lags like hell
or you can install legit software which easily lets you choose what to run and what not to run
result: system is squeaky clean and snappy fast
vs.
do nothing: system lags like hell, come to the forum complain the phone lags and claim other people are right we should do nothing and have an unusable phone.

Well the lag on my phone is minimal, it actually performs quite well. My phone died without any lag fixes etc, so I am not putting any of that on now. My problem is GPS is useless and the random shutdowns.

Custom 2.2.2

Took a break from porting 2.3 and threw together this themed 2.2.2
Its Gingerbread themed, a few graphical elements are missing though.

bout to give this a go

Do you have any screens to share?
Does this have djSteve's tweaks?

^ Posted a pic, and what tweaks?
Will post new rom with full info this weekend. Lots of new tweaks, additions, and subtractions.
Stay tuned.

Thank you streaker!

I agree on the lack of ROMs. I'm going to start to try to develop something simple (I'm self-teaching Java and Linux; what better way to learn than to tweak?).
I'll be downloading the Kitchen and playing with it in a couple of days's time, if not sooner. Since you offered, I'll ask for help when I get stuck!
Are you still working on a 2.3 ROM? Can a n008 offer any assistance? I really want to get my feet wet in development (apps or ROMs), so if I can be at all useful I will be.

idk if you are doing this, but it won't hurt to repeat it
make sure you wipe data/cache before you capture the cmw image this way you can avoid some issues for people flashing

I'll be flashing this in a sec, here. Gotta love more Streak 7 devs!
Did you make this in ROM Kitchen? If so, how did you go about it? I couldn't get ROM Kitchen to work on my S7.

Great to see some more developers! I'll definitely give this a go.

So I loaded it up and slapped on Zeam launcher; I have to say, it's pretty nice. This is basically vanilla, stock 2.2.2 with the bloat removed and a black bar (with some Gingerbread theme touches here and there). This is a great alternative to stock, and seems to run everything really smoothly. Nice mod!

Looking forward to the weekend version!
But quick question, if i go about flashing this, while in DJs HS7, do i have to return back to the stock then flash cwm then flash the rom?

Yes, you do. Unfortunately, there's not CWR for HC, yet (and, even if there were, I don't know that it would allow flashing FroYo ROMs).

Figured :S
I don't wanna risk destroying my internal memory

Installed and working perfectly. Im using vtl launcher. Very fast and works well!!! Thanks much and im looking forward to future releases.
Suggestions :
1) maybe a battery icon w / percentage
2) go launcher or vtl launcher
3) any cooked in file explorer
4) a modified wpa supplicant file to allow adhoc tethering
4) maybe a task killer. Im using autokiller memory optimizer and free mem stays near 150
Great work!!

FroYo has very good, built in task management. Task killers generally hurt performance and battery life. Android isn't Windows; it's Linux. Having little free memory isn't a bad thing.

Hence why I said "maybe " a task killer. Mine without one hits that critical 40 - 50 mb ram level where things start to lag (I have a ton of apps installed which like to run as a background service even though I only use them once or twice a week) . Also if you researched.... most task killers do NOT REPLACE stock task management....they merely lower or raise values already in place. This means closing idle processes a little faster than default ( if I don't use an application in 12 hrs....do I really need it running in the background??????) Also, you can set limits on oom values for specific tasks so they have a lower / higher priority. There are absolutely advantages to task managers......
One good example...... without it, when my memory ran in the critical 40 mb range, ebuddy services would shut off.....which is one app I WANT running 24/7. Using a task manager I can set its oom value to -17mb which virtually keeps it alive even if the system goes into swap. Also another I change values on is gmail so it can background sync and I don't worry about it closing syncing services.
Anyway, I hope that clears some things up for you if you ran as many apps as I do, and don't have a completely fresh installed os, they are absolutely helpful I know that free ram ia wasted ram ....but that only holds true until you hit the levels at which the system needs to operate properly. Don't forget....you DO need SOME ram for cache / swap!!! ( 70-100mb free keeps things perfectly smooth)
Also, an fyi for you. I know android isn't windows. I am linux guy myself and have compiled many things from source. While I may not be a GURU, im no where near a novice. I understand how the OS works. Try running ubuntu 11 on 64 -128 mb ram and tell me how free ram isn't important.

LOLZ, ubuntu?
Vanilla linux can run fine on 64mb of ram

Sure it can...but not with a current version of gnome or kde maybe using xfce or window maker. Those don't need much resource. I stated ubuntu due to its popularity lol
Was just making a point on the necessity of SOME free ram
Side note.... did you see ubuntu is functional on the streak 7 ???? Awesome!! I can't wait until it is completely ready to go. I've been experimenting trying to get any desktop session up and running but no good so far It wont be long though!!!

Bloatware and tweaking

After rooting the latest stock firmware - 10.7.A.0.222, I debloated the rom with what I found to be one of the most comprehensive list out there. I deleted almost all of the apps mentioned there:
https://docs.google.com/spreadsheets/d/1geFByRKDTOOZSIBOixO2boG1_78NUjqzkB6iozzJ4-k/htmlview?pli=1
Now, in the disabled apps list, I have the following apps that were not in that list and I wonder which one could be safely deleted without getting any errors or bootloops:
- Android System WebView
- Camera extension
- com.sonyericsson.dlna
- com.sonyericsson.dtcpctrl
- com.sonyericsson.textinput.uxp.dictionaries
- com.sonyericsson.cameracommon.permission
- ConfigUpdater
- Downloads
- DrmDialogs
- International keyboard layouts
- R2R Client
- Setup Wizard
- Top Contacts provider
- User Dictionary
- Xperia camera add-ons
- Xperia Web Runtime
I am also interested in deleting Bluetooth and NFC as I never use them. Is it safe?
I'm not an expert, but why do all the apps in odex.app and odex.priv-app keep reappearing after being deleted? Is there a way to permanently delete them?
I also found a great trick for build.prop to remove the multi-user feature when you slide down the status bar. Just add the following line: fw.max_users=1

So I'm thinking of jumping boats and going with Sammy. The Sony devices are great, but the community here on XDA, sorry to say it but it SUX!
I have the first Desire phone from HTC and the forum people there are awesome! Here, you try to share and exchange ideas and stuff, but nobody ever replies..
Why should I get another Sony?
I was thinking of upgrading to X Performance but not anymore. S7 Edge, here I come!

Heh, what did you expect from old device that in the first place was not that popular?
This reasoning of not using phone just because you didnt get replay on one of site? Im not gonna even comment that...
And this lament of "Why should I get another Sony?" are you serious here? Really? No one actually care what phone you pick, Sony is not ideal, but if you pick phone based on amount of replays on DAMN OLD phone section I hope God have mercy on your soul...
You pick phone that fit to you not to community.
But beside that, fallowing a bit weird question you ask...
Removing BT/NFC? Why the hell you would need to remove it... just DONT USE IT, if you not use it... its not working/take resources/battery.
And disabling mentioned apps? Firs of all after all those years with android I can say that removing apps is not gonna give you any advantage beside more problems. I tried that back in HTC G1 and Galaxy Spica times, but on devices with +2GB RAM is useless, even in terms of battery usage.
Second, Xperia Z problems are not lies in software but, hardware: weak battery, a bit power-hungry screen, and not that great CPU. But if you still want that placebo effect you can disable few of them:
- Android System WebView - its socket that open web based apps on android. Dont touch that even if its annoying, I found out that its give lots of random FC
- Camera extension - bcan be deleted, but it can give you FC if you use default camera often, its manage those addons like effect/panorama+widgets
- com.sonyericsson.dlna - If you dont use WIFI streaming to your TV you can disable it(but sometimes when using default music/video player FC window popup)
- com.sonyericsson.dtcpctrl - dont touch
- Downloads - its nothing more than default download manager that show download progress bar/window when you download something. Dont touch
- International keyboard layouts -its manage those useless wood/pink themes of default sony keyboard
- R2R Client -I disabled it and phone still work...
- Setup Wizard - its welcome/setup wizard that you get after first start/when configuring phone . no point of deleting it, but you can try.
- Top Contacts provider - its manage main/recent contact list in dialer app. Dont touch because its often give FC
- User Dictionary - manage your own word list that you have in setting/input, can show FC popup when entering this part of setting
- Xperia camera add-ons - the same as first one.
- Xperia Web Runtime - its build in chromium browser plugin that manage opening web pages inside system/app without proper browser.
And that odex.priv-app keep reappearing? hard to tell actually, when I had stock Rom I didnt had that problem...

First of all I want to thank you for replying. I said in the last post I have the first HTC Desire and the community there is very close and still very active. It's disappointing to see that the XZ lacks that popularity.
The list of apps mentioned are disabled. I wanted to know if I can delete them, but thanks for answering. So far I deleted everything that could be deleted and I'm left with the following apps that are disabled/freezed in the screenshot bellow.
The bluetooth and nfc service still run in the background if you don't use them so I disabled them cos I never use them. What is weird is that I've disabled the NFC app, but it still shows in the running background apps.
I deleted the international keyboard layouts and when I restarted, the US English language was gone, so I suggest just disabling it. I had to reinstall the OS.[

Since I debloated, the phone's battery and performance has improved considerably, it's not just placebo. And it is charging a lot faster too.
Thank you again for helping!

Im using Android for 7 years, Xperia Z is not my everyday phone anymore for while, but I used it for almost 2.5years. I can ensure you that initial boost is always visible after flashing new ROM/reseting. After some time and installing your apps phone work like before, I tried lots of way to speed up phones like ArcS, galaxy S3 or Motorola G(2gen) deleting system apps never give good results. google apps, apps like MovieMaker or media players, keyboards? Yes, but not system apps.
And phones that have 2GB or more RAM, and more than 8GB build in memory have no real benefits of deleting system applications. Linux/Android use RAM in different way than Windows, and even when I used heavy apps I never encounter problem with memory. And performance? Performance is more complex thing that speed of menu or useless benchmarks(beside 3D games benchmarks). And S4p chip, taking in to the account modern apps, is not well optimized and it work similar to medicore modern hardware like s4xx
Beside, what you did is not "debloading", because "Bloadware" are apps like additional Email clients, external FileManager, video/photo editors. TV applications, duplicated apps like browsers, Markets, calendars, useless games or bunch of apps that help you configure phone in 1000 and 1 ways, and of course google apps.
Sony compared to other OEMs give you really "almost" Stock system, and you just deleted/disabled applications that are valid for using other main applications like camera/contacts/network and actually have no real impact on system performance if you dont use them. Even if you see those apps in memory app list, system would dump them if it would need more memory for front apps.
Not to mention that deleting/disabling most of system apps actually can backfire to you in terms of performance/battery life, because most of apps when used, they search/detect those components like bluetooth because they use them for sharing/sending option and everytime when you use those apps, for example WhatsApp or Gallery system would try to detect if they are available.
Also system it self is build with those options so stability after deleting them can be disturbed often, even when opening setting list.
You would need to spend few days with every system changes to actually say me that performance are better, especially detailing with apps, and configuration of phone you have(signal strength, screen brightness, overall battery quality ), I made such test lots of time, and I can tell you that changes are less than 4% So I can really say that its nothing more than placebo. Especially taking in to the account that everyone use phone in different way.
You could get better effect just by modifying/adding few lines to build.prop and using apps like L-speed or Kernel Auditor, most of options doesnt work like they should, but after some configurations they can give small boost in memory management and network usage.

Severe memory leak.

I've noticed there is a memory leak after using the device for long periods of time, it's becoming a bit slow and closes a lot of apps that it shouldn't.
Also, opening the camera and using it a little, makes all apps to be reloaded.
I honestly don't feel this has 6 gb of ram, Huawei need to solve those issues, let's make them aware

I'm not sure why no on is replying to you. I have the Mate 20 X and I noticed this as well. All of my apps were refreshing the other day. My Google Podcast app even closed while I was doing something else. And I couldn't even jump back and forth between two apps without them refreshing. Then I started getting a camera error and it wouldn't go away until I rebooted. After rebooting, everything was fine. Rinse and repeat. This has happened to me several times. While it's nice to know that a reboot fixes it, it's a pretty bad memory leak. I have the International model, so I don't see an update coming any time soon.

It's not a memory leak.... The data collection buffer gets full, and a reboot resets this. China intelligence FTW.
....... JK

I've noticed that the camera and 3D live maker, kills all apps after 2 minutes of using those.
I remember the gs7e has done the same but camon, it's annoying that I'll open the camera, and everything will be reloaded.
Also besides Hauwei, Google made some improvements to the memory management in Android Pie, that could be also one of the reasons why.

I get non of this and the lack of replies proves the fact it doesn't exist. I have used mine since I received it with zero slow down.
The apps closing is because of the management of apps in the background. You can set the apps manually so they can run in the background.
This is done by "AI" so if you manage them manually you set them to run in the background and they won't get killed.

Your phone is faulty or you're trolling. The pixel 3 is crap, what you're describing here doesn't exist!

Having the same issue but I don't think it's a memory leak. Just Huawei agressive style of handling ram/apps.
Phone doesn't like anything not installed by defualt.

the memory management is horrifically aggressive. It'll be the thing that makes me get rid of it if I cant sort it out. I'm assuming this has happened with one of the updates as I've watched youtube videos of this phone being amazing on the speed tests and keeping apps in memory. Assume this was either on a pre-release ROM or an early version that reviewers are most likely to use.

My phone wont even do play-store automatic updates overnight while charging (like EVERY other phone i've ever had has been able to do).

You're the only one trolling here. Are you really such a hardcore fanboy that you're incapable of acknowledging that it could be a different software build? Chinese version vs International? I just got an update on my International model yesterday which may or may not have resolved this. It doesn't mean it wasn't a real issue. I have owned just about every major smartphone since the original iPhone, including all of the Mate phones and I also test them for a living. Some of us are actually speaking from experience, not bias.

Issue is there, but using open camera doesn't kill tasks compared to stock app, so it's hauwei aggressive memory management again.

Not noticed anything here, I sometimes have quite a heavy usage, multiple apps. No unintended closed apps. Phone is always very fast. Looking into the phone manager from time to time there's always 95% free.

I'm a one app at once guy... so no problem for me, i always close the app after i use it

The memory management on this phone is definitely rather strange. Yes, you can force specific apps to stay prioritized in the background, but it doesn't seem like there are any benefits to the hyper-aggressive method Huawei employs. What I find irritating isn't the way resident apps are juggled, but the way the app you are using acts like it is being starved of ram all the time. I need to try out a bunch of different browsers, so far the few I have been using feel like I am running a 2015 build of Chrome on a Windows machine with 256 Meg of Ram.

Try removing the stock launcher, and you will see a big difference m

So the stock launcher is the culprit? Any other bloatware that we can remove??

I have the exact same problem on my Mate 20 Pro.
Works great after reboot but after using it I sometimes can't even go to switch app mode and return to app without it reloading. Since it is coming with time used I also think it is a memory mangement problem.
I am on EMUI 9.0.0.153

Removing Huawei launcher via ADB, seems to fix some of it, but it's annoying nonetheless

I have the same issue. After using the device for some time, from Developer Options > Running Services, the System portion consumes most of the memory, leaving very little left for cached processes.

After a reboot, the System memory usages goes down to normal, until normal usage causes it to build up again until another reboot is required.
It definitely looks like some kind of memory leak.

Same issue here. I wish there was a way to schedule a restart overnight.

There is, go to smart assistance then scheduled power on/off...

Great thanks! I've now set it to restart every Monday overnight... Let's see how that goes
