After 8 months google finally fix the memory leak in android lollipop. Thanks :crying::crying: Am I dreaming?
Having the memory load increasing is not, in itself, a memory leak.
The Nexus 5 comes with 2 Gb of RAM, the goal is not to have memory load below 300 mb in every case (or you can buy a 512 mb-RAM smartphone)
The leak is a bug in memory management which increase memory load without any limit, thus slowing the device and crashing it. I did not experience this under 5.1 with Franco and stock kernel.
I can confirm that franco kernel does not solve the issue. For me the issue is easily reproduced by opening farm heroes saga and swiping it away, After a couple of times the system ram goes up to 1.4gig

This is kind of interesting. I wonder if the system management is to blame or apps themselves.

I found a solution. If you change the kernel (for example Franco kernel) all problems are solved.

did you write about this in bug tracker ? if not plz write so they can look where need to change some thing.
and btw to be frank i'm not having any memory leak or any other buy on 5.1 and i feels everything even better than KK also battery life is as good as KK after 5.1 for me
and finally did you do factory reset After flashing factory image ? if not do it , it seems unnecessary to lot of ppl to F.reset after fresh install but it does solve many problem so do it if you didn't and remember it for every time you flash the rom :good:
Issue stared and '+1 confirmed'.
Can someone mark the bug as critical?

The same problem with franco kernel, bad luck.
To recreate the problem, simply start a game like Farm Heroes Saga, then close it by swiping away. For each time I do this the system memory increases 100mb or more until there is no more space and then cell phone stops responding. Additional I noticed than when I start Farm Heroes Saga for example the free memory on ‘Show Cache Processes’ is negative as can be seen on the print I took, and there is no free memory, this problem can be recreated even in the first minute after boot simply by starting the game.
i don t know if is due to the memory leak but after 3 days (fresh factory image flash) i m facing the annoying launcher redraw and high system memory usage:780 mb with 1,2 gb of peak

I dont want to create a seperate thread so I am asking here. Got Nexus 5 a few days ago, started reading about 5.1 update and memory leak issue. Tried to update to 5.1 but gave up(usb driver issue). Today I noticed that ram usage for apps increases and does not drop down after shutting down apps (games mainly). System ram is constantly about 300-400 but app ram got from 300 to over 600 in about 6 hours. Is this also a memory leak or maybe apps just do not completely shut down?
Memory going up does not mean there is a memory leak, it means memory no longer in use has not yet been garbage collected which is fine.
Yes, I wouldn't go purely on what the stats say in Settings > Apps > Running.
I haven't made my mind up yet - memory usage according to that screen is even higher than it was on 5.0.1 yet apps aren't killed anywhere near as often. Of course, it's early days though.
It's been said before, but sadly the new "norm" is now becoming 3GB RAM for high-end devices... and most new versions of Android are going to aimed at running best on the new handsets. I suppose that's to be expected.

Isnt suppost Linux do same memory management with 2GB or 3GB of Ram?
Wich leads me to if KK,JB and ICS didnt had this memory leak problem how come this happens in LP?
That is one thing that I dont understand....

Of course it is,just to force older phones users to buy new high end Android smartphones with more RAM. Now 3GB of RAM s getting standart,next year 3GB of RAM will get too little and 4GB of RAM will become a standart and so on..This is how marketing works.
My N5 (Factory Reset then Flashed Factory Image then Factory Reset) is up since 73 Hours, it uses acutally 490MB RAM for System and 898MB RAM for Apps,
in these 73 Hourse the App-Drawer was not redrawed once. I hope it will run like this for a long time.
The only thing that hasnt work, was the flashing with the Flash-All.bat.

exactly ! but ppl need to understand that what they need with phone.
i don't see any app that need more than 2GBs for ram on market plus multitasking is exceptional in N5 for me bcz i don't use tons of chatting apps who always runs and eats all resources of phone , i use heavy games and N5 still works great with highest graphics...and i bet none of Samsung or any other premium devices works with them as impressive as this 1.5yr old device still do ! so for me N5 is still more than enough
phone shouldn't be excessive better in specs than what you wants from phone. Bcz it does't make any sanse unless one have lots of money and he/she only want to waste it one way or another
I thought this was fixed at first. I picked up my phone this morning and went to check news and the whole thing was froze for like 5 seconds then starting working, but stuttering. Do I checked apps and low and behold I had about ten apps restarting, just like in the previous lollipop. Except this time I only see half my apps restarting (so far) instead of nearly all of them.

sounds like almost my case
I've read several android blogs they claim damaging, HTC, ect have fixed the memory leak in their roms (although I heard people claim this in cm12 also). Just out of curiosity can anyone confirm this is true?
I tried loading and swiping CoC 5 times and my free Ram still remains at 1200.
My battery life has definitely gotten significantly worse after 5.1. Drained over 20% in just an hour with very light usage.

Hello everybody,
I recently bought a galaxy note (this past saturday) and from day one, I've been having problems with the phone being too laggy. I've noticed that RAM usage never gets below 4-500 and when I open even one app (like facebook or the browser), it immediately spikes up and can get as high as 700+! Surely this is not normal! My Galaxy s2 does not have this problem at all.
Even after a factory reset the problem persists even when I haven't even installed any of my own apps yet! Could this be a hardware issue? It's running on 4.0.4. I've also had FC's. Tried switching to a costum rom (Rocket rom), but it has the exact same problem and even a slightly higher RAM usage.
I took it back to the store the other day, and the salesman pulled out their test phone (which had the exact software as mine) and it seemed to be having the same problems with the lagging and high RAM usage.
HELP!

All I can tell you is that with a CLEAN install, I'm usually sitting around 600 megs used. And then after all my apps (including the ones that are scheduled and such) I sit around the same as you, 700 or more megs used. I feel your pain with the RAM issue. It seems that it's because of all the TW drivers and software. I am really glad that they decided to up the memory in the SG Note 2 to 2GB. I really hope that things do get smoother though with JB at least. But you're not alone.

Flash gb rom in pc odin and while in gb rom go to CWMR and do the 3 wipes then flash ics rom in pc odin.
Try removing those unnecessary cluttered stock apps that you don't need (thru Titanium Backup), make sure you wipe cache partition & dalvik cache (only) in cwmr.
Reboot recovery and reboot system.. Check again if your still getting the same high Ram usage.
Uninstall google maps & facebook

AMEN!!
I just want my Note to take all my RAM.
Check the developer option under settings tab
No further posts on this I guess but here's what I have observed:
1. Go to settings
2. Go to developer options ( 2nd last option)
3. Select "Background process limit". You will have plenty of options including "No background process".
4. Stop all unwanted running apps in the "applications" -> "running" tab
5. Press the home key for few seconds, you will see some apps shortcut displayed. Swipe it left or right to clear it.
The RAM should stay within limits for a long time. After a reboot the above process might have to be repeated.

using dev options and limiting the process causes random refreshing of homescreen and apps not to work properly.
using multiwindow is also very difficult.
apps closes away some time while navigating away..
Using the App section of Dev options is not a very good idea on a daily run.
I've been suffering this alot with JB/ICS rom, my favorite thing to do after flashing a new ROM is to remove all the bloat wares, but that doesn't help with the high RAM usage (always uses up to 700MB+). So, I decided to flash back to JB a few days ago, and guess what, I open 7-8 apps at the same time with RAM usage is about 500-650MB.
As I read here and there, GPU rendering consumes more RAM, so...I think you get the idea
Source: http://developer.android.com/guide/topics/graphics/hardware-accel.html
And with JB, memory leak is even worse.
Unfortunately ram managers do nothing in increasing performance or battery life its a complete myth. Ram itself is only accessed when needed for backup or temporary storage of small files. The ram management on Android will utilise as much as it can with usual apps used and system management. It has no effect on battery or performance UNTIL you have a leak on the rom which does happen.

I've always believed that free RAM is wasted RAM! Don't care too much about RAM consumption! Android is good enough to deal with RAM without task managers (actually they're more harmful than helpful!)

I have my G9 for about 2 years now, and it's the first generation 512mb G9 1.0ghz.
All these years I updated every firmware that Archos released, so also used to the bugs and problems that sometimes occured.
Using 4.0.28 a long time now, but I think it's not repsonsive and has a lot of lag. Sometimes waiting quite a while to start an app for example.
I know that's also caused by the 1.0ghz and 512mb, but I want to try a custom rom IF that's faster.
I know all the custom firmwares are based on the official firmware, I read almost all the topic about them, but I'm not sure which firmware to choose. Hope someone can give me some clues if installing another firmware could make my G9 faster. And if so, which of the firmwares should do the trick? Somewhere I read the 4.0.7 should cause less lagging on the older generation tablets.

I'd be interested in that answer also, I'm on Surdu's custom ROM which was great at first, but now it's lagging like crazy. I can't see anything running in the background that would cause it.

Although there are a few 'custom' ROMS that have some features like overclocking... overall, the VERY SMALL increase in performance of them simply is not worth it (at least not to me).
The slow down is also not really due to having only a 1GHz CPU and/or only 512MB of RAM either. It's a combination of 2 things...
#1) The totally STUPID way Archos changed their Media Center apps (Video and Music) so that the device constantly starts 'indexing' files (even when it should not do so). Heck, it even tries to 'index' pictures, music, or video files of certain game apps when you try to install them. When your device is 'lagging' take a look down in the lower right notifications to see if there is circular arrows indicating it is 'indexing'. If it is, that will slow the device down to a snails speed until it gets done.
#2) Many of the new Google updates (Google's own app updates) are now becoming far to over bloated with foolish (and, as far as I'm concerned totally unnecessary fluff).
The best solution to #1 (on my end anyway) was to simply go back to 4.0.7, but there is some extra clean up work needed to get that all straightened out. Even then you can still end up with the #2 problems (simply because Google wants everyone to buy new devices so that they and everyone else can make more money).
Sorry, I'm just way too tired and about to fall asleep here to explain all the details about how to get back to 4.0.7 and clean things up right now. All I can say for now is that I am far more happy with 4.0.7 than ANY other firmware on my end. YMMV.

In know about the stupid indexing service. I can see it running after rebooting my tablet, but almost never when using it.
Maybe I'm going to install the official SDE from Archos (that can also be installed on 4.0.28 since a few months) and after that install a rooted 4.0.7 and then disable all the services I don't need. That might help a bit.
I suggest 4.0.28 or 4.0.7. 55mls hates firmware after 4.0.7 but .28 has been good for me. I don't store any media files so indexing doesn't affect me. Prior firmware have bugs with some games for example too.
Also on my 80 G9, I think 4.0.7 has some wifi strangeness. Disconnects occasionally.
Alternatively you can roll back to 3.2.80. This one works quite well overall functionally. However it's certainly not the fastest. The GUI seems slower to me than with the 4.x OS. Honeycomb also has some caveats like occasional lack of app support and the fact that it's sort of a Android 4 prototype in general. On the other other hand, Honeycomb is an interesting bit of history and I like its UI theme.
having the same tablet here (also with ""only"" 512mb ram).
i'm running 4.0.7. now, which works a lot better than 4.0.28 for me, but still has some lags from time to time..
I guess I should have also mentioned a 3rd reason in my previous post that some people may not be aware of...
When installing apps, some do require extra 'temporary file' and/or 'cache file' storage space. By default, Android normally will pop up a "memory low" notification when the amount of memory drops below 500MB. Of course, that means the systems has already gotten so low on memory that it can no longer operate correctly.
On my end (and my devices) I've found that things start to slow down already even when the 'free space' gets down to 1GB. In general, if you can keep the 'free space' up to at least 1GB (preferably 1.5 or more) then there is very little of any slow down.
Of course, now days, almost all the newer devices come with at least 16GB of flash memory and 2GB of RAM (not to mention quad core processors) simply to be able to handle all of the extra fluff Google keeps adding into things with their own upgrades.
Since Google is making the exact same mistakes Microsoft did years ago (taking a good OS and cluttering it up with so much extra fluff that nobody wanted/needed)... well, I've pretty much lost all interest in Android now. I bought my Archos G9 tablets for only one reason and that is to do what Archos claimed they did at the time. I did not expect, nor did I ever want them to end up having to go thru multiple upgrades (from either Archos or Google) to do anything more or less than that. Unfortunately, every upgrade now seems to actually lower (or even restrict) being able to use my Archos devices BELOW what I originally could use them for.

This seems to be something all devices have a problem with. It's probably a flash RAM issue. When the flash gets near full, it needs to do more erases+writes to store new data and this just kills write performance.

My son installed a lot of games on my Archos in the past and there was not a lot of free memory left. This week he bought a Asus MemoPad HD7, so I uninstalled all the games on my Archos.
And it seems my Archos is a lot more responsive now and has less lags. :good:
Still on the official 4.0.28, but this is good enough for now.

Another thing you can do, especially if you have a 512MB device, is to keep watch for apps that run extra background processes. For example, do a reboot and load the system monitor app and see what is loading automatically on boot up. The 512MB devices really don't have enough RAM to go around beyond the basics.
Hello,
I've updated my Nexus 7 first-gen recently to Android 5.0 and since than have spent a good amount of time using it. I use the tablet for work and fun through out my whole day, so snappiness is a big factor for me. With the 4.4 update, the tablet just got a lot slower, sometimes I needed to wait for a few seconds before I am able to kill a task. Clearing cache didn't fix the issue.
Made me think about that 5.0 update a lot. (Note that I actively started using the tablet only a few months ago. I had it for 2 years but broke the screen 3 weeks after buying it and only now I decided to repair it.)
The 5.0 update it self took a good 45 minutes. When I loaded it up for the first time, man it was buggy, I couldn't complete a single task without it bugging out. All of the Apps and settings were there untouched. The first thing I did, was go into recovery mode and cleared the cache. Then I cleared the cache for every individual app. And that boosted the performance by 100%. Next, the animations, I cut them down to 0.5x and turned on GPU rendering (just for testing) turns out that helped out a lot. I didn't notice a difference in load times, like some articles suggested.
However there are a few quirks, the sound lags behind the slider, so if I crank up the volume to MAX it will take a moment to do so. I often found my self having to tap the apps drawer button more than once to open it. And the killing of tasks is not as easy as before, now you have to slide from one side to the other in order to kill a task you can't just kick it to the side. Also, the auto-brightness is really aggressive so I disabled that. The WiFi status, when you click on a WiFi connection seems to be broken since in portrait mode all the letters are separated, and at first I couldn't make out any of it. And the biggest downer for me is the keyboard, I think they didn't do any favors with it. I have larger thumbs and it will take some time getting used to the keyboard. These are all small things, but they affect my experience.
Now the good stuff, where do I begin? The interface, it's great I like the design and the contrasts. Performance, I guess that's the biggest question since this is not exactly cutting edge hardware. To summarize it, it's good. I haven't had any issues since I cleared the cache, apps are running as they should, games as well, multitasking is as expected, fluid. Later on I switched the animations to 1.5x and 2.5x. no issues there. Boot up times, something completely irrelevant to me, but since there are people that would like to know, it takes around 30-40 seconds to boot up. However, Chrome is still the biggest enemy. If you want something to make your tablet miserable and make you wait and get frustrated because of it's unresponsiveness, you won't need to search far, just get Chrome.
All in all, the update was a step up, and an improvement.
These were my 2 cents on the subject. Hope it was of use to someone.
thanks for the review. I also updated a few days ago when the ota came through. So far, I'm experiencing terrible lag. I don't have anything stored on the N7 and don't have many apps. There is a ton of available storage on my 32gb. I did a factory rest about 3 months ago, as I like to every now and then to give the N7 a fresh start. I think I may have to yet again and keep my fingers crossed. Unfortunately, it's unusable at this point.
My experience has been variable, but not unexpected. In the past I have had issues with installing OTAs resulting in poor performance -- sluggish response to touch, certain apps immediately displayed odd lag, etc. Going from 4.4.4 to 5.0 was no different. So, I performed a factory reset and the effects were stark. The performance is exactly where you would expect it to be for Lollipop i.e. it is smooth.
HOWEVER, all is not well. There seems to be a set of problems that I suspect is related to Lollipop utilizing the ART runtime. Certain apps, even before performing a factory reset, were really really slow when running the first time. I have experienced this before: when I tried out ART when it became available on the Galaxy Nexus. Two common apps this occurs with are Facebook and Mint. Who's to blame? The app developers? Google? Don't know but hopefully these issues get resolved soon.

Ugh, that is quite an issue. Have you tried wiping the cache? You should check your usage, you might be able to find out what's hogging your system, unless it's the OS it self.

I also tried out the ART on some devices, mine were not even supported. There were a lot crashes but I also noticed some performance improvements.
Does factory reset also wipe the cache?
My Lollipop experience with my 16 GB WiFi-only Grouper isn't as good as yours. First, I thought I messed something up by rooting it with NRT, but after a manual factory image (flash-all.bat failed out of the box) without root it didn't get any better.
Most time its not as responsive as my N5, I've already had 1-2 minute hangs followed by hung apps (Google Search/GNL, system in most cases) and heavy lagging under most conditions. From time to time its getting close to 75-80% of the smoothness experienced on the N5 (which has better hardware, of course).
I have no idea what went wrong, I've already enabled 2D GPU hardware acceleration, but I'll definitely wipe the cache in recovery once more - you never know...
Thanks for the extensive review - Chrome is just a pain in the a** if you don't have at least 2 GB memory available.

I suggest wiping cache, because you get to keep your apps and settings.

One thing I forgot to mention is that after the cache wipe the tablet was fairly fast but I also went into Settings > Storage, and noticed I have a lot of app data which frankly shouldn't be that much. I then went and cleared cache manually on every app and as it turns out, I managed to scrape off another 1GB there. So, I'm not sure how that would affect the overhaul system performance but it sure helped me get the snappiness I have right now.
Looks like wiping the cache had an impact on performance. I wasn't able to play around much, but it definitely felt faster after first reboot.
Too bad I just noticed my user partion only had 6,x GB (8 GB image obviously) - there are so many ways you could f**k up an Android system - so I'll have to format user data once more, approximately the third or fourth time in the last week.
Sometimes I understand why people fancy those awful Apple devices, but let's hope the speed boost persists.
Go in and delete all the apps in system folder that can be installed from play store and are not needed. After installing the lollipop images you have 11mb in system which seems to be main cause of lag. I freed up like 160 mb and no lag or stuttering. Not sure why google kept things like dialer and other things unusable on the tablet in there.
Also get now launcher and delete launcher.
For even better performance get faux kernel (Set kernel up to his recommendations) and/or install aosp 5.0 F2FS with minimal 5.0 gapps.
Oh I do have a problem with WiFi being weaker on 5.0 though.

i am getting terrible lag too. last week i updated with the OTA file. wiping the cache improved performance but only for a short time. i guess eventually if ii want the speed back on my 2012 nexus 7 i am going to have to root and go back to jellybean

Thanks, that sped up things significantly. It's definitely a memory problem, because event on full stock setup you're getting glances of Lollipop smoothness.
But WTH is Google delivering a potentially lagging factory image? Couldn't they just resize /system by default in order to fit in all apps nicely? Well, that's Android - if it doesn't work, you have tons of options to fix it.
After my old N7 screen broke, I got a new refurbished 16GB unit for about US$100.
Had some bootloader issue earlier while trying to flash lollipop, and had to revert back to 4.2.2. Then it got all the OTA up to lollipop, and is running really well since.
Loving it now, better than most non-lollipop newer tablets around...
Lollipop is big disappointment. I hate new notification (double swipe down to access settings)
I am back on 4.4.4 Slimkat rom with Legokernel and f2fs
now is system smooth without lags
Listening to some of the advice in this thread, I rebooted into Recovery and wiped cache (I did it 3 times, because why not, right?)
In addition, I went into the developer settings and turned OFF "Force GPU".
After doing both of those, my performance seems to have greatly improved (specifically Chrome, which was borderline unusable).
For reference, I flashed the factory image from 4.4.4, and didn't get it OTA.

Not any more! I have three new iOS devices and things are far, far worse since iOS 8 dropped. Apple now holds the lag crown. At least with Android you can revert back to earlier versions that worked. With Apple all you can do is whimper at the master's feet.

UTTER nonsense. Stop it. System being full affects nothing; it's read-only.
Is there a way to disable the storage encryption that is enabled by default? Disabling this apparently had huge performance upgrade for the nexus 6

understand what you are saying but after doing so i have no lag.
Have 2 x 2012 and both were lagging. After trying other things i deleted stuff in system and both are very smooth now. Very happy with them.
Even wiped and re installed one and just deleted stuff in system, to make sure it wasn't something else or a combo of things i did prior.
Can anyone link me to a custom rom that gets rid of the memory leak present in Note 4 on 5.0.1. It's crazy that Samsung would even release 5.0.1 they should have skipped straight to 5.1. My ram usage will not go below 2.1GB. I have tried Clean Master, Battery Doctor, Rebooting and Force Kill.
It has to be a custom rom with Touchwiz not Cyanogenmod because I love the Note 4 features
there isnt any memory leak on any samsung lollipop only s6 has it.
I've never seen my Note 4 even get to 2GB in use, ever. What are you running to get it so high?

My only question is: Have you seen any drawbacks in usage or it is just the effect that you are looking at the available ram and you see it over 2GB and assume it is wrong? Because let me say this: Note 4 and 5.0.1 does not have memory leak. Did you experience apps crashing on a regular basis?The "memory leak" basically stops RAM from clearing out automatically and disallowing other underlying processes to make use of the space. This in turn results in the apps getting killed or crashing automatically. I assume not...apps crashing constantly is the first sign of a memory leak. The only memory leaks reported were on Nexus devices and Google patched them. So basically...free ram is wasted ram on an Android platform. And if this high usage that you see (over 2gb) does not cause apps crashing and phone slower you have nothing to worry about it's just your OS working as it should Cheers!

Where are you seeing that figure? If it's in the touchwiz memory manager than that's a misleading figure since it count cached applications in it's figure which isn't really used memory. You need to check the real Android memory stats to see the real usage.
Im using task manger. this is with all apps killed.
K, thank you for the quick replies. It says a lot in Clean Master 85% of available memory is being used and wanting me to keep having to boost the phone. Have you guys notice any poor battery life with Bluetooth on running lollipop? Can't seem to get half a day usage even with the screen off. It also says in Task Manager 2GB+ is being used. I keep clearing it, but it does not go down. Could it be because gear manager won't close, as it will disconnect my Gear S
No problem here
I hope

You have only one problem to resolve. Deinstall Clean Master, don't believe in phone "boost" and some unpossible clean effect.
If you haven't problems with applications crash or freeze your "problem" doesn't exist.
Bluetooth has significant influence on battery life. Not services, but bluetooth radio itself.

Stop killing apps with ram booster. It will make your phone slower in reopening apps and consume more battery. Search for some articles on Google to find out why the ram cleaners or launchers with ram cleanear included are so bad for your phone. Android has a very good ram management and you don't need other programs. If you want to see less consumption on your ram disable or uninstall the apps you don't use. Try to open and close a simple task like phone book and after try the same thing after you killed the process with a ram cleaner. You will see that it takes a long time to re-open, and also your procesor will work harder to open the app.

I'm still going over some logcats but I'm positive the way 5.0 handles RAM is a problem. Haven't been able to pinpoint the issue yet but 5.0 is definitely allocating memory differently than 4.4 and not necessarily in the best way.
Why am I doing any of this? Because fun of course, but also because I noticed home screen redraws were becoming more frequent, and apps were refreshing when a device that has 3gb of RAM shouldn't experience too often. When compared to my Note 3 on 4.4, side by side, running some taxing apps, I've seen a substantial difference.
K thank you. Will uninstall Clean Master and see if my performance improves. Report back. Anyone found a way to open camera when rooted without unlocking phone with fingerprint by double tapping home button. Sorry about posting it in this fourms, just wondering. Hope the Zerolemon battery case improves my battery life, getting it soon. Heard it's not very accurate being that it has 3 batteries and the phone doesn't always get the right reading
I have the same thing here even i noticed apps need to refresh when multitasking frequently

i think there are a few leaks in 5.0.1, so far we have 1 leak fixed in the kernel and 1 in the rom (thanks to robocik) but ram usage remains high.
not that that is a bad thing...apps only open faster, so that's good, but especially the touchwiz redraws are insane after a while.
every time you press the home button or the greenify button, it redraws the launcher completely.
so even after 2 fixes it's still present

im using totaly stock and my ram usage is 1.83 gb constantly with tw launcher and nova makes it 1.6 or something. never saw a single launcher redraw on note 4 and ram usage was totaly same for me on kitkat too. im having serious ram issues on s6 but didnt see any problem with note 4 lollipop

odd, if i don't use greenify and just stock touchwiz i have an average of 2.3Gb of ram in use
and it redraws the launcher on every press on the home button
thankfully the n4 doesn't have it as bad as the s6, but it could be a lot better
Never had a launcher redraw using Nova and Servicely to kill apps on screen off. I'm running at around 2.2GB of ram usage always.

dunno generally i dont even close any app and i dont have any problem with ram or multitasking.
Seems like the majority of users in this fourms use Nova Launcher. Does it decrease the ram usage. At the moment I am running Flow Home, I think it redraws everytime the home button is pressed.
I know that there was a memory leak issue with 5.02 but it's apparently fixed before the fw was deployed:
http://forum.xda-developers.com/crossdevice-dev/sony/clarification-xperia-lollipop-fix-t3087240
So that doesn't help explain my issue. Very often, when I have any combination of Spotify + Google Maps, Spotify + Chrome, Chrome + Google Maps, etc open, the app that's in the background will just flat out close. It's stupidly annoying while driving when my music just dies, or when my navigation disappears and I miss my turns because I don't hear any audible alerts. The issue goes away after a fresh restart, and will come back usually within a day or two.
I did not have this issue on 4.4.4.
My free ram hovers around 500-600MB at all times.
RAM status today
RAM Status after fresh restart
I absolutely hate why nothing can be properly backgrounded like in iOS. The moment I press the home button or switch apps, all my open tabs in Chrome have to be reloaded. Filling out forms in a Chrome tab while referencing another app is almost impossible... This was actually an issue on 4.4.4 as well as 5.02. I have not found any way to fix this, no matter how many times I restart my phone. I don't think my old Galaxy S3 had this problem...
Why does Android make us work so hard for a properly working phone, if we can even have that at all? As a consumer I should not have to go through 7 levels of technical hell to make a phone work properly. This isn't Linux.
Sorry for the rant. Anyone know what I can do to fix this? Everyone says RAM clearing apps are bad. So that's not an option right?
.726 has this problem and as far as I can recall it was pretty serious. Fortunately in .26 the problem has been solved. It's about memory management in lollipop being poor rather than memory leak.
.26 hasn't been released for D5803 USA right? I don't see it in the firmware thread
Still doesn't explain the Chrome issue. Whenever anything is backgrounded (not closed) in Chrome, all my tabs have to be reloaded. Most of the time now, even just switching from one tab to the next within Chrome while it's open forces a refresh of the tab. WTF
I never had any memory leak issues with any of the firmwares. Try to turn off Stamina mode just to see if it is affecting (I have it off, and queue background data off as well). Make sure also you have not enabled Developer Options and checked the setting 'Don't keep activities' or some other setting that limit the amount of process you can have in the background.
Dev options are not enabled. And stamina only kicks in at 50% battery. I could turn off que data but does that have anything to do with RAM?
I just called Xperia tech support and they suggested I do this:
http://talk.sonymobile.com/t5/Xperi...uctions-using-Pc-Companion-Win-or/td-p/249946
Has anyone done this and fixed the issue?
I am apparently not the only one who has had this problem:
https://www.reddit.com/r/SonyXperia/comments/356f80/z3c_502_stock_memory_leak_or_something_else/
There's an Xposed module called App Settings that lets you force the OS to keep stuff resident in memory. Because it's an Xposed module, I have no idea if it's compatible with LP or not. Also, there's a point where you can run out of memory and experience involuntary restarts if you keep too many apps resident. Still, it's worth trying, imo.
I was told that the memory leak wouldn't be fixed until 5.1 or even 5.1.1
726 did indeed have this problem. i used the xposed module for the memoryleak fix and it did indeed work...phone was much faster.
People are saying sony phones do not have the leak but the leak affects each phone in slightly different ways.
I the new .28 USA firmware running on my phone now and it is working rather well. granted i still have the lollipop memory fix module activated but i will do some testing with it off as well.
Nope, the problem is not solved in any lollipop firmware, atleast for me. I tried all the latest, reflash and wiped all (Included Internal Data) and the problem still here. Is Ridiculous how with 2GB RAM I can´t have atleast 4 apps opened without the preocupation of they get killed for itself. I remember with my Nexus 7 Tablet in Android 4.3 had a looot of apps opened and no one get killed itself, it was a great multitask experience that I can't get yet in Xperia Z3 Compact. I tried edit minfree values, uninstall apps, change firmwares, edit services.jar, install tweaks, edit my build.prop, etc. Also I noticed with the Task Manager of System Tuner app that "/system/bin/mediaserver" is always eating more than 60mb of Ram, this is since kitkat and continues to happen in Lollipop, after of some hours, this same process can take up to 160 - 200 mb of RAM!!! The worst thing is that in other devices this process don't seems to take a lot of Ram as in Z3 Compact did. Idk, it would be good that we can improve multitask in this device.
I compared the /system/bin/mediaserver usage with a Samsung Galaxy S4 Mini and it only takes 5 mb of RAM while in Xperia Z3 Compact it always start eating 50 mb of RAM and it increases up to 160 - 200 mb in some hours. You can see my proofs here:
http://forum.xda-developers.com/showpost.php?p=60569610&postcount=9
So Idk what to do now, I hear that the only good devices that take importance in multitasking are HTC M9 (M8 and M7 too) and the Asus Zenphone because they merged their own patches to ART to improve a lot how multitasking is managed in android. I think sony do their devices to kill apps very agressive, so in this way they can presume that his device is more smooth than others but useless for multitasking. Weird...

Any feedback on how .28 is running compared to .726 with the xposed fix?
Like many, I uninstalled the fix after I read the thread pointing out that having it active was pointless as Sony had already fixed the memory leak themselves, but after reading your reply, I decided to reinstall and sure enough, my phone does seem snappier. Having read the changelog for .28, it didn't seem worth upgrading unless performance was noticeably better.
I will tell you im enjoying .28 with the fix running. There are enough fixes in there to make it worth it i think

No issues on 23.1.A.0.726 here, I have averagely 250 MB more free RAM on Lollipop than on Kitkat, with all the same apps installed. :good:
Guys, the problem is not how many ram do you have, the problem is if you can multitask some apps without someone get killed. I can multitask within 2 or 3 apps sometimes, but I can't get more than that without someone gets killed...
It was to be expected that Lollipop in Sony devices would be problematic. For the time being, I prefer to stay in KitKat and then make the jump to 5.0.2.
