Hello everyone. I have the G4, and I just refreshed it yesterday - so I have very few apps. I downloaded the kdz from a pinned thread here, even though it said it was D, it flashed B or C. But it's OK, it updated to D all on its own.
Anyways, I opened an app and it said I had 500 mb free of RAM, which is fine. But I said "Hmm, I wonder, on a fresh install, what's eating my RAM?" so I went into the Apps in the settings and it said I have more than half my RAM free (1.5gb or so). Here is a screen shot. So then I downloaded another app and it reported the same thing, only 500mb free... I'm very confused.
A. Unused Ram = useless Ram. The more is being used the better (faster) the phone will be/react while using/opening apps.
B. Don't use Ram managers
:good:

Hi, thanks for the reply. But I wasn't complaining about it being used or unused. I'm asking about why my system reports one number, while an app (ram manager or not) reports another. As I mentioned in the OP, I was curious about what I had installed that could be using so much ram that any app reports, but the system doesn't. It's a discrepancy. Not a complaint. I'd just like to understand what's happening and which number is correct. :good:

Don't forget that a lot of memory is also being used for cache. This is something the stock Settings apps doesn't display when opening it.
See for an example in the first image my current memory usage using the stock Settings app, it's stated that approximately 900MB of memory is "free". When using a system tool this would probably result in a different, much lower, number.
That is because of the cached memory. Press the three dots in the upper right and let it also show the cached memory. And presto, there it is, a more "accurate" display of all the memory being used. The value shown now should reflect the aftermarket system tools memory usage as well :good:

It means about 1 gb of apps are setup as cached on fresh install. If you clear them you will get your 1gb RAM back.
question is why do it
https://play.google.com/store/apps/....google.com/store/apps/details?id=sa.ramtruth
What does that report your free RAM as?
Thanks guys, that makes sense, and NOW I can see all the RAM hehe.
There is no reason to do it! Ram is there to be used. I just thought it strange to see on a fresh install with very few apps running to have that little free ram! Haha. Thanks guys!

I think I need help. I think Im loosing memory on my Desire. Like anyone I have installed apps then deleted them. At the moment I have about 20mb something worth of apps installed after receiving as new, but my available memory is at only 56mb.
Where is this going to? Does deleted apps leave something in the memory?
I have tried to clear all caches I found, but 56mb is worrying me. Anyone else with this prob?
Yes, I have found this to be the case. I have about 65 apps installed but I've tried and uninstalled loads more. I backed up my apps and flashed a Generic ROM. Before I started I had about 15MB of space left.
I reinstalled ALL the same apps...and suddenly had about 50MB, with the same apps. I could only conclude old apps I had uninstalled had left loads of rubbish behind.
Im seriously thinking of hard resetting, to confirm the uninstalled apps really leave all the rubbish behind.
Wonder if there is anything else on Android that uses more and more memory...? I tried look around with Astro all the folders, but didnt spot anything. Looks like the phone keeps eating memory just like Windows does...
Firstly, if you're talking about RAM, 56MB is plenty.
Second, Android probably doesn't clear stuff like you think it does. One way to see how much RAM you really have is to just do a soft reset - i.e. turn the phone off and on.
On a fresh restart I have about 200+MB RAM. After a day or a few days, Android will hold it steady at around 35MB. Never really dropping below 9% (for long).
Have you done a soft reset and seen what values you have?
It's under settings, SD card and phone memory. stays about the same after soft reset. I just uninstalled most apps... got about 70mb now. how do u get 200mb??! it is RAM I'm talking about....
do ou have facebook linked with phone contact?
check the app called "contact list" it was 30mb because of that sync for me

Maybe someone can correct me on this, but I'm pretty sure you're talking about ROM. Apps are installed into ROM and when they are run, loaded into RAM.
When I just restarted my phone now, I get 220MB RAM and I have 20MB ROM. The RAM is so high because I obviously have just turned it on and not run anything.
Oh and I have 78 apps installed (including ones that were there from the start). Don't know how many widgets I have though.
LOL you're talking about ROM and not RAM, so Cleargrey is pretty right

Up until Cleargrey brought it up no one had made the distinction...we simply referred to phone storage, which is pretty unambiguous. It's only Cleargrey who muddied the waters by bringing up how much free RAM he had...no one had mentioned it up to that point, so who is your LOL actually aimed at?
Sorry for the confusion... I blame XT9 lol. Rom is the word. I don't use Facebook believe or not. I'm on T-Mobile if that explains... think got just over 100mb free when phone was new. certainly not over 200!
If I install copilot now its 20 know... that would leave me with just 30 to install other apps. too little!
Then I think you have just run into the issue that is core to Android currently. You have a limited amount of space to install apps. I can't remember what the number is but it's something like 150MB (ROM).
Android currently only caches to the SD card. So we look to the next Android version to save us!
My issue goes actually further than that... What I ment is when I uninstall an app I have less memory left that when I installed it.
For example let say I have 80Mb free, I install an app of 5mb. Uninstalling it I have 70mb left. Thats the point... the Mbs are just fading away.

Take a look in Settings->Applications->Manage Applications
Lets you see what's hogging the space!
I have a G1 and used to see similar behaviour with K9Mail from the Market - I had a big IMAP Inbox (1000s of messages) and I think K9 stored it's database in ROM/Flash (which is even more limited on the G1).
Can't wait for the Desire - same problems...faster!

That's not really going to help when the thing taking up the space isn't on that list. That's what he's saying...he installs X app...it supposedly uses Y amount of space. He removes X app and would expect Y amount of space to become available but instead he has Y - 10.
Thanks... thats exactly what I ment. I uninstalled most stuff now.
Seems uninstalling doesnt uninstall everything - leaveing rubbish behind...
I noticed similar issues on other Android users just by Googling, but didnt find any answer to this.
To me looks like in the near future I wont have any memory left and no apps installed. Thats what Im afraid of!

Yes, may just be a bug (don't have one yet, can't comment).
However, Manage Applications shows the total size of all the Apps and some system stuff on the Flash/ROM including the Data that they've saved there.
I would look at things like 'Browser' and 'Work Email' (unless renamed now) - the Browser app on my G1 for example has nearly 9MB of 'Cache' usage at the mo'...

Yes restarted 3 times just today. Doesent seem to help...
i used a rooted htc hero before. i had the same problem but only with apps not installed from the market. i found out that there was kept a copy of the .apk files in a directory called data/drm/tmp as far as i remember. i deleted all files inside and got my space back...but i am not sure we have access to this directory without root access...

I understand that Android memory management cannot be compared with Windows memory management. CHECK
I therefore don't care that my SGN always shows about 100 MB free RAM (according to Quick System Info Pro) because you know, it's only a number. CHECK
I dont't have any lag when starting and switching (most) apps on my SGN. CHECK
I have installed only the most important apps (for me). Counting only those running as a service/widget and therefore needing some RAM permanently: Live wallpaper, Light Flow, Calendar Widget. CHECK
BUT:
Pressing "recent tasks" while BROWSING (e.g. opera mobile) and switching to another app like "google reader" causes opera mobile to close in background. And every restart takes about 2 sec and a reload of every web page tab.
So 100 MB free RAM is not just a number - it's a major problem for me. My previous device: HTC Desire on CM7.1 and I could not remember that a simple task switch closing opera in over 1 year!!!
Android 4.0.1 always seems to close the app that uses most RAM - and that's Opera. The task manager shows at least 4 other unused apps (settings, google mail - no widgets used) that use 120 MB in total that DO NOT get killed!! Even if they are unused for quite a while. Don't you think too that Android should priorize the foreground app and the last used foreground app instead of apps that have not been shown for minutes? Isn't switching between too apps the most common use case? SGN's "1 GB RAM" is pure deception to me. It's what Samsung has built into the device but not what you really get.
How do you cope?
[Sorry for my bad English but it just flowed out of my angry fingers]
I haven't had any problems with this whatsoever. Try closing tasks yourself so the system isn't forced to close one for you? Worth a shot.

Closing tasks before surfing is not what I want to do on a high-end device with 1 GB RAM. I want to use at least 2 apps concurrently and I think that this is not much to expect...
I typically have 275-300+ MB free at any given time (according to the settings page).
Not sure how your managing to use so much. I've yet to have android have to close a app for me.
Solution: Use a different browser.

That's the issue. The value of Opera is set too low where the Android system will close it first over other processes. It doesn't care that it is Opera, just what the value is. You can check all that with Auto killer memory optimizer.

Auto Killer shows that Opera will be the process most likely to get killed, that's true.
But why is it that killing is needed so often?

I don't think Android sets the values. It the app itself. So they programmed it whereas they wanted it closed more often than not. Like someone said, you can reconfigure the app the raise the value.

I did a reboot (first one since 3 days when I unboxed the device, it's so damn stable :-D ) and know I've got ~ 200 MB free too. Maybe I had a leaking process which led to this problem??

more than likely. its probably an app that really isnt made for ICS.
or it could've been an app with a high value for keeping in memory that was using quite a bit and would never close (games are usually set that way)
And Android works on thresholds, I'm sure you are aware. So once your device gets to a certain memory level, it starts to kill processes with low priority. So maybe you have too many things running in the background or Widgets. Get rid of things you really don't use because they could be using resources.
I'm using a Droid RAZR, which is bogged down wth Motorola stuff, but auto killer still reports 315 MB of ram. I've frozen much of the bloat though.

You don't set the value, Android does that based on requrements of the application, what type of application it is, and what state it is in.
What I did with my Opera Mobile mod, was to add a dummy service with high priority that don't do anything. This sets the OOM value to 2 when Opera is not visible in the foreground, this is just slightly below the priority of the keyboard.

My ram is only at 46mb-100mb if i'm lucky. it isn't a big deal with the way RAM works. you actually want your ram used rather than free.
use diskusage.

if you look at silentvistor's sig, it gives good ideas how to reduce background processes. you can also install tb and freeze a lot of the unncessary apps if you are rooted.
i have ran tw and aosp roms, and never had close to that much free ram unless i'm constantly closing out of the apps and killing them. it actually takes more battery to kill and fully reopen an app than it does to have it running in the bg. just get rid of the apps you don't want to use/run in the background.
use diskusage to find big folders, go in there, and see why you have such low memory. if it is stuff you want to keep, get a big sd card and move it all there or use a sd swap script.
Looking for a App that does as above without taking up much memory in the background whilst doing so. I trialed Smart Booster app and it allowed me too disable auto start for apps I don't need and hibernate others etc but sorta felt like the app itself drain my battery just as much as the apps that were auto starting. Thanks in advance
It's not free, $1.49. But it's worked for me in the past. Personally don't think it will be very useful on this device.

Why do you want free RAM? Free RAM is wasted RAM. Android doesn't need you to constantly clear the RAM. It's actually bad to do that because you need to use more CPU power to recompile the whole app when you open it again until we fully switch to ART which pre-compiles all apps.
Also Android by design will dynamically close apps to make room if it needs more RAM than you have available. Plus not clearing it will safe battery because the CPU will run less cycles when you use apps.
That's just my opinion, however I'm sure you have a reason as to why you wan to clear the RAM. I just thought it was with mentioning the above in case you didn't know.

The reason is very simple. The Camera use a lot of RAM and RAM is not enough on Pixel 2 XL (or 3)
Right after reboot, I usually have 1.4G of RAM. and after some use, the available RAM will stay around 900MB. Most time when camera APP starts, the available RAM will drop to 300~400M where the phone will struggle and try to kill a bunch of background service, app, etc. This creates the lag and unstable.
The only way to regain all this mess is a reboot.

Ram usage isn't a bad thing, free ram is wasted ram, and I get that the camera app uses quite a bit of memory, after all, taking a HDR pic means taking a couple of pictures, saving the raw (~40mb per pic or so) in ram and merging it in to a single picture. But 4GB should be enough for this, and the phone shouldn't stutter not should it be closing apps that were recently open, it should be cleaning stuff that's longer inactive.

I'm guessing parakleet assumed you were using the recently ported camera app by a dev that enables Night Sight for P2's. That feature hasn't yet been optimized or enabled for phones other than P3's. If you are just using the stock camera app from the Play store using HDR+ or enhanced for a single picture, then no the phone is not supposed to lag and you have a genuine issue. Is the phone getting warm at the same time? If you are taking multiple HDR's close together then maybe... Mine only lags a bit processing Photospheres, but not long. You may start with resetting the camera app settings (or all app settings). Make sure you wipe the camera app data.

I never said RAM usage is a bad thing. I just said what I observed on my phone which behavie very similiar to OP. My 2 XL struggls when the built-in camera running and since I have memory monitor app showing me real-time memory usage status, I can see the 2 XL's RAM become extreme ly (~300M) and my background app (including launcher) got killed all the time.
What you said above is what is INTENDED. But what I said is the real world result.
If you own a 2XL, just use it for couple of hours (this never happens after fresh reboot), then run camera app, taking 2 pictures, then return to launcher, then open camera app and taking some pictures. You will see this real world issue.

I believe your reply is neither helpful nor correct. Although Android is based on Linux but Android havily turned the memory management parameters and are running with millions app combinations on millions of machines (phone) with millions of different usage pattern, network status.. The behavior of each phone is bound to be different. What works on one phone is not guaranteed on the other.
Answer like yours assuming other people is lessk nowledgeable on certain topic then yourself is not a good thing on XDA, we are here helping each other here, try to find out answer together.

This is the problem. You just need to do a small amount of reading to understand why looking at free/available memory is not that useful. 5 minutes of reading is all it would take.

Still not helpful. Sigh....
If you cannot provide any useful answer to OP or my real world situation, then please do not reply to this thread further. You are wasting our time.
If you are here just to judge the knowledge of other person you don't know at all, then please leave this forum. You are just being a troll. (a polite one, I admitted though.) We don't need troll here.
I do hope moderator can close this thread since this is getting ridiculous. OP and I have problem on 2XL's camera app issue which might related to memory management issue but troll like you insist we need to read some text book while not providing any explanation nor solution.
And to answer your question, yes, I did read the Linux memory management logic and I also read/experiment a lot more than just that. "Free RAM is bad RAM" is a myth that only applicable in certain situation like data server, since their primary function is providing data and caching data stored in slower disk in RAM is a really a good strategy.
However in modern phone, people not want only data, we want to switch between unspecified APP thus it's important to also have app cached versus data cached (also the data we want is usually changing on the cloud). Beside, Android memory management (at least on my 2 XL Pie) has a arguable bad habit of killing a bunch of even persistent app while available RAM is lower than 350MB (based on my observation). Instead of process my immediate request (the camera app), the phone spend a lot of time killing all other apps which causes the problem of slow performance on my 2XL as well as an explanation on OP's problem.
If you have better explanation or solution please provide, if not, please just shut up.
