What is the max memory limit per app? - Galaxy Note 3 Q&A, Help & Troubleshooting

Hello.
I just learned that android has memory limit that a single app can consume, but it vary on different devices.
Does anyone know what is the max memory limit allowed an app to consume on Note 3?
I've seen an app crashing after reaching 130-140mb Is this the ceiling?
Thank you.

As far as I know system apps have no limit. User apps used to be 16-48MB and app can request increase to 128 MB if rooted. Now I don't know exact number for Note 3 (call "getMemoryClass" to find out), but I would imagine unless coded specifically for Note3, it would be wise to stay within those general limits for compatibility.

[Q] Not quite 3GB of RAM?

According to the information displayed in the RAM tab of my phone's Task Manager, my GN3 has 2.38GB of RAM installed. Naturally I was expecting to see 3GB since that's what the specs advertise.
Is anyone else seeing the same thing on their GN3? I'm wondering if this is normal or not.
That is natural since some ram will be used to run the Android system and whatever else is currently running in your phone. One thing that holds true across all ram whether it is hard drives or what not is they always advertise a rounded up number. Just an fyi.

GPU is assigned a certain block of this. This is standard across all devices. You have 3 GB ram, doesn't mean apps have access to all of it.

[Q] Make Android use more RAM

So, a lot of people want their device to have as much free RAM as possible, I am wondering if the opposite is possible.
There used to be a Cydia iPhone app called Backgrounder a while ago. It allowed you to change the way your device handled multitasking. I always set it to keep the current state of the app as if it were in the foreground. It used up more RAM but multitasking was so much better, apps didn't just close themselves, keeping only a bit of themselves in RAM for faster startup, they actually stayed in RAM fully. My Nexus 4 always has at least 600-800 MB free RAM (including cached processes) so why not put it to good use?
Is this possible on Android?
Android has always functioned like that since the beginning. It has always had true multitasking, with apps running open in the background/cached, and only get killed if there is insufficient memory available. Backgrounder was a Cydia tweak created so that iOS devices could get similar functionality in terms of how multitasking works on Android.
You can try playing around with the minfree settings, here's a guide on how to do so.

RAM usage

Hi guys,
I am curious about your experience with RAM usage on your S6E+
If I'm not doing anything (just checking RAM usage with my SmartManager) it says: 60%
- 2.2GB System & Apps are using
To me it seems alot, since it leaves me "only" with 1,4GB of RAM left.
So I would like to see your experience and I could judge better.
best,
Dpool
I just dont understand why people complain about "Ram" usage on an Android, free Ram doesn't mean "fast" mobile.

No, Free RAM does not mean that. But it means that I only have little Free RAM left, without doing anything. I'm worried about multitasking, since it supports split screen:
- 1 half of screen I'd play a game
- 1 half of screen I'd watch a YouTube video / Stream about the game
Well not all Android games support split screen, but just an example of where I can see heavy RAM needs.
Also, I did not complain, I am just wondering if it is normal to have 60% of RAM occupied by System itself. So, DemonSoul, may you share yours to compare?
Best,
Dpool

Mate,
Samsung system apps and other Google services are using a good amount of RAM. You could use App disable pro and disable some of the unwanted system apps to free up some more RAM. Samsung does have a feature to kill a process in every 10 mintues. So that app you don't want running in background you can use that feature.
Killing apps will decrease your battery life and hurt performance because Android will just load them back up. It costs cycles to constantly load & kill apps. Apps don't burden the processor when resident in memory, hence don't expend battery or reduce performance.
Keeping memory free on a Windows PC was important decades ago when we had <1GB, and when memory got full, programs were shuffled off to the swap file on the hard disk. None of this applies to Android. No phone with >2GB of RAM has memory problems under normal circumstances.

Verizon S7 edge is lacking in speed and software.

After using this Verizon S7 edge for over a week I concluded the following.
1. Cpu speed is limited to 1.6GHz - Maybe to keep heat issues down.
2. Apps. can not be moved to SD. Yes, it says it did but it's only moves cache.
3. Verizon has left off some of the software others have.
4. Ram is limited to 3.5G to start and after OS and Samsung and Verizon stuff, user has
maybe 1.6G to 1.8G to use.
5. Phone does stop and stutters at times.
6. Screen slow to respond on the edges at times.
Given all that, I do like this phone but I believe that work is need by Samsung and Verizon.
Some apps but not all can be moved to SD card. I have moved apps.
Download Samsung pay from app store. It works.
No stutters on my end so that is always phone specific: very fluid and fast for me. My iPhone 6s plus also stopped and lagged so that myth of fluidity was just that.
Edge works well for me but again maybe phone specific.
Yes, VZW did remove some things which is typical and this is not surprising or new.
Not bashing or defending Samsung, but I am impressed with this phone even owning a Nexus 6p. There, I said it. Let the bashing begin.

Well I do agree that Verizon went overboard with its meddling on this device. My biggest complaints so far are
* the assinine removal of the Samsung internet browser app which offered, among other things, an optimized experience on the device's specific chipset, website authentication using fingerprint, and the optional ability to use an ad-blocking add-on
* a completely unnecessary Verizon tramp stamp on the back of this beautiful device
I am not seeing your claimed clock throttle on the CPU, however. If I keep a floating CPU usage monitor (I used the paid version of System Monitor from the Play store) on while running, for example, the Geekbench benchmark, I have seen both high speed cores ramp up to 2.2ghz, which is very close to the rated max of 2.3ghz, and that was after me using my phone almost continuously for the last several hours before running Geekbench, so a thermal throttle of 100mhz seems not all that unlikely.
Some of your other points are true for all carrier variants of the device, and possibly all devices running Android or Android Marshmallow (for example, moving apps to SD storage has never been all or nothing on Android - it is dependent on how each app is designed by its programmers as to what actually gets stored on the SD - the app may be hard coded to use primary storage for things like cache and even documents, and the reported memory on all my previous Android devices has always been less than what the manufacturer specifies as the hardware spec - I've read different explanations for this and I don't really understand why it's true, but the S7 is far from alone in this).

Well I was using System Monitor so I tried Geekbench 3 and they both report 1.6 GHz.
Geekbench also reports 2222 Single Core and 5227 Multi Core. Also I stand by my statement that Apps do not move to SD. I have moved more than 20 apps. and the SD shows them listed under Android/Data on the SD card but after moving over a gig of apps, the dir shows less than 20 megs of data. They are mostly empty program name folders. And yes I know how to move them. So either my phone is diff from yours or...... Thank you for your input.

I want to know if anyone else is seeing these problems. As for the apps. they don't really move. Just a name dir. is created on the SD.
Ans to apps not moving to SD
Well folks I found the ans. on a diff. thread:
Samsung disabled the adaptive storage option. Here is the response I got from Samsung on the app data issue. I looks like they know the data isn't moving.
"I have checked our resources and found that whenever an app is moved to the SD card, only the app and the dependencies of the application for the Operating System to identify the app on the SD card are only moved. Data associated with the app is not moved to the SD card.
Let’s hope that our future updates should allow the user to move the apps data to the SD card along with the app.
I would have surely helped you if there was any other option to move the apps data to the SD card.
I appreciate your time in writing to us. "
So Samsung maybe aware and I hope they do fix this.

I love that browser so much I'm willing to pay someone to mod the app so that we Verizon users can sideload it onto our phones.

Geekbench reports, in its initial pre-test display, the max clock rate of cores 1 & 2, which are the cpu's 2 low power cores, and that is the correct clock rate as designed and specified by the manufacturer.
However when the benchmark is actually run, the system correctly detects the need for high power processing and the high power cores kick in, and can ramp all the way up to their maximum clock rating, assuming they do not thermally limit.
The scores you are reporting would not be obtained were all the cores being limited to 1.6ghz. You would probably be seeing well below 2000 in the single core benchmark if the high power cores were being limited to a maximum clock speed of 1.6ghz.
The score you are reporting definitely doesn't support an assertion that Verizon has set a more conservative limit to the max CPU clocks on this device, and, as I've said, if you use System Monitor's floating CPU window feature to watch the cpu clock speeds in real time as the test actually runs, you will see clock rates at or near the max speed of 2.3ghz on the two high power cores (nos. 3 & 4).
Your reply post seemed to indicate I thought you didn't know how to move apps correctly, and that I did. Not true. I haven't tried moving any apps on this phone actually, and expect I would see similar results to yours if I did so.
But as far as moving apps to SD goes, I also stand by my previous statements. Your app-moving issues have nothing to do specifically with the S7 models in any variant by any carrier including Verizon, nor for that matter, Samsung itself, but instead are due to a multitude of complicating factors, some because of Android itself, and some by the makers of the specific apps.
If you do a bit of searching on Google for discussions about having problems moving an app to SD storage, you will quickly see that it is a long-standing problem reported for many apps by many people on many different versions of Android running on many different brands and types of devices, and there are about as many reasons for it not working as there are instances of it not working right.
It's just that it seems to me like blaming app-moving problems on Verizon for mucking it up on the S7 is like blaming your vehicle's poor gas mileage on the owner of the dealership you bought your new car from. Verizon did plenty to be irritated about on this device, as well as others, but this particular issue isn't their fault. Android's app-moving feature has had problems since long before the S7 model was ever designed or built.

Sorry friend, I was not trying to blame anyone, just pointing out problems I found to see if it was my phone or if others noted the same. Apps don't move to me is a problem with a phone limited to 32Gigs. On my Note 3 I could move apps. to the SD but that may have been because I rooted it and mod it.
Now as for speed I agree I was wrong because the apps I used to check was not reading the correct speed.
Today I got an update to the AIDA64 app and it now notes the correct upper cpu speeds.
As I said before I do like this phone but then nothing is perfect and I want to make the best use of it.
Again just trying to get a handle on a new phone and seeing what others may have tried or worked out.

Sorry if I came off as confrontational - wasn't intended.
And we are certainly in agreement that there are some issues with this otherwise very fine phone. Like you, I hope to see at least some of these issues fixed or get decent work arounds for them.
App moving is a can of worms and without root privileges there is only so much Google can do with Android to fix it (adoptable storage probably being the most thorough approach, although I would argue that it's just substituting one can of worms for another [emoji1]).
There are a *lot* of apps that refuse to be moved without elevated permissions to do it. Other apps may allow you to move the executable image and related runtime files, but stubbornly don't allow you to pick where they store data and/or other types of resources, so the paltry savings on moving the runtime stuff doesn't help all that much.
And on a related note, I would certainly add to your observation about 32gigs that it was a mistake for Samsung not to offer carrier-branded phones in a larger memory size. I'm sure most if not all of the s7 owners who participate on XDA would have really appreciated at least a 64gig option.

expanding RAM usage on 12GB model.

Developer options allow one to limit the number of background apps that use RAM. But they allow 0-4 apps or the "standard" option.
For those of us who have the 12GB RAM version, is there a way to keep more apps in memory?
I keep having 5.6 GB RAM available and I want to use it...

This is a good question. I notice the same thing on my 12gb model
i was tempted by the 12gb, but having to wait two days for it to ship kept me in the 512gb model personally, never been a patient one, never will be, 8gb is already overkill for a phone anyway, heck 12gb is 4gb short of what an actual gaming PC (the kind that play actual games not bloatware) should be minimum specced to, you're not gonna need that much power on a phone and if you do you're using it for the wrong things.
i wouldn't have minded a 1tb 8gb model though, i had to severely cut down my music library for the moto z force when i originally got that.
Well I just saw 4.4 GB RAM left only. I do wonder if there is a hard limiter after which preloaded apps are killed.
Regarding the debate of an overkill, I'm old enough to remember a time when the Intel 586 CPUs were promised to have "infinite calculating capacity"
The only reason I bought this model is that the s7 model I had lasted enough (2.5 years) to become too slow.
I'm hoping this device will last longer.
In any case does anyone know what the "standard limit" of allowed process is on this model and how I can force all RAM to be made available?
stop asking shovelware developers to script-kiddie in 64 bit, there's no kind way to say it.

That option is to limit apps, not allow more.
Phone uses LMK values probably coded in kernel and its not related to option you are seeing in dev options.
Also, 6gb ram used is alot, what more do you want to keep in memory, are your apps reloading or what?
I like my browser to have many pages preloaded (640 MB) , several texting apps, email, forums, videochatting, etc. XDA app takes 248 MB. Right now apps and system are using 7.2 GB of RAM...
This really is a mobile computer for personal use and that's why I bought it. I like to have all apps and pages preloaded and use them as a reminder of what I need to stay in touch with.
Right now everything loads fine, but in the future apps will become heavier and I'm hoping that Samsung isn't limiting that.

U can't know and also you can't control it anyways, we can just hope Samsung didn't set memory killer too aggressive.
Also you should turn off auto memory optimisation in device care menu as it kills apps daily.
I did the above and can report that I'm at 3.3 GB of free ram. I haven't restarted in 4 days or killed any apps.
So it's not an issue, Samsung does allow the system to use the available RAM.

You're not supposed to be touching that option and no, your device isn't killing your apps after 4 of them are running, you can keep as many as you want in background until you run out of memory.
