Nexus 4 uses only 512MB??? - Nexus 4 Q&A, Help & Troubleshooting

Hello
I'm, still shocked.
Today I've upgraded to kitkat from 4.3. Everything stock and OTA.
I've noticed that heavy apps are often killed from RAM, so that when I open them again it takes a startup time as if it were the first time.
Then I have noticed that regardless of the apps I open, my memory usage is always around 500-550MB leaving 1300MB free!!
WTF.
Chrome is the most painful example.
1) Open some tabs in Chrome.
2) Then open some heavy apps, like play music, hangouts, youtube and calendar (maybe you should open some more to fill as RAM as possible).
3) Then open again Chrome
4) Chrome will reload tabs since it has been re-started again
If you have a look to the memory usage you will see aroun 500MBs. What about our 2GB!!!!
Being chrome so heavy, memory management decides to kill it each time, delivering a terrible user experience...
Any idea? Any solution apart from restoring 4.3???
Thanks a lot.

No kidding I'm still surprised. In the beginning I was using 800mb but now it sits at 475~mb ram usage. This is ridiculous and I'm using the heck out of it. On the downside its kicking my hangouts out of memory. When I launch hangouts, it takes a while to start up.

It looks like the system is trying to limit itself to use only 500mb. Maybe that's what Google meant with Kitkat being more optimized? so much for 2gb ram...

Now you mention it I am noticing a lot of apps restarting now. And hangouts is a prime example.

So does this mean there is now no benefit in having 2GB ram? Kind of like having a laptop with 8GB ram running a 32 bit operating system that can only see 2.

Per Google, KitKat is designed to run in older phone too, even at 512MB RAM can still run KitKat. For example, Nexus One which has only 512MB RAM and still able to run KitKat, not stock ROM per se.

are you sure??? I tried it on purpose. I opened asphalt 8, Dragon Realms, turned the music on on the Play music, Hangouts,Facebook, Google Currents, Chrome, and music tuner in capture mode, and I am able to switch between them seemlessly. I opened settings and it jumps to 719 MB RAM.
On the other hand I faced some weird lag on my N4 these past days with KitKat. I must say I already forgot how laggy Android was long long ago, and now I am forced to remember it.....
Stock 4.4, not rooted yet (for observation purposes)

Even my tapatalk app seems to get killed off all the time.

This is a huge problem, can someone confirm if this is only on nexus 4 or even on the nexus 5 ?

Hmm maybe it's not only using 512mb... but mine reaches 1gb and kills stuff off relentlessly.

I just loaded around 11 apps. After switching to the first app; it refreshes. My ram never reaches 1GB.

Could it be something kernel side? I'm on faux kernel.

Now that u mentioned i checked on my phone .. i am on stock rooted.. my ram doesnt go above 600mb howmanyever apps i open it reaches 600 mb and then starts killing them .. this isnt cool ..!! now i understand why my apps restart on me sometimes .. this is a screwup .. whats the point in having 2gb ram and not getting the benefits out of it .. kitkat is supposed to support 512mb ram .. not make the max limit of the phone 512 mb .. hope this gets solved!

Can someone on stock do a backup then test faux kernel or some other kernel see if it's the same? As i sai mine reaches about 900-1000 before it starts killing off i still think this is a bit low. 2gb of ram so why not use it it's being wasted.

In stock is confirmed. Sometimes you can get up to 680-700 but then in some seconds they get reduced up to the 500 again...
A friend of mine has a Nexus 5. He did the same test and he get stable usage of 1Gb and no tab refresh/hangout re-start..
It is clearly a Nexus 4 issue. Final proof:
https://code.google.com/p/chromium/issues/detail?id=322336
They say that it is logic management problem of android... Chrome has nothing to do except being so heavy... But it happens with lots of others...

I can also confirm this
I can also confirm this on Stock Nexus 4 Kitkat (Root).
I did not notice this before, since apps were loaded so seamlessly and quickly from cache (Is it because I'm using ART?), but Chrome gave it away since the tabs are refreshed.
It starts caching apps at ~800+ MB usage till it reaches ~500 MB.
It doesn't bother me performance wise, but is there a way to change the memory limit other than 800 MB on a rooted device?

Do you Know any custom kernel that allows this better usage?
The less intrusive possible since stock is fine for me except for this...
Faux? Semaphore? Another?

Im using semaphore but mine is same. Hangouts gonna restart, chrome refresh and launcher redraw. Maybe Google will fix it.
Sent from my Nexus 4 using xda app-developers app

i think your problem maybe related to OTA update .
i'm okay with Stock rom with factory image .
but i use franco kernel .

No wonder the kitkat makes my phone lag a lot.. Even apps like Facebook and whatsapp take time to load and lots of time to scroll.. And chrome gets stuck every time I scroll..

nexus s low mem info

hey guys...so I was playing with the phone, installed some apps here and there and went to mem info and i saw that my available memory is never over 70 mb off the 345 !!!!
this might be causing some lag and maybe overwork the processor and messing with my battery life
I moved most of the apps to the usb part and still...I reset it..went up but then drastically went down again
Im running superaosp 8.6 .... I have no idea why is this...MY nexus one there was always at least 100 mb left (used app2sd)..kinda annoying to be honest
any advice?
If you go through the list of running apps and services, is there anything out of the ordinary?
Try to close all of them and see what happens.
Greetz
PS: I have about 180mb free if I only let the vital stuff running - Google services, BLN, Maps (LocationService) and Swiftkey
I've got 156 MB free on mine.at least that's what the running services screen tells me.
However android optimizer tells me that I've got 35 MB free? What's going on? Is the stock android running services panel not showing everything?
Sent from my Nexus S using XDA App
^^^exactly my thing...On the running services are it shows about 140 free but on thememinfo i have about 50...really weird
Another thing ...my battery usage goes :
display 40 percent
isnt that a little too high??
autorotation off, auto brightness off
Well I think on the running services it probably only shows you services that are actually running (actively). Whereas other programs (such as android optimizer) tells you the memory used by all programs that have been started at boot time.
I'm now just guessing here but many of these boot started programas might have been passivated by the Android OS onto disk so they don't really take actual RAM until you switch to any of them. Only to get passivated again after you exit them.
I get 40% usage of screen as well. It's normal, it's what takes the most. I've got auto brigthness on and it's usually quite dim. Auto-rotation is always on.
I would only get concerned if the Android System starts taking much battery use, rising above 10%. This might indicate some program misusing the system and keeping the phone awake too much.
Go Weather had such an effect on my Nexus S so I switched it off. Other programs that track your location in real time (like some weather programs... Weather Bug, but can be configured) can take a toll on the wake time of the Android System.
running services shows my device having 234mb free ram

By saying "moved to the USB part" do you mean you moved most of them to the SD memory? If so, doing that will make your Nexus even slower. Memory and available app storage are two different things. I think you're confusing the two.
Nexus S and NS4G have:
1GB of app storage
16GB of SD storage
345MB of RAM
Also, having low memory available actually means your system is properly alocating all available recources. Do some reading on how androind manages memory. It's definitly not your typical Windows scenario Another thing to keep in mind is that RAM which is reported isn't accurate to what the usual "free memory" ideology is.
Awesome answer sir!!! Thank you..it def help me understand some of the stuff.still a little confusing tho
Nexus one and s are def little different from each other

Yeah, they are different but besides the specs same rules apply. SD storage will be slower to respond than internal app storage and ram is filled up just about the same way.

WTF with the ram

i can only open about 3-4 app before my ram is full and its forcing to closing app . seriously ? wtf is this .
i feel like this phone is worse than n95 .
if i open a web page one youtube link and i still have in memory my message app it will start closing app and sometime it even close the Touch wiz widget so they have to re appear and load for 4 second . i cant believe they only putted 1gb of ram with all there touchwiz bloarware.
Ram issues
Check what apps are running on the background, i would check primarily things you log into that are always logged in like FB, Gtalk, Skype. although even with all those running you shouldnt have issues, maybe try doing a cache and dalvik cache wipe reboot and check changes.
MY BEST FIX is rooting, flashing an AOSP based rom that normally for me they use 350 to 400mb on a normal basis instead of 550-600mb in a sammy based rom.
mine is usally 800-1g and im constantly clearing memory. I dont get it either.

I agree, I just opened every app i have and went up to 1.26gb.. and when i have no apps open it jumps from 800-1gb on its own.. so i guess its all in the system that takes up most of the space

Jeez 1gb is more than enough
Problem is with the Samsung bloatware. Kies, Remote Controls and all those other services. Delete kiesexe and freeze the Samsung crap inc SVoice..
I see no need to sync to Samsung and Google. The Google services are enough.. The Samsung store is only worth unfreezing for those free offers. The four tracking services ain't needed etc I use Avast to do that etc.
Getting 285M free apx after bootup, same as ICS, on 4.1.2 now. 12 widgets, FB, G+, Fancy widgets, Jorte etc
Also make sure not to run supercharger. It kills multitasking!
Disable all the Bloatware or freeze it using link2sd.

Still sitting between 540mb and 630mb maximum

My 2gb i747m really makes use of the extra ram. It not only can handle 50 background apps with stock rom as apposed to 15-20 for the 1gb version (assuming there is enough ram), but it will boot with about 1.6-1.7gb available, about 700mb used, and 1gb free, and will use memory up to about 200mb free before killing apps to make room for new apps. Bottom line, it multitasks like a S.O.B. My opinion based on 2.5 years Android experience...is that 2gb ram helps big time...especially if you do not optimize your system.
If I had the 1gb version, I would consider a lighter rom as some have mentioned, but also the V6 Supercharger app with specific settings to allow maximum multitasking while remaining stable...which might take some experimenting. I would install Titanium Backup Pro and freeze as many non needed apps to prevent them from loading at boot and using up precious ram. Also, for some apps, I use AutoRuns to prevent them from loading at boot time.
Also remember...that some apps will stay in RAM when it's plentiful. But other apps are programed to allow Android to kill them after a certain length of idle time when they haven't been used.
Ram management is fine on the S3.
If you are not happy with it use a task killer, custom rom/kernel and/or supercharger v6 script.
Also if your ram<100 then you should start making complaints.
My free ram is at 120mb-160mb and i'm happy,no lags,no slowdowns,nothing at all.
Android preloads apps in memmory in order to open faster when we launch them.
Free ram really is wasted ram...it cancels multitasking and if you've bough a 600$ phone and can't multitask with it then you're worth of your fate.

The fact that an user has to get task killer and manage memory by him own: FAIL!
I know android pre loads stuff in memory, but it got the priority all wrong.
Why does it keep killing msging, phone and the GODDAMN launcher .
While it never kils the stupid stuff like "Google Book mark Sync", unless you freeze it.
There's no denying that 1gb has crippled S3 badly.
You can claim "Free ram is wasted ram" and throw down links, but at the end of the day it is giving me a bad experience.
Case in point:
1) Launcher Redraw:
Two points to it:
->Bad priority (I'm not sure if it's either a Samsung fault or Android; OOM 6 isn't the way to go).
-> Less ram.
The fact that browsing through play store for 15 mins and then hitting Home button results in launcher redraw is pathetic.
Less ram is the culprit( atleast one of the).
On such an expensive device this is just EPIC FAIL.
Sure we can do Super recharge and try removing the bloatware, but these are quick fixes and doesn't get rid of the main problem.
Not to mention not every one finds all this stuff easy.
The fact that you have to do tweaking on the 'supposedly greatest android phone' to make it work smoothly is an EPIC FAIL.
Custom Roms for an device as expensive as S3, should be there to enhance functionality and increase features. Not to make it works the way it should have out of the box.
2) Sh**ty Multitasking:
Trust me, my iPod touch does better multi tasking that S3 for day to day experience. (I am not an apple troll, btw)
And it doesn't even have a true multitasking and the specs are no where near S3.
When I pause a game, and resume it after an hour it starts from exactly same place . Try that with S3.
Try to use your phone when many apps are getting updated and notification bar is constantly changing.
It'll lag the hell out.
There's no defending to these points.
This is where Apple excels , by giving user everything perfect from out of the box.
Sure you can't do much, but what ever you can, you do it smoothly.
What makes me sad is that Samsung is so close to it, yet they screwed the experience.
And I'm not even going to talk about Contacts and Phone apps.

Sorry but this is complete and utter drivel. Stop quoting websites and Google and start wising up.
If you have a game that needs to run and it uses 100mb and the phone has no free ram it kills something else.
This would be fine if the phone loaded the apps quickly but it doesn't.
Custom ROMs do not fix the lack of ram and neither do any of the memory management scripts.
My phone has around 200mb to 300mb though and it still loads and reloads phone and messaging and browser randomly.
Sgs3 is useless at memory management and anyone who says otherwise is living in a dreamland.
No lags and slowdowns is just blatantly not true as your messaging app and phone app will frequently take up to two seconds to load if you are using any Samsung ROM.

True that.
I have no idea what is stored for 500-600Mb ram if not the important things like Phone, Msg and Launcher.
Useless stuff.
It is just marketing and business politics, Samsung knew that 1GB is not at all future proof but that is exactly what they need so they can sell the Note 2 and the i9305.
And still they sold over 30M i9300 devices.

Man, Android loads that stuff itself based on usage, OOM settings and Minfree values. The other stuff is services that need to run full time so that Kies sync, Location and other Samsung bloat that is really not doing anything most of the time.
Ya I know.
I wonder how can the most important thing, launcher, has an OOM of 6.
Stupid really.
Is it a fault of Android or Samsung messed it up.
In all the galaxy nexus videos I've never seen launcher redraws.
So maybe Samsung messed up for whatever reason.

that remark has been misused greatly by people that can't code for ass and fail at memory optimisation.
It was originally in reference to the Superfetch feature in Vista/7 storing frequently accessed data in ram for faster application startup. It wasn't meant to be applied to applications that use huge amounts of memory for no good reason.
much of Androids poor memory management is Java related, who knows, maybe Google will get a clue and dump the Dalvik VM eventually for a native operating system.

Nexus 10 memory leak

I got the new Nexus 10. Haven't installed many apps. I noticed that if I watch youtube for over an hour, youtube crashes back to main menu. Then I noticed that the entire tablet turned extremely sluggish. I went to Apps in Settings and everything wast in the process of Restarting! Also, almost the entire RAM is used leaving between 40 - 90 MB's of Ram free!
I tried to take a screen shot of the situation. But apparently there's not enough memory to save the screen shot!
So I had to take a pic of the tablet with my cellphone.
What's going on?
Details:
Brand new (less than a few weeks old)
Android 4.2.2
Non-rooted
Nothing running in "SHOW CACHED PROCESSES"
The 8 apps running continually "Restarting"
I force close the apps. But even with only Settings and 2 system apps in the "Restarting" state, the memory is still 1.2Gb used.
i thought this was independent to custom roms, as I've seen this happen on my aokp running gnex. it must be a bug in 4.2.2. hopefully it gets fixed officially, as most recent OFFICIAL builds of AOKP have already fixed the issue. something about the camera on the lock screen or something i read a while back. the only fix right now is a reboot.
I have a similar issue, I'm running nothing more than stock apps (besides Os monitor and terminal emulator) am not rooted and stock ROM.
What I have found is that surfaceflinger is just slowly using up all the free ram where it gets to a point that the devices becomes unstable.
Install os monitor and see if its the same for you?
** was trying to post a screen shot of my device showing surfaceflinger using nearly 700mbs, but I can't post links.... sucks)

no worries buddy, I got surface flinger growing in ram over less than a half hour cycle. just for my two cents, I've seen it start off with 60mb used, but these shots are a little after some web browsing and about 15 mins of sonic 4 episode 1.

look at RSS. most of those were ran with just the tablet idling on the terminal screen. and this is also across different kernels and Roms. I hear something about aokp fixing a nasty leak but I haven't tested yet if this fixes it yet.

It's not fixed, at least not completely. It does feel that surfaceflinger eats the memory slower on AOKP but nevertheless it still does it.

Should I root my nexus 10 and install a custom rom? I don't want to be having this kind of problems, I saved money to buy this **** and now it won't work, I put my faith in you damn nexus 10 .
I am experiencing the same memory leak on stock rooted 5.1.1. It is very painful to say the least. In my nexus 6 I'm having memory leak as well but there is 3 gb of ram so it's not as bad. Did anyone find a work around or a fix for this issue?

[Q] Memory Leak? Avoidable?

Just decided to use my Nexus 10 after about a day or two of inactivity, and I noticed it was real sluggish. Went over to Running apps, everything shown there is Restarting, and there is only about 77MB of RAM free.
I've had this happen a few times I believe.
Is this scenario avoidable in any way?

Free RAM isn't usually a problem: Android will cache things in memory to help them load faster, so normally seeing <100mb of free RAM isn't anything to be concerned about, and will not affect performance at all.
The sluggishness and "restarting" services sound like something bad, though.
First, make sure you aren't running any kind of automatic task manager/killer. Next, after restarting your device, keep an eye on that running services tab in Android settings: apps. See if any of them seem to be growing in RAM use disproportionately to the others. It may take a few hours to show up.
I suspect you have one bad app with a leak causing low memory to force the other services out of memory.
Even after caching and such this tablet should normally have 400-600MB of free RAM though. The low amounts definitely come from a memory leak. Right now the general consensus is that it cannot be avoided because it is a problem with the GPU driver. How much truth there is to this I dont know. I do know that I myself did not have performance issues or memory leaks when I was back on 4.2.1 running CM10.1, so I still feel like something in 4.2.2 introduced a memory leak.

Even after caching and such this tablet should normally have 400-600MB of free RAM though. The low amounts definitely come from a memory leak.

It is normal and expected for free memory to dip lower than that during normal operation. It is simply inaccurate to tell people otherwise.
I would caution against claiming something is "definitely" anything with so little solid information.
It might be that there is a memory leak, but it is much more likely to be a user app than a kernel memory leak until there is hard data saying otherwise. As of now there is only one highly subjective user report.
During operation yes, but when you pick it up after days of the tablet idling with nothing running?
There is plenty of solid information if you have looked around the development threads with all the activity trying to pin down the memory leaks everyone is having, to say one doesnt exist just shows how little you have been getting around the threads.

Free RAM isn't usually a problem: Android will cache things in memory to help them load faster, so normally seeing <100mb of free RAM isn't anything to be concerned about, and will not affect performance at all.
The sluggishness and "restarting" services sound like something bad, though.
First, make sure you aren't running any kind of automatic task manager/killer. Next, after restarting your device, keep an eye on that running services tab in Android settings: apps. See if any of them seem to be growing in RAM use disproportionately to the others. It may take a few hours to show up.
I suspect you have one bad app with a leak causing low memory to force the other services out of memory.

Nothing in Recent apps, I had all my usual apps installed. Most of the time when I'm doing nothing I have hundreds of MB of RAM available as free space.
No Task Killers either. Couldn't even open a game I had (would instantly go back to launcher, no FC message) or take a screenshot even.
Just my personal experience, but I have owned my N10 since December and frequently let mine idle for days and have never come across this issue yet. Memory on mine is usually above 600MB everytime I check it in the Apps setting, I don't think I've ever seen it go under 100 since I've owned it, and I do go in there a lot to force stop certain things that autostart. I am leaning more towards what ZanshinG1 said that its a rogue app installed thats eating it

I suspect we have different standards for what qualifies as useful information. Let's just leave it at that.

Do you have any apps which use OpenGL ES running? Games and live wallpapers are the usual suspects.

Nope, nothing was open at the time, and had a normal wallpaper (non-Live).

For the record surfaceflinger will eat about 100 megs per hour of video when you watch YouTube through chrome. I've duplicated this on stock, CM, mrrobinson AOKP, and raspbean. At about 600 megs the tablet will start misbehaving, closing apps, being sluggish, keyboard won't come up in chrome when you go to the address bar, etc. If you can stand to wait it will eventually reboot usually when idle in my case. Oddly enough the YouTube app doesn't produce the same results on the same video.
The usefulness is debatable. The facts are not.

Hopefully ROM dev's will add some newer AOSP commits to their ROMs too, such as:
Fix a minor leak in dvmCreateInlineSubsTable (commit to aosp)
minor leaks caused by failed initialization in JNI_CreateJavaVM (commit to aosp)
Fix a minor bug in dvmCreateInterpThread (commit to aosp)
Fix some leaks in VfyBasicBlock & BitVector (commit to aosp)
But it is probably a rogue app.

Chrome?
So for s&gs I installed naked browser and I'm not seeing the climb like I did with chrome. After about 4 hours of YouTube it went up 4 megs instead of 400 megs. I just saw another user seem to confirm this too.

I don't watch videos from Chrome, and it wasn't open at the time either (I may of opened it earlier before I noticed the memory leak, but I know I swiped it away from Recents when I was done with it). I didn't use the YouTube app either.
Had it occur again, although it wasn't "as" severe since I was able to load a game and take screenshots this time; performance was definitely slower though...
Running Apps:
Cached Apps:
Maybe run PS in terminal the next time and grab a screenshot. Then after reboot or return to normal do it again and compare usage?

I have my tablet reboot every night at 4am with Tasker-Secure Settings plugin. Maybe not a fix for the issue at hand, but enough to make this problem go away permanently and reliably.
Easy fix: don't use trash roms like aokp or cm
I personally use team eos and ktmanta and the system runs super smooth with no memory leaks what so ever. After 32 hours if I clean all apps I got 600 or 700 mb free.

Wow. Talk about trash talk.
I've never ahd this issue on AOKP or CM, have on PA... I did enjoy Eos when I used it but found RootBox had the features I needed. Then again... I reboot every few nights typically. My mom leaves her Nexus 7 on for weeks on end with no issue, but its not a 10.

I don't consider rasbeanjelly trash...
I think I've run into this bug once, after a couple days of usage, likely mostly inactive without charging. I noticed that everything I tried to do was really sluggish and once I saw all the apps restarting in the built-in task manager, I figured something was seriously borked, so I rebooted the tablet and it was back to normal. Given all the other stability problems others have reported with this tablet, I'm glad just a very occasional reboot like this is the worst of my problems. :victory: I'm running stock Android 4.2.2, with only a handful of apps installed, probably more default apps uninstalled than apps added.

[Q] Note 3 RAM consumption

By default (no additional apps installed yet), Note 3 consume almost 1,4GB of its RAM. Is it normal? Can we disable or uninstall some useless apps/services from it? Any recommendation? I need more free RAM to run other apps.
Device doesn't manage its memory well enough for you?
this beast suck a lots of memory, i ran only few apps memory remain at 400mb free WTF, when i clear memory i saw it clear 40+ apps ,so it look like many samsung junk apps run in background.
-No custom for me at this time, i'm not big fan of Omega Rom. Wait for more custom rom.
Why wouldn't you want the device to cache Apps in RAM?
RAM is there to be used, not to be empty so you can see a big non-utilized number. If new opened applications need more RAM, the OS will automatically clear the old stored data to make room for new ones. It even explains this in the task manager if you bothered to read.
RAM is indeed to be used. But it's not pleasant to see your rebootet phone is slurping up 1GB of ram immediatly.
I've rooted mine and loaded up Omega. I deleted all useless apps. I'm running now on 500 - 700MB after booting up
This means for me less bloatware and more private apps that I downloaded can be cached
Win-Win Situation
After clearing memory I have a gig used somehow and it's pissing me off to be quite honest cause I can't work out what's using it all

I'm with MohJee here; Android is just using as much memory as it can because it's faster to access the RAM than the storage. The boot processes use RAM, and if there is enough RAM in the system, then the boot processes will just use that RAM in order to avoid swapping, hence helping the device boot faster. The amount of 'free' RAM you see after system boot is just the RAM that was not used by the boot processes; the 'used' RAM is not necessarily being used by active processes. It looks used, but it's in fact free to take.
Whenever an app needs memory, the OS loads it up in RAM until there is no more RAM available, in which case the OS will just clear some unused memory to make room for the new app. This is more efficient than cleaning memory as soon as you leave an app, because then if you reopen an app you closed a while back, you don't need to load all the data in memory, it's already there.
Basically, unless you run a lot of processes or you have very little RAM, the RAM being full is a good thing in the Android world.
The RAM should get used in any Android device, with 3GB of ram, it seems like the phone is caching almost everything it can, it doesn't seem to affect usage as it kills non used apps and loads the ones you open if it reaches the limit.
This is perfectly normal, and how it should work.
Im suffering the same .. my Note II usually consumed 600-900MB but my Note 3 suffers 1.3-2GB smh. I'd be grateful if someone gave me a valid solution ^^

I'd recommend reading the 2 posts above yours.
I am having launcher redraw issue. Could that be due to high ram usage?

1.2GB after doing a lot of things, drops to 700MB if I clean using Taskmanager.

Yea, upon a reboot it only has 689MB in use. Even running 6 apps at the same time (Tapatalk, Firefox, Gmail, Outlook, Whatsapp, Oh!Edu Towns) it still sticks to about 1.28GB In Use.
All I did was clear out the bloatware as much as non-root allows, replaced Touchwiz(480MB usage) with Apex(68MB usage), turned off all sync and location services, and I don't use Facebook.

2.66gb max?
... samsung screwed with us claiming the 3gb bs.
they loaded a bunch of **** that constantly loads. all their dumb software screwing with the consumer.
So they give more, and reserve almost half a gig or more on some devices.. the North American has a max of 2.38gb so reserved a lot more.
the note 2 had max 1.75 but less crap loading in the background

Even If they put 5gb, 4.77 will be full. Phone doesnt get slow, however I have launcher redraw issues.
