Hi Guys,
I am on ICS 4.0.4 and my S3 shows 779 MB, which is always busied by 680 or so!!!
I checked an S2 with ICS 4.0.4 and the memory is 830, and is busied by 450 on average. (S2 has larger memory than S3 on ICS4.0.4???)
So what is wrong with the S3 memory? i keep on killing apps all day and night to bring it to 450 or around, I dont have too many programs, and, i am not using except two widgets, checking on the background processes annd programs, most of the system's stuff is running on its own, even if i freeze some using Titanium pro.
Anyone has the same problem (if i can call it a problem?!) is that normal??!
Why would you consider it as a problem? Android is best at multitasking. You don't have to kill apps, its the nature of the beast so to speak to have a semblance of the apps running in the background for your convenience.

Bigger screen and stuff like Smart stay and S voice eat up extra Ram.
Yeah it's really dumb to kill apps and clear ram the whole time, phone will feel sluggish because it needs to fore up stuff all the time that would normally sit kindly and wait for you in ram... You are making your phone slow and killing your battery

Okay, i got it, No more killing APPS , now the question is, how come the S2 has more overall ram than the super S3, on ICS4.0.4??? considering the 779MB to the 830? its just a noob question

i flashed mine with stock I9300XXALF2 now my average ram usage has dropped by at least 150mb & is much snappier on the home screen redraw

Thanks for the tip, im kinda new here, i am trying my best to read on before getting bullied by someone like up there but, eh, still not doing it right.
Anyways, i found two posts, one about a stock ALF2, and the other talking about deoxed and oxed .
What is the difference between :

Bullied?
Try reading the rules before posting. Rule number 1 is search before asking a question. Now you're asking the difference between odexed and deodexed... Do you seriously think you're the only person who has asked this? It's discussed EVERYWHERE!

Deodexed ROMs have their .apk's (which are basically the application packages) repackaged in a certain way. An "odex" can be thought of as a collection of parts of applications that have been pulled out and optimized before booting. This speeds up the boot process - in a way, it preloads part of the applications - but it also makes hacking those apps difficult because part of the original code is already extracted somewhere else.
Deodexing is just a process of putting those pieces back into the original applications. It takes a while to extract those parts and build the .dex cache (aka Dalvik cache), but only because the relevant parts aren't in an easy-to-access place for the system. The advantage of this is that an app can be modified effectively and the developer doesn't have to worry about conflicts from the separate odex part of the code.
So, short version: "Deodexed" ROMs have all their apps put back together. If an app can be themed, for example, a deodexed version of that app will not get messed up when the modified .apk tries to mesh with the odex of the original un-modified .apk. Because it's not there.
If you want an aftermarket theme, you need a deodexed ROM. I'm not sure if deodexing can be done to individual apps within a non-deodexed ROM.
The search on the site is horrible. I use Google and type xda after anything I'm looking for

I suppose "standard ROMS" have no apps or anything in the "Dalvik cache" ? (as all apps have "stand-alone" APK's ?) ... correct ?
well, I guess its widely know how android manages memory, and clearing ram is more of a performance inhibitor than a booster. I gave up all hope when I took my s3 to the service center and was given the solution of clearing the RAM repeatedly to solve the horrible ram issue.
the problem i was and still am facing is, the ram usage increases automatically within few hours of usage with hardly any apps installed. its extreme as it crosses 790mb and stays in that range. whats bad is apps keep on restarting in the background, phone slows down terribly ( switching between apps, moving out of an app just to stare at the app drawer 3-4 secs for all the apps to load, even the keyboard takes time to pop up). So moderate ram usage is good, but high ram usage is bad especially when it causes to slow down basic use. now what problem i am left with is deciding whether to root and flash a custom ROM and void the warranty on my one month old device, as both the times i revisited the service center the only thing the guy did was format and reload the firmware, which didn't solve anything. this was prevalent on stock ICS as well after the JB update via kies. as a last resort I am thinking of trying an official firmware from another region. as Indian one was causing the issue. my friend got his s3 from saudi and he hasnt had such severe problem(certain sluggishness is acceptable on a bloated stock firmware). so i am thinking of flashing that firmware. is it safe to do that? and i wouldnt need root access for that right, only odin and the firmware correct?

Generally RAM usage depends a lot on running widgets.
I personally use only one widget on screen at all times. (Google search) which is enough to get the job done for anything. And I run only 3 home screens
I would usually have about 200 free ram
Also Im on Omega 34 rom which is by far best (In my opinion for RAM management). It automates in such a way that 200mb ram is free at all times.
I really dont care much about warranty ,the first thing I do when I get an android device is to root it. (You do know you can unroot right ?)
So if RAM is really so important to you its best to root.

yes I am well aware of rooting/un-rooting and other basics, had done all that on my S2(i9100), also found it more fun and efficient than stock but time is the only factor that's stopping me from experimenting. and thanks for the omega tip. I am certainly going to flash a custom ROM, after trying out few official ones, When I do, I would definitely go for Omega, alot of people recommending that one.
Omega is good as is WanamLite, Foxhound and Hyperlight. Smoothest I've used were Foxhound and Omega although I'm running WanamLite at the moment. Smoothest version I've used.

Just what it says. I've had my Galaxy S3 for 4 days and I've noticed that I only ever have about 100mbs (out of 800) free on my phone at any one time.
On my SGS2 I have over 300mb even with many games/apps running.
Sure my SGS3 is far faster than my SGS2 but when it comes to Web surfing and watching flash videos on pages, as well as just browsing around the home screen sometimes the phone gets so low on memory that it just starts to randomly kill apps that I have open. Apps like: Avast (which I don't use for the Anti-virus but for the extensive Anti-theft protection), Viber - which I use for making and receiving VoIP calls and Tasker. Which I use for automating things.
Surely a phone like this needs RAM I'm sure. But leaving me with just 100mbs spare for everything else can't be right can it?
I don't have many things running. Just the normal stuff. The main point is that my SGS2 could easily handle all this.
Anyone else having the same problem? Is there anything I can do? I use the Opera Mobile (not lite) browser.
I'd be happy to provide more information if needed. I'm pretty gutted over this. Battery life is lovely but the phone's performance grinds to a total halt when it clears its RAM... Which I never did manually on my SGS2 because it drains battery when it caches everything instantly again anyway.
Thanks so much in advance.
P.S. I can't find a 'task manager' app anywhere. I know if hold down the home button that I can access the task manager by pressing 'task manager' but that doesn't show me anything useful like what the SGS2 does. I can't exit apps or see how much RAM and CPU they are using or anything. Does the SGS3 really not have this option??
Touchwiz for s3 is heavy! Normally you shouldn't worry about ram on Android but touchwiz is really little much... I would recommend cm9 maybe.. Lightweight and fast

Surely touchwiz can't be that big of a RAM hog. I have 4.0.3 on my SGS2 how can 4.0.4 be so much worse?
Edit: Obviously free RAM is wasted RAM but did you even read my post at all??? My phone keeps running out of RAM and killing apps, then reloading them instantly which slows down my phone to a halt and excessively drains my battery...
Ram handling is clearly flawed in SGS 3, lets hope the is no HW bug.
Hopefully future updates will fix the leaking memory.

What are you even doing here? I'm running custom rom and the killing of apps is gone.
To those people spamming about "free ram is wasted ram" that is true BUT samsung set their priorities wrong to start killing apps you use, since touchwiz is pretty big it kills the apps you need instead. On cm9 the ram can be used for cache for stuff you actually need and use. This dude having issues with multitasking due to bad priorities wich is solved by mods / custom roms.. If you not are willing to try that I have no clue why you ask in xda for help.

Maybe free ram in android is wasted ram, but only if the ram is used for USEFUL apps. Samsung have made a lot of stupid apps run in the background at all time, like softwareupdate, Chaton, some clud service process, AllShare Service, and a lot more (google maps also run at any given time, eating 30 mb of ram). All of this apps run in the background and take up a lot of ram, even tho I NEVER use this apps. All of these running apps, prevent the apps that I USE from being kept in the ram, and thus leads to a longer load time (f.x. Handcent SMS take a sec or 2 to load if it is not already loaded in the ram). What I did was to download Autostarts from the market and prevent these apps from starting up by themself, and thus I made room for the apps I use to be kept in the ram. However, be carefull, disabling apps from starting up (especially system apps), can cause problems!

If someone has 300MB free ram and is asking about freeing up more ram this makes sense.
If free ram is always <100mb then there's a memory management problem.
OP try disabling unused apps in the app manager, streamline startup apps and use gemini to turn off auto launching of unneeded apps.
On stock I used to have about 150-200MB free ram at boot. With CM9 and 10 i get 300-400MB free RAM at boot.

Excuse me but not everyone who asks questions in the XDA forums are idiots. I don't know what's with the attitude here of everyone with a couple of hundred posts but I'm not impressed. Knowing how RAM management works has NOTHING to do with this thread. The complaint in question here is that my phone is constantly running out of RAM and when it does it starts to kill background apps to free RAM which in turn grinds my phone down to a halt, and drains the battery excessively. Are you just here to get your post count up or something?

I don't care about if my phone has 3MB of RAM free all the time or not as long as it works without a hitch, what I care about is that my phone is killing background apps that I need open and then constantly reloading them over and over when I'm web browsing and sometimes when I'm just at the home-screen.

XDA isn't just about modding/using custom roms etc. There are multiple sections on the forums here for discussion about other topics. Including asking general questions about the device... I use ROMs on my other phones where I can because I love them and I don't mind the constant updating I have to do. But on this phone, I don't want to use partially-unstable roms that require me to constantly flash my phone over and over again just to get features that are already working fine in the general release version. There is no guarantee that this problem will be fixed in a rom anyway and some of us don't like breaking our warranty. Even if it's child's-play to return the phone back to stock settings and renew the warranty.

I've frozen all of these... 'Talkback, OTA Updates, Bluetooth (I never use it) as well as turned off NFC and a bunch of other things etc. etc. etc. I don't have that much running in the background but my phone still bounces between 330MBs (after killing everything) of free RAM and under >90. (2 mins later after everything has reloaded) To which it then starts throwing warnings and killing apps I need.

^This. THANKYOU! Finally someone who didn't just read the tagline and post stupid retorts like "This isn't Windows" etc. I thought I was being plenty clear enough when I stated that the problem I was talking about was the fact that the phone goes from blisteringly fast, to painstakingly slow whilst browsing.
Disabling ALL addons (Javascript, Flash etc). from running while browsing stops this from happening 99.9% of the time. I also removed Tasker, much to my displeasure and froze a few more apps and it seems to happen less now but I'm still hovering around the 'workable' part of my phone. Which makes me feel a bit displeased because I didn't buy a phone to be limited by what I can do with it...

It's hard to freeze bloatware when you have a bunch of people posting in forums that they don't know half of what the apps on the SGS3 do and if they are safe to freeze or not. I've done some searches but it seems that most people are generally confused about what is safe or not to freeze. Same thing happened with the SGS2. When I got it I googled (and found this place) what I could freeze and found people nitpicking over what they should, and shouldn't freeze. I have frozen everything that I've found is safe to, from multiple threads on the forums here.
I'll go and read a thread though as to why it's a good idea to flash a new kernel. I'd rather not have any restrictions as it is anyway, so that will be my next step, thanks!
------------------------------------------------------------------------------------------------
Thanks a ton to anyone who gave me the time of day and didn't just slam up some copypaste drama that has nothing to do with this thread. Free RAM is wasted RAM but when there isn't enough free RAM that background apps start getting killed (and usually instantly reloaded) then it goes without saying phone gets slower, battery drains faster, performance loss etc.
Excuse my retarded attitude but this isn't even the 10th time here I've had to dodge people who just post crap without even reading anything, and then just move on and do the same thing over and over.
I'm going to flash a new kernel, cross my fingers and freeze a few more apps, turn plug-ins to 'on demand' and cross my fingers again.
Thanks again to everyone who really helped and peace. I added thanks to you guys.

yeah. stop think like windows (even though windows 7 ram management is good). andoid load it's system/app in ram to provide faster response. but once you need it more, it will clear unused app to free more ram..not to worry about that..

Hello People,
As you can see im new to this community, i hope i won´t bother you so much.
I got an S3 myselft and unlocked it right away before even using it. Did use Samsung S3 Toolkit , which i think its a great tool and this forum is a huge palace full of incredible geniuses so i´m really grateful for what is has done for me already.
As i stated in the title i´ve been getting serious problems after rooting my phone , everything working fine. or i think it is. But the UI in general became slow as hell , it crawls on the floor , pressing the menu butom to go back takes from 5 to 8 seconds to respond onto something , no matter what , oppening applications is not that slow but switching pages or screens is LAGGY as hell. I tried full wipe , cache wipe , before and after flashing.
Actually using this rom I9300UBEMA1_I9300UVOELL1_ARO its the Non branded version of my Local Firmwar (Argentina) , the kernel i use if the one that comes with Samsung S3 toolkit 7.0.0 the 4.1.2 unrooted version for JZ054K.ELLA ( file name :boot-insecure-ella-GTI9300 )
The original Firm and kernel the phone had was the 4.0.4 "Personal" Branded BLG6 Kernel.
I know this phone is already known as a battery killer , but i didn´t spected to be that kind of slow to crawl device. I´ve already tried multiple task killer apps like AutoKill or ES task manager , Better battery stats to check battery drain but still cannot find a reason. Tried Juice Defender Ultimate on Extreme settings. And did nothing to my battery life.
Then Looking for some Customized roms i found out 2 that took my attention :
One of them is Omega and the other is Android Revolution HD, which one of these are going to have a possitive effect on performance gain + battery economy without overkilling phone capabilities ? . Is that the answer? or are there any real app / patch that could really resolve this issue.
Well people im sorry if this question sounds quite stupid or bothers some people but i already researched more than 200+ hours and i couldn´t find the exact point where i should be heading to solve this.
I would start with a fairly,near to stock Rom, I won't suggest any, just go to development and read up on the Roms, but also try a custom kernel.
Don't use task killers, they are counter productive if not used right.
I would also suggest going through what you have enabled, the smart features can heavily affect battery, also poor signal, and it might well be you need to check your modem (baseband) and see if there are other more suitable ones.
Keep reading and searching and you will develop a good understanding of various ways to make this phone fly, just don't rush things.
And, backup, backup, backup! Enjoy
Better Battery Stats and Greenify from the market may help .

Hello People,
As you can see im new to this community, i hope i won´t bother you so much.
I got an S3 myselft and unlocked it right away before even using it. Did use Samsung S3 Toolkit , which i think its a great tool and this forum is a huge palace full of incredible geniuses so i´m really grateful for what is has done for me already.
As i stated in the title i´ve been getting serious problems after rooting my phone , everything working fine. or i think it is. But the UI in general became slow as hell , it crawls on the floor , pressing the menu butom to go back takes from 5 to 8 seconds to respond onto something , no matter what , oppening applications is not that slow but switching pages or screens is LAGGY as hell.

He's right, try flashing a more popular widely used stock firmware like the XXELLA rom or the recently released ones. Also do post screenshots of BetterBatteryStats.. Kernel wakelocks are major reasons why battery drains. Often IM+Social Media apps use network data in the background and are culprits behind wakelocks.
I for one can confirm the Facebook native app as being a major contributor to the problem.
You should also check if "Fast Dormancy" is supported by your carrier or not? FD is by default enabled on the S3, disabling can save substantial amount of battery life. You can do so by downloading "Fast Dormancy Toggle App" from PlayStore.
As for custom roms, it really depends on user experience. I have used Omega rom and it easily lasted a day and half for me with good usage.
Currently I'm running CyanogenMod 10.1 and it lasts me 2 days

It pisses me off to see me and many others complain about such a basic thing as LAG in this "super powerful" device.
What is the point of all this tons of CPU, huge RAM and etc., if it cannot manage basic tasks quickly. that's great that i can play 3D games, but I want my phone to be responsive as it used to be in the beginning.
How come I need to wait for 5 seconds for my contact list to load? 3 seconds for my SMS to load, 2 seconds for an app to load in the application center. 1.5 second until it responds to a home button. You expect this kind of basic tasks to be done INSTANTLY.
So what if I have lots of contacts? Doesn't Android follow BASIC programming concepts?
That is first load the frame, then show LOADING, then load the most necessary (in that case would be the first part of the list) and then load the rest. This way it doesn't feel laggy for the user. How come it simply loads for 5 seconds without any response and then shows ALL at once.
Everything is laggy, almost anything I press takes 1-2 seconds to respond the first time. Second time is mostly instant.
Tried to clean cache of all apps, using memory cleaners, disable double home click, I am at version 4.3, using Go Launcher.
How can I find if there's a specific app that causing it? Or what should I clean to make it go smooth as it used to be when it was new? all these task managers and such don't make ANY difference. Total waste of time.
Don't mind me being pissed and thank you for your input
P.S. - My device is not rooted.
yeah....that's why i put my S4 aside and bought the G2. it's touchwiz. it's horribly optimized and has been since JB. on ICS, touchwiz was great. it was snappy, fast, awesome. it was amazing on my S3. then the S3 got JB, and it turned to utter garbage. now, every samsung phone since JB is awful.
they really need to scrap TW and code it all over again.
I'm not getting this 5 second lag. 1 and a half seconds perhaps on the contact list and I have maybe 210 people on there.
If you're getting 5 seconds of lag I think something's up. I'm getting pretty quick responses WITH Power-Saving Mode enabled. With it disabled I don't really notice anything different tbh lol.
Sorry you're having a pain of a time. If you're going to get a new phone I would suggest the Nexus 5 :laugh:
I'm stock non-rooted.

Nah, I'm not gonna get a new phone just because of that.
Could you perhaps tell me with which accounts you sync your contact list? I would assume that's related. Also are you trying it after your has been idle for a while? (it's much more responsive when I open it the second time)
Because of all the bloat you have installed...take off go launcher lol
Sent from my SCH-I545 using xda app-developers app
Go launcher is the worst. Go to the dev settings and change animation time to 0.5x or off, get apex or nova and use the fastest animation speeds, try different dialer & messaging apps. Don't use memory cleaners or task managers just delete whatever apps you don't use. Basically avoid using as much touchwiz crap as possible lol. Also know that live wallpaper and a lot of widgets cash slow things down too. I would think keeping all the stupid proximity sensor stuff on doesn't help either.

It really does suck how slow this phone is considering it's hardware. Samsung needs to hire some new people because my girlfriend's htc one is very smooth and snappy with almost no lag (minus att 's slow 4g network) I wish htc would pull their heads out of their a**es and build good phones with good cameras with removable batteries and sd cards :banghead:

I'm using nova prime as well as quite a few xposed mods including XuiMod.
All my nova settings are at faster than light, XuiMod settings are also set to fast, and I've set the transition animation scales to 0 /. 5 as well.
My S4 flies. I have no complaints at all. I've used titanium and gotten rid of all the BS too.
I agree TW has a lot going on but can be set up quite good and run quite fast. I've looked at other phones over and over again, trying to get back into flashing ROMs, but I keep landing back at my S4. It's still an awesome phone

Don't mistaken transition speed for loading/processing speed which are two totally different things. The S4 is no slouch, if it's "lagging" like you said, it's an app for sure. I nor anyone I know with an S4 has experienced this phantom lag. But then again we don't blow up our phone with launchers, widgets, or 5 different apps telling me my battery level and apps running. Try using stock everything (launchers, dialers*lol*, messaging*lol*)

whatever61, did your phone behave like you have explained (lag) when you first bought it? If the answer is no then you have an apps/widgets/or other software on the phone causing you the problem. The ole' saying 'keep it simple stupid' kind of applies here (not saying at all that you are stupid). There are only so many resources in our phones...cpu capabilities, memory etc. The resources in our S4s are pretty significant considering the size and the limited power available. It really boils down to this...the more task you demand your phone to perform the more resources it uses and at some point it has to slow down to reallocate the limited resources it has...lag. Task managers use more resources than they save...live wallpaper is a resource hog...widgets (weather, facebook, goggle now, goggle +, pandora etc) constantly updating and running are resource hogs...contracts with added thumbnails, although "neat", take up not only memory but take longer (resources) to process when you want to look at one (when you call up a contact do you want the information or do you want to look at a picture, which one of those do you NEED?)...email and messaging apps that have to sync more than a few days of old mail/messages is a waste time and resources...Samsung has put a lot of "cute" animations and gesture sensitive "crap" on our phones...they are "cute" but not necessary and use resources. Bottom line...do a factory reset, decide what you need and "keep it simple stupid". (Again, I'm not calling you stupid!!).
Don't worry, I didn't think you are calling me stupid
Yes, if I remember correctly in the beginning it was working faster (but cannot say for sure what and where was the lag already existing and where it wasn't) and what you're saying about widgets, lots of apps and all that is very obvious and very general (thanks for the input, though). The don't install too many apps or reset to factory approach is not something I think a correct approach. I bought a super powerful phone to be able to install whatever I want on it, right?
Besides an example that I provide is that when I am in the application manager and pressing on an application it takes like 2 seconds to open up. I don't think it's related to me having too many apps.
I think that I should be able to see which app is causing the lag in each case and then make my decision based on it. Yes, I can install different task managers to show me which app is taking how much CPU and RAM, but I don't see anything exceptional there. Problem is at specific actions I do, so it would be good to see what happens (like in Chrome inspect element) when I press on the action, which processes are being launched, how much time it takes for them to complete and how much CPU was used at each process. A log like that would do the job.
Besides my post was more about the wrong engineering (see the example of the Contact list lag) and the fact that many people complain about the lag in S4 and a question if someone knows about a tool that can help me find what is causing the lag (see description of the tool above).
Thanks

I don't like "stock everything", besides seems to me like stock stuff is even more laggy.

I understand your frustration and your point is well taken. I don't know of a utility/app that will enable you to clearly identify an app or process that is causing the lag you experience. I know doing a Factory Reset is a big PITA and I never recommend that to someone unless I know of no other "cure" for the problem. And, sometimes a Factory Reset isn't the cure either. But often it is. The reason I recommended Factory Reset is that it is about the only way you can (that I know of) start with a "clean" phone and nail down the app or apps that are causing a problem as you reinstall them one or two at a time. I have a developer edition S4, rooted and bootloader unlocked, and I usually will do a factory reset every two or three weeks even while running a ROM that has been debloated and "fine tuned". It usually improves battery life and the phone works smoother...or maybe it's just my imagination, but I don't think so. Anyway, good luck, hope you find the problem. Maybe some wise ole' guy will come along and point you in the right direction.

Well, for the most reliable experience, it is always best to stick with stock.
My advice is to run stock everything for a day to see if that's the problem. Your other option would be a factory reset in which I am trying to make you avoid.
Do you have 3rd party apps installed like sms/launcher/dialer/lockscreen/etc.? I can't imagine the amount of processes going on if someone had all those apps installed.

I really dont understand why people complain about this so called lag. I've had no such thing since I got my s4 right when they came out.
My girlfriend gets her S4 acting all strange sometimes too, can seem laggy. However she is constantly downloading music and she uses like 3 programs to do so. I've had to remove quite a few of those apps and then it's working like new again. Sometimes a lot of the apps available out there just aren't the best and can screw things right up I think. I've had none of the issues she's had. Mine has been fast as hell since day one. And hers is back to normal too, I just have to keep an eye on her!!

Hello guys.. I'm a flashaholic.
The reason i'm here, is because i've just realized, that i haven't had my quick fix for some time now..
Everything seems so stable, except the *mic* issue, but hey, i fixed it with a hands-free.. Otherwise, i'm very happy with my phone, it works, it doesn't use up that much battery, and it doesn't crash, you can even do normal stuff to it.
But to the point.. I really, REALLY miss AOSP, especially the theming.
I can live with the occasional bugs, though i wish it could be at least somewhat stable.. *You know, im not that picky*.
But the one thing that keeps me from using AOSP; is the camera app from Sony, because i like taking pictures of my son, and the environment..
Are there any Camera app out there comparable to the Sony equivalent?
Oh, the urge..

I have the same urge, I wanna get the full output from my Xperia Z2, feel all those four cores working in my hand. But that one Sony Camera app stops me because it's beautiful. It's matchless. That's the only reason I'm not changing my ROM and be bound to what Sony's put in my phone.
I am in the same boat here! I want to flash PA so bad especially with all their features but then the camera app, the noise cancelling features and x-reality etc is really stopping me from doing so
i use to be in the same boat before i noticed there is no point to flashing roms when im on a rom which does what i want
perhaps you should find a rom which has what you want
Same here.I literally used to flash a new ROM on my Nexus 5 everyday. As has been said though, the stock Z2 ROM does everything I want it to and rooted with some xposed mods its perfect.I just have to learn to live with my phone the way most other people do.
just a note
formatting then writing a rom to your system slows your device ALOT, it also cause alot of other issues but that comes after long wear n tear

I remember reading somewhere years ago that flashing new firmware over and over will eventually wear out the hardware and cause it to slow down/eventually fail. I can't seem to find anything for this when searching though! Would it be possible for you to shed some light on what I should be searching for or what causes this issue?
Thanks in advance!

there is something called read/write cycle life
you can only write info so many times onto a disk before it wears out and stops working
formatting a partition takes a huge amount of cycles, installing roms does the same too because its alot of data that has to write

Cheers for the reply! From what I read on the link, it says most flash memory have a P/E cycle of around 100,000 and from what I can remember, it varies depending on the type/quality of the flash memory used (Nexus 7 2012 had rubbish flash memory which a lot of people complained about). Just going off an assumption that the Z2 has a P/E cycle of 100,000, wouldn't it take quite a lot of ROM flashes before the memory deteriorates? Or is it more due to the size of the data being written/erased than the amount of times it is being done?
Sorry for the questions, I know this isn't the thread for it but it is interesting to me!

I used to flash a lot roms everyday on various devices. I didn't notice any side effects of it. As I know a little about hardware there is nothing to fear. You can imagine than one memory cell is one bit of data. If it withstands 100 000 writes it literally means that you can save data (eg. flash rom on it) 100 000 times. There is no way that you can cross this number even with everyday flashing. And it doesn't matter how much data we are writing because each memory cell deteriorates individually, so if we write on 1000 cells it means that every cell will deteriorate only by one write operation which means every cell will still be able to be written 99 999 times.
Another thing is that the storage memory in smartphones is usually one chip which means that all your data including /system partition (which you overwrite during rom flashing) and your photos and music on /data are on one physical device. The conclusion is that if you are afraid of rom flashing and wiping you should also be afraid of saving photos to internal memory. And since we are using our int. memory and change files placed on it a lot it means that we can flash roms as we please without consequences.

Thanks for the thorough explanation. I had my suspicions this would be the case and you've driven it home by explaining the whole music/data/pictures scenario. I used to flash PA and other roms on my N4 more often than I care to count but I never once saw a decrease in performance so it's good to know (personally and for others) the phone's read/write performance is not going to be realistically affected! :highfive:

Firstly, you need to face the fact that 2GB was a bad decision by Google for this tablet. There is nothing that we can ever do about that. :crying:
If you want to stay on stock, Chrome is the main culprit in consuming Ram. Switching to Habit Browser makes things better as well as changing your DPI to 288. Do a search on XDA regarding this. Whilst it improved things, it was still not enough for me.
I snapped a week ago and have now rooted and flashed CM13 and stuck with Habit. I've been using a few days now, and for the first time, I can keep my 3 Fantasy Premier League Tabs open, (they are huge,) without constant refreshes, redraws and lag. :victory: Right now, I feel for the first time, I'm getting what I paid for and the Nexus Experience. The only bug so far, is that always listening doesn't work.
If you've just bought this tablet, I'd consider returning it if you are not prepared to root. The performance will never be acceptable on stock.

My Nexus 9 is running slow most of the times and it takes while to I switch between apps or open an app most of the times...what is the fix for that? I have been trying clearing the dalvick cache several times but no help...and I really don't have lots of apps. Thanks for your help in advance.

Clearing dalvik cache will do precisely ONE thing and ONLY one thing; make it take a long time to boot next time as it regenerates it.
Ignore the amount of available memory. People who are concerned about the amount of free memory are trying to apply bad mswindows knowledge to Android. Totally different and no comparison. UNUSED MEMORY IS WASTED MEMORY!!!
So here is how memory management works in Android; it *preloads* everything that it thinks you are most likely to actually use, so that when you DO use it, it is more likely already loaded and starts up very quickly. If you are switching to something that is NOT already loaded, then it just needs to dump lower priority programs out of memory, which basically only takes a few nanoseconds (billionths of a second). So that is NOT it.
If your device is acting slowly, then you need to figure out what the actual cause is. Trace the CPU utilization with something like the "top" command (the one with busybox is a lot nicer than the one that comes with Android) while you are experiencing slowdown. You can also look to see if there is excessive I/O happening (i.e. read/write to the internal storage), and of course, some software will require a network exchange before it will start up -- nothing you can do about network lags.

try flash custom kernel..the memory management is very good with custom kernel

Thanks. I am still on the official rom, I probably should switch.

Try tapping on 'Memory used by apps' on that memory settings screen, should let you know what the culprit is

I have done it several times. As I said, I really have not so many apps and just the very common google apps are installed.

Thanks for your reply. Yeah, most of the times, the slow down happens while I am in chrome and browsing..it actually is not snappy at all in internet browsing...however, I remember it was back in the days that I had bought it.
No, I have this Nexus 9 since last May I think, but have not yet found the time to root it and flash a custom kernel and rom . Anywyas, I have done it previously for my other devices, so not that much rookie in it. Probably will give it a try,

Thanks for your kind reply and explanation.
I think that is exactly the problem as even sometimes switching between the apps that I have just opened is also so slow and the nexus lags badly....Yes, I am aware of the network lags, but the problem I was talking about does not have anything to do with it...I will try the command you said, but can I run it on stock rom? I have not yet rooted my nexus nor flashed a custom rom.
Thanks

You can do some investigation by watching the processes and seeing which are taking the CPU and memory on stock. The problem is, when you find out, there isn't much you can do about it.

Its quicker and easier to just install a custom rom where this type of work has already been done for you. :victory:
Lately, I've discovered that loading Chrome immediately raises my CPU temp by 30+ degrees. Sometimes that's enough to make things run really slow
Yeah, I agree...I will try to fimd sometime amd go over flashing a custom rom. ??
Yes! I habe noticed that these slow downs mostly happen when I am browsing in Chrome...
Web browsers are DEFINITELY a source of slowdowns.
The problem, more often than not, is actually *javascript* that is written by MORONS. Even on a desktop machine, you can watch the web browser for CPU and RAM utilization, and it just grows and grows and grows until you finally kill the process and start a new one.
What this may come down to is actually quite simple; the CPU in the Nexus 9 is actually more suitable for use as a stovetop than an actual CPU. These things get way too hot way too fast. If you beat on them with a web browser, they'll get hot and throttle down to low/verylow frequency, which will make them generally unresponsive. So if that is what is happening to you, there really end up being a few options to deal with it;
1) disable javascript in the browser,
2) don't use the browser,
3) improve the ability to disperse heat from the CPU.
For #3, you may note that when it gets hot, it is pretty localized to the corner of the device up near the power button. An easy solution to distribute heat better might be something simple, like adding a layer of copper foil to the inside of the back cover. The thicker the copper foil the better. Copper is very good at conducting heat, so this would spread the heat around over the entire area covered by that foil. http://www.ebay.com/itm/Copper-Foil...nductive-Adhesive-Ship-from-USA-/162018486132
I also found chrome was slow starting up, switching tabs etc. Found that logging out of my Google account in chrome improved this. Seems that synching tabs etc triggers the pause. This might be an acceptable workaround for some but I appreciate it isn't a great fix if you want to use that feature. Actually I'm not bothered as I think Google know too much anyway. �� But the underlying problem is this tablet... I don't have this problem on my phone.

Yeah, they do get hot...and the browser is the problem, I agree...however, I think they are not the main reason...there is something wrong with low memory or maybe some apps...

I don't agree with that.
We use our N9's *all of the time*, and there is never any perceptible slowdown. Possibly with the exception of straining them with web browsers, but web browsers are... poopy... on EVERY platform and device, so that doesn't really stand out. Typically just minimize the use of web browsers and all is well.
Web browsers were good in 1996 when they were simple things to display an html website. Since then, they've added all kinds of useless crap to them that bloat them out, hog up tons of memory, and just generally make them into a useless waste of space.

I know..but everyone knows that N9 should be faster!...

Update:
I think I have kind of find the problem of low speed of my Nexus 9...I uninstalled an app that was for weather prediction and from that time on my Nexus 9 is very fast and responsive...No problem so far. I also uninstalled some other apps alogaide that which I was never using them,so I am not sure if the weather app was exactly the reason of the slow downs...but the other apps where just some games or some simple apps....well, I hope this information helps! Let me know your idea. Thanks everyone
