I have around a strange persistant problem.
I have around 250MB of internal app storage space left and used about 650Mb of storage of apps on my external 32Gb SDHC card.
I am using autostarts and task manager to manage the start up of apps and stop things running which works really well at prolonging battery life to the point where I reach a good 14 hours with heavy use on battery (I have five e-mail accounts pushed all sorts of widgets and use the phone fairly heavily on an average day, admittedly I get a little less if I use multimedia to any extent) I am using a stock 2.3.5 build from which I have removed some bloat stuff so I have about 35MB of rom storage left. It's rooted and has CWM installed etc.
In total I have something approaching 650 app elements in Titanium Backup depending on what I do or dont have installed at any given point.
Without the SD card the phone boots fine everytime. With the SD card in depending on the amount of .asec files in the .android secure folder the phone will often boot up and then during the processes after boot semi crash. By this I mean it will boot up then about 2-5minutes during the afterboot it will stop working and drop in a loop where it is still trying to run after boot process like scanning for media and stuff but loses connection with the carrier and then loops. Removing the sdhc card and moving some of the .asec files out of the the .androidsecure folder usually fixes this. It does not come up with safe mode or anything like that.
Has anyone else experienced this? Have I simply reached the limits of what the phone can do? My guess is that the problem lies with the process of copying/unpacking the .asec files into the /mnt/asec structure?
Can anyone offer any useful advice the 32Gb SDHC card is only class 2 (all that was available when I got it) I am thinking a faster one MIGHT solve the issue but that seems only a possibility and investing in a new card simply to find out it doesnt fix the issue would be a relatively expensive mistake. Has anyone else found similar limits?

Not exactly helpful... Its far better to have a decent descriptive long post than people who writes "I have tons of apps but I get problem with connection".
@op I also have a tons of apps, fairly close to the amount you have, but still have quite a bit of space left, do you make a lot of backups and such? Check your SD card, because I remember a post here saying that deleting files within the lost folder can save space. (some people lost GBs, some just a few MBs) Best if someone here can confirm its safe to delete the files within though.
A known problem with some phones is 32GB cards some work well others dont some phones play up others dont .64GB even worse .

Hmmmm seems like you are stressing the filesystem's/IO scheduler's timeout limit to the max with a class 2 card.
I would recommend you doing two things:
a) You have your phone rooted, try installing SiyahKernel, Voltage Control and change the I/O schedulers - thru set on boot -> init.d script (try alternating between noop, sio, bfq and VR), if that still doesn't help, try adding Thunderbolt Scripts as well - especially the remount script via script manager (links in my sig).
b) Try a different rom perhaps? Stock ROMs are not the most optimized things under the sun in terms of SGS2... back up your media to your PC, do a nandroid/titanium backup to your external sdcard and try flashing another rom. If it doesn't work, you can always restore the nandroid.
Hope it helped somewhat ^^
Thanks for the advice guys, think I might see if I cant test a faster card off a mate see if that helps.
Otherwise I will try that syrah kernel and scripts, not too keen to go for custom roms my experience of them with the galaxy s was they all seemed to have a major bug that I couldn't live with I always ened up back on stock with mods. Haven't really tested any on the s2 but if I were to I would need to be very stable with very few bugs. I also kind of like some of the samsung stuff? for example I'm using a hack versions (fragg0rs) of TW4 with it I can run the buddies now widgit from the original galaxy s and I love that. nearest thing I can find to the carosel I used to get on the samsung omnia i8910 (great phone badly let down by symbian)
To the guy that criticised the length of the original post on top of what else that has already been said, do you have the first clue about troubleshooting? especially an issue that is not referenced anywhere else? The golden rule is the more information the better. This is an issue I have been working around now for several months, I have been searching for similar (on and off not obsessively) issues posted anywhere and found nothing that helps but thanks for your rather pointless input stick to helping with the noob posts eh?
This is known problem. I have this problem too.
Several threads already talked about this since long time ago.
Here are some of threads exactly describing same problem with OP:
http://forum.xda-developers.com/showthread.php?t=1285844
http://forum.xda-developers.com/showthread.php?t=1102920
http://forum.xda-developers.com/showthread.php?t=1328191
http://forum.xda-developers.com/showthread.php?t=1446961
That last one is the thread I created last month and still active until now.
So here is the summary:
- This problem is side effect since ROM version 2.3.5.
- Version 2.3.4 and earlier does not have this problem.
- This problem still exists in ICS LPB leak
- It seems that Samsung does not know about this problem.
The only workaround solution:
- Downgrade to version 2.3.4 or below
For us who have this problem, please add your post to the thread I created above (http://forum.xda-developers.com/showthread.php?t=1446961) and rate high to keep the thread alive so it will get attention from many users and hopefully from Samsung.
you just saved me money buying a new card thanks for that.

Hi all,
Im not a noob around here I have been lurking for a few years since I had my HTC hero and have been flashing my S2 for about 5 months now, very impressed with the amount of development here ...
I understand most things about flashing etc but am still unclear and have found it hard to find answers for the following:
I have Resurrection Remix 2.2 + siyah 3.3.2 + dualbooted with omega v15 4.0.3
1. Am I better off changing CPU frequencies/governers/voltages with the built in "performance" on Ressurection Remix or using the Siyah eXTweaks app
2. If I apply some settings in the extweaks app, such as an undervolt/BLN... will these settings apply to my second rom? + also, If I change settings on main rom, then load second rom, then go back to main rom will the settings still be changed on the main rom or do they get wiped.
3. I have one of those stupid small mini bluetooth keyboards which are about the same size as the phone and are under £10 on ebay... I also have a bluetooth mouse.. The bluetooth mouse works fine and stays connected for as long as I want, however does anybody know why the connection to the keyboard constantly times out after a few minutes? Very frustrating as I bought it to use with MHL adapter and have trouble reconnecting after its lost connection... I bought it because it was cheap and I dont have a lot of money to spend on that kind of thing, but if anybody has any other cheap alternatives can you post link.
4. A lot of the time recently, my phone crashes when watching a vide with MX player or playing a game... it just hangs.. dont know why, ive had RR running stable for over a week now with no tweaks applied and its still happening...
5. i have 4 copies of every folder showing up on memory card not enough space to copy data to laptop and format... any advice?
6. Advice needed on whats the best undervolt settings for me,I see multiple threads for Siyah _ extweaks but every time I mess about with that I end up breaking my rom and changing it... but when it has worked the battery life is great!
Apreciate anyone who helps or has any advice to offer, I will give thanks to you all.

1 make sure that they both are on the same settings.
2 I'm pretty sure it will only affect the rom you're on. Not both. Might want to check the dual boot thread though
3 try to forget the device and reconnect it/reboot then try to reconnect it
4 did you do a full wipe when you installed it?
5 I'm pretty sure there is a fix in rr FAQ on the op
6 not every device can handle being oc / uv.. If you break the rom on the setting increase it by 25/50 until you get it stable
Hope I could help

well the only little more advice given may be never under volt or over clock ur beast (GS2) since it never likes the same, they r only done on some specfic issues so keep the default settings
also the duplicate file issues its no more with 2.2 if u fallowed the extended installation steps in the FAQ properly

Do you mean it never works the same? I see, it's never been stable for me... however the extra battery life vs. risk of having to reinstall rom is a hard choice.. maybe if keep even more regular backups it may help if things go wrong..
And I have reinstalled 2.2 properly following the extended which I always do. Still have 4 copies of every file folder, and it's showing up the same in windows as well now. But i dont think it's taking up 4x the space...
Is there an easy way to fix this or am I going to have to reformat memorycard? is that best done on the phone or on windows?

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

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.
Has anyone tried either of these on our phone? I somewhat understand how fstrim works, but a bit confused on whether Forever Gone does the same thing (people claim to get the same results). I tried Forever Gone first and feel like my device has been zippier since, but I'm not sure, could be placebo. I ran LagFix the day after, so can't say either way.
http://forum.xda-developers.com/showthread.php?t=2104326
https://play.google.com/store/apps/details?id=com.kovit.p.forevergone&hl=en
I thought I'd post this for discussion, experiences, etc.
Right now I'm running seeder and lagfix, using both together with 1.72 overclock my device has never been smoother (battery life is better since i'm underclocked as well). Both might be overkill especially since our newer version of android should be cleared of the problems. But it seems to make an impact on my device. As for forever gone, it seems like all it does it clean up your sd card (internal and external? not sure if it does both, will try later) but that probably wouldn't affect the actual speed of the device unless you accessing videos, pictures, cached files from the sd (game files i.e.). Lagfix seems to be specifically for the phone main used partitions (system, data, etc.)
But I'm always willing to try out new things =D
Thanks for the post.
My phone has been a bit flaky lately. Recently upgraded to CM 10.2, Because I lost everything before, I really don't have many apps installed, but my phone now constantly says I'm out of space. When I use DiskUsage to look at it, it shows 572 Mb in applications 1344 in System data (leaving me with barely anything). I've moved most of the apps that I can over, so I'm wondering what other troubleshooting options I have to figure out what is using my space. I'm planning on upgrading to another phone before long but was hoping to make this one last another month or two. Just odd since prior to this I had it loaded up with apps and never ran into this. is CM10.2 that much bigger than 9 and that is causing my problem?
So in case anyone was interested. I found out my problem (found out others having issues on a CM forum). My \data\log directory had several hundred megs of logs in it. Once cleared, I had nearly 500 megs free. Just something to keep an eye out for. I know it won't permanently fix whatever the issue is, but at least my phone is up and working again.
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

Does this include doing a clean install? I mean doing clean install also slows the system? I've done clean install (re-install the stock Sony Z2 ROM) for 3 times till now. (Via Sony PC Companion)

included:
repair via sony pc companion
firmware upgrade
flashing custom rom
flashing ftf via flashtool
flashing via emma
all of those wear bout the same, its a matter of which one you do the most
in this case, flashing custom roms is this one

But I've done clean install via Sony PC Companion for 3 times now... So does this mean my phone isn't as fast as the day I bought it? Even though I've installed a clean ROM?

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
some info

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:

I've flashed previous android devices ( HTC magic / Desire HD / SGS 3) 100+ times each with no obvious slow down, my albeit limited understanding was that NAND chips where rated for 100k+ P/E cycles?

Correct from the wiki link provided a few posts ago:
"Most commercially available flash products are guaranteed to withstand around 100,000 P/E cycles before the wear begins to deteriorate the integrity of the storage.[21] Micron Technology and Sun Microsystems announced an SLC NAND flash memory chip rated for 1,000,000 P/E cycles on 17 December 2008"
