Hi all. well i have just deleted around 18 mbs with root explorer some apks on system/app , but It didn't free internal memory at all (it's still at 94.1 mb) I just did a wipe of dalvik cache (thinking that maybe that could work) but it only left 2mb extra free memory. So , what's happening? how can I permanently delete those 18mbs?

/system partition has nothing to do with /data partition where apps go ( /data/app ). deleting apps from /system ain't that bad - less crap in rom, basically but that's about it. theoretically u could move some apps from /data/app to /system/app but it goes with some security etc. implications. did it with few apps, worked, but rather for other reasons than freeing up /data (never ran out of space on S ). but as mentioned - it is possible, but not exactly so advisable. your phone, your choice

Hi, thanks for the answer =)
Ok, now I get it! So it's just to have less crap, couse it's the "system storage" not "application storage". I confused them. Thanks !!

Hi there
as I asked, I really want to know how these things actually work.
From my understanding, even though we have App2SD, the internal memory is still decreased everytime we install new app because it will generate the cache for that application (I tried install 5mb app, and what i get is i lost around 1mb of internal memory) is what I understand correct??
Now I currently have 150+ app installed in my phone with App2SD and I have 27mb internal memory left. If I move the dalvik-cache, my internal memory will boost up to 98mb. And if I install more apps, the internal memory won't be decreased anymore. but should I move the dalvik-cache?
According to some thread, it said that we shouldn't move dalvik-cache since it will make phone slower. But in my case I only have 27mb left in my internal memory so I can only install around 30 more apps. What do you suggest in this case?
Thx so much
PS. I attach the photo, pls have a look, why there are so much memory used in Data? thx
moving /data/data to sd would better than dalvik cache

Thank you, I did it but still... when I install apps, my internal memory is deceased Because dalvik-cache still affects my internal memory right? But I think I lost less internal memory compare to before(without moving /data/data to sd)
Is this mean I have limited of app installation even though I have app2sd?
thx
yes,

you may take at look at DalvikVM so you would know what does dalvik-cache do actually.
Rather than moving /data/data,
you may try to delete market, google map, browser cache and make a symlink to sdcard as well

Where is the cache located for market and browser? What folder/files do you actually symlink to sd card and how do you do it?

yeah, I would like to know how as well haha
Can you teach us how to delete market, google map, browser cache and make a symlink to sdcard?

i would like to know too.. please do tell
I've been having problems with the internal memory on my hero getting very low, and my phone seems to be slowing down a lot as a result.
I have apps2sd set up, and that seems to be working fine, however looking through the folders on my phone, the /system/xbin one seems very very large (582,031,812 bytes according to Astro).
What is this folder, and is there anything I can do to free up space? Would deleting the contents be a good idea?
if i'm not totally wrong that would be around 580mb, which just can't be true. besides that the internal memory is in /data, while /system/xbin is in /system, so totally different partitions (it is like asking "my space on d:\ is getting low, should i delete c:\xyz?"). last but not least you will most certainly break your system if you delete stuff from there. and the contents of everything inside /system ususally doesn't change, except you do it manually or use any kind of update.zip (new rom, theme, etc).
try wiping dalvik-cache from recovery, that might free a few mb.
Thanks.
I thought it didn't make any sense, and that it must be in a different place to the internal memory. Ok, I'll look through data to work out if anything is taking up more space than expected.
What will I lose by wiping dalvik-cache?
Why would my memory keep on shrinking? My apps are on my sd card, so it shouldn't be them...

nothing, it is recreated on boot. the problem is that when you uninstall an app the optimized "copy" of the app is not deleted from dalvik-cache.

for once through dalvik-cache, everytime you install an app it takes some space in dalvik-cache, though not as much as the app itself. besides that the app data (settings, savegames etc) is stored in /data, as well as system settings.
Hmm, deleting the dalvik-cache didn't make any difference.
So, I'm a bit stumped as what to do here. I have an LG Optimus V, running on Virgin's network. I have rooted my phone through IHO (using CM7.1). The guide I used to root the phone I would link but since I'm a newbie I can't...
My problem is the system cache is slowly diminishing. I've noticed this when I try to go and install an app on the market and it says I have insufficient space on the device. Well, I have around 100mb free on the phone, and around 7gb free on my SD card. So, after some research I found how the market install apps through the cache.
Every post and guide I've read to fix this issue says to wipe the market cache and data, or wipe the phone's cache and dalvik cache. I have done both. Still, I have insufficient space on the device. I got a system stat app that displays info about the cache. For system cache, it says I have around 110mb total, but only about 12mb free.
So, I recovered a backup of mine (it still had IHO running). This time it had 20mb free, even after wiping all the cache. I tried wiping the cache through Titanium Backup, with no luck.
At this point, I'm unsure how long I've had this problem. I wonder if I had it from when I first flashed IHO (which was sometime early January) and the cache has just slowly decreased over time, and it's gotten so low I'm now having issues. I didn't have this before I rooted my phone. But this is obviously a problem, because if it continuous to decrease, not only will I not be able to install hardly any apps, but I won't even be able to download updates, to my understanding.
So, after that backup failing I went on to flash my other backup, rooted but without cm7 flashed. However, before I tried recovering this backup I wiped the entire phone (data, cache, dalvik cache). Then after trying to restore I got a MD5 mismatch! error.
I've scoured the internet and can't find anything relating to my cache issue. I feel helpless! And I have no idea what to do. Any ideas?
EDIT: I don't know if this matters or not, but I forgot to mention that the recovery I'm using is called "Xionia CWMA" v1.2518.6. I'm assuming this is a modded version of ClockworkMod.
I think you are getting the system and data partitions mixed up.
When you install apps from the market, they take up space in the /data folder in your phone. I believe this folder can also be looked at as your internal memory.
The system folder is a whole other folder that the market does not touch at all. The apps in the /system folder are your system apps (pretty much all the apps that cannot be uninstalled through settings).
When the market says you have insufficient space on your device, it is saying that you need to free up some room in your /data folder, not your /system folder. One thing you can do is start moving all of your apps to the sdcard. There are two ways:
1. Go to settings>applications>manage applications. Under each app, select the option "move to sdcard."
or
2. Using titanium backup, you can do a batch operation that automatically moves your apps to the sdcard for you (menu button>batch>move user apps to the sdcard).
This should free up a lot of space if you haven't done this already.
As for your md5 error, I have no clue about that.
Hmmm. OK. Well I have most of my apps moved over to my SD card. I would barely have much space to do anything if I didn't move them to the SD; this phone has a pathetic internal space.
I'm looking at the app list and it says I have 72mb used, but 107mb free. I'm pretty sure that this is enough space to install an app at 20mb! As for my SD card, I've used 7.06gb and have 7.9gb free.
Thing is, before I rooted I didn't have the insufficient space error, and I had WAAAAY less space free. I would have around 40mb free maximum. Even when I first rooted the phone and put cm7 on it, this problem didn't appear. It started popping up maybe two weeks ago or so? And it seems to be getting worse.
EDIT: Ok, so I went and tried using Titanium Backup to move the rest of my apps to the SD card. I moved everything except my theme (LunarUI) and LauncherPro. I think I read somewhere you shouldn't move those apps. Anyways, I now have around 130mb free of internal space. And I still have the insufficient space error.
Need some help. I have a Dell Venue with 2.2. I have rooted the phone and installed ClockworkMod so I can get to the root directory. I frequently get low memory warnings and even warnings that an SMS message was rejected due to low system memory!
I have moved all of my downloaded Apps to the SD card (and deleted quite a few). I have set my email app to store email on the SD card. I have gone through the root directory and removed system apps that I do not ever use. I have even cleared the cache and the dalvik cache. All of this has helped, but only briefly. After doing all of this, the phone will be ok for maybe a day or two, then the warning returns. When I 1st got the phone a year ago, I had no problem having tons of apps stored on the phone, now I can't hardly have anything.
The warnings start at about 53M of internal storage available. Is there any way to free up more internal storage? Are there unnecessary files that can be deleted?
I really liked this phone when I 1st got it, but now I absolutely hate it and I am stuck with it for another 6months! HELP Please!
/cache and /system are seperate partitions: cleaning them won't give you any more space on /data.
you could move some apps into system if you understand some of the risks:
You have to manually update the copy in /system or you will end up with an old copy in /system and the new one in /data
modifying /system can lead to bricks if you don't understand what you're doing
Thanks!

Thanks for the info. Unfortunately, something else has happened and my phone may actually be bricked for some reason. I decide to just factory reset the phone and reload everything from scratch hoping this would clear up the problems. As it goes through the start up, I connect to WiFi, connect to my google account, and when it attempts to start the Dell Stage, it just locks up. I have factory reset it 3 or 4 times with the same results every time. Not sure what happened.
Going to search on here to find a fresh copy of the factory ROM or maybe someone has posted a Nand backup that I can load from the SD card. Any suggestions would be much appreciated!
Hello!
Few months ago, I rooted my Sony Xperia ZR (C5502) official ROM build 10.7.A.0.222, android version 5.1.1. Yesterday I decided to uninstall all the bloat that came with my device (like Google Play Movies & TV, Google Play Books, Hangouts, etc). I used Titanium Backup to uninstall these system apps. After that, I got lot of free space in my /system partition (around 500 MiB). I wanted to make use of this space by moving some apps installed in phone's internal memory to this /system partition. I used Link2SD's Convert to System App so that these apps move from /data partition to /system partition (I made sure the apps I moved were really installed in phone, and not external SD card's asec).
Now what should have happened is, /system partition should fill up, and memory in /data partition should free up. However, what happened is, /system partition filled, but no memory was freed up /data partition!! I suspected if Convert To System App just made a symbolic link in /system partition, but this wasn't the case. The /data/app/<package> folders for all apps I moved, were gone. I also executed ls -l on /system/priv-app/<package>, but it didn't show up as symbolic link.
I want to know why is the space in /data partition not freeing up? Thanks!
PS: I've also used Link2SD's Integrate update into system function, for those system apps that have been updated. That did free up memory in my /data partition.
Solved
I found the problem. Couldn't find a way to delete this thread so I'll just reply what I found.
Converting user app to system app only moves their apk and lib to /system. app's data and dex still reside in /data partition only, hence the space didn't free as much as I expected. However, I cleared dalvik-cache and then when they were rebuilt/recompiled on next phone restart, I could see a lot more free space in /data partition. This shouldn't happen though since Link2SD delete the old when when I converted and new one was made on phone restart. Maybe it couldn't delete some.
