Hi !
I've made a search but I've found nothing about that. Maybe I don't use the good term...
I'm currently trying to build a ROM for a tablet device (kyros mid 8127) but this model have a really limited system partition of 180mb. It's really small considering porting serious ROM or even just install gapps in system apps...
On the other hand, the app storage partition is far enough for me with its 700mb approximatly.
First, I though to change the mtd partitions. But this is to scary for me as there is no pre-made solution for this model and I don't want to brick my device ^^
So, I'm wondering if it's possible to store system apps on app partition instead of system partition ?
Don't know if this is really possible, but do you guys think I could extract the /system/app folder somewhere on internal app storage partition during ROM installation and symlink the /system/app folder to this place ?
data/app
Swyped on my blade
Yes, data/app is a solution for secondary apps. But I need to move all system apps to free space for framework etc... I've read that all system app can't be moved to data/app cause they'll not work properly from there.
So I'm wondering if we can trick the system just by symlinking system/app to an other location.
I've been using titaniumbackup to move apps to sd but my system partition is full now and theres nothing i can do.Will a script like Link2SD or others fix this?
No If you don't have an ext partition.
Backup all your apps (almost data) and make a new fresh install of the rom. Before flashing create an ext partition from recovery.
You can use link2sd or whatever script you want. I've always used link2sd because of its full control of installed apps (link/unlink/move to system, etc.) Now I'm very happy with int2extv2+.
But as anyting on android it's all about personal tries and choices.

As we have a very meagre system space, it becomes as much as a necessity to use different '2SD' scripts like Link2SD on the phone to enjoy our favourite apps..i use Link2SD and am very happy & satisfied with it..
I'm on a small rom, so I've have extra fee space on the system partition. I was considering moving some apps over to system. What happens when a new version comes out and I update the app, will it install on the system partition too?
UPDATE : I MANAGED TO FIX THE PROBLEMThe way is to clean format the system via twrp (switch to ext2 and switch to ext4) or something similar, the storage partition will restore to its original state
Hello everybody, recently I decided to check the storage allocation and saw that system is using a large portion of my storage space
Any suggestions ?
Maybe with root you can debloat some useless apps.

That's a bit strange.
I'm pretty sure, though, that stock apps aren't included here, maybe only core system apps. Because I have disabled a lot of pre-installed apps and the system storage space didn't change that much, only App storage. Mine is currently at 10.26GB, and I'm pretty sure it's been like that out of the box as well, maybe a bit less.
And my cache sits around 500MB.
Either way, go to your settings-apps and disable what you don't use. After that use some sort of a cleaning app, like Clean Master and run it. Just make sure you uninstall it after you're done.
If none of that helps, I'd do a complete format and clean flash via FlashTool, or use xperia companion to repair the software.
40GB for system storage seems a bit extreme. Maybe I'm just not that heavy user, but I don't see how the user can even affect the system storage, apart from cache. Even when updating OTA, I'm pretty sure those downloaded packages get deleted afterwards.
For most of the useless stock apps, you don't need root to disable them, it is not the same as completely removing them while rooted, but it will still free up some storage space and prevent them from running in the background.

Brother. I already did that. Nothing changes. The only way is root it and remove ( not only disable ) the apps using titanium backup ( or some program like that ). Don't forget to make a backup from them before remove the apps.
But, i think that this process don't result in alot free space. Maybe when android compile the apk in cache the result naturaly takes this space. I have a 64gb XZ and this issue really annoying me too. If i discovery something i share with you.
I'm trying different apps that claim they securely erase files and/or securely wipe free space on your phone. None seems to work on my phone so far with little exception from Secure Eraser (it sometimes results in unlisting erased photos in DiskDigger). I wonder if it is just with my phone (rooted). Does anyone had had the same problem and eventually succeeded?
I'm aware phone NAND memory is not SSD and does not have TRIM instructions, thus file shredding might be impossible to achieve but why free space wiping does not work, either? When saying an app does not work I mean the deleted files weighing 3MB each (JPEG pictures) are fully or partly recoverable using DiskDigger root scan of /data partition (the original pictures, not only their thumbnails hidden somewhere on /data partition). I tested each app's file shredding and free space wiping functionality only to find no alleged function works.
Apps I tried:

My phone's configuration:

Rooted (for apps and adb),
Internal storage fully encrypted (customized with third-party app),
/data partition is formatted using F2FS file system,
stock camera app (destination: Internal storage),
all erasers are granted storage permission,
DiskDigger is granted root access and performs root scan

Because deleted data is not actually deleted, it is only "marked" to be overwritten the next time the device needs to write/save data, in the meantime, the data is still "there", it's just being ignored by the system. The only way to really do what you're looking for is to actually format the whole partition(which wipes everything in that partition), you can't just format the "free" space at the "end" of the partition/drive.
Android doesn't work the same as PC, you seem to be trying to treat your android device the same as you would your PC. There is not that much similarity between them, they are pretty much their own different worlds.
But, you're in luck because there is this

It kinda does what you're looking for but in a different manner.

I get it but this is why Secure Eraser (brought by an xda dev Giuseppe Romano - https://labs.xda-developers.com/store/app/com.aiuspaktyn.secureeraser) works in a proper way writing dummy data to the partitions so all the free space on the physical internal card is being overwritten. It means Android gives you a warning you're running out of free space, stops the app and you have to click on the app again so it can proceed up to 100% of internal memory's free space. Still, it works only sometimes - the later you use it after deletion the smaller chance of success you get. I guess it's worth **** cause wiping is actually being done on /data's free space which doesn't mean you wipe all internal memory card's free space (let's call it a PC hard drive). There is still free space located on other physical partitions (Boot, Cache, Recovery, System, Vendor).
Fu*k it - I may have just answered myself. Where is an Android app for a rooted device doing wiping free space properly (wiping the whole internal card's free space), Anyone? A solution related to TWRP, adb command, perhaps? We need a decent [email protected] Kill Disk for Android, guys - nothing works at the moment.

The thing that makes it tough to have a good tool to do this on android is the way android is partitioned and how permissions and read/write works in android, along with certain proprietary motivated hardware/software blocks implemented by manufacturers and carriers.

Reviews on play store confirm that secure eraser isn't working. Disk digger still finds files. Don't trust it.

The app was bought by Mobile Safe Apps, they probably destroyed it. You can still get the apk from the xda dev Giuseppe Romano - https://labs.xda-developers.com/store/app/com.aiuspaktyn.secureeraser. Thanks DonKichot.
