[Q] How much space does the OS take up? - Nexus 7 (2013) Q&A

Quick random question, but how much space would you say does Android 4.3 take up on this? I calculated about 3.2 GB. Is that right?

These are reserved sizes (MB is base 2, ie MiB), unless otherwise noted
Bootloader(s) 12MB
Kernel 16MB
Recovery 10MB
System 827MB (591MB used for JSS15J)
Cache 551MB
1416MB total reserved.

Those are the partition sizes (except for the /system usage # which is the actual Android OS size)
I didn't include /data because that gets populated upon initial install with user data. While there are some technically OS files stored there, most of /data is going to be related to apps and data created after you start using the phone.

Maximum App Storage Space

Does anyone know if there is a maximum app storage space allowed? got a strange message on download from the market when it fails saying there is insufficent space, when there is 9.1gb of space in the phone still. possible partition?

I think on the GNex the whole SD card can be used for installing apps. Google did this on purpose to cope with the "Not enough free space to install" issues one had on other handsets.
Are you on Stock ROM?
Stock Rom, I thought that was the case as well, I think I may have found the problem might be to do with restricting background data? will test and see.
Go to Settings -> Apps -> Market -> Clear Data. Try again. It's a bug likely.
There was an "out of memory" issue on Honeycomb tablets which required a device wipe to correct. I hope you get this resolved. I'd hate for this bug to be in ICS.

a2sd/data2sd priority method

I understand that NAND is more rapid than sd card and differences between a2sd method, like the picture report in Amarullz thread.
I wonder if exist a method to give priority to some apps rather than others in internal storage.
I mean: for example, suppose that I have 50 apps but I frequently use 10, might be more performant put 3rd part App data and APK (and dalvik if is possible to separate it) of theese 10 apps in NAND and other datas of the other ones in SD card?
Maybe this requires also a GUI to choose apps, I can't imagine what it takes this. Sorry, maybe this idea is absurd, I don't know about programming, it's just.. an idea.

Does link2sd do that? Not sure..
https://market.android.com/details?...?t=W251bGwsMSwxLDEsImNvbS5idWFrLkxpbmsyU0QiXQ..
Think so..
Im not sure what Amarulz is stating system apk's are in those pictures, but to me they are always on NAND, so those pictures are probably specific to one of those sense roms for cm7 that have to export system app to ext to fit....
Thanks, I didn't know about this. I will try it and post my impression.

[Q] "System data" folder taking up 10 GB, what's causing this?

Pretty straightforward, why is a third of my storage being eaten up by "System"?

In the clockworkmod folder on my phone? I've emptied that as well.
Google play; search "disk usage"
Edit: Somehow I actually missed the image on the first post. That's disk usage. Glad you figured it out, BTW.
a maguro sent this.
I figured it out. In Clockworkmod under backup and restore there's an option that says something like cleanup unused data. Selecting that seems to have fixed it.

Tombstones are dump files from crashed processes. If you are not debugging and don't need them for troubleshooting (IE you are not in contact with the developer of the crashed app) you can delete them if you have root access. Of course they will probably be recreated as the app crashes again, but if they belong to an app you have uninstalled ( or the app has been patched and no longer crashes) you will regain the space "permanently".
Thank you. That is very helpful. I have no use for them and will delete them.
Is the same true for the contents of /data/system /Dropbox?
Can I delete these too?
Finally, are these app usage stats also deletable?
I'm doing some housecleaning.....
The dropbox files look like crash dumps and troubleshooting stuff, you might want to google it to be sure. As far as the usage stats I suppose if you wanted to you could delete them it *should* just zero out your stats. I would try moving them first to see if it causes anything crazy to happen.

OS Occupied space too high. Please help! :'(

As you can see my OS Occupied size is very very big (8.13gb) . It's not a ROM related problem as i've tried many ROMs and but the size remains same.
What i believe is the reason is my fked up partitions. (ext4 + fat = both combined = 8gigs).
Any way to fix this? Any way to restore my old P2 like literally everything including partitions and there size etc.?
Where could i locate these 8gigs of files? :silly:

That is the standard partition for the OS, no changes possible or needed.

OMG i didn't knew that i always thought it was 4gigs or something, but why this much? like is it really required? 8gigs is too big imo.

32GB are real ~29,8GB which you can use. On your picture you have ~24GB free space. So 29,8GB - (~) 24GB = 5,8GB
Can you follow..?
Thats normal on android devices except you want to complain about ±500mb or something like that.
