Hi there.

I seem to have Lost about 8 gig of memory, and I've no idea how to free some more up.
Settings->storage shows....

Total space: 13gig.
Apps: 300 Meg.
Pics +music +etc : 10 Meg.
Free: 4gig.

I have the 16 gig model, I realise that is 16 gig of unformatted space, and the filesystem will eat a chunk, but 3 gig seems a little excessive.

And what about the rest of it? I've not stores any media on the device, and I've only installed one up ( world of too - 50meg )

I was hoping to store some media on the device for a long offline journey.

Any ideas ?

Are you sure you got the 16GB model and not the 8GB by mistake? Are you rooted? If so, use a root file manager to look at the file systems/mount points.

Thanks for the reply root brain.

This device is not yet rooted.
Surely is I had the 8 gig model then free space would be < gig... unless there is some compression at the filesystem layer ( but I don't think ext4 supports compression)

I do have a terminal emulator installed, cat /proc/partitions shows /dev/Mmcblk0 to be 15267840 blocks. If that's 512 byte blocks, then that's only around 8 gig. I'm hoping they are 1k blocks... I'd rather not root the device, just in case I need to return it.

Could anyone with a 16 gig model post the output from mount and cat /process/partitions please ?

Thanks.

You're right I didn't pay attention to the settings/storage comment you made, sorry.

I also show 13.24GB total, so you have the 16GB. I'm using 2GB for apps, 2GB for audio, 833mb for pics/vids and have 5.8GB left. However, using a custom kernal and init.d for some custom tweaks which include a 1GB swap partion (equal to memory) for performance.

Curious, unless you got bad memory and it's not recognized.

:thinking::thinking: If you feel like starting over, try doing factory reset and starting from scratch to see if it builds everything and you can recover it. Or look for some disk tools in the market, but I think you'd need root to get to the nitty gritty. Don't know what else to try.

I have exactly the same problem. I had the full 13.24gb and had transfered some movies onto the device nearly filling the memory using nexus media importer. I then deleted them after watching and never got the memory back. I am actually using 5.32gb but the system says I have used 11.71 GB out of 13.24Gb. Any solutions apart from a factory reset?

You could probably use a file manager to see where the space is being used. Then remove any files, have did you check the storage usage bit to see what the used space falls under? Also, I was under the impression (someone told me) that Android was suppose to be installed in a seperate NAND Flash to retain the space? This true?

Here's something I found using these tools. I had the app "Root Uninstaller" and it had over 850MB of "automatic backups". WTF? Why does that app do any backups anyway? I use Titanium and Nandroid so I don't need apps doing anthing "automatically" without my say so.

Thanks to the suggestion for the above disk apps, I saved almost a gig or storage. I use the No Bloat app exclusively now to remove system and user apps that I can't get rid of any other way.
