[Q] S3 using 20GB of System Memory! What is going on?

I have a 32GB S3 with only 5.73GB of available space. Looking in my storage settings the reason is System Memory is gigantic at 19.95GB.

How can system memory take up so much space? I mean most S3 phones are only 16GB total.

Something is obviously amiss but not sure how to get to the bottom of this. Any help or suggestions would be appreciated.

TIA

That's definitely not right, if I was in that situation I would try to make a backup in recovery (if system is actually 20GB I doubt you'll have enough space) and then I would wipe everything (system, data, cache, and dalvik) thoroughly in recovery and reinstall the ROM to see if this issue persists.

If you go to Storage, in settings, and tap on the various categories shown there (Used Space, Miscellaneous files) you can dig down and maybe see what is taking up so much space. Give the phone a minute or so to calculate the space each time you go to a new page.

I am fully stock so I can't make a backup in stock recovery. And I am stock ROM so there is nothing to reinstall.

That's what I did, that is how I know the System Memory is taking 20GB. That is where I can see that. Clicking on the System Memory category does not give you any further breakdown.

See the attachment.

You might want to try an app like SD Maid. It has an option to find large files, and it can clean up all the cruft that collects over time.

I'll give it a go but this phone isn't even two weeks old.

I'm totally baffled here.

That was quick and easy. I just ran it and there are no egregious offenders, as I expected.

This 20GB of system memory usage on a new & stock phone is ridiculous...
