So, it is as the title says: my Samsung Galaxy J5 (2016) is filled up. Not with apps, but with "System Memory". The device only has 8 GB of storage, and about ~48%+ of that (3.3 GB) is used by System Memory. Well, apps fill 4 GB, but that is why I have removed about 20% of the system apps (like Google, Hangouts, and many more).

What do I do? How do I get rid of extreme amounts of space used?

  • Even if there were tons of "system memory" free: there's nothing you could do with it. System storage is reserved for the system (oh, and for pre-installed undeletable bloat, of course) – and mounted read-only. So to install apps and have them store their data, that area isn't available anyhow. – Izzy Oct 28 '17 at 20:05

The "system memory" Is where the Android OS is installed so there is no possibility to delete that


Just to be clear, you can't get rid of system memory but you can disable some apps that comes with the phone. I've answered something like this Here on how to free up space on your device

Cheers :)


I have a Samsung s9 plus and the app that was taking up all my storage was My files (ironically). I went to settings/apps/My Files/Storage and the data was a whopping 6GB. I hit Clear Data and freed up the space. I'm not sure why a file browser would need to hold on to that much data, but it's working fine without it.


To clear the system memory, you would have to delete the app and then re-install it from the Google Play Store.

    Pardon, but without root powers, "system memory" cannot be dealt with. – Izzy Oct 28 '17 at 20:03
