The cache partition probably increased somewhat, maybe some apps were updated. Try deleting it. Check in the file manager to see what is taking up all the space. 2GB of free space is not really enough for updates to happen. It is important also to note that wiping the cache partition does not clear the cache on individual apps. Try going to the storage settings of the big cache users, such as social media, email, web browsers and google apps and clearing the cache of each app.
It did it again.. the other night it took all my free space. I did a reboot and got apx 600 mb . But that didn't get it back..I cleared a couple cashes, deleted system cache. I'm still up to only 1 gb
Is there any way to get this back and prevent these system functions?.(updating or whatever)
It's a peculiar phenomenon on computing devices that the closer you are to your maximum storage limit, the faster the free space fills up. The free space on your device is used as a swap file for apps to work, updates and backups to happen. It's not always a matter of cache filling up. The free space will fill and empty depending on what processes are going on at any given time. If you are that close to your storage maximum, you might want to consider removing some apps that you rarely or no longer use, moving your photos and/or music onto a flash drive or other external device and clearing out any downloaded documents you no longer need by deleting or moving them to a flash drive. Don't forget to empty your trash.
