Hi...
I was thinking about my original problem (as seen below) and thought that the following might help to solve this problem:

1) Un-root my phone to the original system apps
2) Do a "Factory data reset"

Any suggestions?
-----------------------------------------------------------
ORIGINAL PROBLEM:

I am currently using a Samsung Galaxy GT-I8190 (S3 Mini) running Android Jelly Bean 4.1.2 and I rooted my phone in order to get more internal memory to my disposal. (FYI, i also have the Recovery-Clockwork-Touch-6.0.2.7 on my phone when I rooted it)

It worked, but only for a little while. Then the memory started getting full and pops up a "permanent" notification to say that the storage space is running low.

I have an app installed by the name of "Clean Master" and I frequently clean the "junk" files (cache & residual files) on and clean it at the advanced side too, so there isn't any unwanted apps or empty files laying around on my device. I also do a 'memory boost' to get an extra bit of RAM, but nothing helps to clear out the internal memory space.

I also cleared out my clipboard of everything I had copied and I un-rooted my phone to see if it would help, but the memory just got fuller again so then I rooted my phone once again to take away the unwanted apps.

I also have a 4GB external memory card in my device and I've moved all the apps (part of them that could move) to the memory card, but no positive results to my liking as yet. I have also kept all my music & pictures on my external memory card and I keep my download file, on the device, empty because I move everything onto the ext memory card.

What can I do to clear up the memory? Because I can't even update my current apps or download any other apps because of the lack of space.

My Gmail or Google Drive apps don't even want to refresh because of this storage problem.

Please help!
Thanks

 

@Rukbat - Thank you for your contribution, but here is what I think:

FIRSTLY, I am aware that rooting your phone installs a file and app, but it hardly takes any space at all and wouldn't make much of a difference if I took it off.

SECONDLY - I am also aware that when you save a picture it takes storage space, BUT I move everything to my EXTERNAL MEMORY CARD so that it does not take up space internally.

THIRDLY - It is obvious to me that when you install an app it takes storage space, it can't hang around in the air.

FOURTHLY - You said "Because you're using it up by using the phone", does that mean I must not use my phone at all?

FIFTHLY - I DELETED all my UNWANTED APPS and I had MANY more apps on my phone before and it DID NOT GET FULL. I only have like 27 downloaded apps on my phone. If you are telling me to delete EVERYTHING off my phone, what's the point of having the phone then?

SIXTH POINT - To answer my question that I stated in the beginning, would it help if I UNROOT my phone and then do a FACTORY DATA RESET on it?

 

IT WORKED! Thanks so much @Rukbat ... I understand now that rooting your phone gives you less memory. The factory reset helped me a lot now and I'm only using a fraction of the internal memory that I used before.
Everything is back to normal now
