Android Memory Problem So I had a problem with my memory today. I recently rooted my Samsung Galaxy Trend (GT-S7392) with RootGenius 1.8.7 I rooted my phone because I wanted to transfer apps to my ext sd card since Samsung Galaxy didn't support transferring apps to ext sd. 

After rooting my phone, everything was fine, except I found out that my internal memory is full, so I checked it what was wrong with it and I saw that my system memory is taking all my space on internal memory. I dont really know what was the cause of it and my question is how to fix this? 

-Total Space: 4.00 GB

-System Memory: 4.00 GB

-Applications: 210 MB

Sorry for my grammar, english is not my first language :)

Thank you in advance!
The best solution would be format your mobile. There can be too much waste data in system memory.Or clean the system by using some cleaning app. There can be any number of reason behind this. BTW I would say that your mobile is outdated. In android, 512 ram and 4gb memory is not gonna do anything. It is gonna create problem again and again.
