System Memory fulls it self
Guys i really need your help ! i cant even read text messages
I updated(Odin) my galaxy to Jelly bean(H3G-I9100XWLSW) and the phone was working fine , i installed whatsapp , facebook and facebook messenger just those 3 and left my phone there the next morning it had a notification of that said that the system memory was low , that i had to delete some apps and yes the apps memory was full it only had 20 mb free it filled by it self! i did a wipe and again it was fine memory was normal and then it filled it self again
installed a custom rom (NeatRom) and it happened again, i think it might be the partition of the internal memory so what can i do?
should i flash it with a .pit file ? (where can i get the pit file ?)
i dont really know what to do and wipe every time i need to read a text message is not nice
