I've noticed over time when either installing or updating an application memory seems to randomly decrease like there is some hidden cache. Is there a way to wipe that said cache? Would I have to reboot the phone and upon start up hold the volume up and down and clear data cache? Cause I don't want to have to factory reset just to get that extra memory back. To me its extremely annoying lol and oh yeah, even after a while, while its on idle, my phones internal memory decreases just a little bit just from being idle! I know none of my apps are automatically updating because I manually do that myself.
