Memory hogging

There is a mysterious app or process hogging the majority of my available memory. I have tried to investigate the culprit using Task Killer and the apps section in settings. Neither of these reveal it. The apps listed in Task Killer and Settings equal only about 100mb of memory usage, however, it shows over 600 mb being taken. My LG tablet has also been running very slow.

Does anyone have any ideas about what could be hogging the majority of my tablets memory?
 
Hi cliftonmarie, welcome to Android Forums :-)

This topic comes up quite often and while it's possible you have a rogue app or process it's far more likely that there's nothing wrong at all - the Android OS is designed to maximise the use of RAM, not freeing it until there's a need to do so.

This is quite unlike the behaviour of OS like Windows and can cause much confusion to new users; best practice is to let it do its own thing, and in particular the use of task killers can actually be counter-productive with modern Android versions.
 
If that's true, I wish it would keep more free memory available because my tablet runs super slow after using a few apps. It only keeps about 100mb available. I'm just curious what is actually using all that memory. Is there a way to find out some way besides the ways I've already tried?
 
I forgot to ask earlier - which Android version does it use? It shouldn't matter with any recent version but memory management on some older Android versions was... well, let's be kind and say "sub-optimal" :-(

Finally (for now!) where are you actually getting the "free RAM" figure from? I ask because it's not as clear-cut on Android as it is with some other operating systems; results from different sources can differ and sometimes be quite misleading.
 
I'd bet on it being Android 2.3 or 2.2. those two never were very keen on RAM management. that was changed in 4.x and up.
