Applications Crashing....MAX RAM?!

[SWD]

Earlier today my phone was acting buggy. Typically my phone would use 200mb of RAM average. Lately my wallpaper would dump, chrome would crash while searching on google, twice my phone crashed while on a phone conversation. I looked at my ram was at 790mb/812mb. Yeah I have a Samsung Galaxy Express.

In the task manager I had cleared the memory and restarted the phone. I am constantly at 600mb+ of RAM and after 5 minutes of use it would max.

Only apps I really have that I sorta use is facebook, youtube, and a 1.8mb game.

I have been reading that 400mb is average for a phone when clearing the memory. What happened?!

Currently have android 4.1.2

The way Android works, it will always want to fill up free RAM with processes so that they're more quickly accessible when you need them. In general, RAM will optimally be used at around 70-80%. I'm not a total Android techie, so I can't give you the down and dirty details, but in short, when the system detects that it's crossed a certain threshold of RAM usage, it will start shutting down less recently used processes to free up more RAM. 400 MB out of 812 MB RAM used is pretty low, and would not be how things are supposed to work. However, 790 MB out of 812 MB RAM used is pretty high, so that could explain why your phone's been acting a little loopy.

If things keep bogging down even after a restart, I would suspect one of your apps misbehaving. When your memory usage is up around 790 MB, take a screenshot of your Running Apps screen under Settings/Apps/Running, so we can see which one the hog is.
