I'm using LG L3 E405, and when I see memory usage in App Manager. I see there three sections: First is system memory (just about 200M), second is internal memory (1 GB) and last is my sd card (8GB).

I know difference between internal memory (is internal sd card) and normal sd card. But I don't know purpose of system memory. It's too low, and often applications are installed to there. After install, I must move those apps again to internal memory, but not all I can do this.

Please help me figure out this point.

  • Internal memory is the actual RAM "chip" (for want of better word, technically integrated within the CPU) itself. System "memory" is a partition in which the Android OS resides in (note how I emphasized memory in context of system!)

    Isn't system memory a memory where Android OS is installed? Internal memory is where the apps are installed (or necessary files are linked). SD card gets the secondary storage.

You better go to Cellshopes, get "Root" on your Adroid device, but it's too risky and oftentimes warranty will be voided once it happen.
