Help RAM issue

[PRkid]

So for a couple of months my ram has been showing 0mb free. Whether I turn off and on my device or Uninstall apps, the amount of RAM never goes up. It stays at 0mb free. I have the 2gb version, but I still feel like it should be higher than 0. Any idea on why this is happening? On Memory under settings, it shows Performance = Normal. Total Memory= 1.8. Average Used = 7%. Free = 0b

This maybe a simple reporting glitch... If you really had 0 ram available the device would grind to a halt and be nearly unusable.

Try installing a terminal emulator application and open it and enter the command "free" and press enter and capture the output (a screen shot is fine, preferably in landscape mode). It should look something like this:

Thanks for the tip. This is what I got

Your "free" memory is about 90MB... not zero.

The second number on the line that starts with "-/+ buffers/cache:" is the amount of free physical memory you have on the system in kilobytes. This number is also ram that isn't being used for disk caching by the kernel. The 3rd number on the line saying 'Mem:' is the amount of physical memory that hasn't been allocated by the kernel for any reason.

This is normal (look at mine, I have the 4GB RAM version and have ~130MB free)... if you are not experiencing any performance issues I wouldn't worry about it, it is a simple reporting glitch in the settings menu Memory "app". You can't think of an Android device like Windows, you shouldn't have very much free memory... "free memory is wasted memory" as apps are cached into memory for quick retrieval later, the kernel manages this quite well in most cases.

@scary alien provides us with a 'Ram Truth' app that has a really nice GUI for all-things-RAM:

... or if you prefer a terminal, using
free -m
might be a little more palatable.
