Prior to Android Oreo I could see Memory usage by going to Settings > Memory but this does not exist any more since upgrading to Android O. Is there any way to see this now or has it been removed completely?

Enable Developer Mode (see here), and go to System > Developer options > Memory

Since accepted answer is not applicable in my situation (there is no "Memory" menu item) (Android 8.0.0, Samsung S8), I want to share another way of getting memory usage info. This shows RAM status and RAM usage by applications.

Settings > Developer Options > Running Services

This answer will only apply when you are a developer, and you have your development PC near.

First make sure that you have USB debugging enabled.

Then on your PC open a shell that can run adb (of you don't know what this is, then this answer is not for you)

Then in that shell run adb shell

This will open a shell to your Android device, within this shell you are running command line applications on your android device.

Now in this adb shell run top -s rss | head -n 20. This will print out a list of about 20 apps sorted by RAM usage(-ish, its not precise).

If you are able to enable ADB Root in developer options (Again, if you don't know that this is, then it is not for you), then you can see more details:

In the adb shell run su. This will elevate your access to the kernel.

Then run procrank. This will show a lot more info about ram and swap usage.


To show memory usage in android Oreo, first of all make sure enable developer mode in android Oreo

Enable developer mode android Oreo:

Settings > System > About phone > Tap build number 7 times

Now enabled developer options in android 8.0 Oreo.

Go to settings > System > Developer options > Memory > Memory used by apps

    Doesn't add anything new compared to @bmdixon 's answer.
