Before Android L update my mobile(Nexus 5) used to use around 1GB RAM.
Now, it's using around 1.6GB RAM leaving me only 250MB free memory. When I look into device memory, it's showing
System is using around 1GB RAM.
Is it normal for Android 5 to use 1GB for System and why is that? If not, what wrong with my device? I updated my device using factory image from android download page.
