So first, when I go to Settings -> Apps this is what is shown:
After some time ~20 seconds, the amount of space left is this:
Why does this happen? What does this mean? And when installing any Android app I always get the insufficient storage space error. Why?When determining the amount of space that is free, which of the two screenshots' storage space does the Android OS consider? Anyhow, in both the cases the minimum that I had was 40MB and the app that I wanted to install was 12MB, yet I got the error. I am running on HTC Legend, Android 4.1 Please clear this confusion. Thanks!
