For example, I have apps organized in folders according to function, but after a recent update one of my earthquake tracking apps took itself out of its chosen folder and deposited itself as the last app on my last home screen. I want my apps to stay where I placed them. Is there a way to prevent or to fix this?

I have seen similar things happen with some apps every now and then during an app update.

Fortunately they are very infrequent.

Unfortunately, the problem is probably in the app's APK file settings due to a mistake by the programmer. Thus there is nothing you can do.
