Do not write on flash by any UI movemend.

The application would like to write on flash e.g. while rotating screen, while leaving "Settings" without changing anything, while leaving "About", while entering the App and many other situations. Its not really a bug but its not a good way for flash lifetime.

How did you check this? I removed one save action after the settings screen was rotated, but don't see any flash writes (in the code) for the main screen when returning from the about screen.

I configured the Andriod Privacy Guard to notify me about all access. So if I rotate the screen the Privacy Guard is asking for flash write access.
