Developer Options: How to use the "Strict Mode" feature
NOTE: Developer options are for development and testing purposes. Changes may affect phone performance and stability. It is advised that you keep the default settings; otherwise, please proceed with caution.
This feature crashes apps if they perform long running operations on the processing thread used by the system to run the user interface. This allows developers to identify situations in which their app does this and remove them, so the user interface doesn't freeze when strict mode isn't on.
NOTE: When select “Strict mode” is enabled, a red frame will intermittently show on the screen while performing applications.
To use this feature, go to: Menu > Settings > Developer options and look for Strict mode.
