How to resolve issues that may arise after changing Developer options on your Samsung Galaxy device

Developer options on your Samsung Galaxy device is a hidden menu intended for application development and testing. It contains advanced settings designed to assist developers in testing software and improving overall system functionality. Modifying settings in Developer options without fully understanding their function may cause unexpected issues, including display changes, reduced performance and functionality, app crashes, and increased battery consumption. If you experience performance issues after making changes in Developer options, follow the optimisation steps below to restore default settings and turn off Developer options.

Developer options features can significantly affect system functions and app behaviour. Modifying settings without knowing their specific purpose may lead to the following symptoms:

• Window animation scale changes: Screen transitions or app launching speeds may become unusually fast, slow, or choppy.


• Background process limit changes: Apps running in the background may be forced to close during multitasking, or push notifications (such as messaging apps) may be delayed.


• Strict mode enabled: The screen border may flash red while apps are running.


• Minimum width modification: Some apps may close unexpectedly, or display errors may occur on the Cover Screen (for foldable devices).

You can access Developer options only after they have been enabled manually.

If you encounter performance issues after modifying Developer options, revert the changes to their original values and toggle off the menu.
