Volume Style not applying when pressing the volume up button on S25

[Neon]

I recently downloaded an app to change the look of the volume panel. For some reason, when I press the volume down button, it's the style I applied. But when I press the volume up button, it shows the Samsung panel style. Does anyone know a solution?

What app are you using?

Sound Assistant is the official method for customizing the volume panel.

If you are using a different app, it cannot be guaranteed to work properly or consistently.

An app called volume styles. I've been using it for years with no problem. But then it started happening after the recent software update 😕

The app likely needs to be updated for compatibility with Android 16.

You will need to contact the app's developer to report the error and have the issue corrected. If there is no error reporting mechanism within the app itself, you can find the developer's contact info in the Play Store listing.
