• App Version: Latest release

Description

Network mode switching is not working on Samsung Galaxy S25 Ultra running One UI 8.5. When attempting to toggle between configured network modes using Shizuku permissions, the network mode fails to change and remains stuck in its current state.

Steps to Reproduce

1. Install and open NetworkSwitch on a Samsung Galaxy S25 Ultra running One UI 8.5.
2. Ensure Shizuku service is active and permissions are granted to NetworkSwitch.
3. Configure toggle modes (e.g., Mode A: LTE Only, Mode B: NR/LTE).
4. Tap the toggle inside the app or use the Quick Settings tile to switch network modes.
5. Check device network status in system settings.

Expected Behavior

The app should switch the preferred network mode to the selected configuration (e.g., toggle from 5G/NR to 4G/LTE).

Actual Behavior

The toggle action executes, but the network mode is not applied or changed.

Additional Context

• Shizuku is running and connected properly.
• One UI 8.5 may enforce stricter telephony/hidden API restrictions or altered subscription manager endpoints.

@wiwek13 seems to be an issue between upstream aka legacy Shizuku and One UI 8.5.

THIS alt Shizuku(Plus) project has corrected for it. Try the latest release.

Note: the "Drop-In" version is meant to be a replacement for whatever Shizuku solution you're currently using. The other APK is meant to coexist with your existing solution. I'd suggest the Drop-In version as it's more straight forward and the other is a bit unnecessary at this stage of the project's development.

Be sure to update us with your results if you try it!
