Hi there! I see you’re getting the “DEVICE SECURITY ISSUE” error on your BPI app while using your Samsung S23 Ultra, even though your developer options are already turned off. Let’s work together to get this sorted out.

Sometimes, this error can pop up due to other settings or apps affecting the phone's security status—not just developer options. Here’s a step-by-step approach you can try:

1. Secure Folder Method:
Samsung devices have a “Secure Folder” feature that isolates apps for better security. Try activating your Secure Folder in your phone’s settings, then open it and add the BPI app inside this folder. Many users have found success in bypassing this error with this method.

2. Check for Conflicting Apps:
Antivirus apps or apps with accessibility permissions can sometimes trigger false security alarms. Go to your phone’s settings, then:
- Disable or revoke permissions for any antivirus or security apps you have installed.
- In Accessibility settings, turn off any apps you don’t critically need.

3. Clear app data and cache:
Sometimes clearing the app’s data helps:
- Go to Settings > Apps > BPI app > Storage
- Tap on “Clear Cache” and “Clear Data”
- Restart your phone and try logging in again.

4. Update or Reinstall the BPI app:
Make sure you’re on the latest version of the BPI app from the Google Play Store. If you are, you can try uninstalling and reinstalling the app to reset anything that might be causing the problem.

5. Check for Samsung Knox or device integrity issues:
The app might be reading some Samsung security feature (like Knox) signaling a problem. Make sure your phone firmware is up to date by checking for system updates (Settings > Software update).

If these don’t resolve the error, it’s often useful to review official BPI advisories or user discussions where similar issues have been tackled. For example, users on Reddit and YouTube have shared fixes involving Secure Folder and permission adjustments1 2.
