Certificate installation in a Secure folder

info

This article is about AdGuard for Android, a multifunctional ad blocker that protects your device at the system level. To see how it works, download the AdGuard app

If you install AdGuard in the Secure folder on your Android device (this mainly applies to Samsung devices), you may have difficulty installing the HTTPS certificate. The Secure folder has its own storage space for certificates. However, if you follow the regular certificate installation instructions, the certificate will be installed in the main memory and will not affect your ad blocker in the Secure folder. To install the certificate for AdGuard for Android in the Secure folder’s storage, follow these instructions instead:

1. After installing the app and connecting the local VPN, tap HTTPS filtering is off on the main screen.
2. Tap Continue → Next → Save certificate.
3. Save the certificate (at this stage, you can rename it to make it easier to locate it later, which you will need to do).
4. After the Installation instructions popup appears, DO NOT tap Open Settings.
5. Minimize the app and go to the Secure folder.
6. Tap the three-dot menu and go to Settings → Other security settings.
7. Tap Install from device storage → CA certificate → Install anyway.
8. Confirm installation with your graphic key/password/fingerprint.
9. Find and select the previously saved certificate, then tap Done.
10. Return to the AdGuard app and navigate back to the main screen.
11. Done! The certificate has been installed.
