## HTTPS filtering
Nowadays most websites work via HTTPS, the web protocol where the last S letter stands for "secure". It happened so that advertisers use it as well, this is why [HTTPS filtering](https://kb.adguard.com/en/general/https-filtering) is crucial for a modern ad blocker.

> To be able to filter HTTPS traffic, AdGuard needs to install a certificate into your device's user storage. On older versions of Android OS this was done automatically during the onboarding process or later via AdGuard settings, and it only required a couple of taps. Unfortunately, on Android 11 automatic certificate installation is no longer available. Now a [manual installation](https://kb.adguard.com/en/android/solving-problems/manual-certificate) is required.

To be able to filter HTTPS traffic, AdGuard needs to install a certificate into your device's user storage. On older versions of Android OS this was done automatically during the onboarding process or later via AdGuard settings, and it only required a couple of taps. On Android 11 and later automatic certificate installation is no longer available. Now you need to install the certificate manually.
Here is the installation instruction:
1) Go to the app's main screen and tap *Turn on* next to the *HTTPS filtering is off* message (it will be highlighted in red if AdGuard certificate is not installed yet)
2) A new screen will appear, tap twice on the *Next* button and then on *Save it now* when prompted to download an AdGuard certificate
3) After the certificate is downloaded, you will see a new screen. Tap on the *Open security settings* button there
4) This will bring up system settings. Scroll down to *Advanced*, open it and then tap on *Encryption & credentials* (these settings may be called variously on different devices — the main thing is to choose advanced settings)
5) Tap on *Install certificate* and then on *CA certificate*
6) A warning message will appear. Read through it and tap *Install anyway* to proceed
7) Select the recently downloaded AdGuard certificate. A *CA certificate installed* toast message should show up
8) The AdGuard certificate is successfully installed and HTTPS filtering is working now!
>If you update from Android 10 to Android 11, there's a chance that already installed certificate will still be accepted. Otherwise, the *HTTPS filtering* string on the main screen will be red and you'll need to go through the same process of reinstalling a certificate manually.
In case you have problems with the certificate installation, read [this article](https://kb.adguard.com/en/android/solving-problems/manual-certificate) or contact our <a href="mailto:support@adguard.com"support team</a>.
**We want to emphasize that the AdGuard ad blocker will work even without HTTPS filtering. However, it won't be able to properly filter ads on sites that use the HTTPS protocol. So if you want to use the full functionality of the app and get the best ad filtering quality and processing speed, we recommend you to activate HTTPS-filtering.**

To be able to filter HTTPS traffic (which is extremely important as most ads use HTTPS), AdGuard needs to install a certificate into your device's user storage. On older versions of Android OS this was done automatically during the onboarding process or later via AdGuard settings, and it only required a couple of taps. Unfortunately, on Android 11 automatic certificate installation is no longer available. Now a manual installation is required.

To manually install AdGuard certificate:
If this is the case for you, and you have to install the certificate manually, in most cases you will not encounter any difficulties or problems. But some obstacles may still arise, let's look at them in detail.
1) Go to the app's main screen and tap on *HTTPS filtering* (it will be highlighted in red if AdGuard certificate is not installed yet)
## Certificate installation in a "Secure folder"
2) Enable the switch at the top
If you use the *Secure folder* on your Android (this applies mainly to Samsung devices), you may face some difficulties when installing the HTTPS certificate. Let's assume you want to install it for AdGuard app, which is located in the *Secure folder*. You're doing everything properly, according to the instructions, but nothing actually happens — the HTTPS filtering is still turned off. Why is this happening? The thing is that the *Secure folder* has its own storage where the certificates are stored. However, in case you do everything according to the instructions, the certificate is installed into the main storage and plays no role for your ad blocker in the *Secure folder*. So, in order to resolve this issue and install the certificate for your AdGuard for Android into the *Secure folder's* storage, follow this instruction:
3) A new screen will appear, tap twice on the *Next* button and then on *Save it now* when prompted to download an AdGuard certificate
4) After the certificate is downloaded, you will see a new screen. Tap on the *Open security settings* button there
5) This will bring up system settings. Scroll down to *Advanced*, open it and then tap on *Encryption & credentials*
6) Tap on *Install certificate* and then on *CA certificate*
7) A warning message will appear. Read through it and tap *Install anyway* to proceed
8) Select the recently downloaded AdGuard certificate. A *CA certificate installed* toast message should show up
9) The AdGuard certificate is successfully installed and HTTPS filtering is working now!
>If you update from Android 10 to Android 11, there's a chance that already installed certificate will still be accepted. Otherwise, the *HTTPS filtering* string on the main screen will be red and you'll need to go through the same process of reinstalling a certificate manually.
1. After installing the application and connecting to VPN tap "Turn on" next to the "HTTPS filtering is off" message.
2. Tap "Next" —> "Next" —> "Save it now" —> "Allow".
3. Save the certificate (at this stage, you can rename it to make it easier to find).
4. After the "How to install a certificate?" screen appears, DO NOT tap "Open Settings".
5. Minimize the application and go to the secure folder.
6. Tap the three-dot menu and go to additional security settings.
7. Tap "Install from memory" —> "CA certificate" —> "Install anyway" —> Enter a graphic key/password/fingerprint —> Find the saved certificate and select it.
8. Return to the AdGuard application and close the screen "How to install a certificate?" by tapping the cross button.
9. Done! The certificate has been installed.
