-If you are using [the *Secure folder* on your Android](https://www.samsung.com/uk/support/mobile-devices/what-is-the-secure-folder-and-how-do-i-use-it/)(this applies mainly to Samsung devices), you may face some difficulties when installing the HTTPS certificate. The thing is that the *Secure folder* has its own space where the certificates are stored. However, if you do everything according to the instructions [described here](../../overview#https-filtering), the certificate will be installed into the main memory and will play no role for your ad blocker in the *Secure folder*. To solve this problem and install the certificate for your AdGuard for Android into the *Secure folder's* storage, please follow these instructions:
