To use it you must have your phone root, have installed with the root the “magisk” application and install the hack in its latest version (same number as the current GT version, the current one is 3.24 but the hack is only up to 3.23 you have to wait for it to be updated) also I am not sure if it is required but install also the “LSPosed” (I am not an expert or anything but I hope to help)
