Copy and paste the TV app .apk file onto a USB drive and connect the USB drive to your Android box/connected TV.
Find the .apk file on your USB key using a file explorer (most connected boxes have a file explorer application installed by default, but if you use a box belonging to an ISP to the Internet, you may need to download and install a file explorer application manually).
Click on the file to install the application on your device.
Note: Systemethic TV does not request any access to so-called sensitive data on your device (geolocation, access to files, contacts, etc.). In the case of a direct installation via the .apk file, confirmation and/or warning messages generated by Android may appear during download or installation. The appearance of these messages is normal and can be ignored. Depending on the version of the OS used by your box/TV, you may also need to authorize the installation of non-store applications in your device settings before installing the file.
