Sky Q Firmware
Your main Sky Q box will automatically update its software during the night when connected to the satellite dish. Any Sky Q Mini boxes you have will also automatically update their software during the night, providing they are connected to your main Q box and the main Q box is connected to the satellite dish. New software releases are rolled out to compatible boxes over a period of 2 - 3 months, so your Sky box may receive an update before or after your friend’s box does.
You can check the release of software your Sky Q box is running by going to: Settings > System Info and looking at the “Software Version”.
