Sky Q Voice Control Is Defective
If you discover that your Sky Q voice control is not functioning, there could be some causes. Ensure that your remote’s microphone is active, allowing it to recognise your commands.
If this does not resolve the issue, another factor likely is to blame. Check to see if any nearby electrical gadgets are making noise or interfering with the remote’s connection; if so, try moving them away from the television to see if this helps.
Additionally, you should check the batteries in your remote, as a low battery can create signal interference. Depending on how long you’ve owned your Sky Q remote, you may need to reset or replace it if all other options fail.
