Amazon Ember 4-Series / Fire TV 4-Series (2025, UK)

LED · Fire TV · 43, 50, 55″

Built-in far-field microphone

No TV mic

This model has no built-in far-field microphone — voice control goes through the remote.

Amazon's device specification page lists "Mic: Not Supported" for this model, so the TV itself has no microphone. Hands-free Alexa works only through a linked Echo device; otherwise voice control uses the remote's microphone button.

Automatic content recognition (ACR), including over HDMI

Unverified

Whether this model runs ACR hasn't been confirmed from a citable source yet.

What ACR is and how to turn it off →

Amazon documents its Automatic Content Recognition setting on US help pages only; there's no UK version of that page. Amazon's UK privacy FAQ says smart TVs with Fire TV can send Amazon information on your use of broadcast live TV through the aerial inputs, with an opt-out under Settings → Preferences → Privacy Settings. Checked 19 Oct 2026.

Interest-based AdsAds continue, less personalised

Tells apps that use the device's advertising ID not to use it to build ad profiles or show you interest-based ads. Ads continue.

Amazon's privacy FAQ covers Fire TV devices from other brands too. Same path in the UK and US.

No setting to turn them off is documented. Amazon's Fire TV privacy FAQ describes Interest-based Ads as telling apps that use the device's advertising ID not to use it to build ad profiles or target interest-based ads; it doesn't say the ads stop.

These settings cover ads in the TV's own menus, not ads inside individual apps. Menus can change with software updates, so check again after your TV updates.
