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

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

What a far-field mic does →

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.

This model is still receiving firmware/platform updates.

What that actually means for your TV →

Amazon's Software Security Updates page lists the Amazon Ember 4-Series and Fire TV 4-Series 43, 50 and 55-inch (2025 release) with security updates until at least 31 December 2030, or at least four years from purchase if bought new from Amazon, whichever is later. Amazon says this isn't a guarantee of how long the device will last.

This model has Amazon's ACR feature (branded "Automatic Content Recognition"), which analyses on-screen content — including over HDMI — to identify what's playing.

What ACR is and how to turn it off →

Amazon's help page says that when ACR is enabled on a Fire TV smart TV, Amazon identifies what you watch through connected devices such as a cable box, and that it is managed at Settings → Preferences → Privacy Settings → Automatic Content Recognition. Amazon doesn't say whether it is on by default. Enabling it on one Fire TV device doesn't enable it on others.
