Hello Robby68, Thank you for sharing your thoughts about the remote and Alexa compatibility of the TU690T Samsung TV. Your feedback will be shared with our internal teams. Alexa works with the TU690T and is not built in. What this means is you will need to have an Alexa echo device nearby and then pair this device with your TV. From here you will be able to tell your Alexa Echo to control your TV. If we can help with anything else, please call us at 1-800-SAMSUNG, 8 AM - 12 AM EST, seven days a week. LiveChat with an agent, as well as manuals, software, and warranty info, can be found at the ‘Support’ link on our Samsung website. ~ Samsung Advisor
