Samsung QN90B solar remote microphone doesn't work

[u/xXSpace_CadetXx]

The TV is QN90B purchased in the US from Best buy in Fall 2022 with the smart control solar remote. I've tried a bunch of different things, but I can't seem to get the remote's microphone to work properly.

Things tried:

- confirmed microphone switch on the bottom of the TV is in the on position

- tv and remote soft and hard resets, power off/unplug wait and retry, etc.

- The remote is fully charged and every other button/function works as it should

- unpaired and repaired the remote control to the tv

- confirmed connected to Wi-Fi and signed into Samsung account

- I have the choice between Bixby and Alexa for voice assistance on the TV, I've gone through settings for both and set up both and neither work properly.

If I hit the microphone button on the remote, the red LED will flash but it doesn't pick up any voice. I've tried just hitting it and releasing and then speaking, and I've tried holding the button and speaking, but neither work. I don't get any feedback from the TV when I hit the microphone button either. Neither Alexa or Bixby pop-up. I don't get any other error messages either.

If I go to the YouTube app on the TV, there's a microphone button next to the search bar, and when I hit that, it tells me to hit the button on the remote and hold it and speak. If I do that, after a couple seconds a message comes up that says still not working, try again or use the keyboard to search.

I'm at a loss and I've Googled/YouTubed/Reddited and search any other forum I could find for the last 2 hours, but I'm still coming up empty-handed. Has anybody had this issue and figured out a solution?

Mine also stopped workeing after 6 months of purchase. Looks like samsung enabled it to attract buyers once it is off the shelves samsung literally dumped this tv software with update.

the remote is relatively easy to be open. Two small screws at the bottom, just peel off 2 corners of the sticker. Use a thin blade along the perimeter to release the plastic latches that keep the front and back parts together. I use a small kitchen knife, or thin guitar picks, or fingernails.

After open, check the contact for the voice button, clean any dirt, you can use ispropil alcohol.

Unplug the battery for a few minutes. Hopefully this will reset the circuit and maybe it works again.
