I upgraded my 65" TV yesterday (4/5/2026) to the One UI Tizen (9.0 I think). Since then neither of my TV remotes Mute button work, either the Samsung Remote or my Amazon Fire Stick (which had worked). The Smart Things app which had worked, no longer has a working Mute feature. I've tried all sorts of fixes AI has suggested none work. I assume others are affected and there will be a patch soon.
Problem resolved. I had this same Mute issue but I found out how to resolve it. Here's what I did:
Go to the Home page on TV. Then scroll over to "Settings" on the left menu.
Select "Support"
Select"General and Privacy"
Scroll all the way to the bottom and select "Reset Factory Data"
It will ask for a PIN. The default is "0000" if you've never changed it.
Resetting the data will leave the new update in place, but remove all of your setup you did when you unboxed the TV. Yes, this is annoying and will take some time, but if you log in with the same Samsung account it should use the backup it made during the update.
I upgraded both of my 50 inch TVs another new upgrade easier pictures of more clearer and I got 4K TVs yeah my phone just Samsung let me tell you I love the products everything you guys do with them
We also did the update today, 4/6/26, and the mute is also not working on both of our Samsung remotes. This is a bug that Samsung needs to fix quickly!

Thanks Douglas. That worked for both my remotes. Fortunately I never change any color/contrast/blurring type settings, so other than bopping through the START SETUP screens again (I just clicked the right arrow button, NEXT) after getting caught in a "change password" loop for a bit, your suggestion worked perfectly. ๐
Dear Douglas53. Thanks for the advice. Many others have similar advice. Unfortunately, I have done everything except "reset factory data" since the TV complains that the menu option is not available. I did a "reset' in maintenance mode which completely neutered the TV. Still no mute and I lost all the authentication information for my streaming services. BAD Samsung. Three hours into troubleshooting to get an update that changed the shape of some menu items and add some nag screens.
