Hello @user_he863n! Thanks for commenting your shared concern. This is a known issue that our engineers are working hard to resolve as quickly as possible. We'll try to let everyone know when we have any updates to share! Thank you very much for your patience.

Either rollback whatever update you pushed, issue us all bill credits or Give us [Edited: Inflammatory]

My exact reply coming from a 30 year IT vet....roll back or issue us a no cost box [Edited: Inflammatory]

@Fraz75

I am football fan and would not be happy if I could not stream my tv services, can you give me little detail on what is happening when try & stream our services from your Samsung device  

Long loading screen of 3 dots then A error message pops up saying " we're sorry. Due to an issue with Samsung's firmware, we're currently working to address a problem with live tv within xfinity stream on certain samsung 2021 tv's"

error:tvapp-00148

it refuses to play any show. Roll back whatever update your techs did. Give us free cable boxes for our inconvenience or a bill credit for every day its unusable. Because why am i paying for a service i cant use. If this isnt fixed by superbowl sunday i will be calling in and asking for retroactive bill credits.

Thank you for reaching out to us @user_dns9zd!

In the meantime, please continue using other eligible devices in the home that are not Samsung while our engineers work to resolve this issue. Thank you so much for your patience while we work through this for you!

After getting off the phone with xfinity for the issue we have all been going thru, I now have a new error code which is Tvapp-00815. My On Demand being taken away is linked to the TVAPP-00148 as I am being told. This just started and hour and 15 minutes ago. My WiFi went out and I canned as my on demand was not working either. I was told that this is on Samsung again. I am trying to let my fellow Samsung people know that this issue is getting bigger by the day with Xfinity taking no responsibility in their end. I am without WiFi-except on my T-mobile phone(can't get WiFi on my laptop), no live tv and no On Demand. This is beyond ridiculous. Hoping to help whoever else is going thru this. I am paying for a service that I have none of. I can't even get a credit for not being able to access anything.

Finally fixed the Samsung/Xfinity stream issue!!

That is Xfinity Stream running in the background... 🥳

Call the number to Samsung that is now listed on the error code. They helped us resolve the issue. You'll need a flash drive, and they'll assist you to download the update, and guide you step by step to install it on your TV. We asked why they weren't doing an across the board update for everyone, and the representative told us Samsung would be, but it'll probably take a month. Hope this helps :) 

@user_fjxa0u​ the resolution was posted by @XfinityKatie on the marked Official Solution for this thread (see page 1). 

What update are you talking about and where did you get it?

Samsung has an update. You need a flashdrive to download it from their website, and then you'll have to plug the flash drive into your TV to manually install. The Samsung representative we spoke with gave us step-by-step instructions to download the update onto the flashdrive, as well as instructions to manually install it into our tv. The entire process took about 10-15 minutes. I don't have the number we called since our TV is now working and we no longer see the error code, but the 800 number to contact Samsung was noted with the error code when we were checking our tv the other day to see if it was working. The error code had come up as it had been, but there was now additional information listed with the error code, including the 800 number I've mentioned. 

Thank you so much! This worked for me. I have the model QN65QN90AAFXZA and the USB update from Samsung fixed my xfinity app problems. :) 

Spent an hour with Samsung support this morning, and they don’t have a usb downloadable fix for my models of TVs. So we are still out of luck with live tv, unless we want to spend even more money on a Roku. Almost three weeks now…… :/

@user_ooieyf from the marked "Official Solution" on this thread (page 1)"

1. You can update your TV’s firmware manually. (You’ll need the model number of your TV and a USB flash drive.)
   1. Go to https://www.samsung.com/us/support/downloads/
   2. In the Search your product search bar, enter TV’s model number
   3. Under Firmware, you should see and click on How to update USB firmware (this will open a new webpage with this header: Update the software on your Samsung smart TV or Monitor)
   4. Then choose and follow the Update using USB instructions

Roku worked for me. Try that

@user_pzc2rw​ did you review the marked "Official Solution" on this thread?

@user_2hbh6s​ I think there may be some confusion, this is not an Xfinity issue, see this thread's marked Official Solution". I think you need to take up your concerns with Samsung.

@valhossu​ it is not Samsung fault , look at all your other apps it’s just Xfinity correct ? 

Hey @valhossu,

Thank you for visiting our official Xfinity Community Forums support page. Please accept my most sincere apology for the experience you have encountered with the Xfinity Stream application on Samsung SmartTVs. We would like to let you know that this is not an Xfinity issue, but an issue with the firmware in the Samsung SmartTV. Samsung is working to deploy a fix within the next 10 days hopefully that should automatically fix the issue. 

We do have a few known workarounds that you can use to try and enjoy your Xfinity content on your television. One possible workaround is manually updating the television by visiting the Samsung support page. You will need the know the model of the television as well as a USB drive for the television's firmware. You can find instructions and more by visiting samsung.com/us/support/downloads.

Alternatively, you can play Xfinity content using a mobile device, and then, on your home WiFi network, use Bluetooth to cast the programming to your Samsung SmartTV.

We apologize that the Xfinity Stream app is not working as seamlessly as we would like, but a fix should be coming out soon to help resolve these issues.

Hello, @user_3eau8r. Thanks for posting on our community forums. Are you experiencing the same error message with your Xfinity Stream App on your Samsung TV? If so, there is a workaround that has worked for most of our users. You can download the latest firmware through the Samsung website. You will need the know the model of the television as well as a USB drive for the television's firmware. See the instructions and more by visiting Samsung Support. I hope this helps!

@user_68fa1f​ I just looked this up and my TV is already loaded/updated with the latest 2210 update. 

@user_fjxa0u​ Mine previously noted an update of 2201 and every time I tried to manually update via the settings screen, it would note, no new updates available. It wasn't until I went to the Samsung site and found the Version 2501.1_2210.0. It might not hurt to try and download the one noted on the Samsung site just to make sure. Just a thought.

Unfortunately, this doesn’t work for us. We plug in our model number but the firmware update isn’t an option. Maybe they haven’t worked out an update for our model yet. We talked with Samsung, and they were worthless. We are beyond frustrated!

@user_68fa1f​ same for me. I downloaded the update to a USB drive, but TV kept saying no update available when I plugged it in

@user_ooieyf​ this is an Xfinity issue all other apps on your TV work correct 

I downloaded the firmware from the Samsung site.  It REVERTED the firmware to a previous version.  Funny how Samsung is being more responsive than Xfinity in resolving this situation by reverting their firmware rather than Xfinity who have NOT correct their coding problem in their software QUICKLY
