Roku OS 8.2 is a software update rolling out to all Roku TV™ models over the coming weeks. It includes bug fixes and updates to improve your entertainment experience when using a Roku TV.

@RokuShawnS can you please provide an update for us regarding broken Dolby Vision (i.e. backlight dimming) TCL Roku TV models? It would appear as though this has issue has gone unaddressed for nearly a month.

has anyone else had problems with Dolby Vision since the 8.2 update? I have a TCL and before the update all was good but since it is way too aggressive , goes from super bight to very dim , for example a scene with two people talking indoors and one has a light source behind them,  as the scene switches between them one with light source is super bright and one without is very dim, expect it to be different and always was but now the difference is way too extreme. Have factory reset and checked all settings (same as they were before) but has not helped,its now way to distracting to enjoy the show .have only checked on streaming content but is same on Netflix , amazon etc. any ideas?

I bought the TCL55S517 a few weeks ago, and I'm having the exact same problem.  It's happening on all Dolby Vision content.  HDR is working fine.  I'm currently on Software Version 8.2.2 Build 4120-30.
According to the Advanced Picture Settings, the Dynamic Contrast feature is disabled and it says that "Dolby Vision is controlling the backlight".  I wish there was a way to turn this off.

To RokuShaunS,
Can you please post a status update on what is being done and when these OS 8.2 issues will be resolved??? My 4K TV was unable to function throughout all of the holidays and football bowl season.  This is really frustrating.

My tv on 8.2 is still not streaming sling or Hulu.  Weird enough it will stream YouTube just fine most times but the vast majority of my tv watching is via the other 2 apps.  However I am back to using my old roku 2 that used to be on OS 8.1 and worked flawlessly if a bit slow due to the processor.  But it was doable.   That roku updated itself to OS 9.0 a few weeks ago which concerned me very much at first because I was leaving it unplugged when not being used so it wouldn't update to 8.2 and become a brick too.   But it caught me one day and updated.  But it updated to OS 9.0 and lucky for me 9.0 seems to stream fine on the old roku 2.  So I'm (Im)patiently waiting for my roku tv to update to 9.0 with the rose colored hope that it will resolve this stupid 8.2 OS that has rendered my tv to being a monitor for the last several months.  

Anyone else on OS 9 now?   Is that working for you?   I know this topic is about a different app or function not working but I've been jumping in and following it because my problem is also 8.2.

After not much change for over two months now for 8.2, I have already moved on to hoping Roku OS 9 will resolve the issues and not making anything worse. I started pulling an ethernet cable through my house to connect the TV wired which helps and was considering buying a Fire Stick as backup as some folks on the web suggest as apparently every new release of Roku OS might hit your specific device with issues. So keep hoping on OS 9, which should arrive for the TVs between now and end of March. Keeping fingers crossed.

Received 8.2 on my TCL TV tonight. So far, it appears that the DD+, DTS issue has been fixed. I will confirm when I get more sources and formats through it however. Otherwise, everything appears to be the same. I did not have to reset any settings, including picture, so that was a nice touch. I don't really notice any new features, but I wasn't looking either.

Edit: OK. DD+, DTS output from TV is not working properly. In fact, it may be worse. To recreate, connect TV to AVR with HDMI using ARC. Set TV audio out to DD+, DTS. Send any STEREO (two channel) signal (the Pandora music app for example) to the AVR. Set the AVR to output STEREO. What you will hear is what is commonly referred to as the difference signal, or L-R )left minus right). Very odd. The update (8.2) may be worse, because now not only is the signal L-R, but there is a severe "pumping" of the signal. 

Now, in order to fix the problem (so you can listen to Pandora in stereo, for example), just change TV output to DD, DTS. Problem goes away. It is not an HDMI cable issue. It is not a Pandora issue. It is not an AVR issue. The fact that everything works as expected in DD, DTS (no +) mode, tells me its a Roku software implementation issue. Oh well, maybe next update.

I have the same issue on my TCL 55R617  with firmware 8.2.2 hooked up to a 2011 Denon AVR. DD+ works fine from my old 2011 Samsung Plasma and my KM8 Android media player but the Roku produces a low pumping/chirping output in the AVR.
