I wanted to add my experience in case it helps others with the same issue.
I have a 65-inch Sony BRAVIA 8 II (K-65XR8M2). The TV had been performing perfectly, but shortly after the most recent Sony software/firmware update I began noticing subtle but persistent motion judder/stuttering on live television.
My current Android TV build ends in 602080.
I have carried out quite a bit of troubleshooting:
● The problem occurs across multiple terrestrial channels.
● signil quality is 100/100 and signil strength is 90/100, so reception appears to be very good.
● I have tested different Motionflow and Film Mode settings.
● Turning Motionflow completely off changes the behaviour but does not make motion look completely right.
● Motionflow Custom with Camera Smoothness set to 1 improves the problem, but this feels like a workaround rather than a proper solution.
● Changing channel and then switching back has sometimes changed/improved the motion behaviour.
● Streaming content does not appear to exhibit the problem in the same way.
● Most importantly, I did not notice this behaviour before the recent firmware update.
I have raised this directly with Sony Support and my case reference is 29173275. Sony have so far said that the issue is not currently marked as a post-update problem, but they have asked me to carry out further diagnostics so the case can be escalated.
I’m posting here because I’d be very interested to know how many other BRAVIA 8 / BRAVIA 8 II owners are seeing the same thing following the recent update. If you are, it would be useful to share your model, firmware/build number and whether the problem began after the update.
Hopefully, if enough owners report the same behaviour, Sony can identify whether this is a firmware-related motion-processing issue and address it in an update.
