I have posted about this obvious software bug before, but had no response from Samsung
Sometimes the Freesat channels disappear although they are still tuned. The TV has to be unplugged and rebooted. Sometimes more than once. I even re-tuned it and the TV still said "service not available". After several reboots it worked again.
It is blindingly obvious it is caused by a software bug, as is the fact that it does not store a value for the default aerial and defaults to "terrestrial" even if you NEVER use Terrestrial
The software updates are enabled and I have manually updated the TV. There were no updates.
Any updates expected for your clearly buggy & brittle Tizen platform ?
No the SIGNAL is fine, it's a software problem.
The original default yes, but you should be able to set the default aerial in the software.
It is beyond stupid that it switches back to an RF source that has NO SIGNAL away from a live Freesat signal for no reason.
If I use TVplus or YouTube say, that is coming over the Internet NOT from an aerial, so why would the aerial switch to Terrestrial then so that I have to change the aerial to watch Freesat, even though TV plus or YouTube do not use an aerial, it is just poorly written software.
I had a career as a software developer;I know what I am speaking of.
I want a reply from Samsung mate
