I was also one of the people who bought a Samsung TV that didn't have ads, then suddenly had ads. That also got me an instant refund with no questions.
In both cases I printed out a copy of the product website where they published the changed features (eg the changelog or PR release or whatever I could find) and I also printed off a couple forums/media-articles talking about the changes. The stores didn't question it or have any issues with refunding me, I guess they just then file with the manufacturer for their own refund.
When I turned it on, there was a big dim spot on the top edge of the panel. It had to be exchanged.
However, you are not forced to apply the update. So that's a bit different.
So how does this affect smart phones? ;-)
We also get longer warranties than most other countries. Even if a brand says you only get a 1 year warranty, our consumer protection laws say a warranty has to apply for "as long as seems reasonable", so for most technology that's 2 years.
Warranties are separate from your automatic consumer guarantees. The consumer guarantees which apply regardless of any warranties suppliers sell or give to you, apply for a reasonable time depending on the nature of the goods or services. This means consumer guarantees may continue to apply after the time period for the warranty has expired.*

You can ask for a replacement or refund if the problem with the product is major.
What is a major problem?
A product or good has a major problem when:
it has a problem that would have stopped someone from buying it if they’d known about it
it has multiple minor problems that, when taken as a whole, would have stopped someone from buying it if they’d known about them
it is significantly different from the sample or description it is substantially unfit for its common purpose and can’t easily be fixed within a reasonable time
it doesn’t do what you asked for and can’t easily be fixed within a reasonable time; or it is unsafe.

There is no specific time when the consumer guarantees no longer apply to products. They may apply even after the manufacturer's warranty period has past. The length of the consumer guarantee period depends on a number of factors including:
how much time has passed since the consumer bought the product the type of product how a consumer is likely to use the product the length of time for which it is reasonable for the product to be used the amount of use it could reasonably be expected to tolerate before the failure becomes noticeable.
