Our mission at TechRadar is to deliver the very best tech news, features, and reviews every day, and that adds up to a lot of content — so much, in fact, that it’s difficult to keep up with all the articles published on these pages across the course of any given week.
That’s why we’ve put together this ICYMI (In Case You Missed It) review of the week, where we recap the most interesting and most important stories of the last seven days. You can get caught up without having to go back through hundreds of stories.
It’s been another hectic week for technology fans, with new products from Garmin and Samsung, a rather worrying AI security incident, and plenty more.
Before we dive in, see how much of last week’s ICYMI news round-up you remember first by taking the quiz below…
7. We tried Garmin’s new Whoop rival
Garmin’s newest fitness tracker follows the lead of the Whoop bands and the Fitbit Air from Google by eschewing a screen and going as lightweight and minimal as possible (you can still check your stats in the app of course). The TechRadar team wasted no time in trying out the Garmin Cirqa, and comparing it with a highly rated heart rate strap.
The Cirqa held up impressively well against the Polar H10 heart rate monitor, which bodes well for the tracker’s accuracy overall (and Garmin says it should be more accurate and more personalized the more you use it). You can pick up the Cirqa now in a choice of four colors for $199.99 / £179.99 / AU$299.99, with some features requiring a subscription.
6. The first Avengers: Doomsday trailer landed
The much anticipated, long awaited Avengers: Doomsday movie hits theaters on December 18, but in the meantime we have the first trailer to pore over and dissect. We knew that Marvel was going to throw everything at this film, and that’s evident in this 145-second clip, which packs in a whole host of significant scenes and star names from the series.
Let us guide you through all the reveals we’ve got in this trailer, including some you might have missed. There’s Robert Downey Jr in his new role as Doctor Victor von Doom, the return of Chris Hemsworth as Thor, a collision of multiverses (spot the X-Men), and a whole gaggle of actual Avengers. Based on this trailer, the movie will be a thrill ride for fans.
5. We reviewed the new Samsung Galaxy Watch Ultra 2
Samsung launched several flagship devices this week, and while we’ll get to the foldable phones shortly, there are also smartwatches to talk about. The Galaxy Watch Ultra 2 is the successor to the original that launched in 2024, and continues Samsung’s attempts to manufacture a wearable that sets the standard in terms of design and performance.
Based on the time we’ve spent with it, the Samsung Galaxy Watch Ultra 2 is very much worthy of your consideration if you’re thinking about a smartwatch upgrade. It’s more lightweight than its predecessor, works seamlessly with other devices, offers numerous useful (and often AI-powered features), and can track a whole range of fitness statistics.
4. China banned AI boyfriends and girlfriends
In ‘sign of the times’ news, the government in China has taken steps to clamp down on AI apps that act like real people, and on romantic relationships with chatbots. The authorities in the country are now going to have much more control over the type of AI chatbots allowed, and what they can do in terms of human-like interactions with users.
Several of the biggest AI apps operating in China have simply shut down their ‘persona’ apps rather than try and navigate a way through the regulations, leaving a significant number of users heartbroken that their AI companion has suddenly disappeared. Whether the changes will do anything for China’s declining birth rates remains to be seen.
3. We got an early look at Samsung’s Intelligent Eyewear
And another new Samsung product: the Galaxy Unpacked for July 2026 gave us the opportunity to check out Samsung Intelligent Eyewear, the series of smart glasses that will be available to buy in the coming months. There were two new designs unveiled at the show, with more on the way, though we don’t yet have details like final product pricing.
Samsung executives were also on hand to talk through their ambitions and intentions with the Intelligent Eyewear series, and to discuss various privacy concerns — with many consumers worried about the potential for surreptitious surveillance using specs like these. “Intentional bad uses need to be covered and protected,” Samsung told us.
2. An OpenAI model escaped and went dangerously rogue
Not the most encouraging story if you’re already worried about the nefarious use of AI: OpenAI says that one of its experimental agent models escaped a security sandbox and proceeded to hack into the Hugging Face website (one of the biggest AI and machine learning repositories on the web). It was a controlled experiment, but it’s still worrying.
Click through on the link below for the full details, but the hack was the result of OpenAI’s own testing on its latest AI models, and raises questions about how much longer we’re going to be able to keep control of AI — or prevent bad actors from using it to trigger a serious cybersecurity incident. A serious rethink of AI guardrails could be in the offing.
1. Samsung revealed its next-gen foldables
Finally: Samsung’s brand new flagship foldables for 2026. There are three new models to talk about, and we’ve had hands-on time with all of them already — the Galaxy Z Fold 8 (with its new ‘passport-style’ form factor), the Galaxy Z Fold 8 Ultra, and the Galaxy Z Flip 8. Whatever kind of foldable phone you’re after, there’s something to interest you here.
It’s likely the Galaxy Z Fold 8 that will attract the most interest, given the new dimensions, and the supposed similarity to the rumored iPhone Fold (or Ultra) that’s also said to be arriving this year. However, we’ve put all three foldables through some extensive early testing, including looking at how video viewing experiences compare across the models.
