Huawei’s presence in the UK 5G network has long been controversial. The Observer reported that mobile operators are ignoring security fears and working with the Chinese firm.

The Observer understands that Huawei is already involved in building 5G networks in six of the seven cities in the UK where Vodafone has gone live. It is also helping build hundreds of 5G sites for EE, and has won 5G contracts to build networks for Three and O2 when they go live. The decision to use Huawei in the “non-core” parts of their networks – chiefly the radio systems allowing wireless communication – is a gamble for UK telecom operators. They may be left counting the cost if the government bans the Chinese company from any involvement with 5G.

While Samsung is stilling working to get its foldable phone released, others are trying to find new form factors. Techradar reported on rumors that Sony is developing a rollable phone.

Considering the lack of solid evidence to back up these claims, we wouldn’t bet your house on them just yet. They are, however, an intriguing hint about where Sony and the rest of the industry might head next. We’ve previously seen patents from Sony detailing how rollable (and foldable) phone screens could work. We also know that LG – tipped to be supplying Sony with flexible screens – has the expertise to make displays that roll up. Add in the news that the likes of LG and Samsung are apparently busy developing rollable smartphones of their own, and this new rumor about a Sony device starts to sound a lot more credible.
