Samsung's first foldable-screen smartphone may be something of a novelty, but the company demonstrated Tuesday that it plans to keep going until such devices are mainstream.

Why it matters: There's a lot of interest in foldable devices from hardware makers eager to shake up a sluggish smartphone market, but the early products have been pricey and delicate.

While biometrics can offer added security, two separate issues highlight limitations of the technology, especially when used as the sole means of locking a smartphone and user accounts.

Driving the news: Samsung says it is working on a software update for the Galaxy 10 after a user in Britain discovered that using a protective case, in some circumstances, will allow any fingerprint to unlock the device.
