Microsoft announces an improved HoloLens, Nubia shows off its "wearable smartphone" and Netflix has a big night at the Oscars. Here's your Daily Crunch for February 25, 2019.

1. Say hello to Microsoft’s new $3,500 HoloLens with twice the field of view

Microsoft has unveiled the latest version of its HoloLens "mixed reality" headset at MWC Barcelona. The HoloLens 2 features a significantly larger field of view, higher resolution and a device that’s more comfortable to wear. In fact, Microsoft says the device is three times as comfortable to wear.

HoloLens 2 will be available later this year in the United States, Japan, China, Germany, Canada, United Kingdom, Ireland, France, Australia and New Zealand for $3,500.

2. Nubia’s ‘wearable smartphone’ might be the next step for flexible displays

It’s still bulky, so far as smartwatches go. But at the very least, you could probably walk down the street in the thing without stopping traffic.

3. Netflix’s ‘Roma’ wins three Oscars, including Best Director (but not Best Picture)

It was a good night for Netflix, and for "Roma." But I'm still mad that "Green Book" won the big prize.

4. New microSD format promises insane transfer speeds, better battery life

The SD Association has announced the new microSD Express format, which will allow future mobile devices to consume and create content at even faster speeds.

5. New flaws in 4G, 5G allow attackers to intercept calls and track phone locations

This is the first time vulnerabilities have affected both 4G and the incoming 5G standard — which promises faster speeds and better security. But the researchers say that their new attacks can defeat newer protections.

6. The Google Assistant gets a button

Traditionally, the Google Assistant always lived under the home button on Android phones. But LG, Nokia, Xiaomi, TCL and Vivo are about to launch phones with dedicated assistant buttons, similar to what Samsung has long done with its Bixby assistant.
