10 things you need to know today: March 30, 2017

Samsung unveiled the new version of its flagship smartphone, the Galaxy S8, in the company's first product introduction since its disastrous recall of the Note 7 last year after some of the devices caught fire. The company is depending on the Galaxy S8 to put the Note 7 debacle behind it, and face off against tough competition from Apple and Huawei. The new device offers a Siri-like voice assistant, Bixby, and a bevel-less "infinity" display. "The S8 is unquestionably a strong product but Samsung must now deliver a faultless launch to move on from the difficulties of 2017," said Ben Wood, chief of research at CCS Insight, in an email to CNBC. The phone's official release date is April 21.
