Salesforce's outlook falls: On Tuesday, the company reported its fourth quarter earnings, and although it beat analyst estimates, it also issued a lower guidance for the following quarter than expected. Salesforce executives told analysts that because the fourth quarter of the year is usually the company's strongest, it can't expect the same results in the next. Nevertheless, it also increased its guidance for the full 2017.

Early look at the Samsung Galaxy 8: The Korean tech giant is expected to unveil its latest smartphone in a month, but a photo of it has already leaked. The phone doesn't appear to have physical buttons and is an update on the old Galaxy. With that said, no word yet on the phone's software.

Why it matters: It's been a tough year for Samsung. The company's heir apparent was just indicted on bribery charges, it had to recall its Galaxy Note 7 phone because of faulty batteries, and this year it's decided against unveiling its Galaxy phone at the Mobile World Congress conference in Barcelona.

The story has been updated to clarify that Salesforce's Q1 guidance was lower than analyst expected, not than a previously announced outlook.
