Say goodbye to the Galaxy's home button and hello to an infinity display. Samsung (SSNLF) unveiled the Galaxy S8 and S8+ at an event in New York on Wednesday. The new phone displays are bigger than the Galaxy S7 and S7 Edge and they have curved screens that flow onto the sides. For the first time on a Samsung phone, the physical home button is removed entirely. (This is already the case on most other Android devices). The S8 will be the first phone to feature Bixby, Samsung's new AI assistant. Despite a crowded voice assistant market, Samsung insists Bixby is "fundamentally" different from competitors like Apple's (AAPL, Tech30) Siri and Amazon's (AMZN, Tech30) Alexa.
