An anonymous reader shares a report: Essential Products has sold an estimated 5,000 phones through Sprint since the gadget made its big retail debut in the United States earlier this month, according to estimates from BayStreet Research. That figure would put Essential, whose maker became a unicorn without shipping handset, well below market heavyweights like Apple and Samsung, which typically sell tens of millions of phones per quarter in the United States. BayStreet tracks shipments of phones and other devices across the United States. Essential representatives didn't respond to requests for comment on the BayStreet estimates. BayStreet also clarified that its 5,000 figure is an estimate of Essential's sell-through (when a customer buys a product from a retailer) rather than its sell-in (when a retailer buys something from a manufacturer). Sprint is the exclusive carrier for the phone; most phones in the United States are sold through carriers. However, Essential also offers an unlocked version of its gadget. Essential, the first major startup from Android founder Andy Rubin's venture capital firm Playground, currently sells the $699 Android-powered Essential Phone through Sprint and promises to release the Essential Home smart-home hub later this year. Essential was named as one of FierceWireless' top 15 startups to watch in 2017.
