The dual-screen device will also have an 11-megapixel camera, a Surface Pen, 6GB of RAM, a choice between 64GB or 256GB of storage and a 3,460-mAh battery, the report said.
Microsoft didn't immediately respond to a request for comment.
Microsoft announced the Surface Duo, a dual-screen device in October last year. It will be its first phone in years, though Microsoft says the Duo isn't actually a phone. It's set to launch during the holiday season this year, though the Windows Central report said that timeframe may be moving up.
