An image of the 650 has been leaked by @evleaks, a reliable source of smartphone pictures before they are officially available.
The 650 is a mid-range handset, with a 5-inch screen, 1GB of RAM, and 8GB of storage, according to Neowin.
Microsoft sold just 4.5 million Lumia handsets in the three months leading up the January, a sharp decline over the previous year.
The company has reportedly been working on a Surface Phone, which would resemble the Surface tablets. However, it’s unclear when Microsoft would introduce the device or who the target market would be.
The Lumia 650 will cost £199 ($280) in the UK, according to a mobile carrier that erroneously posted the details of the phone.
Business Insider has reached out to Microsoft to ask about the leak.
