Microsoft is expected to announce at least two new smartphones at an event next month. We’ve already heard plenty about the upcoming Lumia 950 and Lumia 950 XL, but a new leak reveals even more about the two devices along with a third upcoming Windows 10 handset.

A handful of slides leaked by Facebook page Forever Nokia Latinoamérica reveal a full list of specs and features for all three phones. It looks like the Lumia 950 will offer a 5.2-inch Quad HD display, a 20-megapixel rear camera with optical image stabilization, a 5-megapixel front-facing, 32GB of expandable storage, a 3000mAh battery and a Snapdragon 808 processor. Meanwhile, the beefed up Lumia 950 offers similar hardware, but with a 5.7-inch frame, a 3300mAh battery and a Snapdragon 810 chip.

Both flagship Lumia phones may also feature Qi wireless charging, a reversible USB-C port and an Iris scanner for Windows Hello biometric security. As for the design, it looks like Microsoft will opt for a classic Lumia style, offering a plastic handset with a matte finish in white or black.

If you’re looking for something on the cheaper side, Microsoft appears to be launching an entry-level option as well. The Lumia 550 packs a 5-inch 720p display, an unnamed quad-core Snapdragon processor, a 5-megapixel rear camera, a 2-megapixel front-facing shooter, 8GB of storage with microSD support, 1GB of RAM and a 1905mAh battery. It’s unclear if the device will offer any of the high-end features included with the Lumia 950 series, though that seems unlikely.

It’s also unclear if the Lumia 550 will get any time onstage next month during Microsoft’s big event. The company is also expected to unveil a new Surface Pro 4 and a second-generation Microsoft Band, so there may not be much time for a third, less exciting smartphone.
