Lenovo has officially announced the Motorola Moto X4 at IFA 2017 in Berlin. The handset is a mid-range Android smartphone featuring a set of dual cameras on the back and features integration of Amazon’s Alexa digital voice assistant.

The Moto X4 features 5.2-inch full HD IPS display layered with Gorilla Glass 4. The device features a metal and glass design, with an overall look that’s pretty similar to most other recent Moto devices. The Moto X4 is also IP68 water and dust resistant, which is actually better than the Moto Z2 series’s “splashproof” rating, as pointed out by The Verge.

The Moto X4 doesn’t include Moto Mod support like the Moto Z lineup. It’s more of a mid-range device that comes with some features that users would find in some premium handsets.

The Moto X4 is powered by Qualcomm’s Snapdragon 630 processor with 3GB of RAM and 32GB of expandable storage, accoridng to GSM Arena. The microSD card slot is located alongside the SIM tray, which can be popped out from the top edge of the device. It’s also packing a decent 3,000mAh battery which also supports 15W fast charging through its USB Type-C port.

The highlight of the device is its dual rear-facing cameras. This is the first device in the Moto X series to feature this type of camera setup. The Moto X4 comes with one 12-megapixel sensor with an f/2.0 aperture lens with Dual Pixel autofocus, and one 8-megapixel sensor with a 120-degree ultra-wide angle f/2.2 aperture lens. Motorola says that this dual-camera setup will allow users to add depth effect on images, as well as add selective focus and color. As for video, the Moto X4’s cameras can record 4K videos.

Up front, the device packs a 16-megapixel camera that feature an “adaptive low-light mode,” which lets users take better selfies even in low lighting conditions. The only drawback with using that feature is that photos will be taken at a lower resolution of 4MP. If that isn’t enough, the front-facing shooter also comes with its own LED flash. Users can also capture panoramic selfies with the 16MP front camera.

Another thing that sets the Moto X4 apart from its predecessors is that it comes integrated with Amazon’s Alexa voice assistant. Alexa first appeared on smartphones with the HTC U11, and grants users access to all of Alexa’s skills from the Echo, like shopping from Amazon with just voice commands.

Since this is an Android Nougat phone, users will still have access to the Google Assistant. Alexa for the Moto X4 will only be available in the U.S., U.K. and Germany. Motorola also says that it plans to bring Alexa to more of its future handset.

Lastly, the Moto X4 also supports up to four Bluetooth audio device connection at once. The only catch here is that this unique Bluetooth audio feature will only work if the user's Moto X4 is connected to a wi-fi network that isn't 2.4 GHz, accoridng to Phone Arena. This can be a major issue since 2.4 GHz wi-fi is the most widely used standard. Users will have to configure their home router to use 5 GHz wi-fi instead.

The Moto X4 will be available worldwide sometime later this fall, and will cost €399 in Europe. Motorola hasn’t given an official U.S. price for the Moto X4 just yet, but the European price roughly translates to around US$475.
