Apparently, there's also an Android One version of the Moto X4 coming, according to this tweet by prolific leakster Evan Blass:

Android One means that the phone will have completely stock Android with none of Motorola's enhancements, but it should also mean the phone will get Android updates just as soon as Google's own phones.
(Also see: Moto X5 rumours.)
When is the Moto X4 release date?
On sale: end of September (Europe), late 2017 (US)
You'll be able to get your hands on a Moto X4 in just a few weeks if you're in the UK or Europe and later in the autumn for those in the US.
For the Android One version, no release date has been confirmed, but according to rumours, it will be the first Android One phone to go on sale in the US. Previously, such phones have been sold in third-world markets due to their low prices.
How much does the Moto X4 cost?
In the UK it's £349 if you buy it SIM-free. It's available from Motorola's website and Carphone Warehouse. There's no US pricing at the moment, and certainly no information on how much the Android One version will cost.
The newcomer is available in Sterling Blue and Super Black.
What are the Moto X4 features?
Prior to the phone's launch many of its specs were leaked (and images), and it turns out they were mostly correct.What we didn't know was that its frame is aluminium and its screen is covered by Gorilla Glass 4.
Here are the key specs:
- 5.2in full-HD screen with Gorilla Glass 4
- 148.35 x 73.4 x 7.99mm body (unconfirmed)
- 163g (unconfirmed)
- Snapdragon 630 processor
- Adreno 508 GPU
- Dual-lens SmartCam (8Mp + 12Mp)
- 16Mp selfie camera with front-facing flash
- Home button with built-in fingerprint scanner (also supports gestures)
- USB-C port + headphone jack
- IP68 dust- and waterproofing protection
- 3,000mAh battery with TurboPower charger (included)
There are three main features that make the Moto X4 stand out from similarly priced rivals: its waterproofing, dual cameras and Alexa (much like HTC's U11, a flagship that's much more expensive). With the latter, you'll be able to call on Amazon's assistant even if your phone is locked.
Rather than go down the Z2's route of a colour + monochrome sensor combo, the Moto X4 has two colour cameras. The main 12Mp camera has dual-pixel autofocus and an f/2.0 lens.
The secondary 8Mp camera has a wide-angle 120-degree f/2.2 lens.
The combination lets you achieve photos with depth effects, selective focus and colour.
Around the front is an even higher-resolution 16Mp camera which offers panoramic selfies and has a low-light mode which reduces resolution to 4Mp to offer better performance.
Going beyond this, Motorola has added the ability to recognise certain objects and landmarks when you point the camera at them, similar to Samsung's Bixby.
