Evan Blass has published an official render of the Moto G Stylus (XT2043-4) confirming, indeed, that this will be the device's name and this isn't the Motorola Edge+ as speculated.
The render unveils only the front of the smartphone and its stylus. It is clearly visible that there's a punch-hole front camera in the top left corner.
If the date on the render is true, we might actually see the Moto G Stylus on market in April.
We expect it to be announced at the end of February at MWC 2020 along with the Moto G8 and the Moto G8 Power.
