There are a few Moto apps. The
"Alert" app offers a quick means to reach contacts in case of emergency. The "Moto" app offers the
"Actions",
Display and
Voice capabilities that a lot of people like very much (personally, I'd rather just have a notification LED -- which btw this phone does not have). And there's a Connect app that can associate the phone with other Motorola accessories (like the 360 smartwatch).
The
camera is, as is usual, OEM specific. The
Google Camera app is deemed by the Play Store to be incompatible with this phone.
Most else is pretty close to stock.
This model doesn't yet have Nougat. Someone posted
a 7.1.1 result for the X Style to GFXBench which has a number of users from India all excited, but there's no firm date or announcement of Nougat for the model. Mine runs the stock Marshmallow firmware.
