I dont have moto g mobile but my friend have it and I was seen the great phone in affordable rate.
It is 5 inch HD screen mobile. It has preinstalled android browser.
It has Hall effect sensor, accelerometer etc sensors feature.
It has Cornig Gorilla Glass 3.
Its battery backup is also good . 1 gb RAM for this mobile less but better than other brands.
16 GB internal memory available and expandable upto 32 GB.
We dont need to expand because it has 16 GB inbuild and it is much more to install app.
Processor is also good i.e. 1.2 GHz qualcomm snapdragon processor.
Android kitkat version 4.4.4 .
These are the great feature and great mobile also by motorola.
