Same dilemma here. My Nokia c7 digitiseris damaged . Nokia does not service old phones and aftermarket digitiser is available but I'm sure its not gorilla glass , so just left the phone as it is . I have the liberty to do this as mine is a very old phone and I have already upgraded . in your case the quality of the glass and LCD is important as you touch the screen and use it all day , so do not compromise on quality, get it done at the service center . Else buy a new moto e 2015 for a slightly higher price than your screen replacement cost and let the moto g rest in your drawer as it is .
