The display is one of the big differences between the three devices. The C3 offers just an okay display so if you want something better, the M3 and X3 are the ones that have that. The most noticeable difference between the three has to be on the camera department. The C3 has a 13MP main camera while the M3 has a 48MP and the X3 has a 64MP. That type of camera for the C3 is okay since the phone has a price that’s barely over $100. It doesn’t really get much better than that for a phone with that kind of price. The M3 does offer major improvements for less than $30 more.
