Lots of people have been wondering about the difference between the blackberry Q5 and the Q10. From the name, people seem to conclude that the Q5 is half of the Q10, but that is an error in judgement. The Blackberry Q5, a phone released months after the Q10 is more like an affordable version of the Q10, both run the latest OS from blackberry.
Aside from the memory, the camera and the fact that the Q10 battery is not removable, the other features are basically the same. Check the image below to see the major difference between the phones. In Nigeria, the Q10 is currently sold for N105,000 and the Q5 for N67,000.
