Samsung Galaxy J2, my brother bought this mobile in the month of Feb 2016 for ?9, 300. J2 got all the features which a basic smartphone should have.
The camera quality is good with 5MP rear but not excellent. The audio quality and the screen resolution is good.j2 got dual sim slots and it supports 4G. I know there are many other mobiles are available at this range but it matters the brand and the service.
