I have used that sony Xperia smart phone more than two years age still I feel that was so good and super performance as compare to my J1 ace smart phone .
That phone speed was so good and battery bachup was very long time
Features was so good as comparing price
While the most important thing is the design and architecture of that slim little curve smart phone as spectacular looks .i loved that phone again I wish to use sony Xperia series phone .While in my experience sony Xperia economy range smart phone has so better than samsung .
