I was bought this phone Sony Xperia C in last year in the month of September and since today this phone was running very smoothly without any lags.The best thing of this phone is that its camera.It captures very good pictures during the daylight.With 1GB of ram this device is running smoothly.
Overall this is the best smartphone I had ever seen.This phone run very large games without any hangs.The sound clarity of this phone was really decent.
