Samsung S3 and Galaxy Grand I9082 short comparison

It seems that Galaxy Grand is good option in 17-18 thousand. Has good features in comparison with S3 but still S3 is more powerful in processing and has more internal memory plus 2 more sensors than galaxy grand.

In short, summary:

If its feasible and possible for you in terms of budget then I’d suggest go for S3 J so at list for 2 years you don’t have to worry about new emerging technologies.
