I have bought this mobile 1 month ago and this is very intresting mobile as it dieged from other samsung mobile phonea and the most advanced feature of this mobile is its camera and the focis of its camera.it is incradible and have capture at the spot moment.while I tryid to capture a picture of a moving train thrn I found thatt I even can see the people doing their work in the high speed train.its impossible to capture such a thing in very high speed.another function I like was its battery backup.most of the samsung mobile have a problem of short battery backup but this one not.
