I purchased Samsung Galaxy S3 smartphone a week after it was launched in India. I am extremely happy with the purchase. I paid around Rs. 37K for this phone at Croma store. I like the pebble blue colour. It has a 4.8 inch HD screen. The photos that you would look at from picasaweb, Facebook and any such programs are awesome. The clarity and sharpness of the pictures are amazing.
The one thing you have to be aware of is that this phone uses the micro SIM instead of the regular SIM. I had to run to the nearest Airtel shop to get a new microsim to fit into this phone. Note that all providers may not have a microsim readily available and you may have to wait for a few days to get it. This phone runs the apps very fast. If you use a 3G SIM, the downloads are pretty fast as well. I have been using this with the WIFI connection and happy with the speed. The Samsung store has practically an app for everything that you can think of. A lot of these apps are free but for some you will have to pay. I liked the feature where you can add a shortcut on the home screen for speed dialling or SMS. You just have to touch this icon and it will dial or SMS the number.
The 8 MP camera does a good job in taking sharp pictures. Overall worth the money spent.
