After much market research and taking feedback from my friends who own this phone, I bought S3 for 23K. This is the second Android phone I have used after disappointing Sony W8.
1) Speed: it has 1Gb RAM, cant handle many applications
2) Internal Memory: You can enjoy as many as Android applications because of usable 9 gb internal memory.
3) Camera Clarity: 8 MP camera captures beautiful pics
4) Video recording: it says full HD recording, but doesn’t seems so.
5) Best features: voice commands, S beam, Auto screen brightness adjustment.
6) Battery Life: sxxxx. hardly lasts for 5 hours.
7) Screen size: with 4.8" screen size you can handle this phone one handed and its very comfortable than 5" and above phones.
8) Back cover quality is relatively very poor. it looks like cheap plastic cover. Anyways you can change it with the best one you like.
Dont burn your pocket. you will get better phones than this.
