I bought this price from Snapdeal last June. In the very begining the phone worked properly. But about a month later I started facing lags. Phone used to frequently freeze.I bought this phone knowing it had a 4GB Internal memory and a 512 MB RAM. But the reality is u get only 2.5 GB of it to save your own apps. There is no such feature to save apps in the SD Card.
On top of that, this idiotic handset multiplies all the files in your handset as duplicates whenever u plug the phone to PC on the Mass Storage mode. This was the most frustrating experience off mine. Useless apps such as Sony Jive, Sony Select eat half of your memory. And RAM is another factor in this world of frustrating experience. No app provides smooth interaction.
Hence, this is a complete nonsense and no one should buy this useless device worth Rs.3500.
