I bought this phone few days ago.

Getting lag and hang sometimes while in the panel in changing home screen.
Auto connect GPRS after Wi-fi connection has disconnected; it makes a lost to user who is not subscribe to unlimited data plan.
Only internal memory is available for storing message.

But variety of home screens are giving users more features.
Exhausting energy pretty much/fast; for me or maybe other users are not occuring this issue.

It is still to consider very good as for im still a new user on smartphone, with this price is affordable for major users.
