I bought this phone 3 months back, and still trying to figure out what all this phone can do. The user manual provides very limited information. This phone comes with car holder, but the holder does not stay sticked to the windsheild. It keeps falling off, better forget that there is one. Touch sensitivity is very good, however, at time, the call may get disconnected with touch of user’s ear itself. One needs to get used to it. Its a sophisticated device, and requires careful handling. Battery back up really sucks up. With normal usage of 1-2 hrs. of talk time on daily basis, the battery requires charging daily. In fact, battery back up was the primary reason for me to change the phone, and that is the biggest challenge with this phone. There are some user interface issues with the menu and operating system as well.
