Good phone overall.
I bought this phone last September and was very happy with it when I first got it. I felt that the MP3's were loud enough while lacking in sound quality a bit. This phone does not have enough built in memory, and it has no expansion slot. The screen is a work of art being very bright and very clear. The flash on this phone is absurdly bright. Very handy at night, especially to blind people. Bluetooth leaves a lot to be desired. I have used the Motorola H700 and HS850 headsets as well as other various Jabra and Samsung headsets and voice clarity and quality is mediocre at best. This phone's outer nano coating is very nice and people notice it when the phone is taken out. Good conversation starter. Battery life is good.
SGH-E640 bluetoth issue
I have recently bought this phone and tested on my bluetooth motorola H850 headset, its works without fail. But when the phone is in standby mode for about 30 mins, and when I receive a call and try to answer on my bluetooth, it cannot link to my phone.
Overall the phone is good, and is having clear reception. But too bad the bluetooth is not I expected.
The set does not comes with data kit, so until now I did not load any MP3 into my phone.
