Samsung Guru Music 2 SM-B310E commonly known as Samsung Guru 2. It is the next version of Samsung Guru Music.
It has some similarities with guru music .
And it also has some difference from guru music. You can say it is a upgraded version.
Some good features: It has voice recording feature(but up to 1 hour). Screen size of guru music 2 is bigger then guru music. It has radio. You cat set wallpaper from your sd card(its cool, you can customise your home screen).
Some bad features: It did not have Bluetooth. And it did not have internet. This are very irritating for me so I did not like this phone.
