Its a best selling phone made by Samsung, Its battery back up is amazing. Very pretty in looks in design. It also dual sim feature with memory card slot. This small phone have blue tooth & it also has usb cable facility. Sound quality is very nice. It is so easy to use its feature and its application. I think this phone is really value for money for me. I am using it since 1 year and I did not face any problem with it till now. Thank you so much SAMSUNG
