THIS PHONE WAS ONE OF THE VERY FIRST LAUNCHED BT VIVO INITIALLY IN INDIA BEFORE MOVING ON TO THEIR CURRENT V SERIES.I DON’T KNOW MUCH ABOUT THIS PHONE’S SUCCESS BUT THINGS HAD WORKED OUT GREAT FOR ME.I SUPPORTED A BIG SCREEN SOMETHING WHICH IS A MUST FOR ME AND A GOOD RESOLUTION SO THAT THE OUTPUT OF THE DISPLAY WAS GOOD .THE SOUND OUTPUT WAS ALSO VERY GOOD AND I PERSONALLY LIKED IT.THE BATTERY WAS NOT THAT EFFECTIVE FOR ME BUT YES INITIALLY IT GAVE ME BACKUP UPTO ONE DAY.THE REAR AND BACK CAMERA WORKED WELL AND GOOD MULTITASKING WAS POSSIBLE.
