Hi, all iwas using this mobile last 6 month s .So I will the what are the problems and features of this Letv 1s eco.Letv 1s eco is an china mobile by the company Letv .Letv sound reciption not good at all the time .There is some disturbance in sound quality .Letv 1s Eco is an eco friendly mobile which does not harm the nature . It is safe to use.Style and Design of the Letv 1s eco was some what good use or handle .It looks very stylish but weak in body design .Other feartures of this mobile is of fast finger scan sencor but does’nt work at all the time.Look and feeling Letv 1s eco was very hot it become using continuoesly .Looking the mobile phone was beatiful. But damages easyly.Value of money of the mobile was fair to its feature .But the is no expandeble memory to the mobile.So it was the negative point to mobile for not buying it.
