This phone hangs many times in a weak and also lags while playing heavy games like asphalt 8 ect, dolby sound are not that clear in compairsion of other lenovo dolby sounds and the built in quality is not that good which should be, it dosen’t feels solid and also it feels ordinary phone while carring in hands, camera quality is average, sound quality dosen’t feels like dolby just because of single sound feature, battery durability is also average, overall this phone is not good at all in this price.
