Lenovo vibe X3 is a phone with very good features at a price of 19999.It is not a low price but for this phone it is suitable price. It is a phone with 32/64 gb internal and we also insert a SD card upto 128 gb. In market many phones are of 32 gb internal but they dont have feature of inserting SD card but it has this feature. It also has a latest android 5.1( lolipop) . It has a light weight of 175 gm. I recommend everyone to buy this phone.
