Lenovo k3 is based on a 2GB ram, with a 16GB internal memory.which can be expanded through micro-SD card. its sound quality increases when you click ON the Dolby sound option which gives a better sound quality.the phone is said to be user friendly and also its look is smart and handy.but in my hand it keeps on hanging.and suddenly a blank screen appears and sometimes results to switch off.but its both the front& rear cameras are great worker.it comes up with a good flash quality, its design is good.but it sometimes heat up and when I tried to play grand theft auto in the phone it goes again to its worst hanging mode, that means its not an gaming phone.its battery is good.but rather than this its good for normal camera or multimedia use.the phone can not be said as a value for money, because their are even better phones are availabe in the market with higher specifications or features.
