This is the best ever smartphone from Lenovo ever. Its is just like its predecessor k3 note with 5.5 inch display but it has a 3gb ram which takes the load and Give a smooth experience .
Till now I dont think there is a problem with The phone if you want to use it for normal usage . N in my view the add on is waste of money which Lenovo to magnify the videos it can put pressure on your eyes best part is this is having front speakers .
Which makes the sound clearly audioble if the phone is on bed unlike the galaxy I Which back speakers the sound is very low
