Lenovo viber k4 note is one of the best phone in his class. k4 have grate feature. I purchase this phone because of its theatre max feature. this feature is one of the best feature in this phone. now we can watch every thing in this mobile in virtual reality. lenovo also giving VR box with them. vr quality is very good.
the plus point of this phone is hd display of the phone and processor speed. speed of mobile of loading of app is very good. k4 have no heating issue.camera of phone is also good.
negtive point is that it doesn’t have quick charger. it take too much time to charge. capicity of battery is normal not best.
you can buy this phone for theatre max.
