The Lenovo Vibe K5 note phone with 4GB Ram and inbuilt 64GB ROM performs very well. The phone(for a Iphone user like me) proved to be very user friendly. The style and design is very good and feels robust. The Fingerprint sensor to unlock the phone is the fastest among all phones seen by me. All apps and games run without any concerns due to the solid processor of the phone. Though the call volume during conversation is a bit low, the music sound quality is superb due to the Dolby Atmos feature. The sound is rich is bass and also clear when equalizer is changed. Overall good quality phone and value for money.
