K5 note 4 GB ram phone is awesome with dolby sound system. This andriod mobile is ease to use. Fast charging mode is also there with this your mobile will full charge in 60 minutes. Its 4000 mah battery is good and giving 2 days battery backup. This mobile is very slim soo it looks cool to me. Because of 4 gb ram mobile is working good. In 14499 this is the best buy. Because of lenovo its reliabil for me. I love my Lenovo vive K5 note.
