I used this phone for 3 months and I feeled this is worst phone of lenovo. I kept this phone very carefully never fallen this phon but suddenly the sensor buttons of this phone not worked .and the sound quality is also not good as like lenovo k4. it has only 4 gb ram and it does not matters.this phone is not very stylish and features are average.Not so very durable phone and I think this phone is totaly waste of money.
