Lenovo vibe k4 note seems appealing in terms of price and specifications but let me tell this is not a value for money mobile and may prove to be a waste of your hard earned money.
The phone comes with 5.5 1080* 1920 px resolution, 13MP rear and 5MP f/2.2 front camera, 3300 mAh Li-Po non-removable battery.
After using this for around 12 months, that is when the warrenty expires, I experienced some problems with the phone.
The screen started developing yellow marks from the inside at the boundry, I approached the service center and they are demanding Rs4500+ for replacing the screen.
Also, suddenly the touch stopped working at some spots after a few days, which again need screen replacement.
Also battery backup reduced after a certain period of time.
Some disadvantages of buying this phone.
Non-removable battery
Dedicated memory slot not present, instead a hybrid slot is present.
3300mAh Battery seems great but is not good.
The lenovo moto service is as bad as this phone.
Overall, after using for almost an year I found this phone to be a waste of money, and recommend you not to buy this phone instead go for other latest phones.
