This is an amazing smartphone in this price point but has many cons such are: -
1.Unnecessary apps which comes pre-installed which user cannot uninstall.
2.It runs on Android Lollipop where Marshmallow update is not there.
3.Another disadvantage of Lenovo Vibe K5 Plus is the absence of Fast Charging which may be dissapointing for users.
4.The 2750 mAh battery capacity is a bit on lower side for full HD display as it decreases faster.
5.There is no Fingerprint Sensor in this phone where other companies are providing fingerprint such as coolpad and Letv which leads to dissapointment to the user.
