I am using Lenovo vibe K5 from more than six months now.
Initially it worked fine but now I am totally unsatisfied with this phone.
Lets talk about its pros first. The build quality and look is great and stylish.
Sound speakers are super awesome.No need of external speakers to enhance sound.
Camera Quality of both rear and secondary is supergood.
Its 16gb memory is also a good storage solution.
Now lets come to the cons. It has 2gb ram in which about 50% is always free, bt still my phone lags heavily. I need to restart at times. The security lock of the phone stops working mostly. After using this phone for 2-3 months I faced a very wierd issue that its Led light blinks all the time continuosly. I even dnt have any option to switch it off permanently.
The biggest issue is its heating problem. If u work or surf internet for few minutes it starts heating. It heats so much that u can't hold ur phone at your ears to talk.I plug in my earphone if I have to talk more than 3-4 minutes.
If one is planning to buy this phone I would suggest to reconsider it.
