Dear Lenovo,

I remained to be a very happy user of your products, however, purchase of Lenovo Vibe K5 note mobile phone was other way round. The phone is not even 6 months old and I bought it from Flipkart. I found every feature on the phone is very promising till when I started getting the problem in its unusual hangs many times a day and sometimes even 2-3 times in a hour. This is very discouraging when I trusted the brand till so many years.
I don't want any surgery on my phone and give it back to me, rather it is more likely a software problem. Therefore, I am asking you for a replacement of the phone at its earliest.
