I bought this lenovo k6 note mobile recently.. Its my first lenovo phone.. And am so disappointed by this ptoduct.
Touch pad is not working.. Back button, home button etc.. While using the phone the dial pad also getting hang some times. And its very annoying that phone is automatically doing actions by itself while am using phone.. Its very annoying and am disappointed with this phone.. This phone is really waste of money.. I just wanna replace this product.. I hope u will understand and solve this problem as soon as possible.
