Lenovo K3 Note is a total wastage of money. I bought it just before 15 days. Battery is drainingvery fast. for this new phone also I am charging for daily twice . Hand set is becoming very heat if I am talking even for 5mins. Audio quality is sopoor that you can not listen voice in bus or at a rush area. You can use this mobile only for 30 sec calls. Audio quality is so poor dont even think to listen a music in this phone. I ve simply wasted my money and now no one is resolving the issue also.I would like to aware you that I purchased it from Flipkart and since the date of receiving it I am putting complains and they are not taking any action to replace it.
