I bought my Lenovo vibe k4 note 11 months before and from the day I bought it, I was facing a heating problem on the mobile. If I want to work half an hour then also the phone heats up and in one hour it becomes very hot to handle also.
All the other features provided by the company are very good like Dolby Atmos, fingerprint scanner, 13mp rear and 5mp front camera, and many more features are great to use.
But sometimes the phones does not respond to Twitter application and also the wallpaper setting is disabled to open and if anyone has a budget of 12000, then there are many more companies to go for because of these problems in the k4 note.
