Sir i bought my phone four months ago and my phone is not functioning properly from first month and i told about this problem to nokia centre firstly they told me that they will resolve my problem but after then they ignore my complaint. It stops working while i use it i told about this to nokia centre. Firstly they updated phones software but the problem is still not resolve and after then they told me that we will change the display. But after then they refuse my complaint by saying that your screen is damage but the screen is all good even a single damage is not on screen so please resolve this problem as soon as possible otherwise i have to go for consumer court
