I have a Lumia 640. After an extensive tour in South India, where I captured many excellent pictures and videos on this camera, I tried to charge my phone in a taxi. The phone went dead. There is no display and it does not work. It just vibrates once, when I press the power button. I used a different battery from another Nokia. Still the result is same. I took it to the repair shop in Hyderabad. They told that it is a hardware issue and that they cannot retrieve the data. Can anyone suggest a way to retrieve the data or suggest a Nokia repair shop where they can repair the hardware and takeout the data? Or is there any simpler solution? Request your help. thanks.
