My Yu Yureka phone went dead (that is, the screen was blank) and was returned by Micromax after one month after sending it for repairing. I now find that the camera and flash have stopped working and all attempts to install an app failed. How do I get the camera and flash working again?
Android Version - Cyanogen OS 11 (based on Android 4.4.4 KitKat)
