my device is c6502 Front some days i am having problems with my front camera . It shows pink lines or screen on camera and then crashes. By checking varoious options it seems that it only occurs when mobile data is enabled . When mobile data is disabled then there is no camera problem . I have sent the device to service center two times but they were not able to find the cause . They have replaces my set but the second device also have the same problem . Do anyonw here facing such problem or have any solutions to that .
