Dual Led flash not working topic

Hi everyone,

A friend bought a g3 today with lollipop version, and we just found out that the flash is not working.

We tried to install a torch application and a diagnostic app. But the dual Led don't turn on.

I don't think that flashing the phone will change anything, I'm afraid that it can be hardware.

Do you think that the dual Led can be replaced?

Thank you for reading , we really need your help...
