camera Flash is greyed

[Manish2013]

Hi,
I had run the diagnostic tool and flash works as expected. However in camera mode it shows flash icon in grey. See screenshot pls suggest how to bring it back

Thats odd

Settings > apps > all > camera > clear cache/data > restart your phone and try again

If that doesn't work then repair your phone with 

Update Service (SUS)

PC Companion (PCC)

Bridge (for Mac)

If you select HDR mode then flash is greyed because it is then auto controled. I have written this in another post also.
