Hi, you can try resetting the camera app by long press it and tap info then scroll to storage and clear data,cache and then force stop it . If that doesn't work try uninstall the update in same place where you did cache and date clearThanks. i tried in safe mode and it's still greyed out.
it IS working on video mode so i'll be surprised if it's hardware problem.
For months, the flash button is grey out. (not in video mode)
i try change all the settings but nothing helped.
any ideas?
thanks!
