I have a Samsung Galaxy S Duos (GT-S7562L).
The camera is good, but its flash is so strong that after the photo we have to wait for 1 or 2 minutes to our eyes be able to see all clearly - it is like to when you see the sun light directly.
So I would like to change flash brightness in some way: hardware or software.
The easier but ugliest hardware way is to use a semi-transparent sticker in front of lens.
Do you know any way to change flash brightness entering some hidden settings (common settings do not have that option) or using another settings app or camera app? The phone is not rooted, but I accept solutions in this way.
