I am still wondering if there is in fact some hardware issues. I have yet to know for sure if there is supposed to be minor clicking while it focuses? Some say no, but I thought the same thing until I went in a VERY quiet environment and then took some picts. Definite clicking when it attempts to focus.
I think that is normal. Everyone has the clicking which is the lens moving. I have played with over 12 phones, owned 3 different ones, and they all have that clicking.
