I used the midnight blue leather case in 2 different times, and in both times, it turned almost black fairly quickly. I do not think it is due to dirty or oily hand etc. It appears that this is due to some friction with hand or cloth, and exposure to sun.
I don't think he's speaking about leather cases... Maybe he's referring to silicone.
Buy both and switch between them
Has anyone had any issues with the white cases turning yellow from hand oils like a lot of other white and clear cases?
I have the leather midnight blue. Looks great, no issues.
The only issue I had with the midnight blue leather case was that it started to turn black after a couple of months of usage. Others have experienced this too.
