iPhone 7 Plus Home Button Ring Discoloring

Just looks like my 6 which always looked like that. Just the way sapphire reflects light. Cause it's also like this on my 5s and mini 4 just looked

 

Looks normal to me.

 

Nothing wrong with your button. It will not match the surrounding screen. The reflection in your image is just the bevel around the button.

Your phone is normal

 

The home button to me is slightly more shiny than the screen. I think that's normal because it is different material. It looks normal to me.

 

Honestly, I can't see any discoloration from your picture. It's doesn't show much. Also, the home button has a protective sapphire layer, which acts as a protectant from scratches for Touch ID. I have never heard of discoloration with the home button before.

 

Nothing wrong with the color, negative discoloring. Enjoy your ip7, its really a great phone.

 

Only thing I could imagine discoloring would be the stainless steel ring around the sapphire button. If somehow the layer of black wore away, which I'm not sure is even possible without some serious abrasion. I assume the color is applied the same way as the space black stainless steel Apple Watch, which is very durable.

 

There is no stainless ring to corrode.

 

First of all, I never said corrode. And you are incorrect - there is a stainless steel ring around the Touch ID sensor. What do you think the metal ring is made of?
