As we reported the other day, several iPhone 4 owners have reported a yellow or brown discoloration on the device’s screen.
Well, there may be good news for these concerned customers. A forum post at AppleInsider, is claiming that the issue should resolve itself soon as the adhesive used to secure the glass to the LED screen dries.
Apple is using a bonding agent called Organofunctional Silane Z-6011 to bond the layers of glass. Apparently, Apple (or more likely Foxconn) is shipping these products so quickly that the evaporation process is not complete. However, after one or two days of use, especially with the screen on, will complete the evaporation process and the yellow “blotches” will disappear.
How do I know? I was involved in pitching Z-6011 to Apple.
Yes, I know, this could be any clown with a keyboard, claiming to be an “expert”, but this forum post does gain considerable credibility when coupled with reports that the discoloration is disappearing for some users as time wears on.
I had major yellow spots on the bottom corners of the iPhone 4 this morning when I received it (as shown in the other thread) and as of right now they have COMPLETELY faded away. I have no idea what caused this but it happened. So keep an eye on it over the next day or so if you have the issue. . . It just seemed like the more I used the phone today the more it faded. It’s really odd but I’ll take it.
In the meantime, other reports are claiming that customers calling Apple Support about the problem are receiving conflicting advice. Some are being told that it’s an adhesive issue and it will clear itself up, while others are being told to bring their device to a local Apple retail store to have it replaced.
My advice: Wait about a week. If the discoloration isn’t gone by then, notify Apple Support see what steps they tell you to take from there.
