Possible explanation, fix for iPhone 4 yellow splotches?

Okay, this is thin, but seeing how some of team TiPb are experiencing the dreaded yellow splotches on their iPhone 4, we're clinging to threads here -- forum threads in this case from Apple Insider:

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.

Jeremy wonders how this explains perfectly straight yellow lines, so who knows, but it's something to consider. If you have the splotches, chances are Apple won't have replacement units for you in the next few days anyway, so keep on using it and let us know if you see an improvement...

  • Sounds to me like it's an excuse to kill some time so they can get more stock to replace them. Actual sales first, replacements second.
  • Maybe there will be good deals on refub iPhone 4's in the near future!
  • Those who adopted the Palm Pre early on will remember that many, many units had this exact same issue. And no, it does not go away with time. Good luck getting it replaced, most of us just had to eventually get used to it.
  • This is fact, at least in my case. After only hours of use, the yellow splotches went away. I was amazed/relieved.
  • apple isnt palm. we have decent customer service so no one will have to get sed to it. I have my iPhone 4! no yellow!
  • I just got my iPhone 4 32gb - no yellow splotches at all. Were they noticeable immediately or did they appear after time?
  • Mine has the yellow blobs, especially shows up on white backgrounds like in messages. Hopefully with a couple of days use it'll go, otherwise it's a genius appointment for me.
  • I noticed a splotch on mine when it was mailed yesterday. It has slowly started to go away over the day+ of use. This has been confirmed by 2 sets of eyes that saw the phone when it was delivered, and this morning.
  • I set an appointment for first thing Saturday morning. I'll have to see how it looks when I wake up Saturday.
  • I don't have the yellow splotch problem, my new phone keeps losing the sim ( sim not found)...Apple Store in Jacksonville FL says Saturday for exchange phones, I have made reservations for the local Genius Bar.
  • I'd say it would have to be an issue regarding the covering of the screen rather thanthe screen itself. If it were the display, it would be pixels rather than areas that are affected. Given the people who claim that the problems have gone over time, I'd say this isn't a huge problem. I was beginning to worry :)
  • I returned mine this morning in Bethesda, MD with no hassle.
  • Is palm still in business? Oh yea they aren't.
  • Lol did I get a special phone or something? I've been reading on giz and other sites. That people are seeing yellow spots and when you hold the phone a certain way the signals drop. Why I'm I not having these problems? I'm actually getting a better signal in my home and outside with the new phone. What gives?????
  • I wonder if the people who are reporting their spots disappearing will continue to see that that is the case over the course of several days. With the Pre, the yellow splotches would disappear at times, but then would later reappear. Heat often made them more noticeable.
    Note, I'm not saying that this is the same issue, just curious if there are some correlations between the two. For people who have the spots, I'd be curious to see if the spots returned if they left their phone in a hot car for a few minutes.
  • Yellow lines and spots on mine right out of the box yesterday. Definitely not going away a day later and I'd say they're getting worse with the more I use the phone. Heat seems to really make them noticeable.
  • Hi,
    I really wondering as using the side of the phone will increase radiation/cancer to the user?
  • Didn't the EXACT same thing happen with the second generation ipod touch?
  • I have pretty dark yellow spots on mine. I'm ok with it though as I wanted white - this gives me a PERFECT chance to use the new phone then trade it in for a new color in a few weeks time. Bonus for me... unless they away.
  • This is what you get for paying for something sight unseen. This is a stupid idea no matter the company, no matter the reputation. I'm sure most of the iPhone 4's have no problems. But if any of you had waited and checked one out at the store (without a giant line behind you). No one would have sold you a phone with a big yellow spot, let alone you allowing them too. Everyone has to have the iPhone on release day though. Enjoy your factory defect.
  • I just gor my iPhone 3 today, I have the yellow blob on the button right of my screen, I hope it disappears!
  • Oops iPhone 4
  • there may be 2 sets of yellow displays... One that will go away with time as the article suggests.. For the reason of the gel needing to evaporate..
    and one that's caused by the phone overheating as the pre

  • UPDATE - Mine has faded
  • I pre-ordered mine. Got it this morning and had the yellow line right across the screen. Took it into the apple store and got it replaced without having to line up. It never faded though.
  • My yellow spots and lines went away with time so I'm happy
  • Mine was there big too but it has faded away. Oh yeah!
  • I got mine via FedEx on Wednesday morning. I even came home from work to get it, activate it, and synch it. When I unboxed it, I had a yellow splotch on the upper right hand corner. I was going to keep the phone for the day and wait until the launch date to take it into a Genius Bar... but lo and behold, before the work day even ended, the yellow splotch was gone. I guess I'm one of the fortunate ones.
  • UPDATE 2 - Mine finally disappeared!
  • I bought my iphone 4 with 32gb on the 24th of June. When I started to use the yellow blotches were there. However, they are not going away. Inf fact they become stronger when I use it during a bit of time. I called Apple support yesterday (27/06) and they politely explained that their engineers are researching the reason for that and I should wait a little bit more before swap my iphone. I'll wait until thurday, otherwise I'll go directly to apple store and try to swap it since their have a very low amount of units. I love the phone, but it is very disapointing mainly because it is such an expensive product.
