I'm convinced that all the iPhones are yellow on the bottom

Mine's black on the bottom. Just like the back, top and sides...

I assume you mean the screen? Mine doesn't look yellow at all.

 

mine's not

 

On my first one it was still so slight that I only noticed it after I read about the problem here. I think all the iPhones have a tiny backlight difference between the bottom half and top half because of the backlight technology.

Edit; to respond to the above poster, I have a 925 and can still notice it slightly. Actually, from what I've read, 924s are pretty on the money. However, if you're really looking fir it, I think you can see it on any model... Or at least fool your brain into thinking you do

 

If it takes effort to find it, why worry about it? I never, and I literally mean never, have my brightness anywhere above 50%. It's just not necessary unless you want to admire how vivid the screen can get. I haven't done that since I bought my 1st gen back in February of last year.

 

where do you find this?

 

Nope

Sorry mine passes with flying colors!

 

Mine's a 924, and it certainly is warmer than my 1st Gen's screen, but it's even all throughout. The only place that I start thinking it looks yellow is in the Settings app. If I hadn't even known about these threads about the yellowish screen, I would have never even noticed. And even now, it doesn't bother me.

 

mine is week 25 and no yellowing.

 

where do you see the 9xx??

 

turn white on black on (its under accessibility) and see if its still yellow. Mine 925 and its fine.

Ive notice everyone that has a 925 seems to be fine.

 

Where are you guys finding the model??

 

First part of the serial number: example 88925 = 2009, week 25. Digits 3-5.

Opps, btw mine is fine and a week 25 just for the record keepers...

I have a 923 and no issues...

 

Mines week 21 3GS..no problems.

 

I have a 925 and guess I should feel fortunate. No yellow anywhere.

 

The one i looked at on display in the store actually seemed to have a screen like the 3g's, cool and gorgeous. It was a 16GB black.

I've had 2 white 32's now that both have it... so i dunno...

It's terrible.

 

21 here and no issues as of yet

 

On my second 925 with yellow bottom

 

923 here. I don't notice any yellow tinge. My 3GS is warmer than my friend's 2G, but cooler(?) than my old 3G. Perfect temp screen I guess. (for me at least)

EDIT: And yes, I did go to settings and turn my brightness all the way. I also then opened my flashlight app to have an all white screen to compare. No yellow tinge at the bottom.

 

This defect was explained to me as follows:

The light source for the screeen must be on the top. Therefore because this light must travel the whole length if the screen, but doesn't quite make it, we see yellowing.
