Significant Difference in iPhone Models

First of all ... why in the world would you do this anywyas ?

Have you tried changing the 'brightness' in the settings???????

I had this problem on a brand new replacement iphone. Where i really noticed it was watching a movie. Anything dark would not show any detail.

I returned it and got another new phone.

There are two different screens made for the iPhone. One ***** and the other doesn't. Check out this article from Yahoo Finance (bracketed) it may help you determine which one you have.

[If you've been toying with the idea of buying an iPhone, here's something you want to read. Computerworld recently came across complaints that some iPhone touchscreens are better than others. Several iPhone users have posted images of side-by-side phone comparisons that show screens on iPhones with Panel ID 7 are darker, fuzzier, and display a visible grid of dots across the screen. Those who have noticed a significant difference in their iPhone's screen quality have taken their complaints to Apple's support forums, and some even went as far as exchanging their iPhone.

One way to find your iPhone's screen information is by tapping in 3001#12345# on the phone keypad and hitting the Call button, which puts it into Field Test Mode where you'll find the "LCD panel ID" number. Phones with a panel IDs that start with 7 are the ones people are complaining about, while the those that begin with a 5 are brighter, sharper, and don't show a grid pattern. Computerworld says users have several theories about the faulty touchscreens, such as registration problems between the touchscreen and overlay to differences between screen suppliers. Toshiba, Sharp, Epson, and Matsushita Display Technology all supply Apple with screens for the iPhone, according to reports, so who knows which company is supplying the dimmer screen.

I, for one, know that if I paid over $600 to be the first with an iPhone, I'd want complete satisfaction, and that would include a touchscreen that's sharper and brighter. How about you? Has anyone else noticed this problem?]

ok so i tryed the whole 3001#12345# thing it didn't work, anyone esle have another way of knowning how to find out which model one has?

thanks for any info.

You need to precede the number string with a * and place another * at the end of the string. That will allow you to enter the field test mode...

Good luck

thank you "kjlake" it worked perfect, as i see i'm one of the unlucky ones to have an iphone with numbers starting with "7". . .

My LCD also starts with a "7" but I think that the LCD is sharp, the brightness varies based on the level that I put in settings and I am happy.

It may be that some "7" LCDs are bad but I have also been of the opinion after 60+ days of my personal hands on experience and reading these threads that there are some QC issues and it may be that not all LCD beginning with a 7 are in fact bad.



mikeab 🙂

I too have a number that starts with "7" and i find my screen to be clear and sharp.

So, it must be something else to it other that the number thing.

I tried to input the numbers. When I go to hit the call button I get "Error performing request No Network Service"

Not that it should matter but I have full bars.

you have to add the * before and after the string. I did what you did too and saw somewhere on this string to add the asterisk before and after and it worked.

I just did that and it tells me my LCD version is a "5755xxx" number. Just bought it 10 days ago...I kind of figured since one of the posters had his phone for 60 days and had a "7" LCD, mine would be higher
