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.
