Sometimes, even flagship devices have annoying quality problems. The Samsung Droid Charge had the fateful "blue screen of weird," and now rumor has it that the iPhone 4S is suffering from a similar (if slightly less severe) problem.
According to Apple's support forum, users of the iPhone 4S are finding the display to be "washed out" and unusually yellow, especially compared to the iPhone 4. Some of them blame the same glue hardening problem that was supposedly the cause of a similar problem on the iPhone 4, but others discredit the theory saying glue would not cause the screen to wash out, only turn yellow. Whatever the cause, it seems pretty clear that there is a problem with at least some 4S units.
Some people may be tempted to cite this issue as the reason Apple really isn't that much better or more reliable than the likes of Samsung and Verizon. However, no company can completely avoid quality problems in a few devices; what distinguishes them is their reaction. When similar problems surfaced in the past, Apple was quick to replace faulty units with new devices. In contrast, it is usually at least a little more difficult to get service on other devices. So, as long as the issue isn't too widespread and Apple maintains the same service and replacement policy as before, this shouldn't be too big of a deal.[PCMag]
