YouTube The video above shows my experience with the iPhone 4. At first, I was very angry at being able to drop calls on command by putting my finger over the left side seam, sometimes even only halfway. However, I gave Apple the benefit of the doubt because even flaws in past products that were claimed to be hardware defects (iMac screen flickering) were eventually fixed. Nevertheless, I do still have doubts. Upon testing a co-workers phone today at work, I could not for the life of me get his signal to drop below five bars. This lead me to the video above, where I held my phone as I normally do. It dropped to 'Searching'. Then, keeping the phone in the same position, I walked over to my windows, which is about 30-40 feet. The signal popped right back up to four bars and I could not get the signal to drop. The reason this is significant is two-fold: 1. This is the first video I've found documenting the fluctuation in signal using the 'death grip' in two locations with the same phone. Signal strength 100% impacts the perception of the flaw, correlating nicely with Anandtech's findings and this video demonstrates why some people claim they don't have the issue. 2. This means that perhaps there is some credit to be given to Apple when they say they need to adjust the number of bars being shown. If I'm really getting one bar farther from my windows, it would make sense if I drop the call when holding it. Regardless of what the final issue(s) turn out to be, I'm hopeful Apple will fix them. And if there is a hardware recall, I will be first in line for a replacement.
