Confirmed: iPhone 4 Antenna Reception Issue Is Hardware Related

The story of antenna and reception issue has taken yet another turn. Testing engineers at Consumer Reports have revealed that the antenna and reception issue with iPhone 4 commonly referred to as “Death Grip” aren’t software related. This finding clearly denies Apple’s Claim of this issue being software related caused by an optical illusion due to faulty firmware. Consumer Reports comprehensively tested Apple iPhone 4 hardware by simulating carrier tower test and found all three testing units purchased from different locations, experiencing abrupt signal loss issue. The process also tested At & T signal strength perspective and found the carrier not responsible for the iPhone 4 reception fault. The test was also carried out with other smartphones like iPhone 3GS and none of them experienced the reception fault concluding that this might be an iPhone 4 design glitch.

According to Consumer Reports:

We reached this conclusion after testing all three of our iPhone 4s (purchased at three separate retailers in the New York area) in the controlled environment of CU’s radio frequency (RF) isolation chamber. In this room, which is impervious to outside radio signals, our test engineers connected the phones to our base-station emulator, a device that simulates carrier cell towers (see video: IPhone 4 Design Defect Confirmed). We also tested several other AT&T phones the same way, including the iPhone 3G S and the Palm Pre. None of those phones had the signal-loss problems of the iPhone 4.

Our findings call into question the recent claim by Apple that the iPhone 4’s signal-strength issues were largely an optical illusion caused by faulty software that “mistakenly displays 2 more bars than it should for a given signal strength.”

The tests also indicate that AT&T’s network might not be the primary suspect in the iPhone 4’s much-reported signal woes.

One solution to the Apple iPhone 4’s antenna
problem is to cover the lower left corner with tape.

We did, however, find an affordable solution for suffering iPhone 4 users: Cover the antenna gap with a piece of duct tape or another thick, non-conductive material. It may not be pretty, but it works. We also expect that using a case would remedy the problem. We’ll test a few cases this week and report back.

Here is the video direct from consumer reports that depicts their opinion on not recommending the iPhone 4 to the consumers:

Our exclusive source at Apple also confirms iOS 4.0.1 internal update doesn’t fix the iPhone 4 reception issue and the signal loss problem is still there.
