IPhone 4 antenna which can interrupt the call
Although it’s common in the Apple iPhone about “splitting hairs” things, the ubiquitous iPhone 4 has really met a little problem this time. At the beginning sale, many users took a collective action on iPhone 4 signal reception problems. Then, Apple‘s official came forward to clarify that it’s not the design defects of antenna, it’s caused by the formula errors when calculating the signal format, which can be avoided through the optimization of the software upgrade.
But as more and more users tested it, the antenna problems of iPhone 4 cell phones were finally revealed. An authority agency came from the United States, who released a report specifically for consumer, published the test report of antenna issue on iPhone 4 recently. They can be blocked in a radio outside the laboratory which launched a simulated base station signals the instrument directly test on the iPhone 4. The purpose is to provide controlled and stable signal strength and to control the experimental variables above the body of the antenna. The result is when the finger touches the joints of the lower left corner, the signal strength soon weakened, range up to 20dB, according to their statement, the decline enough to interrupt the call-Wholesale cell phones.
Be pointed out, the same of the experimental results found in three iPhone 4 mobile cell phones. We can see that it’s really the problem of the design of the antenna, not the calculate format error claimed by Apple at the beginning time…… For keeping the fairness and consistency, Consumer Reports also had the same test on iPhone 3GS and Palm Pre. But the signal weakened condition as same as iPhone 4 did not appear.
For the weak of the signal problem, the majority of consumers do not have to worry too much about it. Consumer Reports recommends that users can use the protection cover, such as Apple‘s official launch of the Bumpers protective cover. If you do not want to spend the money wasted if (Bumpers set the domestic price of 480 yuan to protect the ocean!), You can live with insulating tape affixed the bottom left of the joint area, but looks a bit ugly uh. Apple has not worked out the issue for the iPhone 4 antenna maintenance policies and remedial measures, it will be affect the sale of iphone 4 certainly on some extent, but I think Steve Jobs will soon solve this embarrassing flaw.
