When the iPhone 4 was released in June 2010, it was not without this ratio becoming part of the glitches. The first reported bug was the iPhone 4's wireless 3G antenna. It is suspected of having a bad bet and a large amount of dropped calls. The following reported problem occurred with the iPhone 4 Proxy Sensor. Apple solved this problem at the software level, iOS 4.1.
Since iOS 4.1 has issued a number of questions about whether the update resolved the problem of the iPhone 4 proxy sensor at one and the same time. Based on my own experience I did not complain as this software update was published.
Some may be wondering, "What is a proxy sensor in the world and what function does it work for?" Without being overly concerned, every iPhone (including the original iPhone 2G, 3G, and 3GS models) has a ratio detector. This sensor emits infrared (IR) light that detects the presence of a solid object (such as a head or a hand) while making a call or listening to a voicemail. When you detect a solid object, it will turn off the iPhone LCD panel. This is a feature that you will probably never miss while it does not work.
The Proxy Sensor function actually has two different benefits. First of all, it does not bother the phone, accidentally press buttons or hang up callers with your face. Another advantage is that it maintains power consumption and improves the battery life of the phone during charging cycles.
As an Apple Certified Macintosh technician who alive supports and records Apple products, this is a question that can not be ignored. The reputation of my business has shown that you are finding a reliable and professional solution to this problem. Extensive research and testing has been carried out on this topic and I feel that I have made great progress in solving this annoying error.
For the past four years, when I've fixed iPhones, I have only recently experienced the widely documented and reported issues. Since iOS 4.1 released, I have not seen cases where the iPhone proxy sensor was faulty on the phone, which was not modified. When I say that "modified" is a phone that has been converted or replaced by the front glass and the LCD, and the original glass was damaged. I noticed that the occurrence occurred in multiple colors after a color conversion was performed.
As the iPhone 4 proxy sensor is located on the center frame of the iPhone and is not part of the front glass and the LCD assembly, I have never questioned the quality of the purchased parts. With this in mind, I started repairing everything before repair. I was sure that the phones worked well, before repairs or in color conversion. So far, I have not found anything that did not work well before repair. It turned out that the problem was caused by two factors.
first Unique sensitivity of each iPhones proxy sensor.
2. The probe sensor of the replacement glass is dark in color. It passes too much light.
I learned a lot of articles and blogs that suggest that black ribbons are punched with holes or a black magic that covers the proxy sensor on the iPhone. I did not feel that one such solution would offer a professional solution or something I would be proud of in my practice.
After talking to the distributor of my parts, I found that the best solution for this problem is a cheap "sensor cover". This cover is a small film coat whose coat has the same red polarized coating on some sunglasses. This little film is on top of the iPhone proxy sensor.
