Reliable Fix for iPhone 4 Proximity Sensors
When the iPhone 4 was released in June of 2010, that wasn't without it's discuss of glitches. The first reported glitch was with the iPhone 4's wireless 3G antenna. It was suspected to cause poor reception and then a high volume of fallen calls. The next reported issue was along with the iPhone 4's proximity sensor. Apple addressed this problem on the software stage, with the release of iOS 4. 1.

Since the iOS 4. 1 relieve, there have been many questions as to set up update resolved the iphone 4 proximity sensor issue for good. From my own experience, I haven't had almost any complaints since this software programs update was made general public.

Some of you may be?? wondering, "What in the modern world is a proximity sensor is and what function will it serve? " Without getting too involved, every iPhone (including the original iPhone 2G, 3G and 3GS models) have a proximity sensor. This sensor emits an infrared (IR) gentle that detects the presence of an solid object (such as a head or hand), while you have a call in progress, or whilst you're listening to a voicemail message. When it detects a compelling object, it turns your iPhone's LCD panel off. This is a purpose you'll probably never miss until it's no longer working.

The function in the proximity sensor actually provides two distinct advantages. First, you aren't muting ones phone, accidentally pushing control keys, or hanging up on the callers with your cheek. Additional advantage is that that conserves power consumption together with improves your phone's battery life involving charging cycles.

For an Apple Certified Macintosh Technician who makes a living supporting and fixing Apple company products, this is a concern that could not be ignored. The reputation of my business hung inside balance of to be able to find a reliable and professional solution for this purpose problem. I've done extensive research and testing on this topic and feel such as I've made significant headway with resolving this annoying glitch..??

In the four years that I've been repairing iPhones, it's only been just lately that I've began experiencing the problems that have been widely documented and reported. Since the release associated with iOS 4. 1, I haven't seen any cases in which the iPhone's proximity sensor malfunctioned on a phone that hadn't recently been modified. When I say "modified" Air cleaner will add a phone that provides undergone a color the conversion process, or one that the front glass and LCD had been replaced due to the phone being dropped and receiving the original glass broken. I noticed that the occurrence was more apparent after having a color conversions had been performed.??

Since the proximity sensor over the iPhone 4 is on the iPhone's mid-frame and is not a part of the front glass together with LCD assembly, I had never questioned the products the parts I had been purchasing. With that in mind, I began testing every phone prior to repair. I wanted to make sure that the phones were functioning properly, prior to repairs, or color conversion rates being made. So very far, I have yet to uncover one that wasn't working just fine before the repair. It turns out, the problem was gained via two factors.??

1. The unique sensitivity of each i-phones proximity sensor.

2. The proximity sensor cover on most of the replacement glass is not tinted as dark. This allows too much light to feed.

I've read over many articles and blogs that suggest using dark tape with holes punched available, or a black magic marker to hide the iPhone's proximity sensor.?? I didn't believe that either of these fixes offered a specialized solution, or one that i would even be proud to employ in my practice.??

After talking to my parts distributor, I recently found the best solution for this problem is an inexpensive "sensor cover. "?? This cover can be a small piece of film which includes a coating that looks to be the same red polarized filling on some sunglasses. This small piece with film is installed excessive of the iPhone's proximity sensor.

Right at the end of the day, it would appear that too much light gets in and confusing the device. The proximity sensor covers filters excessive light from entering the iphone and there by?? solves the challenge.??
