Another iPhone 4 Issue: Faulty Proximity Sensor
If we look at the sales then iPhone 4 records the best product launch in Apple’s history, with 1.7 million units sold in just 3 days after its launch, but it looks to be the most faulty Apple product till date as well. The problem started with customers complaining about a yellow patch on their iPhone 4 screen, then came the reception issue. Some also complained about swapped volume buttons, and now finally we have faulty proximity sensors.

Some users complained on forums that iPhone 4 proximity sensor is not working the way it should, as a result people are getting unintentional hung-ups, mutes, and “cheek dials”.

Here are some of the messages from forums:
My wife and I both have the same exact problem with out phones. I was on an hour phone call this evening and my phone muted me 5 times, put me on hold and tried calling my work and then put me on hold and tried to send a text message to my work. This is very disappointing. Ok, that last one with the text message is kind of funny. But for someone who has had apple products for years on end, this is about the worst experience I’ve had so far.
I’m having an issue with the Proximity Sensor not properly detecting when I’m holding my phone to my ear. I can confirm that the iPhone sensor is working by covering it with my finger, but when held to my face, the screen blinks as if it cannot decide to disable the screen or enable it. It results on me hanging up, putting calls on mute, and dialing numbers accidentally while I’m on the phone. This occurs on 90% of my calls. Is anyone else experiencing this issue. I would like to confirm whether this is a software issue (Proximity Sensor sensitivity too low) or a design issue (sensor now placed towards the end of the phone).
I seriously hope that this is some kind of software bug, because if iPhone 4 have faulty proximity sensors then Apple could be in deep trouble, and their dream product could turn into their worst nightmare ever.

Seems like it’s not just the iPhone 4. When I receive a call or give a call on my iPhone 3G and put it near my face it will hide the controls like its supposed to but when I try to, say, look at my contacts by taking it away from my face, it just won’t show the screen. It’s very frustrating. However, I’m sure this can be fixed by software updates!
