iPhone 4: Proximity Sensor Issues Prominent


Poor Apple. They’ve had a sheer tonne of issues to deal with since launching iPhone 4. From reports of reception issues, to fault hardware buttons, yellowing screens and now another one to add to the list – proximity sensor issues.

For those unaware, each iPhone 4 (and subsequently previous iPhones) contains a sensor which can detect proximity. In a nutshell, this sensor controls when and how the screen is turn off based off the iPhone 4′s surrounding environment.

The main use for the sensor is to enable the turning off of the multi-touch screen during a phone call, to prevent unintended touches when holding the device up to your face. But it’s clear from heading over to Apple Discussions that there are many users reporting problems with the sensor. Thankfully there seems to be a fix which is working for most people.

As first documented by Mac-centric publication @Macworld, a hard reboot seems to kick the sensor back into functioning. The site explains how to perform a hard reboot on iPhone 4 below:

Many affected users report that either a Settings reset or a hard reboot fixes their problem. One Apple support thread recommends that users open the Settings app, then go to General -> Reset, and choose “All Settings” at the top (note: this will not erase your apps, media, or other data — that’s what the “Erase All Content and Settings” button just below this option is for. “Reset All Settings” just reverts any Settings preferences you’ve customized back to their factory defaults). One Twitter follower, Brian Partridge, reported that AppleCare told him to just use Reset -> Reset Network Settings, not all settings, and it worked.

As noted by Mac Rumors, this is not considered a universal problem yet, with many more users reporting they simply can’t replicate the issue.
