The Apple Support Discussions forum has caught the attention of tens of users who have witnessed the same problem. The proximity sensor is the one that shuts down the functionality of the screen when the user holds the phone closer to his or her ears or pocket. This sensor seems to have started showing indications of malfunctioning.

From the forum, it is understood that the problem varies from mid-call hang-ups to muting calls. It has also been reported that the screen does not go black, as it is supposed to, when the user receives call or initiated a dial but the functionality of the phone remains intact. This hampers the communication or call as the touch of the face can cause anything like accidental three-way calling, facetime initiation attempts et cetera.

The support forum has come across growing number of users who are in favour of the discussion topic; a lot of them providing suggestions for an appropriate solution.

The best suggestion as per the forum is to sync the phone with a computer and backup the files or information saved in the phone. With innumerable releases by Apple, it seems to have overlooked some features that are close to any user’s day-to-day life.

After having done that, perform a restore and find out for yourself if the process works or cuts down on the problem. If the problem continues to appear, do a restore once again and adjust your phone as a new phone. Restoring does not save any data that previously existed in your phone. In order to make sure the data is not lost take a backup elsewhere.

While a lot of users have been debating about resolutions that can be done privately without having to leave ones home, some suggested that contacting AppleCare by phone or by visiting their service center was a “painless” process. Despite all the unnamed resolutions, the users must not forget the fact that iPhone 4 is still new to the Apple family and therefore may face a limited supply. Hence, the need for the moment is to get it operated before it is too late. If the problem continues to appear, do a restore once again and adjust your phone as a new phone.
