Does your ongoing call suddenly go mute mid-way? Here's how to fix proximity sensor issue It has been a very common problem that your call will suddenly go mute, or sometimes even on hold, mid-way.

Finally, some relief is in sight for iPhone 4 users bedeviled by the proximity sensor bug. Apple has apparently fixed the widely-reported issue in iOS 4.1 beta 2 -- available to developers.

However, those iPhone 4 users experiencing the proximity sensor issue, or iPhone 3G users cursed with poor performance under iOS 4 are ecstatic over the release of iOS 4.1.

The Next Web reports that an Apple Australia spokesperson said the company’s still working on a fix for the proximity sensor’s wonkiness, and it won’t be cleared up in time for the 4.1 update.

Apple is set to release iOS 4.1 next week and finally resolve the proximity sensor issue plaguing many iPhone 4 users.
