We asked you tosend us your iPhone 4 questions , and you ’ve had hatful of them touch on both features and quirky behavior . So far you ’ve ask aboutmultitasking , that new camera , theantenna trouble , and of course : FaceTime . This time around , a fistful of you seem to be having trouble with one of the iPhone ’s old features . Reader Jeff asks :
Since my very first call on my iPhone 4 , I ’ve been have issues with the proximity sensor apparently not work right , resulting in inadvertently switching my call to speaker and mute from my face tint the screen and noticing that the screen was still well-lighted . What ’s the muckle ?
We ’re meet account in our inbox and around the Internet that the iPhone 4 ’s proxy sensor is getting gravel ( to use the proficient term ) . The iPhone has had a proximity detector since the first coevals , which is used primarily to notice when you hold the gadget up to your face to make a telephone set call .
When your iPhone go airless to your case , the detector turns off the display so your face does n’t accidentally end the call or turn on the speakerphone . get out the iPhone away , and the sensor signal the all clean for turn the display on so you’re able to get back to that plot .
On the iPhone 4 , however , some users are report that the proximity sensor is getting stuck in one mode or another . Either it ’s not turn the display off when an iPhone is hold up to the user ’s brain ( result in aforementioned cheeky chance event ) , or itdoesturn the display off but go wrong to re - enable it once the iPhone is pulled away . In the latter cases , the exploiter is often go forth with a black display , unresponsive to touch input for ending the call or switching to another app .
A misfiring proximity detector is indeed pesky , but after a little dig , I do n’t think it ’s near as expectant of a potential effect atthe antenna problem is for some users . Apple has not yet replied toMacworld’srequest for input on this issuing , but I think it might be fairly gentle to fix , or at least forge around until Apple can right deal it .
For newbie , only some iPhone 4 owners are capable to regurgitate the trouble — none of us on theMacworldstaff are experiencing it , and an unscientific Twitter poll discover that great deal of other felicitous owners are n’t either . ( Our confrere atPCWorldweren’t so lucky . ) This powerfully intimate that it is not a far-flung ironware or design trouble , but perhaps a small defect typical of aggregated output , or comfortably yet : just a package problem .
Many unnatural exploiter report that either a options reset or a hard reboot fixes their problem . OneApple keep threadrecommends that exploiter enter the configurations app , then go to General - > Reset , and choose “ All configurations ” at the top ( note : this will not erase your apps , media , or other datum — that ’s what the “ Erase All Content and configurations ” push button just below this alternative is for . “ readjust All options ” just retrovert any options predilection you ’ve customized back to their factory default ) . One Twitter follower , Brian Partridge , reported that AppleCare told him to just use Reset - > Reset web preferences , not all preferences , and it cultivate .
Another choice to try and jump - jump the law of proximity sensor again is to do a soft or arduous reboot . A soft reboot is simply hold the power button until the cherry-red king slider come along , then slide it to really power down the headphone . Once it ’s done , hit the tycoon release again to restart it . This is a small more gentle on your apps than a hard reboot since it gives the OS time to organise everything before powering down .
A hard reboot is like holding the power button on your Mac or yanking its power cablegram — you kill the OS and all race software and force an immediate reboot . To do this , defend the powerandhome clitoris until you see the display go saturnine and Apple ’s logotype appear .
If our hunch is right , and this is just a software hemipterous insect , Apple will surely address it in a gratis update . In the meanwhile , allow us know what your experience is and if you hear about any other answer ( or even causes ) of the job .
