My experiences of using my iPhone 5 as a phone (whether to other iPhone 5 or not) has been stellar. Sound quality and overall experience is much improved over my old iPhone 4. My iP4 frequently dropped calls and I had proximity sensor issues the entire 2 years I used that phone. I have not noticed any of that with the iP5, and the sound quality is noticeably better.
Are you or the other caller touching the mic on the back of the phone by chance? I have noticed that I sometimes accidentally put my finger over it resulting in a scratching or rustling sound.
To me it sounds like when you have the volume turned up really high but the actual person speaking is talking quietly. As soon as they stop talking it goes very quiet which must be the noise cancellation kicking in. I get the same hissy noise when listening to my voicemail. It sometimes even sounds a bit distorted too.
Still can't decide if it's hardware or software. I'm going to book a genius appointment for next week and see what they have to say about it.
Same issue here !
Provider : Telus
Iphone 5 : We just ordered 75 iphones , so far ,issue happen with all of them no matter how hard the signal is.
We have phone in montréal , québec , trois-rivière , same issue .
On 3g : the call quality is a bit improve but still call quality between Iphone5 are not acceptable.
The issue only happen when calling Iphone5 to Iphone5 . The sound get very poor, tunnel/robot sound a like . If an iphone5 call any other phone , no issue . We are not picky on the call quality but iphone 5 to iphone 5 is what we use the most.
Try to contact apple with our source but no luck . We are now asking Telus to just do the test for us and report the bug to apple on their own .
We will check as well if beta version of IOS is solving the isssue or not...
Thanks for taking time to reply. I'm pleased in one way it's not jus tme with the problem. Have you tried doing a full reinstall or iOS and then restoring from backup. I've read this has solved some peoples problems? I'm going to give it a go but it's just time consuming and pointless if it doesn't actually solve the problem.
Thanks again for your time.
