IPHONE 4s call failed??!!!

My iPhone 4s phone call failed more than 50% times, some times people can't hear my voice, is there anybody else has same problem?

I'm having the same problems as many of the posters. About 50% of the the calls I make don't go through !

I make a call and it looks normal, the counter is counting the call but I don't hear anything on the phone. I'm not sure if people hear me on the other side ( I haven't asked) but some have called me back asking of I was trying to call them.

It's pretty annoying. I never had this problem on my Iphone 4, only on my 4s. C'mon Apple, fix this problem and put out an update asap or I'm returning my phone !

By the way, I'm with AT&T.

I have the same problem in UK... It's clear that is another fault of the combination of IOS 5.0 and IPhone 4s... My girlfriend has updated her iPhone 4 to IOS 5.0, but she hasn't that problem.



The signal reception is very poor and my iPhone 4s shows for long period "NO SIGNAL" ( even if my IPad shows full coverage and both devices have the same carrier).


I've also noted that the display of IPhone 4s seems to be yellow compared with the display of IPhone 4... I' m really disappointed about IPhone 4s: it lasts less than 10 hours, it has a bad quality of signal, SIRI works on IPhone 4 as well... At the end I have a phone that looks like IPhone 4, it's more expensive and it works worst

I had the exact same problems. I tried mulitple restores but finally fixed the problem by doing a restore as a new iphone DFU mode. If you want to solve the problem, you have to put the phone in DFU mode THEN restore as a new iphone. I have to iPhone 4s, one that had this problem and one that did not. They are both working perfectly since I put the problematic phone in DFU mode then did the restore as a new iPhone. Problem solved. Try it. But you have to put the phone in DFU mode first while it's plugged into iTunes, THEN restore as a new iphone.

I've had a mixed experience.


  • I've had a couple of calls where the other person couldn't hear me at all but I could hear them
  • I've had calls that imeediately drop as soon as I swipe to answer
  • Calls that fail straight away beep beep beep call failed
  • Calls that drop part way through
  • And some that are absolutely fine...


My old 3GS by comparison was a heck of a lot better at 'phone calls' 🙂
