IPhone 4 Bluetooth Issues

IPhone 4 doesn't allow reasonable range and other issues with bluetooth headset. Fyi, tried with Apple Bluetooth headset which worked perfectly with IPhone 3G & IPhone 3G-S. Issue, you can have IPhone 4 in shirt or pant pocket and bluetooth will disconnect. Also, you can have IPhone 4 inside car and close the door while standing right outside the door and bluetooth disconnects. This never happened with previous models including IPhone 3G-S with IOS 4 installed.

Other bluetooth issues: as others reported - muffled sound quality to person your talking to. Time delays and disconnects with bluetooth Uconnect. IPhone 4 won't let you change between your car audio phone feature back to IPhone 4 without freezing.

I have the Motorola Rokr S9 HD blue tooth headset. It works if you don't touch the iPhone anywhere on top of the device. Its fine in an armband. Its seems like if the face camera is covered and the the lock button is touched the phone locks BT transmission. I have tested the combos. If you cover the camera, no problem. if you touch the top of the phone it rerely has a problem. If you touch both the phone seems to lock. There is no setting in general to contol the face lock. I think it is a functon of the feature that locks your touch screen when you use your phone as a phone. Anyone have any thoughts on the issue or a soultion?

I had an iPhone 4 which worked fine with a Jawbone ERA, but now my new 4s won't recognize it no matter what I do. It recognized it once before I updated to OS 5.1. Now, nothing. I've turned off the wifi per the suggestions above.


Any other suggestions? Is there any concensus on whether the Samsung works better or the same as an ERA with a 4s?


I drive with hand controls and if this is not solvable, affordably, I may need to go to Droid during my 14 day trial period. Rediculous.


Thanks for any good input.

Brief update: Jawbone is having problems updating with the newest Mac OSX Lion update. I wonder if it's having similar problems with OS 5.1. (I removed my Otterbox Defender just to make sure it was not causing interference, and the 4s still won't recognize the ERA after the 5.1 update.)


That aside, is there any concensus on an affordable bluetooth that works with the 4s? I have seen a couple people mention Plantronics, but two of those worked fine and first, then did not work well at all, with my 4. I'd consider the Samsung if it's not expensive.


Thanks again for any suggestions.

I'm having problems recently too. I have an iPhone 4 (refurbed), located in the USA, my provider is AT&T. My Bluetooth earpiece is a Jawbone "Aliph" series. Worked great with my iPhone 3G. For a while, it appeared to work fine with the iPhone 4 too, but I'm having the same problems lots of people have reported here--if you put the iPhone in a pants or jacket pocket, connectivity drops or the voice quality becomes so bad it might as well drop. I'm not 100% sure, but I think I noticed this problem really become bad when I upgraded the iPhone 4 to iOS 5.1.1. Hopefully, Apple Inc is listening to our complaints and will fix this in an upcoming release. It'd be great if this were a software fix, i.e. through an iOS build, rather than hardware.

Ok, here's my 2¢.


I have found the same issue (people not being able to hear me talk or me sounding like I'm very very far away) with the Voyager Pro and Voyager Pro HD. I have found that it comes and goes. Sometimes resetting iverything works, sometimes it doesn't.


One thing that I don't see mentioned anywhere is the fact that, in my experience, the headset works fine with the Voice Memos recording feature, even when it's not working with phone calls. To me, that seems to point to an issue that is specific to phone calls over a Bluetooth headset, rather than just a problem with the Bluetooth in general.


I've tried multiple other headsets with my iPhone 4 (iOS 5.1 and 5.1.1) and not experienced the same issue. I have had no problems with any other headset. It seems like the problem must be with the firmware on the Plantronics headsets as far as the sound issue goes.


The connection problems, though, seem to be more universal to various brands of headsets. As it comes and goes, and is 4/4S specific, it almost certainly must be related to the antenna on the phone, therefore more difficult to fix. I'm guessing that Apple has found that to be the case, which is why they've been silent on the issue.


I'm hoping that the iPhone 5 finds a solution to this mess, and I'm hoping that it comes out soon! I have the summer off from work, but don't really want to go back to work in the fall without the benefit of the fantastic sound quality of the Voyager Pro HD!

I have posted in other places on the Apple forum with similar problems using several different bluetooth headsets. I can now confirm however that the only headset that has worked for me is my new Bose Series 2, someone else said the same thing somewhere else on the forum.


I would have tried it months ago but my local Apple store here in Birmingham Uk had only the right ear version and I needed the left ear one and they wern't that helpful in offering to get any in. In the end I ordered direct from the Apple website and in all fairness now being able to use my Ip4 without messing about with a cabled headset which was a pain has been a godsend and put me back to before I first got the Ip4 nearly 2 years ago when I was using my Nokia and eveything worked fine.


The one thing I would say though is under fairly heavy use the battery on the Bose 2 doesn't last as long as I would have expected but this isn't really a major problem as I can just keep it topped up and could be because I'v not used one properly in a long time and have forgotten how long my old one lasted before.


Hope this helps.

Yes there is a annoying problem with the Bluetooth devices on the iPhone 4 & I worked out that if you disconnect from your wifi by activating the personal hotspot then the Bluetooth will work! However this is only a work around & apple will have to fix the problem because people like ourselves have paid a lot of money for faulty goods! The word will soon spread if apple does not resolve this issue quickly, & the result will be that Samsung will further dominate the market with their intelligent products.. (galaxy iii) of which has a good write up.


Thoughts anyone......

I have recently switched from Blackberry Bold to iphone 4s due to company decision. I use the phone as a phone more than texing/surfing the net or whatever.

The Bluetooth quality with the same Plantronics Voyager Pro and iphone is pitiful. I have used several Plantronics Bluetooth headsets over the past 7 years with outstanding performance and clarity, using several different brands of phones. I used several automobile built in Bluetooth devices and the current Plantronics Voyager Pro with great success with Blackberry, but just about unusable with iphone. Every minute to minute and a half there is a buzzy static occurrence. During a conversation the words sound like the person talking is going over a rumble strip, audible to the listener on the other end or myself. When on a multi-hour conference call, I switched from car to Plantronics to phone to wired headphones. the last two were fine the other two resembled the same static garbled sound. Even when using SIRI over Bluetooth you can hear it.

Anyway, I have spoken with Plantronics, Radio Shack and several other resources who corroborate this short coming of the phone. Back to my original statement, it is a phone right??

So after combing through this post i tried the Bose Series 2 with great results. I would say it is equal to my Blackberry with Plantronics.

So if you want to save a lot of time, but pay a premium price, get yourself a Bose Series 2!

Yeah. After a year of frustrating tests, I think it's Dragon Dictation and Shazam that make my BT stop working. It's a software issue. I have done lots of personal tests opening apps and then calling someone, then moving away from the phone (distance between phone and earpiece), then closing the app(s) and then calling again -- repeatedly, to replicate the problem. Very disappointing, actually, since it means that every time I get a phone call, I have to get out of whatever app I was using before...

Well I have to agree apple does suck we're all sheep buying thir crap over and over again even though It doesn't work.

The 5 works fine with the jawbone era. I can put the phone in my pocket unlike the 4 and 4s.

Could be the Lowpower Bluetooth 4 that they switched to after the 3.


F... My **** screen is acting up and I can barely finish this message.

What a crappy company. Hey thanks for shipping this American product directly from china.

I bought 3 new plantronics bluetooth headsets. The latest was 200 euro. I dont think it has much to do with ios6. I had poor sound quality even before 6. I have a 4s iphone. I can hear every one perfectly, but certain people cannot hear me. Some not at all.

I believe it may have something to do with what phone the OTHER party has. I find blackberry users, iphone, android etc... Can hear me just fine. But those with an older phone... Not so much. My friend with a samsung smartphone,(pretty old model) can never hear me. Same as another friend with a very old nokia of some kind.

Its funny because when i had the blackberry bold from 2 yrs ago...everyone could hear me always.

Now I am forced to talk with no bluetooth, because several people complain they cant hear me.


I dont like this. I had a brain tumor a few yrs ago, and I absolutely do not like putting the phone to my ear. Only for this reason, I truely regret buying the iphone.


It may be an apple motive to get everyone to buy iphone. Anyone else able to pinpoint the same problem with the quality of phones our friends have, and us not hearing them?
