iPhone 3GS drops call and reverts to apple logo

Fully charged iPhone 3GS with masses of free capacity drops calls after a few minutes chatting and reverts to apple logo. I am not sure if is rebooting but seems to come back to life a couple of minutes later. It has done this for months if not years and across several firmware versions. It may very well have done it from new. Is there an internal log that I can get at to see what is happening ? Carrier will blame phone and Apple will likely blame carrier. Someone help please. It's been a great phone otherwise. Note have not upraded to iOS6 because of crappy mapping. Google Maps is one of my most used apps.


Regards

MacBook Pro, Mac OS X (10.6.8), 17"

Ok so lets assume you know what you are talking about... and the problem is what ? That Apple sold me and posibly tens of thousands of others faulty hardware and have simply ignored the problem ? And on top are going to prevent me from finding out what the problem is by dening that the problem is logged in the OS ?

Further to all this I believe this call dropping only happens on incoming calls amd always about the same time after the call comes in. I will see if I can start a timer to record this.


BUT, what I would really like is to be able to diagnose WHY the call drops. There has to be a log or an app that can monitor the voice call cannection to determine if the phone drops the call or if the network terminates the call or whatever. How else can phones be fixed if this is not possible ?

If you go into Settings, General, About, then scroll towards the bottom, there is an area called Diagnostics and Usage. However, I don't really know if you would be able to see if the phone dropped the call or if the carrier dropped the call. There are so many different variables when it comes to call drops, carrier, tower, phone, etc. You can look at this diagnostic area and if there is a crash report it would show. However, again, I'm not sure if a dropped call would generate a crash report here. Guess the only way to find out is to check. What kind of signal strength are you showing when the call is dropped. Is this drop always happening in the same location, or in different locations. Have you contacted your carrier and have them check their end? Have them supply you with a new SIM card and see if that corrects things?

Thanks Chris, That is really useful information. There are a heap pf panic reports in this area and it looks to me like the last one was when I had last dropped call. Now I know this is there I can look each time to see if a new report is generated. The comment for last panic was WDT Timeout whatever that means. A bunch of other data in there also. Have managed to cut and past the panic report so now I can do more research. Thanks again. Very helpful !!!😀

Been through the whole wipe and restore routine again.... Made a call from my landline to iPhone and it stayed up 15 minutes. This is longer than the usual time when it drops the calls. I have not re loaded any of my previous apps at this point. Now I will add them a few at a time and see if the problem returns.


Right now I am thinking there is an app doing something nasty that causes the calls to drop. It would have to be something that's looking for data or something like that. Lets see.

Ok looking at you fighting with the fist person to respond earlier he is correct even apple geniuses cant access things like that. And most likely apple didnt ship thousands of faulty devices you most likely got a bad one in the shipment just like when i got my iphone 5 from verizon the speaker didnt work right. Its mostly your fault u didnt take it in in time while its still in warranty if it did it when u first got it then why didnt u go get it replaced? And to fix your problem it might be if your trying to do voice and data at the same time, as the 3GS is a older phone and might not be able to handle the high load anymore and the phone might have slowed down a bit.

This is a load of rubbish and adds nothing to the dscussion. If you took 5 minutes to Google the issue you would see there are posts about it on bulletin boards all over the internet. "trying to do voice and data at the same time" how do I stop that from happening fpr goodness sake. If I am on a call and some app I have decides to do some data stuff what is supposed to happen ? Apple approved ALL the apps I have on my phone after all.
