iPhone 4 facetime not working

More info about the problem:

- factory reset fixes problem (with loss of data of course)

- full restore from backup ports the problem over (which we already know from other posts)

- full restore of same backup (from affected iPhone 4) to a newer iPhone 4 works

So, while it is a software issue, it affects only early releases of iPhone 4's

Holdfast4 ... Excellent; what are the model numbers of those two iP4 phones?

The newer one that works is AI332 EMC 380A

The older one that won't work is AI332 EMC 380B

I can confirm that my non-working iPhone 4 is an AI332 EMC 380B. I was however mistaken about my mom's working iPhone 4. It is not a 4S, but the exact same model number regular 4. Facetime on it still works, but I guess it's a matter of time before it stops working as well 😟

I replied to Holdfast earlier, but it's gone missing. I wish it was only the early 4 model, because that might lead to a software / hardware problem center to those, however, it isn't, as written on earlier pages. 4S , 5s and iPads are being hit

my 4S was hit again the other day.....no access and then, stalls during a FTime call, then disconnects Happens worldwide as well, so not a local USA problem

Sorry ~ it IS an Apple problem, whether hardware / software / lawsuit........and it SHOULD be addressed. We are not receiving the features we paid for. That must be a form of Breach of Contract.

question.......is the model number in Settings? My 4S has a modele (it's set to French for school) number that isn't similar to those above, at all

It's printed on the back of the phone.. Under the line Designed by Apple in California. Assembled in China.

Model <model no>...

Yep, mine is also 380B and it doesn't work 😟

On the back, my non-working iP4 says A1332 380A, same as the one reported as working.

The model # I was thinking of is in Settings > General > About and is listed as a MC319LL/A. What about looking at this way of identifying the phone?

It doesn't look like this is a good way of identifying working models. Mine is also a 380A and it doesn't work. Also, I'm surprised the 'A' would be the newer model than the 'B' but they could have worked backwards for some reason.

CatriaaI'll have to look back through the thread because I didn't remember seeing 5's and iPads not working.

iPhone 4, Model A1332 EMC 380B FCC ID: BCG-E2380B IC: 579C-E2380B. FaceTime is not working. What happen?

What were the OS's involved in Holdfast4's case?

What is "special" about Holdfast4's case of cross-phone backup-restore that made it work? Only that target iphone-4 never yet had the broken-FT?

Raises spectre of alternative fix paths (have such been exhausted already)?

Backup(#1) existing iphone 4 to iTunes.

Erase, setup-as-new (verify FT works), backup(#2) to iTunes.

Erase, restore from backup#2 (verify FT still works),

Erase, restore from backup#1. Does FT now work?

Or:

Users A & B with broken-FT iphone 4's make own iTunes backups A1, B2.

Both: Erase, setup-as-new (verify FT works), Erase again.

Exchange phones (but each user keeps original sim cards).

Each user restore (on their "new" phone) their original backup.

any chance something like this could work?

@ GuruNbrNine - The only observation I was making was that it seems to affect just earlier iPhone 4's. THe newer iPhone 4 never had the problem, even when restored from a full backup from the old iPHone 4. THe older iPhone works if factory restore is done but restoring using the same backup ports the FT problem over.

My friend is using a jailbroken ios 6 iphone 4, and is having this issue.

No model other than the 4 is being affected by this problem. There have been plenty of posts by users who own other devices that have been having Facetime issues, but all of them who gave any detail stated that it has been a temporary problem or they were able to fix it by changing their wifi or waiting for the load on Apple's FaceTime servers to lessen.

The specific issue at hand is the instability to connect at all. Neither time nor basic settings are capable of fixing the bug.

We have determined the following:

1. Most, if not all, of the devices affected are "early" iPhone 4's.

2. While many users are on AT&amp;T, this issue is not restricted to AT&amp;T. It may seem that way because of the exclusivity contracts that AT&amp;T had with Apple for the iPhone 4 in the US.

3. The bug is unrelated to non-Apple apps and app data (from the list on this page, the only app I've ever used is Google Maps, which was not mentioned on a few of the lists earlier).

For the user with a 5S who restored from his/her iPhone 4 backup that exhibited the issue: is it possible to make a backup from your 5S and attempt to restore that on your iPhone 4? I would imagine that Apple will not allow restoring from a backup created with a newer model but if it works I'd definitely be interested in hearing! In that case, you could "rent" a newer model and then fix your current phone.

On a similar note, I'd be interested if the user with two iPhone 4's could try this as well.
