iOS 4 causing iPhone 3GS reboots?

The iPhone 4 and its antenna issue has been gaining all the headlines but behind the scenes, 3GS owners are facing an issue of their own. After reporting that iOS 4 was causing batteries to drain rapidly, users began sending Neowin reports that their 3GS phones were rebooting while trying to make calls after updating. 

The problem being reported is that when either placing or receiving a call, the phone will reboot itself during the call. As one can imagine, a phone rebooting during a call renders the phone useless. The Apple support forum has a 33 page topic discussing the issue where users are complaining about their phones rebooting during calls of varying length. 

"After about 4 or 5 mins in a phone call my iPhone 3GS reboots itself for no apparent reason. this did not happen before I put the iOS4 update on it. Is [there] some way I can stop this [from] happening, or revert back to the previous version? "

There are countless reports of this issue across a wide range of geographies and networks.  While there are suggestions the phone is overheating from the iOS update or there's a software bug, no one has actually determined a solution to the problem. At the time of writing, Apple has not admitted or acknowledged the bug but that could change after the iPhone related event being held on Friday. 

The bigger issue for the European users, outside of the UK, is that the only known fix is to revert your phone back to iOS 3. While this can be done by users in the US or the UK at Apple stores, those in other countries do not have this solution as the phone is sold by third party vendors. Because of this, users are stuck with phones that reboot after a call of a few minutes without a solution.

It should be noted that the Apple admitted to a software bug showing bars as artificially high in pre iOS4 and thus updating to iOS4 is likely to show less bars now that it has been fixed.

No one has really picked up on how suspicious this is.

Everybody sell your iphones - regardless of model - and buy a Nexus One!!!!

Funniest thing I've read all day!

beautiful apple is on a roll, did anyone decide to do a full test on all older iPhones. what is worse iPhone or ios or iquit on apple Inc. Steve jobs I present the slow and painful death of apple Inc. Man that's getting said way too much.

iOS 4.0 has turned my 3GS in junk.

I've tried restoring back to factory defaults (a format and clean install of the OS), and it doesn't change anything.

iOS 4.0 is just horrible.

You should probably bring it to the Apple store and have them take a look at it. What you're describing isn't typical and there could really be something wrong.

YES! This happens on my 32GB 3GS after updating to ios4 - I've found that killing all my apps when I make a call seems to help, but not all the time.

I have the same model, but do not have the issue. Have you tried a restore?

Running iOS4 in 3GS since day 1 of the update, no problem of any kind.

Reception, phone calls, navigation, everithing works quite well.

Some sites report about 50 million iPhones (since original), of course that problems have to happen. The main problem is generalization, the idea here us like the problem is in almost every 3GS phone. I think a poll could give us an idea of how big the problem is? Of course if people is honest with the vote.

People without an iPhone here would probably vote that theirs is having issues. Not that I am denying that there are issues with the phones, but I only ever hear about them from people who don't own or use them.

That's a fairly large ASSumption don't you think?

Given the attitude toward all things Apple here, I doubt it's far fetched. As far as the second part, it's the truth. I haven't heard a complaint from a single iPhone owner that I know personally. And literally, more than half of the people in my company own one.

This happened to me, but I deleted all data and setting and did a restore from backup....seems "OK". Although today my iPod content has disappeared after a sync....Last apple product for me!

No problems here on my 3GS since upgrade ,never had that problem while I was testing the os as a developer either .... I guess people just like to pile on.

Well bugger me. Since you reckon there is no problem, all the ppl out there whom must be stupid then.

You're attitude to the fact that there is a issue amazes me.

Come down from your bloody throne when you wake up

With all of the problems surrounding the iPhone, iPad, and Macs, I must be one of the lucky ones that haven't experienced any of the above. My 3GS has been on without a crash or unexpected reboot since the upgrade on the 21st. I only shut it off manually twice while traveling internationally.

I did notice that too. But not during a call. I left it on yesterday and it rebooted randomly and would flicker and bootloop and then come back. It was the strangest thing.

What really sucks is that I want to sell the phone and if more people catch on to this they are likely to not want to purchase my phone with the iOS4 update. I tried to downgrade and it didn't let me. I will try again. Ugh. Good thing I am not on AT&T's service or the Iphone anymore. I used 4Gigs of data this month

The only problem i have with my 3gs running ios4 is it wont work with my car stereo anymore. I have tried all the "fixes" and none work. It was fine before the update!

Big Daddy Cool said,
Its easy to downgrade from OS4 to OS3 , I did

me too. not sure why people aren't googling this... they are most likely apple users who have never been giving too many options and don't know how to explore different ones that aren't right in front of them.

Apple stopped allowing you to download to os 3.x.x after releasing os4. They simply need to allow this again.

Since "upgrading" my 3GS to OS4, my phone signal is absolutely awful - regularly drops from full 3G to searching with no service. Battery life is also dreadful now. The phnoe has to be charged every day now.

What a mistake going to OS4 was!!

Come on apple, let us go back to 3.x.x PLEASE!!!

I don't know why people keep saying this isn't possible. just google a bit and you will find the old OS then google some more and you will find a shortcut you can use in itunes so it asks you what OS file to install on the phone. and you just pick the one you downloaded.

Not had any call cut outs here, what the hell is going on !?!?!... So many people with so many different problems going on.. Apple sort it out before people walk away from your over priced crap. I love my 3gs but the update is buggy as hell it seems

He guys I'm with Rogers wireless and i do owned a iPhone 3GS on ios 4 and I got no problem at all. I thing there is some peoples that smoke a little bit too much of that green stuff LOL

you ever done software bug testing? sometimes you have to do 10 different things in a certain way and in a certain order and only then does the bug occur. this is why it's only happening with certain people and this is why it needs to be fixed. the bug IS there, just because the lucky people haven't stumbled on it doesn't mean it should be ignored.

it's like trying to prove a theorem is true. you can give a million instances of it holding up but only 1 counter example breaks the whole thing.

Apple is growing to big to fast. iPad had issues, iPhone 4 has issues, and now the new iOS is having issues. Three products they released recently all with problems. Poor testing yes...or they just dont care as long as the check clears.

I remember mentioning to an apple zealot once, that apple growing too big and gaining a bigger market share is actually contrary to their business model. They are a niche company, and count on the unwaivering support of their niche market. The normal consumer is far less forgiving, and I think thats the main reason why so many of these issues are coming to light (apart from the fact that they are product faults).

I agree with you 100%... my dad used to tell me this when I wanted a mac and i finally see his reasoning.

Karma is a b***h, Apple. This is exactly what you deserve for constantly putting down your competition. Your arrogant ways will keep me from considering purchasing every single one of your products.

Well i had the 3gs and when i updated to iOS4 i had the symptoms as above. It was very random when it rebooted in both receiving and making calls - it really did annoy the hell out of me cutting out in the middle of the call. I contacted 02 to start with, who then put me through to apple so was obviously aware something was going on here.
The funny thing was while i was explaining to the apple tech support it cut off !! rebooted lol.
So i had to use the house phone and start from scratch again with another techie.
The end result was a phone replacement - relatively painless and very quick tbh , it came with the old 3.1.3 and auto updated as soon as i connected up etc.
So far 1 week in no concerns, so it may be batch related ?

thx

Probably a fraction of the people experiencing this but as usual it gets all hyped up as though it's affecting everyone, lol, gottoa love the internet.

Bad statement. . .you can prove that it is only a fraction. How big of a fraction are you talking about?
Silly statement.

Silly statement.

If it was big enough to be a serious fraction then the phones would have been recalled. The thing is not everyone is affected by all of these issues so the statement isn't silly...

Most numbers can be expressed using fractions.

as a mathematician I couldn't let this one go. the cardinality of the set of irrationals much larger than rationals. so there is no way you can say most numbers can be expressed as fractions.

Whilst accurate and true... I think that for what we are discussing here which is rational cardinality... His statement is true?

So lousy.... I want new ipod for myself and new iphone for my mom as a gift. But if this situation keep going on badly like this, I don't have anything more to say.

.Neo said,
I haven't heard a thing about this issue.

I hadnt either but when I posted the battery story, I was flooded with emails telling me about this issue that pointed to the support thread...its been covered up pretty well by the other issues.

Well I asked around and so far nobody experienced any reboot issues. Others, including my iPod touch, did experience the faster draining of battery life.

ReDFoX2200 said,
Did they ever test before releasing?

The OS 4.0 was tested with developers for weeks before its release, just like OS 3 was and OS 2 was (OS 2.0 had a fair few teething problems until 2.1 was released if I remember right)

Sounds like MS weren't so wrong when they described it as Apple's Vista.

I think they were thinking about their own mobile products. Microsoft Kin anyone?

There isn't anything technically wrong with the Kin though that I know of. People just don't want it. lol

mostly people didn't want to pay the full data plan, and it shouldve been a cheap device to begin with. At least ms admitted that it failed, Apple has yet to do that

.Neo said,

Wait, you trying to compare MS and to Kin to Apple and the iPhone? hahaha. Nothing wrong tech wise with the phone...it was just ugly looking and no one wanted it. Completely different.

the kin lasted longer then the iphone 4. iphone4 was dead on release.

no... Kin is the Microsoft Bob of the new decade

You can't do math apparently.

PS Microsoft's response was about the iPhone 4, not iOS 4.

It's a failure all the same.

Kin Two looked perfectly normal. Kin One was ugly.

I have a 3GS and mine has yet to reboot since I installed iOS4, however I get fewer bars of 3G than I did when I used 3.1.3. When the antenna problems first started some said it was partially a software problem that affected the 3G and 3GS to, I wonder why everyone has stopped saying that.

Same for my 3GS. The battery seems worse, and while I am at work I get fewer bars (and for awhile I was not able to get any data when I used to have a good signal here).

It's possible it's AT&T, but that would be awfully coincidental.

Thankfully, no reboots yet.

Because saying the antenna issue is a software problem is like saying nobody has ever surfed for p0rn on the internet.

My wife's iPhone 3GS is draining the battery in record time and rebooting randomly. It's causing me quite the freaking headache!

Funny my 3GS on Rogers has none of these issues. In fact the battery life is better and my phone is very stable

Same my 3GS has had 0 issues since the update. Granted I have enough common sense to periodically go through and close all the apps running in the background so the multitasking doesn't kill the batter.

Same here, not had any of those issues. The only thing I have noticed is the amount of time it takes the phone to boot up....

Those apps aren't actually running in the background............ only a select few like Pandora Radio that actually require it.

DON'T shatter their illusion!! apple finally made it seem like they are giving us what we asked for... if people are aware that they are just being lied to but a clever interface then apple will have to think of some other way to lie to the commoners.

Ye because an OS cannot control the hardware it runs on?

You can however, provide something to allow users to easily downgrade back to a previous version without loosing data.
