iPhone 3GS Crashes (gets Black Screen with White Apple Logo) Mid Phonecall

For the past week, when I make a phone call and use the speaker, after the call has lasted between 8 and 12 minutes; without warning, everything goes quiet and I get a black screen which displays the white Apple logo (the same as is displayed when you reboot your phone).

After a while, the phone comes back on, I’m not required to enter my SIM Pin and everything seems to work fine(ish) from then onwards.

I have done a reset, restore and resync in iTunes, but this still happens.

It does not seem to matter if the battery is 100% charged or not! I have tried a few battery recalibrations too!

I’ve also noticed a slight sluggishness since the upgrade to iOS4 (for example, when you receive a text message, click to view, there is a noticeable delay where the screen is blank (you can see the lines where messages should be) and then they appear/message opens).

Any ideas?

Cheers in advance.

3GS, iOS 4, 32Gb

I seem to have the same problem.
I can't hand you a solution.

This problem exists since my update the iOS4...

Hopefully, Apple can help us.

Exactly the same thing is happening for my iphone since IOS4 installed. Does anyone know how to revert the phone back to the older OS? as a phone which simply cuts you off mid sentence is no ....... use to me!

Oh yeah! Just noticed that my call log is blank too!

I have tried rolling the whole phone back to pre iOS4 but it fails in a spectacular way!

I really hope that Apple can do something about this as I cannot keep having calls drop out on me like that.

Just as a point. When the call has dropped due to the phone essentially rebooting and the receiving phone is also an iPhone; their iPhone seems to lock in the call and cannot disconnect until a forced reboot is initiated.

When you upgrade to OS4 did you update your phone. You have to restore as new phone or else you are going to have problems. Not from back up the rest the OS4 has been rewritten and has problem when you come from 3.x to 4.0. So restore as new phone on iTunes.

Hey Mac Beep Beep,

As did many out there on iOS4 release day, I plugged my iPhone into the PC, iTunes fired up, the software upgrade was found and installed.

Three iPhones updated in my household, all the same model (3GS 32Gb) and yet none of the others have had the same problems as mine.

On top of having the reboot during phonecall issue, my calendar (historic and future) was wiped, birthdays were added to the calendar from the information held in contacts however some (not all) were showing as a day earlier then they should be (even though they are correct in the contacts entry).

Just to clarify, when I tried to reinstall a verified version of the legacy backup (3x), I used iTunes to reset iPhone, re-active iPhone and restore said legacy back up. This failed in a spectacular way so I had to go back to an iOS4 back up.

Note: I had the problem of phone rebooting mid phonecall before I attempted a rollback to 3x.

Any further advice/ideas?

Cheers

If no one can come up with an answer, I’m not currently sure where I stand as to what to do/where to go next.

I got the iPhone 3GS on day of release in the UK therefore have a contract until December (18 month contract).

If the iPhone is unusable as an actual phone; Do Apple/Genius Bar still assist/support my device free of charge and swap out if found faulty?

Restore as a new phone. You plug iPhone to iTunes and then press restore button. Then when it is finished you get a menu that say Back up or set up as new. Pres New and then when it finished add your stuff onto your phone. That it.

Hey Mac Beep Beep,

Unfortunately, setting the phone up as a new phone then adding my stuff has not solved the problem!

The phone still reboots mid phonecall.

Cheers for the help attempt

I don't have this problem on a 3GS updated to iOS 4, but it's clear that a lot of people do. If it were my phone with the problem I would do the following:

1. Delete the iOS4 ipsw file on your computer to force iTunes to download a new copy, just in case the download was corrupted.

2. On the phone go to Settings/General/Reset and tap *Erase all Content and Settings*.

4. Connect to iTunes and restore as a new phone. Do not install any apps.

Test to see if the problem still exists. If it does take it to your carrier or Apple (whichever provides service in your country); something is seriously hosed in your phone. As not all phones have the problem it could be minor hardware differences from batch to batch in manufacturing.
