Any way to fix this without trying to restore?

You don't have an exchange account set up do you? I am wondering if that is caused by an exchange policy.
 
I remember having that issue around a year ago. I would try a reset all settings and then set up as a new phone if that doesn't work. Worked for me back when I had that problem.
 
I'm having the same issue and can't figure out how to fix it. Very annoying. I was trying to find an answer before posting (you know how people hate duplicates on this forum) but not much is being said. This bug is being overshadowed by the reception issue. =(

Autolock after 1 min = no bueno.
 
Hmm, have you tried restore and setting up as a new device?

It should have the options:

Immediately
After 1 Minute
After 5 Minutes
After 15 Minutes
After 1 Hour
After 4 Hours

Trying to avoid restoring but will do if that is the only option.
 
Additional note...I experienced this on my 3GS when I upgraded to 4.0 because well...I was too impatient to wait for the new iP4 to arrive 3 days later =P

It had the same issue but I didn't have time to fix. I've reinstalled iOS4 on the 3GS, set up as new and added each email account (exchange, yahoo, mobileme, gmail regular, gmail google apps) one by one checking the autolock after adding each one.

Autolock is normal on it now, I can choose 5 min. Am dreading having to do this on the new phone...it takes so long get get everything where I like it.
 
There is no 4 hours option on mine. The maximum is 1 hour. I have my company setup email also.

I really missed jailbreak on iphone, so you can download the killexchange via cydia.
 
Im pretty sure it only started happening when I did a reset all settings on my phone, to fix a voicemail problem. It's quiet annoying. Might have to try a restore form backup to fix it. Hope its not a setting saved in my backup somehow!

Same here. Also the Auto-Lock menu is blank. Anyone else?
 
I tried everything to fix this problem on the iP4, reset all setting, reset network settings, etc...but in the end I had to do a full restore and set it up as new. Took a long time w/ all the folders to arrange but auto lock is normal again.
 
I did a clean restore to 'solve' the proximity sensor issue, and now my iPhone wants to 'Passcode Lock = immediately'.

I love my iPhone 4. :confused:
 
Google sync doesn't provide an exchange security policy.

The problem is caused by a change in the way the iphone handles lack of security policy.

OS3.1.3 ignored the lack of policy.

OS4 applies failsafe security settings when the policy is missing.

Google are aware of the problem and are working on a fix.
 
I had this issue. I think it is due to corrupted settings from previous versions of iOS (did you ever jailbreak?) combined with a "reset all settings".

There were assorted other symptoms too (e.g. Emoji keyboard wouldn't activate).

I fixed it by setting up as a new phone…

If I were you I'd wait for a 4.0 jailbreak and then use AppBackup to save your app data when you do the clean install...
 
I've always wandered... what is the point of requiring a passcode after a minute or 4 hours?

What's the point in having a passcode, if someone can look at your stuff for a minute before having to put it in

The point is that if I manage to hold on to my phone for at least a minute and a few seconds after I last used it, then someone who finds my phone will not be able to use it. Simple as that.
 
Many companies enforce certain group policies for cell phones connecting to their exchange servers. If you set up your work email/exchange server then the odds are high this was the cause.

I did the reset all settings in an attempt to fix my proximity sensor issue.
Now I am stuck with no PASSCODE LOCK timer.

Out of curiosity, did anyone get their proximity sensor issue fixed by doing a full restore and setting up as a new iPhone? I assume it WILL fix the PASSCODE bug?
 
How to fix this issue

Hey everyone,

If this isn't being caused by an Exchange account or with a Google Apps gmail account, you can fix this issue by creating your own configuration profile using the iPhone Configuration Utility.

Just make a new profile that has the passcode settings you desire and install.

That should fix it!
