What happens at end of call

This is normal IF the phone was in standby and locked prior to the call.

If you think of it, would you want somebody to take your phone, call it (or wait for a call) and have it unlocked after the call for them?

If the phone was not in standby when you get a call, ending the call will take you back as you want.

It depends on how long the call is. For a short call that completes before the sleep timeout it will go back to the Phone screen. If it's a long call and has already timed out it will go to sleep at the end of the call.

If your iPhone is asleep when a call is received, when ending the call your iPhone returns to sleep.

If your iPhone is not asleep when a call is received, when ending the call your iPhone should not go to sleep.

I HIGHLY recommend setting a passcode. If not, anybody that gets your phone can not only call with it, but email with your accounts, buy via iTunes WiFi store, get access to all sites you have logged into and that site allowed saving login info, etc. *A LOT* of personal data will end up on your phone.

So yes set the passcode option. And note, Apple was good in this reguard. You can set it to require a passcode everytime you unlock, or you can set it to only require a passcode after x number of minutes have passed since it got locked (standby by timeout or by lock button). I have mine set to 5 mins. So once I am done using it (lets say sending a SMS) and I click lock and put in my pocket. If I pull it out again within 5 mins, I only have to slide to unlock, I will not have to enter code. But if longer than 5 mins then have to slide, then enter code.

That makes complete sense, and explains why my iPhone would sometimes go to sleep after ending a phone call that I placed, specifically one that lasts more than a few minutes.. it was annoying, but if you think about it, there is no activity on the screen or buttons(if the phone is to your ear) and extends past the inactivity time to auto shut-off.

Here's another good reason to set a passcode. If you don't have one, anyone who picks up your phone, can set a passcode.

In other words, you set your phone down for a second, or lend it to someone to make a quick call, whatever. That person sets a passcode before giving it back to you. You're now locked out of your own phone. A restore might fix it; I haven't tried.

If you've set a passcode, it cannot be changed or disabled without entering it first.
