Locking iPhone during a call!

NOTE: I posted this on official Apple site forums - thought I'd paste here too.

OK - I bought my iPhone 4 the day it came out - the first iPhone I've ever bought! Great phone - except for this issue as titled in this topic! I've seen this issue discussed in various places and but I hope this topic/solution gets pulled to the top of the list in some way or set to a Sticky:!

Just like you, the number of times I kept having the problem of pressing the mute/hold, keypad, speaker, add call, FaceTime or contacts button during a call with my cheek or hand (sometimes), ultimately cutting the call or making funny beepy noises!:mad:

Argh annoying! I just wanted the iPhone 4 to lock during a call!

Nevertheless, I just so happen to randomly come across the procedure, to prevent this from happening.

Let me clarify the situation:

1. We know the proximity light sensor is crap. Check.

2. We know when you hit the power button during call, you expect it to lock - instead is cuts the call. Check.

3. We know when you press the Home button - it takes you to the Home Screen with all your App icons (a worse nightmare now, as you have more icons to FaceTouch with)! Check.

4. We know you CAN lock the screen IF you have a handsfree plugged in OR if you put it in speaker-phone mode. Check.

But what do we want:

The ability to LOCK the phone, DURING a call, using the handset (the bit you talk to in the bottom of the phone!) WITHOUT switching into speaker mode or using a handsfree and not have to WORRY about the line CUTTING.

Phewf - Hope that makes sense!

Solution

Having recently put iOS 4.2.1 - I thought this solution was lost, when I tried it, it didn't work :mad:. But then luckily I realised a difference about the set-up of my phone I had previously. When I re-set it up like I had it previously - the lock method worked fine again. That difference was the setting up of a passcode to unlock your phone. Phew!

So, here's what you do - there are two scenarios:

Scenario 1 - You're the caller

1. You need to set up a passcode to unlock your iPhone each time you lock it. So:

Settings --> General --> Passcode Lock --> Turn Passcode On --> {set your code}

So this means, every time you unlock your phone, it will ask for the passcode to get the Home screen.

2. Call someone.

3. Now press the following in this sequence:

Speaker --> Power Button --> Slide to Unlock --> Speaker --> Home Button

4. If done correctly, it should still be in the call and your screen is now locked, with the "Slide to Unlock" displaying - Yay!

5. For "double-the-lockingness" - press the Power Button. This turns off the screen completely, also saving on battery power.

6. To End the call either:

a) Other side hangs up

b) Press the Power Button --> Slide to Unlock --> Enter Passcode --> Taking you to the Home screen, tap Green Bar at top --> End Call button.

Scenario 2 - You're the receiver

1. You need to set up a passcode to unlock your iPhone each time you lock it. So:

Settings --> General --> Passcode Lock --> Turn Passcode On --> {set your code}

2. Just press the Home button!

3. To End the call either:

a) Other side hangs up

b) Press the Power Button --> Slide to Unlock --> Enter Passcode --> Taking you to the Home screen, tap Green Bar at top --> End Call button.

Final thoughts

So yeah, that last step might be a little frustrating - but it's much better than having FaceTouch cutting the line!

I hope this helps - I use this all the time and it works fine for me. I really hope it does for other people.

I should have shared this a few months ago - so apologies for not making the time to type this out.

Happy calling! Finally!

Zayd.
 
Sorry, I fail to see the problem in the first place.

And I've only just read the "sequence" and forgotten already. Won't work.
 
Pretty elaborate solution for a problem I have never experienced
I can't say that I would ever use it

If I had to go to all that trouble, I would just plug in my earphones

The problem is, I as many others, find the proximity light sensor does not always do a great job at turning off the screen during a call - especially when holding the phone near to your face.

Ultimately, you end up pressing some of the touch screen buttons on the screen causing the call to drop.

The sequence is one you would remember if you tried it more than once ;). Sorry to hear it doesn't work for you. I'm glad it does for me :).

seriously

20 step process for a problem that really doesn't exist

my theory on this is people with the problem must be very jittery and continually move the phone on an off their faces

I hold my phone on my ear, and I've never had this issue
 
Never had that issue either. As long as the sensor is covered, the phone will blank out. It must be that you are holding the phone in such a way that there is light hitting the sensor.

Yeah I guess that may be the case for some people. For me this situation arises in two places mostly.

The first is when I am in bed ! :rolleyes: Sometimes I just want the phone to stay locked and not have to prop the phone up to my cheek with my hand the whole night, as I talk. Instead I just "lye" on the phone, with the phone locked and even if I move and the proximity light sensor kicks in, the screen that's shown is always a lock screen - so again, I don't end up pressing the end call button :D. This has happened quite a few times surprisingly!

Secondly, when I am on the move, walking fast pace, hand sometimes moves the phone to angle closer to sunlight - turning the proximity sensor on and off constantly.

The situations are specific and are variable depending on one's preference!

No doubt however, when stationary, sitting down and just chillin' - the phone turns off fine.
 
Wow, just get the phone replaced. Much simpler solution.

I've never had a problem with the proximity sensor and most people have no issues like this.

:confused:

Ee - yeah I guess could get the phone replaced. I did notice when doing some forum searches - some people had started topics on the issue.

Just thought I'd post a single topic solution. All good either way. :rolleyes:

No problem. There certainly are some who have experienced the proximity sensor issues, so it is a valid discussion. I have been fortunate enough to have not had it myself, and I think if I did, I would probably seek a replacement or use the headphones.

Always good to have new insights and solutions.
Hopefully it will be helpful to someone how is experiencing the problem.

I think we at MacRumors have come to the conclusion, that the problem doesn't exist .

In fact are you sure u have the latest release? wasn't there an update for proximity problems in the first minor update?

Check this:

http://discussions.apple.com/thread.jspa?threadID=2475509

In fact it got SO big of an issue that it had to be split onto this thread:

http://discussions.apple.com/thread.jspa?threadID=2505360

AND then this thread:

http://discussions.apple.com/thread.jspa?threadID=2551039

I think that topic's big enough to demonstrate this was an issue... And still is it seems! :)

Fact is, something needs to be done. I hangup on calls all the time with my cheek.

SO ANNOYING and NOT professional (I have a work iP4 and personal iP4).

Why not just press home button, then power button?
 
I've had my iP4 for about a month now and I keep unknowingly muting my phone with my cheek... VERY annoying. At this point, I'm expecting my girlfriend to get me a Samsung flip-phone for Christmas, since her's does not have this problem.

I checked my serial# and my hardware is recent, 40th week of 2010.

Is it worth getting Apple to swap it for another one? Or is this just a part of life with the iPhone4?
 
My wife has had this problem since day one. Face mutes/ends calls/speakerphone by cheek... Got it replaced with a new one from the Apple Store and it still happens! "Part of life with the iphone4" I guess.
 
Replace it until it works. Most people have never had this problem. Get a good one and forget about work-arounds. :apple:
 
I have a week 40 iphone that came with ios 4.1. I had proximity sensor issues from day one. It was pretty bad. I made a genius appointment, but they did not fix it. They told me I could return it, but I decided to wait for the next update. I updated to 4.2.1 and it fixed it. The screen has not come on during a call since.
 
I Never had that issue. How are you holding your phone. Go to the apple store and get a new one there must be a problem with your sensor.
 
This is a widely known iPhone 4 issue. They may have fixed it later on in production but a bunch of early adopters have an issue with it. My friend either mute's the phone or it gets put on hold every time I talk to him. I don't know why he hasn't updated to 4.2.1 yet.
