Cannot slide to answer phone calls

I started this thread with iphone 4 iOS 4.2.1 when I had these problems. I havent had them since i upgraded to 4.3.3. And even then i thought that maybe it was iOS memory problems with too many apps in memory. I found out later that if i quit some apps i didnt get the problem for longer periods of time.

BUT i havent had this problem now since iOS 4.3.3 , 4.3.5 nor 5.0.1 (on same iphone 4) which I have had. I dont know if its because i now and then shut down apps from memory so that I have more free memory available.

Same problem here. Since I had the 1st gen iPhone. Happened with every model and every iOS version. It’s very annoying. Also I happen to pay most of the calls since I technically have to call back on every third incoming call.

It’s a shame Apple won’t address or fix it. It’s frustrating.

Same problem here; iphone 3gs, latest iOS. Needless to elaborate on the nuissance this causes.

@habi, I like the idea that this might be a memory issue. I am almost at the limit of my phone's capacity, so perhaps it plays a role. Will keep an eye on it if closing the 'multitasking' apps will help resolve this. However, I remember a friend who had a 3g model back when we did not even dare dream about multitasking on the iphone and he had the same issue (not sure if his memory capacity was at limit or not).

glonk,

I have the problem on both my iPhones, 1 3G and 1 4S.

I tried to delete many of my applications, as a test.

On the 3G, ths did not make a difference.

On the 4S, this improved things. I can now answer about half the calls I recieve on my 4S.

So, it seems related, but not completely.

The problem is still completely gone while I am charging my iPhones, so it must be related to that too.

Needless to elaborate...

I've had this on my 4 and 4S - from iOS 4.0 to 5.1.1.

Can't say I remember seeing this on my 3GS.

Exactly as mentioned before, it's when its in my pocket. Doesn't matter whether I have a screen protector or not.

I'll be trying iOS 6 soon in the hope of a resolution.

I have this on my 3GS and my 4S.

I moved to iOS6 and it seems to be even worse now. I can answer only about 40% of the calls. Luckily I do most things via mail...

I see the amount of problems growing:

- I can't really use my iPhone as a phone due to this problem

- Every time it upgrades the software, it loses its internet settings, so I mostly run with my phone without internet for about a month.

- I often have problems of SMSs not arriving

- Over 50% of MMSs don't arrive. I've tried many things, but to no avail.

So, _all_ the basic functionality on the iPhone is not working well, for both my iPhone versions.

Many of my friends see the same thing.

I really don't understand that Apple just does not respond to this, does not seem to care.

To me it's clear. My next mobile won't be an iPhone...

@wontergg

Try www.unlockit.co.nz to restore your APN which is probably what breaks every software update and may have to do with your MMSes not arriving.

APN is indeed what breaks every software update.

Next time, I'll get it repaired faster, I guess...

Filling in APN does not solve MMSs. I've tried everything and gave up. This problem in this ticket is a way higher priority for me, and I'm still trying something once in a while...

Thanks!

Yep. This is driving me nuts too. I'm considering a non-Apple alternative handset.

I have the same problem:

Handset: iPhone 4S

iOS 6.0, AT&T

Bluetooth off

Not using a headset.

When I get income phone calls, I sometimes can't slide the answer/unlock.. I keep trying and sometimes it works after awhile.

Very annoying.

Does anyone have a workaround? Not following the discussion below on APN.

Hey Steve,

I have been studying this for a long time. Including this thread.

The only workaround that works for me is when I connect the charger.

So, when I'm at my desk and know I will receive a call, I connect the charger, and then I don't have the problem.

(and I fully realize that this is only very partly helpfull...)

Thanks wontergg -- I'll try that.

This problem doesn't happen to me consistently.. but when it does it sure is annoying.

Like others, every iPhone I've ever owned has done this btw.

Sometimes I think that the iPhone is awesome for everything except being a phone. 😁

@wontergg Interesting, but that won't help me as it only occurs when my phone's in my pocket.

Yep!

Steve, interesting that you mention it, as I also know some people who don't have the problem.

Now, what I did when I bought my 4S, is to copy the configuration from my old iPhone.

Did you do that too?

Maybe we should try to "reformat" our iPhone.

I tried the restore function that is in iTunes, but that does bring some configuration. And it does not solve the pb.

Anyone knows if it is possible to completely erase all configuration?

Did anyone ever try this?

Settings > General > Reset > Erase All Content and Settings

Never tried it and don't intend on doing so.
