Hello,

I have noticed this issue only a few times, however I am wondering if anyone else is experiencing the same issue. When my phone has been locked and I get a call I am unable to slide to answer the incoming call. It is as if my touch screen is not working. I do not have a screen protector on it. If I press one of the side buttons then try to slide to answer it will work. Anyone else having this issue? I am hoping that it is a software bug. Thanks!
 
Interesting. Back in October '13 to September '14 I used an iPhone 4s, 5, and 5c all on iOS 7.0.x - 7.1.2 and I had that same thing happen on all of them. Definitely not hardware. It's almost like the digitizer didn't even wake up until I locked it or hit a key. It was intermittent though, but it does happen.

Recently my mom has been complaining of the same thing (iPhone 5 on 8.1.2) but she's had it happen as far back as 7.0. I don't remember this happening in iOS 6 though. So it's something since iOS 7.

Anyone else? I'm not an active iPhone user, but I keep a 4s as a spare and use it a decent bit, just not as an active phone.
 
i have the same issue. happened a couple of times on my 6 so far. had the same issue when i was using a 5. wondering if its a software bug. not too big of a deal since pushing the volume button then sliding to answer works, or i can use my pebble to answer the call
 
It's happened to me on my iphone 6. Good to know that I can hit the volume button then unlock.
 
AH! I thought I was the only one with this issue. Happened to me a couple of times. Glad to know a work around using the buttons.

I just used to restart my phone to fix the problem.

Using a 6 on iOS 8.1.2.
 
This is really not an issue; i noticed you can only decline the call whilst using the phone i.e unlocked. However in locked mode pressing the power button twice cancels the call if you intend to ignore it!

I have been facing same issue i.e., when screen is off and received a call "Slide to Answer" doesn't work even after trying to slide. Mine is iPhone 6s Plus 64GB running latest iOS 9.3.2. There is no screen protector nor screen dirty enough not to recognize touch events.

It isn't a consistent issue to reproduce always, and happens only once in a while. Today it happened again, and couldn't answer the call due to this issue.

We have another device recently bought iPhone 5s running iOS 9.3.2 and showing similar issue once in a while. On this device also, issue isn't consistent and happens once in a while. There is no screen protector nor screen is dirty enough not to recognize touch events.

It appears digitizer isn't awake though device is awake and screen is lit, and causing touch events not registered. Appears to be a corner case power management issue in iOS? Anyone else having this issue recently?
 
I've been having this problem with iPhones 4, 5, 5s, 6 and 7. It happens on about 50% of my calls.
Are you setting up those phones from a backup? Although even with that I can't imagine it getting in the way. Given that so many phones have been showing the same thing with you, and to such a high frequency, it sounds like the issue would be elsewhere than hardware or even software.

Yes, they all have been activated from back-ups. Maybe something is being carried through.
 
I'm experiencing the same issue (sometimes) on my 6s iOS 10.1.1. Glad to know the possible solution by playing with volume buttons. I found if we restart our phone once a week, it could fix such small issues.
