iOS 11 touch screen issues 6S

P.S : sorry for super long message haha cause I wanted to explain the whole story.

Also hope that this works for you :)

My phone had the same experience ever since I updated to iOS 11 to my iPhone 6 Plus in September. I had to buy a new phone however I still really wanted to use my old phone again since I have been using it for about nearly 3 years. It responds and then after a few minutes it doesn’t respond, then the cycle repeats itself. So I tried all I can for example buying new replacement screens looking at videos online, looking at post, reading comments from people who had the same thing that happen to me. However none of it worked. However about mid October (can’t rememberabout a few days after animal crossing on iOS came out) i finally been able to make it respond. I was fiddling with a ice pack since I’m from Australia and about this time of the year its extremely hot so yeah. Had my old phone along with my new phone with me when I was playing games on my new phone in bed. Was playing on both phones at the same time. Well my new phone I bought started to go hot so I applied the ice pack at the back of the phone. I then got really ****** at my old phone since I was playing animal crossing on it but it suddenly keep freezing. So...lol Idk what went wrong with me but I just decided to do the same with the old phone/ice pack. Then tried once again to play animal crossing on it,after

10 minutes or so but it when frozen on me again... so I finally got really **** ****** I turned it off and finally opened the phone up and reattached the screen connectors on again. Then put it back together and turned it on...well surprisingly it worked to my amazement, didn’t know the reason why it worked so I didn’t post this type of solution for people. However today I finally found the reason why the phone worked. The phone today went unresponsive again and the phone was super hot, (probably cause I was leaving it on a game and leaving it to run like that since it’s a auto game where I don’t need to control it and can still level up and another factor being today was like 3O something degree) so I once again tried to turn it off and reconnect the screen again however it still didn’t work did this like 3 times. During these time I notice phone went super hot every time I attempt to turn it back on. So I decided use the ice pack again. Before I did this I turned it off and reattached the screen again. Then applied the ice pack at the back of the phone for about 5 minutes and made sure the phone cooled down, phone kind of cold condition. Then turned the phone on again, and guess what the touch worked again. So what I think is just make sure that the phone is not ever super hot. Also the phone doesn’t always need to be done in these steps like everyday only when the phone is super hot or when you notice that touch is not working then try these steps.

Note: I’m not a professional so I don’t know if this would work for all phones just trying to help since it worked on my phone, but help this works for you guys

Same deal. iPhone 6 Plus. Original LCD, never been repaired, been protected and treated really well, yada yada.

Started having issues about three IOS 11 upgrades ago, so probably 11.0.x or 11.1. Didn't pay attention until I realised that something was seriously wrong and I'd been through an upgrade or two and the problem was still there.

The touch screen locks up randomly.

The touchscreen fires random keystrokes - just hovering a finger above the screen will fire a stream of garbage into a text message for example. Trying to touch a specific key on the keyboard will fire the wrong key or keys - before the finger gets to the keyboard the touchscreen has already chosen a different key.

In horror I watched the touchscreen scroll through my messages in Outlook - one every second or so, working its way down my inbox, marking each as read. For me read/unread is a primary marker of whether a client issue has been handled. By the time I noticed, and realised, what was happening, grabbed my phone from my desk, and closed outlook, I had about 1/2 day of detective work to do to get my erstwhile 'to-do' list back together.

Notice that the phone was laying flat on my desk - my hands nowhere near it - but unlocked with Outlook open (which is unusual for me - security is a concern) - and the touchscreen was still going haywire.

I spent, literally, 45 minutes trying to send a three sentence SMS. Required a lot of lock/unlock cycles (usually unfreezes the touchscreen). Then with the touchscreen firing a stream of garbage into the keyboard, and the keyboard auto-correcting that stream of garbage even as I tried to delete it, and then the touchscreen wholesale freezing every other millisecond, it just became impossible to get those three sentences in place and sent. Oh, and it was screwing with the recipient list even as I was trying to edit the message body. Incredible stuff.

Then there's the routine inability to even unlock the phone. Touchscreen freezes. Can't unlock iPhone. iPhone is a brick in a shiny case. Business day stops until iPhone wants to work again. Power off/Power on. Wait. Hope.

Idk but since you haven’t opened it up or did anything to the phone maybe you can bring it to apple and tell them the reason. Perhaps you may get lucky and they will give you a new replacement phone. I couldn’t do that cause I forgot about that and end up opening it to try to get the phone to work.

I'm having this issues, despite my iPhone 6S (128Gb) being a genuine Apple one (recently replaced with one of their own fresh replacements due to the 6S battery problem issue - mine was actually swelling up in the case!) - so I have had a completely fresh install either September or October, and started having problems in early November.

As soon as I upgraded to IOS 11.0.1 I started having problems, and they have continued! Today, for example, the screen has frozen multiple times, making the phone a brick. The OS is clearly running fine in the background, as I can close and re-open the phone (using a fingerprint) and double tap to get to the APP switcher... but the screen is dead. I'm currently on IOS 11.2.1. I am loath to try to go back to 10.3.3, if it is even still available, as I have various secure Apps (like banking apps) which need time consuming setup processes. But will, if it really makes all the difference!

Sometimes the screen works again in a few seconds, other times it can take minutes (even up to half an hour or more). If it is having a (longer) issue, I can hard shutdown (both buttons for 5s or more, and restart) the phone many times with no improvement... but eventually it does usually come back.

It seems totally random. I've had completely trouble free days, and whole days when I can hardly use my phone for 5 minutes without the problem occurring. I've tried removing reduce motion, turning off find the iphone, and removing and resetting passcodes and fingerprints.

I'm going to arrange a genius bar appt soon to try to see what they say.

Has anyone on this thread had any more info since mid December?

Hi,

I had this issue also with my ip6 64gb. I did replacement of my replaced screen with new OEM and thats helped a little bit. But since iOS 11.2 is out(i have beta test account) it working like a charm. I would propose to update your iOS, turn off locking the screen(somewhere I read that this is rootcause)...

Tomáš

Thanks Tomas,

However, I'm already running iOS 11.2.1, and have not found that any of the iOS 11 variants are much better than the others (I recall thinking that 11.0.3 was marginally better, but because the problems occur inconsistently, and I can occasionally have some days without occurrence, this may have been a wrong impression).

I will try turning off the lock screen, but this is a basic security feature and I would be quite unhappy if I had to live with the phone that way... and the problem is not a "lockscreen" issue... it occurs randomly (often in the middle of me doing something, using an app, or whenever)!

I'm at my wits end!

Hi David,

I understand. I was sooooo frustrated when this started to happen. At the moment, lucky me, this issue is fully out. What helped me for a while always was putting phone to DFU mode, downloading some files to phone in DFU mode and also trying to downgrade to iOS 10(even its not signed for ip6 anymore) and opening phone, disconneting baterry, disconeting all display conectors, putting them back and again connecting baterry....... that made it working for a while and now with last updates I have zero issues. Even response of system and baterry life is fine...

Tomáš

Thanks again, Tomas,

Wow... you are obviously more brave than me! I would be very uncertain about opening my phone and checking / unplugging the connections! I think it is unlikely these are an issue for me as (when the phone is working) everything is all very normal!

While I'm a mechanical engineer, I'm not a "technical" phone user. I prefer not to risk my investment doing something that might invalidate warranty, etc. Even doing things like entering DFU mode are a more than I'm very comfortable with, and I would only do that if an update had crashed (or something similar).

Regards,

David

I reported an bug! Here is the answer. Thanks Apple!

I have 6s and never opened and fixed. It’ has original lcd but still have this problems since I update my IOS. This Apple people make fool everybody

Just remembered, perhaps your iPhone 6S ison the very edge

of this issue:

iPhone 6s Program for Unexpected Shutdown Issues - Apple Support

and iOS 11 just put it over the edge.

The same problem after updating in iPhone 6s. How to fix that or when the official fixing will come?
