Touch IC ios 11 error
Hi all! First, thank you for being there for all us repairshops all over the world!
My issue is - i work in a repairshop and we do a lot of iphone repair among others. I've been using a semi original screen for the repairs i've done - original LCD and Digitizer, the rest is high copy. There has never been issues with these screens ever since iphone 6s arrived on the market. But, they all have unoriginal Touch-IC on them (on the screen, if unoriginal, it'll be all blank) and again, they always worked fine for us.
Now, a few days ago Apple released IOS 11 - and since then, i've had 2 phones who, between 30 seconds to 1 minute after updating to IOS 11, lost touch completely. I've had 10 different screens on them, none working in touch - but if i take a broken original screen and plug it on, everything works just fine. DFU restore does not help, maybe momentarily, but touch will stop working again within short time.
I've been asking colleagues and others if they experinced anything like that, but none have, because IOS 11 has only been around for a few days, and no one wants to update right away. It's just weird that 2 phones in 2 days have done the same. It is as if they bumped up the voltage in the screen by just a little bit in the IOS, so the unoriginal IC's will fail. Maybe i'm just going crazy and seeing conspiracys, so any one who experienced anything like this, please come forward :)
The same issue was on LG nexus 5x, however this was an error in the production and an inferior NAND that could not stand the tiny bump up in the voltage during the update, and LG swapped boards under warranty - but this is not the same situation, i'm just saying it's been seen before :)
Sorry for my absence - and thank you for all your contributions! It seems that good guy Apple (irony may occur) have solved this one for us on IOS 11.0.3. If your or your customers phone decide to throw touch, force update to 11.0.3, and all should be good. This is only regarding iphone 6S, none other. The other models/cases in this thread are sadly mostly results of faulty screen or an error made by the technician :)
But, we have another problem facing us: iphone 7/7+ - if you are so unlucky to break your homebutton or sensor flex, your phone will not boot, it will just stay at the apple logo. You simply cannot just go changing them with aftermarket parts or OEM parts, it must be fully original (not chinese-original), which means 1. much, much harder to get, 2. much, much more expensive. This does, however, not effect screens, you can easily use the high copy grade - as long as the small parts are ORIGINAL! So, fair warning my friends, be very careful not to bust anything when taking the screens apart. Basically, Apple reinstated error code 53, but not as an itunes error, more as a phone that'll brick when booting. If you switch to original parts, it boots just fine again. Apple has not yet solved this in the latest update like they did touch-ic error on iphone 6S, and who knows if they will at all. Back in the day, they got convicted into removing error 53 (if you had aftermarket homebutton installed on ip6, your phone would brick on updating in itunes, until original button was mounted), as it was a violation of consumer rights, as Apple was making it possible, only for Apple to fix it. We are facing the same problem here, basically - and as i see it, there are 2 solutions: Apple will have to change this (as this haven't been a problem the since ip7/7+ release, but is a new thing in thread with ios 11), or we be very careful, and buy original parts when we mess up. My personal opinion: get a lawsuit going, so we get the possibility and freedom of using the parts we want (and the customers want in most cases, as it is much cheaper for them as well), back!
