Screen Glitches When Charged After Third-Party Replacement

I recently knocked my phone off a kitchen countertop onto a linoleum floor. The top of the screen would not respond to touch so it had to be replaced (third-party repair as it is a refurbished device). Unfortunately, the new screen glitches whenever the phone is charged, meaning the phone cannot be used while on charge. Thin horizontal lines appear, part of the bottom blacks out and the entire screen sometimes flickers on and off. This happens within either seconds or a couple of minutes of plugging in (it varies). At first I thought it was the cable, but an unused cable had the same issue. The new screen is an “Unknown Part”. I am using an iPhone 11 running iOS 26.6.

Thanks. I should probably be covered by the UK Consumer Rights Act, under unsatisfactory quality of service/product, so I can choose to repair it elsewhere.

Elsewhere, perhaps. But not by Apple at all. No one but Apple or actual Apple Authorized Service Providers have access to authentic Apple Screens. So anyone else you choose won't have one they can put on your phone and that means things just aren't likely ever going to be as it would have been with an authentic Apple Screen. Sadly, your phone has no trade value with Apple and it's resale value is pretty much none as well.


Since you already paid someone to replace the screen, I would take it back to them and insist they make the phone work at least better. Surely they offer some kind of warranty on their service or parts?

It (Unknown part) may get removed as soon as you get the Display replaced with a genuine one through an Apple Authorised Service center if there are no other issues with your device.



Display


Parts and service history

With iPhone 11 models and later, excluding iPhone SE (2nd and 3rd generation), using iOS 15.2 and later, you can go to Settings > General > About for the parts and service history of your iPhone. You can also find out if the display has been replaced. If the repair was done using genuine Apple parts and processes, "Genuine Apple Part" will appear next to Display.

 



  • An Unknown Part  message will appear if the display installation is incomplete or if the display:
  • Was replaced with a nongenuine display
  • Was already used or installed in another iPhone
  • Isn't functioning as expected

An additional message might appear that says "Apple has updated the device information for this iPhone." This means that Apple has updated the device information maintained for this iPhone for service needs, safety analysis, and to improve future products. 


These messages don't affect your ability to use your iPhone.

Check with an Apple Retail Store, not an Apple Authorized Service Provider. An Apple Store would replace the third party screen with an Apple screen, but there would be a charge for the part and labor, since they did not do the original repair/replacement. If you want a warranty claim on the defective screen, return to the repair service that installed the third party screen. Good luck.

Unfortunately, the third-party repair explains it all. Third-party repair shops do not have genuine parts nor the manuals to perform repairs, and thus why they are notorious for leading to more issues down the road. While your device was refurbished, depending on who refurbished it and what parts were used, you still may have been able to obtain service from Apple. However, that is now an impossibility since your device would be considered tampered with, thus nulling service and warranty.

Not arguing with you, but you also can't say with conviction an Apple Store WOULD be willing to replace the screen on their iPhone. I had a friend here who against my advice went to an iFixit type store to have their screen replaced and they took it to the Apple Store here (the very Apple Store you or I would go to), who flatly refused to touch the phone since it had been tampered with. One can certainly ask, but also not be surprised if they are turned down.

Sounds argumentative to me, but I’m OK with that. I was in an Apple Retail Store in Orlando several days ago, sitting at a Genius Bar table and watched an Apple Genius take an iPhone in for a battery replacement that had a third party battery.


Screens and batteries aren’t the same, agreed. However, tampering is a subjective term and a iPhone might be refused service if screws were stripped, adhesive leaking around edges of screen etc.


Your statement “But not by Apple at all” is something that can’t be said with conviction either.

You're right. I should be careful in saying not at all. In fact, we should both be careful in regards to speaking what we believe Apple may or may not be willing to do. They can ask. And Apple may or may not be willing to accommodate them.

Hello~ It doesn’t sound argumentative to me and was prefaced as not being so.


Your post does however make my next appointment with Apple most likely to be done in a more private area as I don’t want my discussion being so easily overheard. Yikes…that’s pretty scary.

Yes, and everyone should be made aware of all their options with Apple. Customer service is a complex area of retail. Those businesses that do well at it, like Apple, want to help their users, if at all possible. In retail, not everything is black and white. It’s management’s role to see shades of gray and do what’s best for all the parties involved.

Hi, there might be a private area in a smaller store, but at larger stores there are several large tables Apple users sit around and/or a long row of benches to sit at. Everyone hears everyone else’s issues. An Apple Authorized Service Provider might better be able to accommodate your needs.

Hello once more~ Yes, I am more than familiar with the Apple Stores and all of the local AASPs. First name basis with some and my experiences have been more private. Maybe I am just special …

You’re private counseling area, of course.

Hello~ Next time I go in will take some pics of the chair that they bring out from the back if I am not in my wheelchair. One of the wooden cubes is set up for a table and moved to an area removed from most store flow.


As you have stated many times Apple Store Managers and employees can be quite considerate to make sure one is made a repeat and happy customer.


Accessibility is taken quite seriously by Apple and I appreciate it personally.
