Severe system bugs on iPad 6th Gen (A1954) running iPadOS 17.7.8

Hi everyone,

I’m using an iPad 6th generation (A1954 – Wi-Fi + Cellular, 128GB) with iPadOS 17.7.8, and I’m experiencing several critical bugs that persist even after a DFU restore:

- Lock screen doesn't work (button responds, but screen won't turn off)

- Apps crash or fail to respond

- Can’t delete apps or widgets from the home screen (only through Settings)

- iPad restarts automatically after installing some apps

- Some permission-related errors inside apps

I've already tried:

- Full DFU restore via Finder (Mac) and iTunes (Windows)

- Setting up as new iPad (no backup restored)

- Ensuring no profile or MDM installed

Touch ID is disabled due to a screen replacement, but the button works for navigation.

Has anyone experienced similar issues? Could this be related to the missing Touch ID, or is it a software bug in 17.7.8?

Thanks in advance for any help or confirmation.

iPad, iPadOS 17

As described, your iPad has received a third-party screen "repair". Unless repaired by Apple, or an Apple Authorised Service Provider (AASP), a screen repair will result in TouchID (or FaceID for iPads Pro) being disabled by default. After repair, your iPad's biometric authentication can only be reactivated using special software that has only been available within Apple's authorised repair agents.

Given that your iPad has not been properly repaired, it is very likely that other faults or issues exist - and for this reason you may experience difficulties as described. Be aware that if presented to Apple or an AASP, or is remotely tested by Apple, the third-party repair will be detected - at which point Apple will likely decline to offer assistance; Apple will not attempt to correct a failed third-party repair.

Sorry, but other than returning to whoever previously repaired your iPad, you are very likely to be on your own...

Why does do so many users think that a problem with their device must be a bug? Bugs affect most or all users, and a REAL bug will result in thousands of reports.

Your symptoms sound like multiple hardware failures. Contact Apple support. Best way:

Install the Apple Support app on your iPhone or iPad - you can contact support directly from the app, and the tech will have (with your permission) access to diagnostic data on your device

Other options:

- Click on “Support” at the top or bottom of this page
- Go to Contact Official Apple Support

(Note that both of the above have options to receive a callback or chat)

- Call Apple Support; the phone numbers are in this link→Contact Apple for support and service - Apple Support
- Make a Genius Bar appointment at an Apple Store→Genius Bar Reservation and Apple Support Options - Apple
- Find an Apple store or Apple partner service provider→Find Locations

The original iPad screen (and OEM replacements) are uniquely calibrated and coded during manufacture - and when installed in the iPad is "integrated" using Apple-proprietary software to ensure that it both works properly and shows consistent colour.

The TouchID sensor incorporated within the Top button is a security component that combines with the iPad's security chip (the Secure Enclave). As a security measure, if the iPad detects tampering or presence of non-OEM (third-party) components, will intentionally disable the TouchID sensor within which your biometric data is securely stored. With TouchID intentionally disabled by the system, other functions may not operate as expected.

The behaviour that you observe is not a fault or bug, but is a consequence of the third-party repair.

Hi LotusPilot, thanks for your reply.

It's interesting to know that screen replacements can affect support and authentication systems like Touch ID, as you mentioned.

However, in my case, the screen is working perfectly — multitouch, gestures, palm rejection, and even Apple Pencil support. Everything works fine.

Where I live, there's no access to official Apple Stores or Authorized Service Providers (AASP), so half the country is left without official support. That's why I'm reaching out here.

The issues I described are very real and persist even after a clean DFU restore. I'm considering recording a screen capture to better show how the bugs behave in real time.

One thing I didn’t mention before (because I know it also depends on the case itself) is that the auto-lock with the magnetic case lid might not be working — but again, the screen and hardware are responsive.

- The lock button works physically

- Pressing it triggers the shutdown menu

- Pressing it + Home takes a screenshot

- It also powers the device on

But it won’t lock the screen — the screen simply remains on after the button press.

So, this seems to go deeper than a screen swap — and that’s what I’m trying to understand.

Thanks again for your time.

Hi Lawrence,

Thanks for your reply.

Just to clarify, I’m not a technician — I’m a regular user reaching out here because contacting Apple Support isn’t an option in my situation. If it were, I would’ve already done that.

As I mentioned, the core issue is that several apps — including the Apple Support app itself — become unresponsive when permission modals appear. For example:

- When a permission popup appears, clicking “Continue” lights up the button, but nothing happens.

- The animation triggers, but the action behind the button is ignored, and the modal stays stuck.

- I’m forced to close the app — there's no way to proceed.

So yes, I’m trying to get community feedback or insights because even a clean DFU restore did not fix this. Any help or shared experiences are appreciated.

Thanks again.
