systemless-host breaks nfc on MIUI 14.0.8.0 Poco F3

[ThiagoMC40]

Hi. This is my first time using github so I'm not sure if I'm addressing this properly, but I noticed that after flashing this module with kernelSU (0.7.1 - 11366) the NFC stops working on the Poco F3. It can't be enabled and when you test it on CIT NFC Test, it says "NFC is not available".

Removing this module fixed the problem.

Such an error has not been reported before. Could you try disabling the module instead of removing it?

[ThiagoMC40]

Just tested it and after disabling the module and rebooting, NFC works fine again.

I tried this with other modules installed and also with systemless host as the only one. Neither worked as intended. NFC always breaks for some reason.

Is it fixed?

@symbuzzer Here is an exception stack trace about the same bug happening on Redmi Note 11T Pro. Hope this would help.

I think it could be a duplicate of #5.

This error message you're encountering indicates that the class com.android.nfc.NfcService$NxpNfcAdapterService could not be found during runtime, leading to a NoClassDefFoundError.

It is not possible to see the error from this log. Maybe the hosts file you are using is causing a problem. Just install the module and try it without activating any ad blocking applications.

Tried but still not works 😕

I really dont know what causes this issue. I see it only MIUI based roms

[rsp4jack]

I unpacked com.android.nfc in my ROM, and com.android.nfc.NfcService$NxpNfcAdapterService is right there. Really confused

I think your KSU doesn't umount at all, especially if your kernel is non-GKI. Try it with ZygiskNext + Shamiko. More than likely MIUI has root checks somewhere. @symbuzzer I don't think this issue is within the scope of this module.
