NFC not found on Samsung SM-J500FN (LineageOS 15.1 build j54)

[cryptax]

Hi,

Since I have installed LineageOS 15.1 on my smartphone (Samsung SM-J500FN), NFC does not work. More exactly, NFC does not even exist.

adb shell service list | grep nfc does not show any NFC service (though I should have seen here something like nfc: [android.nfc.INfcAdapter].

I used this build: lineage-15.1_j54_20180726_NIGHTLY-j5nlte. I see some additions to NFC in the change log of lineage-15.1-j58-20180903. Is it in a working state now?

Thanks!

I've tried with a newer ROM: LineageOS 16.0 - j5-20190102. Unfortunately, there is still no NFC service.

$ service list | grep nfc
j5nltexx:/ $

Help please :)

Hi @cryptax,

The NFC support has only one commit:
12d4d36#diff-88dc16df0c22cd28f42995ae96d113a8

So I think it's never been tested. The code should be compared with a similar model to fix the problem here.

For information, here is its NFC config in kernel:

# CONFIG_NFC is not set
CONFIG_NFC_QNCI=y
# CONFIG_NFC_NQ is not set
CONFIG_NFC_PN547=y
CONFIG_NFC_PN547_8916_USE_BBCLK2=y
# CONFIG_NFC_PN547_8916_CLK_CTL is not set
CONFIG_NFC_PN547_USE_EXTERNAL_LDO_VIO=y
# CONFIG_NFC_PN547_LDO_CONTROL is not set
# CONFIG_NFC_PN547_PVDD_EN_CONTROL is not set
# CONFIG_ESE_P61 is not set
# CONFIG_NFC_PN547_ESE_SUPPORT is not set
# CONFIG_SEC_NFC_I2C is not set
# CONFIG_SEC_NFC is not set
# CONFIG_ESE_P3 is not set
# CONFIG_SEC_NFC_IO_EN is not set
# CONFIG_BCM2079X_NFC_I2C is not set

So that I can compare, do you know of a smartphone under lineageOS with functional NFC PN547?

@vince2678, Have you started to separate NFC without being finished? Has NFC ever been functional here?

Thanks.

Unfortunately no :( But if I find one, will add to this response.

The problem must always be present on an updated version but can you test it?

I'll test next time I update. I lose some of my settings when I use a new version, so I'm not testing immediately as this should not fix the NFC issue.

Any updates on the issue ?
