Hi all,

I have XA2 and XA2 Ultra running, and I noticed this: If I restart my XA2, NFC is re-enabled after reboot (at least when Bluetooth is enabled, but I'm pretty sure the same thing happens with both Bluetooth and NFC disabled). For some reason, my XA2 Ultra does not do this; it remembers the state.

The only difference besides XA2/XA2U is that XA2 was flashed with 3.0.3, whereas XA2U was flashed with 3.0.1 (I think) and then upgraded.

Could someone test this? It's quite quick to do ;)

What about XA2 Plus?

Can confirm on XA2 Plus also does this on which i flashed to. Guess that's another thing to keep mind of.

As @slava suggested in comments of the question, the folder /var/lib/nfcd/ was owned by root, so I changed the owner to nfc:nfc. In addition there was no settings file in that directory, so I created an empty file of that name, changed the owner, toggled NFC off and the file now contains the setting:


NFC now stays off when I just rebooted the device.

Sailors, could you also have a look at this? Thanks!

Edit: brainfart fix in settings content.

So to make it easy to check; this is correct:

[root@Sailfish nemo]# ls -la /var/lib/nfcd/
total 12
drwx------  2 nfc  nfc  4096 2019-07-03 15:38 .
drwxr-xr-x 33 root root 4096 2019-05-01 15:26 ..
-rw-------  1 nfc  nfc    25 2019-07-03 15:38 settings

It's weird. For me, installing nfcd package changes ownership of /var/lib/nfcd directory to nfc:nfc according to %dir %attr(700,nfc,nfc) in the spec file:


slava ( 2019-07-13 18:18:52 +0200 )edit

Then I suspect that the permissions are wrong in the flashed image file instead... I didn't try reinstalling nfcd package.

Thanks, worked fine for my Xperia 10.

Seems fixed after 3.1.0 update atleast for me. Tested when I saw @Direc 's qestion. 17B vendor binaries. Can't recall flashed version. Have to check that later.

Edit 2019-08-02 Definetly flashed 3.0.2. Command: devel-su tune2fs -l /dev/sailfish/root | grep 'Filesystem created' gives Filesystem created: Mon May 6 15:25:48 2019. Remeber that flash script didn't let use 16 binaries.

Fixed for me with 3.2.0 EA upgrade. Was too lazy to do the woraround.

XA2 plus with NFC automatically turns on after reboot.

zuyev ( 2019-11-13 16:41:22 +0200 )edit

FYI, this also affects my newly flashed Xperia 10 wlth Torronsuo I can turn off NFC for a session, but it is always reenabled after a reboot.

I'm bumping this as I have the same problem on Xperia 10 with latest release The problem doesn't occur anymore on XA2 Plus, but on X10 it still does.

There is no settings file in /var/lib/nfcd/, and the nfcd directory is owned by radio:radio and have no permissions for others drwx------

you can create empty file with touch /var/lib/nfcd/settings and you can change ownership with chown nfc:nfc ... both require devel-su

Try to see the accepted answer for help, perhaps the issue is the same for you...

As for a proper fix; this issue is still "Tracked by Jolla" so it isn't fixed yet.
