My perfect NFC Ring Setup (Nexus 5, Android 4.4.3, rooted, encrypted)



  • It took me more then 8 hours to find my perfect NFC ring setup. I share this with you and hope, that it will save you some time.

    Instead of NFC Ring Control I use NFC Tools (https://play.google.com/store/apps/details?id=com.wakdev.wdnfc).

    Language selection does not work in NFC Ring Control. I switched to German and it worked. The next time I started the NFC Ring Control app, the language displayed was English again, but in settings German was selected.

    NFC Tools provide more information about the NFC tags on the ring. I found out, that each tag can store 137 bytes. With NFC Tools I wrote a VCARD to the black tag, because this is the tag, I keep on the top side of the ring. First I left the white tag empty, but when I used the tag to unlock my phone, a popup was displayed, that a new NFC tag has been detected. So I filled the white tag with an app link to start my current launcher.

    Instead of NFC Ring Unlock I use NFC LockscreenOff (http://repo.xposed.info/module/pk.qwerty12.nfclockscreenoffenabler)

    My Nexus 5 is encrypted. On encrypted phones it is not possible to disable the stock lock screen (it took me a couple of hours to figure that out).

    With NFC Ring Unlock I had two lock screens then. First I had to unlock the stock lock screen, then I could unlock the NFC lock screen. With the Keyguarddisabler (http://repo.xposed.info/module/com.lr.keyguarddisabler) of the Xposed Framework (http://repo.xposed.info/module/de.robv.android.xposed.installer) the stock lock screen is displayed only once after reboot, which made the NFC Ring Unlock the only lock screen. Problem solved? Not really. When I turned the screen on, first the current app is displayed and it takes a while till the NFC Ring Unlock app is displayed. The NFC Ring Unlock lock screen has no widgets, so to start the camera I have to unlock the phone and start the app. With the stock lock screen, I can start the camera directly. I removed both the Keyguarddisabler and NFC Ring Unlock.

    Finally I found the NFC LockscreenOff module of Xposed. This adds the missing NFC tag unlock function to the stock lock screen. Its features are quite similar to NFC Ring Unlock.

    Now I am really satisfied with my setup. I love my NFC ring, it's very usefull and cool show off.

    Thanks for sharing @Hannes-Dorn

    "Language selection does not work in NFC Ring Control. I switched to German and it worked. The next time I started the NFC Ring Control app, the language displayed was English again, but in settings German was selected." -- Can someone please confirm this? This works fine for me on latest beta release. @Hannes-Dorn can you please sign up for the beta program and see if that fixes your issue?

    RE Providing more information, we could probably work to do this, I will look into a way we can enable an "Advanced mode" or something however let's face it, if yuo are technically minded you will know to use the NXP Taginfo app which is the most verbose app. NFC Ring Control focuses more on usability (heatmap/i18n/simple UI etc).

    Good to know RE encrypted phones, thanks!
