thanks.

1. Unlock worked several times as it is necessary but after ceased, although the sound was as successful at reading the ring. At the same time in the system menu appeared yellow triangle. But I was able to unlock the phone only after rebooting the phone by system power combination.
   This yellow triangle - authorization error in Google. Telephone why then forgot my password, this has never happened. I do not know what the cause of it all, but very uncomfortable to deal with such a problem, especially when the in the phone non-removable battery.

Xperia T (LT30p)

2. Second question - what happens if NFC service turn off before turning off a phone ? whether it will be forcibly turned on?

3. Third problem - a long time i couldn't login for this site, password recovery says what i not registered. and i was registered 2nd time for this email, but now it my old account on the same email)

4. small note - when lock option enabled firstly, the screenlock starts to work only after the second turn off the screen.

5. just noticed - after setting up blocker - all entries in the ring disappeared. I remember both sides of the ring menu "Manage keys"

1. Press "Create" always make doubleckick - it open a twitter settings.

2. If NFC service is off, I get the 2 identical alert for every action in the menu. "NFC functionality is not working.."

3. On Xperia T unlocking screen working normal, but:
   First time i enable option "enable nfc ring unlock wiget", ping it to desktop, make enable, and.. can't unlock my fone. Absolutely. I restart my phone few times and desktop was loaded early that lock wiget, otherwise would have to flash the phone.
   Without this option unlocking work fine.

4. Unlock don't work if screen turn off. I need press power, scroll my screen logo and after that a see NFC logo. Very long and not convenient. (I disabled native android screen lock, all ok).

5. The menu is really not very clear. need 2 checkbox - "I want to unlock the phone by ring" and "I want anything" and, separately, the advanced settings.

6. About app "NFC Ring Control": please add into "create" menu new options like skype, ICQ, etc. Of course it can be added in Text.

this until all my experiences for 10 minutes of work. and forgive the clumsy English)
