Hello.
I have z5 compact e5823 (2 weeks out of the box), which show me no action when i'm trying to connect it to SBH52 or all other NFC tags. NFC is enabled, but i don't see NFC icon in status bar (maybe it should be?). NFC diagnostic test in "Support" is OK, but smartphone can not read any tag or make a connection. Tried to reboot in safemode - no result. So, Android Pay is not working too - i touched pinpad in a market like a dummy. What can i try before asking for warranty service?
