Certain NFC tags cause NFC to stop working
This is normal1 behavior. The Android NFC stack is known to die when the communication with tags is interrupted during certain communication phases. So what you are experiencing is a poor transmission between the phone and the tag. In those cases where the communication between the phone and the tag drops in the "wrong" moment, the NFC service dies and you have to manually restart it by disabling &amp; re-enabling NFC from the settings app.





1) Read "normal" as "you have to accept that things are like this" but not as "this is intended/bugfree behavior".
