Hi Michal,
The MIFARE Ultralight and the MIFARE Classic uses ISO/IEC 14443-3 protocol (the “-3” is important). This means, if an error occurs or an invalid key was used, the card goes into internal HALT state and terminate any communication. But this should not shutdown the whole NFC communication on your device! Here you must remove the card from reader (this will reset the card) and put into the field again.
For me it seems that this is an issue in the middleware. Can you check your software on a different device (a different manufacturer)? If both devices behaves different you can identify this as firmware issue. As Android developer you should test your software on so many different devices as possible to prevent device specific issues.
