Can you please specify which ST25 NFC Tap from ST Microelectronics mobile app are you using : Android or iOS ?

Waiting feedback to clarify.

OS is Android. But we are able to use this app in M24LR04E-R.

​Hello

The context is more clear.

Which version of Android are you using?

Your issue (or behavior)  is probably due to the memory size M24LR64 vs M24LR04. Depending of Android version, two bytes @ for extended memory is not correctly supported.  Are you able to upgrade android version to 8 or 9 ?
