Hello,
There is two way of reading NDEF messages with Android: native reading (reading without application) and reading with dedicated application.
You have to be aware that android version < 9.0 does not support native reading with tags with memory larger that 8kbits. Android >= 9.0 supports native reading of tag with any memory size.
With dedicted application, there is not this limit, whatever android version. That's why you are able to read/write the ndef message with the ST25Tapp app.
It should work also with other applications, assuming they write or understand the correct CCFile.
For CC File formating on ST25DV, I recommand you to read the following aplication note (AN4911), where everything is explained: https://www.st.com/resource/en/application_note/dm00328901-ndef-management-with-st25dvxxx-and-st25tvxxx-products-stmicroelectronics.pdf
Best regards.
