2022-03-01 12:00:18.604 2515-2910/? I/VolteServiceModule: onSreenOnOffChanged: on =0
Not sure why the error is post we get the packet in “nfc_data_callback”.
I am not very much familiar with the underlying services , but I believe it has something to do with
"SecureElement::getInstance().isPeerInListenMode()) " statement as the same tag I can write with other devices.
Any help will be much appriciated
