You have to give more info then that else it would become a guessing game. Can you share your blocks with us and tell us on which phones it works and on which phones it doesn't work? Especially android versions are important.

The app screen must make a QR Code of the players notes.

I am currently using Huawei but on my new phone Samsung it does not work.

I have another app with same blocks for the QR code and that app works perfect
