Warning

• PayLib-release-xxx.aar package: This is a package which must be used carefully. Only use it to disable the Android Nav Bar, not for any other function (for example, payment functions). In case you have any doubts please reach out to the PayXpert teams.

• If merchant app/integrator disables the navigation bar, they will need to implement a functionality that will allow it to be activated temporarily. Otherwise, the terminal will be blocked in case there is a manual intervention that needs to be done on the device.

• The variable to deactivate the Nav Bar via SUNMI is shared between merchant app and PayXpress app.

• By Default, PayXpress app deployed in the P2 LITE SE / P2 PRO devices will activate the Nav Bar in the standby screen (initial screen) and then it will disable it during the payment transaction. Once the payment has been finalized it will be reactivated automatically.
