Moto Edge40Pro - short message upon boot

[DTTR]

Hello,

I'm interested in a Moto Edge40Pro.
The issue is that when it boots, there is a short time message displayed on the screen.

"Injected device".

Does anyone know what can that be?

The device appears as genuine when tested with AIDA, with the official Moto tool, the banking apps work, the Google wallet works, the security updates are current (1st of September).

Thanks,
D.
