DroidGuard is particularly relevant nowadays (article from 2019) given that Google is using it to implement hardware-backed attestations (i.e. using device TEE) of device integrity.<p>Current cat-and-mouse game is to spoof props to a device that doesn't support hardware attestation, but Google is somehow able to detect props used for spoofing (as opposed to using the actual device with those profs) and bans them.<p>Once Google decides that enough devices support hardware attestation and they get rid of software attestation, even unlocking the bootloader will trip it and you won't be able to use apps that request this level, and this level is impossible (barring exploits) to spoof.
