Android "Your Device is Corrupted and Cannot be Trusted..." Message

[Grubstake]

Hello.  I have Malwarebytes Premium as well as McAfee on my Android Sony Xperia phone.  Spontaneously my device went black, then showed the "Sony" logo it usually shows at the beginning of a reboot, then showed a black screen with red message stating "Your device is corrupted and cannot be trusted and may not work properly", then continued with rebooting and continued to boot up on it's own, apparently as normal.  I immediately ran scans using Malwarebytes Premium as well as McAfee and both said the phone is clean.  Can you help me understand if there is a real threat associated with this message and what I should do next?  Thank you.

Hi @Grubstake,

Is your phone rooted, or have you used a custom ROM?  I found this article addressing the error you are getting: https://thedroidguy.com/pixel-device-corrupt-cant-trusted-may-not-work-properly-error-issues-1076400

Seems more like corruption in the OS then malware.

Hello Nathan,

Thank you.  No, I have not rooted my phone or used a custom ROM. I haven't tinkered with anything on the phone; I just use it as it came from the factory and only install Google Play apps. My biggest concern is that somehow, malware or something from the internet has caused it to be rooted, is that possible?

Thank you.

Hi again,

Also, thank you for the article link.  I found that one as well, but it has raised my concerns that this error message seems to be for rooted phones, and since I didn't root my phone, maybe someone else did remotely.  Also, my phone has never been out of my supervision, in the hands of anyone else or anything like that.

Thank you again.
