Removing "Your device is loading a different operating system"

CoffeeTime03

I flashed GrapheneOS on my Google Pixel 6a and every time I reboot, I get a "Your device is loading a different operating system" with the id of said operating system.
It does that before going into the OS's splash screen.
Is there any way to disable it and go straight to GrapheneOS as Auditor can already check everything (as far as I understood)?

CoffeeTime03 unfortunately not this is hardcoded in firmware please read and familiarise yourself with the following:

Get Google to whitelist the project.

That should be documented in the install doc. I'm sure it confuses a lot of people who think the install failed

Why would they think that?

I would think that it succeeded.

Craig_L It is in the install doc: https://grapheneos.org/install/web#verified-boot-key-hash

Craig_L

regardless, it should be part of the doc.
If I wanted to be familiar with Android doc as MetropleX suggests,
I would be a developer, not an end user.

Agree here. Would be nice to document.

Craig_L

Exhort14 yes you are right. But it is buried in tech speak. I suggest there should be a short paragraph
saying expect to get this screen & msg. That means the install was successful.
For details, read the following.

Craig_L Agreed.

And while I personally think the current information is pretty straightforward, it may not be as simple for the lesser technologically adept users.

Craig_L That means the install was successful.

I think an image showing this behaviour would be a good idea.

I have come across a few people that I know got confused with this. @Craig_L has a point in my humble opinion.

It's also not accessible. I'm legally blind, and the print of this boot warning is too tiny. It just adds another step. I also wanted to set up a tablet for an elderly friend using Graphene in "kiosk" mode, but now I have to figure out how to help her bypass this screen if the battery ever dies. That's terrible. Big Tech (Google included) hardly ever things about a11y. Shaming consumers into using their OS even though we purchased the hardware outright seems to be the MO here. (Even Sony mirrorless cameras now complain about 3rd party batteries, even though Sony doesn't even sell OEM adaptors for use with external power supplies.) And Google will simply say that they don't have to make installing / booting a 3rd party OS accessible. And with the current U.S. administration, sadly, they are correct, and meanwhile, they have over half the nation convinced there is too much regulation.

I don't have a Tablet, but on the phones there is no need to do anything about the different-OS screen except to wait a few seconds for it to go away.

Here I'm not following. Which nation? Are phones from other companies better? Do EU regulators mandate minimum font size for the bootloader?

Something can be non-ideal without being deliberately nasty. And if Google is currently offering the best deal in terms of secure phones supporting third-party operating systems (personally I think so) then arguably criticizing other companies would make more sense than criticizing Google?
