Google should bring Samsung’s Maintenance Mode to Pixel phones

I didn't know that Samsung had that feature, but it does sound nice - so long as you have the ability to enable maintenance mode.
I recently took my pixel 7 in to ubreakifix for a screen replacement. The screen was 100% dead, but I could still hear the notifications coming in. I couldn't put it into maintenance mode if it had one, so I think I'd still stress a bit about whether or not the phone would be wiped, such as in the case I was unable to verify the upload of a recent Aegis backup. It would be nice if the maintenance mode was able to be triggered via a web interface in cases such as mine. Or maybe even a specific button combo that would be difficult to accidentally do.

That's a good point, and I agree: There should be a way to trigger Maintenance Mode remotely, like through Find My Device, should Google implement this.

Good article, thanks for writing and sharing here!
I'm not an Android developer, but I do know Linux, and it sounds like Samsung's maintenance mode could just be another user with different permissions, with access to system directories but not user home directories.
If, as you say, Google gives the primary user full rights (like having admin rights in Windows), that would mean that Samsung might be creating "regular" users without those rights, and "maintenance mode" could simply be another regular user - by default, regular users don't have access to other regular user's home directories.

Theoretically, isn't maintenance mode completely useless?
If they're the manufacturer, they could upload and boot via fastboot a signed image that allows all tests to be done, all automatically
When I broke the screen of my Xiaomi mix 3, it was completely black, I sent it back to repair and they had no problem at all repairing it even if I didn't unlock it before sending it. (Maybe it's because Xiaomi has hw tests shortcuts in the bootloader?)
-
Sure, the manufacturer could, but they might not provide those kinds of images to their official repair centers, certainly not third-party ones.
-
They should provide it, easier to do compared to a mode that can't be activated if the screen is broken or simply the user has no idea how to do it.
For example Epson gives watermarked service programs to authorized service centers (splash screen says "licensed to Mr xxx of yyy inc." so they know exactly who leaked it)
Apple also has such secret software
This will also give a competitive advantage to official service centers (why pay $$$ for certification and training if can get the same tools of a generic store that opened yesterday?)

One UI has been crammed with features for years now, many of which would be very nice to have in Pixel phones. Maintenance Mode would be good, I guess, but I can think of several others that would be far more beneficial to have merged into AOSP in some form.
For example, One Hand Operation + is the best implementation of gesture navigation in all of Android IMO. It's quicker and more efficient than traditional gestures, more customizable, and plays well with third-party launchers. It's one of the killer apps that makes it hard for me to consider anything other than a Samsung phone these days, especially since Google has made no attempts at fixing the wonky behavior of the native gesture navigation and third-party launchers.

Google should be embarrassed at how much better Samsung is.

Let me know if you have any feedback about this article 😁
Full disk encryption?
Android hasn't used FDE for a couple of years now. File Based Encryption (FBE) has been required instead since Android 10. With FBE, each user has their own credential encrypted storage location for apps, which are encrypted with the credential from that particular user. (I verified this while testing. When you boot and unlock the primary user, other users data at /data/user/{id} is still encrypted until you unlock them.)
Pretty much my thoughts, yes.
In order for the FDE to have any usefulness, the key has to be derived from a secret that only the user of phone knows (I.e. a secret PIN, password or pattern)
