This is a Google Play Services update. For GrapheneOS users without GApps wondering: A similar feature is already built-in: https://grapheneos.org/features#auto-reboot

Heh, my first thought was “Don't they do this already?”, but apparently GrapheneOS was ahead of the curve there. Nice.

[illiac786]

Still ahead of the curve, as it can be disabled on grapheneOS while it apparently won’t bee possible in Android ;)

> GrapheneOS was ahead of the curve there

Not really. Samsung was the first with this, but their reasoning had absolutely nothing to do with security. It was because their phones slowed down over time and their solution was to give users the option to reboot it at specific intervals. You could even make the argument that the Samsung solution is still the superior solution because you get to set the interval.

How would an OS taking over your hardware would be ahead of the curve or nice?

> This is a Google Play Services update

As the GrapheneOS docs note, the feature is better implemented in init and not in system server or the app/services layer like Google has done here? Though, I am sure Google engs know a thing or two about working around limitations that GrapheneOS developers may have hit (in keeping the timer going even after a soft reboot, where it is just the system server, and the rest of the userspace that depends on it, that's restarted).

Huh, I have GrapheneOS and I never noticed it rebooting. (And when i manually reboot, the "BIOS" prevents it from booting without acknowledging that I'm aware it's a non-Google OS, so how does it work?)

[daneel_w]

The feature is not enabled by default. Also, the boot doesn't wait for you indefinitely - it just gives you a few seconds to glance the checksum and halt it, before it proceeds automatically.

[edent]

You don't have to acknowledge anything. The boot screen shows a warning which you can interrupt. If you don't do anything it'll continue to load as normal.

[morpheuskafka]

That’s weird. I wouldn’t expect Play Services to handle a system function like rebooting unrelated to any Google services.

[usr1106]

No. Play Services is Google's way to make Android closed source. Many new features don't get implemented in Android, but Play Services. Many apps don't work (correctly) without Play Services.

[ffpip]

Play services is how Google delivers many Android updates now so that all users can get security updates without waiting for the device vendor to publish it for each device.

Samsung has also had this feature for ages.

[SG-]

not for security tho, it was for bloat/fixing random issues like a typical Win95 daily reboot.

[NotPractical]

Typical lazy Ars reporting. The feature originates from GrapheneOS, not iOS.

[kernal]

No, the feature first appeared on Samsung phones to fix their bloat / slowdown issues. Now it’s suddenly a security feature.
