No Seamless Updates for S21 series

[Gary02468]

You should [bear] in mind that this feature exists in Android already. It takes no more resources to engineer around it than to keep it enabled. The work has been done.

Dunno. The article linked above (by XDA editor-in-chief Mishaal Rahman) says "OEMs don’t want to sacrifice a few gigabytes of storage space to support seamless updates" and "Another reason OEMs may have chosen not to implement A/B partitions is cost: Keeping up with Google’s constant changes to Android’s partition schemes requires a lot of effort".

I have no independent knowledge of these considerations, so I can't say whether Rahman's assessment is correct, but it sounds plausible to me.

It's been so long that I had forgotten about the lengthy app update times so yea, I'd prefer seamless

Seamless would be great. But I'm okay with this.

Don't know why Samsung's not doing it though.

But why would you WANT to wait 15 minutes when you shouldn't have to? Why invent the lightbulb when candles are fine why use a washing machine them there's a perfectly good bathtub in your house?

It's a better solution to a current technology.

You are a true Master of the Metaphor.
(I mean that as a compliment incase there is any doubt.)

1. A reboot with a non-seamless update can take 10-15 minutes. It's the same amount of time as it takes for "first boot" when you install a custom ROM.

2. It's not that a seamless update is less susceptible to corruption, it's that unless the update completed with no errors, the phone won't switch to the update. So the phone is still running on the last update and after 24 hours from the last attempt, it tries for an update again.

(I've only had one corrupted update - on a Note 3 - but Samsung doesn't consider corrupted updates as covered by the warranty, so you have to buy a new phone if you can't get the phone into download mode.)

it takes an A & B partitions for seamless updates. I guess Sammy doesn't want to show how much extra bloat they put on each device. I wonder how much that would eat into storage capacity having to duplicate the bloat on two partitions.

This is what the Treble Check - Treble Compatibility Checking App, from the Play Store states about the S21...

If I read it correctly, Project Treble is supported but not enabled and only partition A is in use.
