Oh, that could be an explanation : I bought my S9 on /e/ store… but I understood (maybe misunderstood…) that you have to explicitly choose to use the dev version.
Thanks for the clue anyway 
Yes, when you buy your phone on the /e/store but for me who bought my phone outside the /e/store (with manual installation of /e/os) I have no access to the “dev” update.
Glad if I could help you ^^

OS updates don’t concern the data partition, so they should work regardless of any message about decrypting data.
What exactly does it say now for you in Settings - About phone - Android version (tap on it) - /e/ version?
Usually it was the other way around. Phones preinstalled with /e/OS had stable, the OS you could install yourself was dev. In the meantime, stable is also available on a few phones for installing it yourself.
And the Easy installer should install stable.
Android 10 dev is available for starlte … https://images.ecloud.global/dev/starlte/.

Yep, updates don’t concern data partition : that’s why the update worked.
The build number in the settings is long but has “userdebug” and “dev-keys,stable-release” in it. I can copy it right here, but only if you really want it 
In the update section I have the 0.23-20220401175185, which is not short either…
Maybe /e/ opened the update for a small period for 0.23 as they did for the upgrade to android 10?
That’s why I asked for Settings - About phone - Android version (tap on it) - /e/ version, which has all the necessary info in the same format like the filenames on the download pages … which isn’t short either, but leaves no questions open, and since Android 10 you can long-tap it and copy it to clipboard .
You’re on the stable release channel.

Thanks for the tip (the long-tap), good to know that!
I think the red message about data shouldn’t be there : when you see it, it’s too late to do anything anyway. And by the way, I didn’t encrypt my data partition… strange o_O
Thanks again for your help
Thank you for the precision, as you said it was the other way. 
But I cannot see the V0.23 dev. Maybe it is not available yet. Same when I check for update on the phone.
Now, when you check in Settings > Security, do you find that your phone is encrypted?
As a matter of fact I do… But I didn’t chose to encrypt my phone… And there’s nothing under users identifiers.
So TWRP is right, but I don’t know the password either…
TWRP has limited powers in an encrypted Samsung, so you noticed the warning about this. It seems at least a few people experienced this.
TWRP can still do some things … if it asks for a password, just press cancel. This applies defaut_password which is expected to have been applied.
/e/ users posts where they have experienced OTA Upgrade issues share the hashtag #ota-upgrade.

Great to know the cancel trick to apply the default_password!
And thanks for the link too.
You are right with that, it can be confusing if you don’t deal with TWRP for much else, but the bottom line for OS updates is that it’s harmless.
You can either ignore it, or if it really bothers you, you could try to install the /e/OS recovery provided on the ROM download page instead of TWRP.
(But I don’t have a Samsung device and even the manual OS install docs for starlte refer to TWRP when installing a custom recovery, so … pick your poison .)
Android did. In recent Android the data partition is encrypted by default. You can set your own decrypt method (password/PIN/pattern/…) for this by setting an unlock method for your lock screen.

… another user reported that if you change Settings > System > Developer options > Update recovery, to ‘yes’, then at your next update /e/ Recovery will overwrite the TWRP recovery.
I can live with it of course, as long as it doesn’t get me into troubles It’s just strange to see some kind of alerts about something you didn’t done… now, thanks to you, I know what this message means and where it come from. Again not a big deal : the phone works perfectly.
Didn’t know about the encryption by default on recent android.
Again, many thanks to you guys for your advices and informations!!

No OTA Upgrade for my Galaxy S9+ star2lte
Android version: 0.22-q-20220228166119-stable-star2lte
The phone is not from the e-shop and I have installed it with the easy installer.
From that information, you are on Android 10 q and you are on stable ! There is no further OS Upgrade available !
Are you referring to Touch sensitivity - #2 by Polli ?
No 0.23 OTA upgrade for my S8 Dreamlte (0.22-p) too.
My son received 0.23-q OTA on his S9.
The dreamlte stable build is yet to be released.
Hi, still not receive v0.23
Curently on 0.22-q-20220226166118-dev-starlte on my samsung S9
Curent build e_starlte-userdebug 10 QQ3A.200805.001 eng.root.20220226.001011 dev-keys,dev-release
Why I can’t have update, it seems other people with the same phone have already access to the v0.23.
Is it something that i have missed ?
Thank for any help/explanation
