Android 9 Pie update pushed on my phone again today


Hello all, first post here.

I have a S9 that got the Android 9 Pie update last week. I installed it as soon as I got the notification and it has been working fine for the last week or so.

This morning I got the same notification again. Reading through the description of the update, it seems an entire new re-install of Android 9, not just a patch on top of it.

When I run the update last week the installation completed succesfully and the phone is definitely on Android 9 Pie, with the new One UI, the dark theme, the annoying change to the GSP power options, etc. etc.

I do not understand why the update is being pushed again onto my phone.

Has anyone else experienced the same thing? Any of the moderators want to chime in?
