Is it me or does that screen look dubious?
Agreed.It does not look like any update I have ever received from Samsung. Also, what would "Update 11" be? I do not think it is a legitimate update.
Yes, I have Verizon and can confirm this. It's the January 2020 security update, so it is best to install it.This is how Verizon do their updates, so if you are with them, it's totally safe
