Hi, I run the stock OS on my google pixel 6a.
I turn it off 2 days after the article came out
And turn it on again an update today (without sim card in the phone)

I have given my phone number out to a lot of different websites and apps

Should I flash my phone with Google rom or just keep using it and don’t be worried because I ain’t a high target individual

Well, do you have the March 2023 security update installed?
