How to back up android call block list?

I’m rooting my lg v20 soon as the root is near completion and I just had the panickitg thought of the title above. I have blocked a total of 300 spam numbers now of miicrodoft veendows, timeshares, fucking chase bank, and I DO NOT WANT TO LOSE THIS BLACKLIST.

So. Wat do?

Maybe LGUP copy’s that data?

Hmmm. Maybe I’ll just keep a twrp backup of my rom in case I get call flooded again.

twrp, good one, if you can just find where the file is stored you can backup and restore with twrp without a complete backup

I think it’s android universal not an LG thing
