A thankyou to the help I've received here.
Phone looks and feels great.
Wallpaper (I'm pretty sure) is by Jubilee / 8Pxl
My phone is as Degoogled as I could get it with Lineage, & I don't use any banking apps on mobile, so I can't give too much info there.
For 2 factor Auth Apps, I use the Proton one and it works a treat!
Edit: Blerg!!! I have been having issues with the Proton Authenticator, You need Gapps or MicroG to get it to work properly.
Edit 2: Aegis works
