The Pixel 6 was my last Pixel, and it probably will be for awhile. I’m all set on the Tensioner CPU and the very lackluster 5300 modem " same modem 6 through 8" and UFS 3 memory, Samsung is light years ahead on hardware. Install Nova launcher and deboat Samsung apps through ADB and Install Google apps, will give you near Pixel software experience. Plus I personally cannot stand the camera visor design. Maybe if the Pixel hardware gets better in the 9 I will go back but only time will tell.

Linux comes with a default firewall it’s called IPtables/NFtables, Just make sure that it’s on. Example I Ubuntu Sudo ufw enable.
