@rhl120 said in what model number do I need for flashing on a pixel 3a and how does it differ from a pinephone:

Hi, I am very new to ubuntu touch and flashing roms on my phone in general and I would like to know what model number I should buy of the pixel 3a to flash ubuntu touch on it.

Please read https://devices.ubuntu-touch.io/device/sargo/ carefully! 🙂

Also watch out for carrier locked phones!
In some countries it's still a thing it seems... 😕

Other than the trivial differences between it and the PinePhone (like the specs, the kernel and the boot process), how does the pinephone and Google pxiel 3a differ when it comes to using ubuntu touch (do they both have the same functionality (at least theoretically)? can I install the same programs on both? etc)

It's like you would run Android on both of them : The same stuff runs on them but at a different speed! 😉

Good luck with the flashing stuff!
