Hello,
if you are ok with a generic image, you can take the /e/ Android GSI. This is an image for many phones that support Project Treble: Device support (Project Treble)
These are actually all new phones that can unlock the bootloader and came with at least Android 8.1 out of the box.
However, some functions may work on one phone and not on another.
I use the Xiaomi Redmi Note 9pro, a top phone, with the GSI image. The fingerprint sensor does not work on my phone, which does not bother me because I do not want to use it anyway.
In the car, no reception strength is displayed, even if I have full Emfpang on the phone. However, phone calls etc. work. I do not listen to music via Bluetooth in the car.
Unfortunately, the GSI is not yet officially supported by the e foundation, but I hope that they will start sometime, then I must not always create :-). Currently, the computer next door also hums again to create images…
