Does it exist? I hoped i would find some Android Based MP3 players without wireless and aux only… The only other options i found where some SBCs that support android like the AML-S905X-CC, but i assume its kinda finicky geting a Touchscreen working on them.
Nope
Closest thing is the Librem5, which had addon modems, so you could dismantle it and remove the bt/wifi/modem
The Librem5 would be perfect, if it wasnt for the price
You can also run Bliss OS on x64 desktop. Works well on my 2-in-1 ThinkPad L390 Yoga. It also supports ARM emulation to run ARM apps.
You can also rip out wireless stuff from many of those.
Android on PC sounds good, the power consumption would be high tho, and i would prefer a smaller form factor. But a old netbook mainboard + bliss OS could be small enough.
Waydroid on a linux laptop with the wifi adapter removed is option 2
