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.
Best bet is to buy a tablet device and then unsolder the radio
Nope
Closest thing is the Librem5, which had addon modems, so you could dismantle it and remove the bt/wifi/modem
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
Why? What is your use case?
Keeping the device turned on while the airplane is ascending and descending.
Sure, but a device with no radios is gonna be an uphill struggle to get anything useful onto as well. And airlines let you use a tablet/phone during ascent and descent right now, there is no need to remove the radios or use airplane mode anymore.
Audio Modem
So like an airgapped device? Have you considered getting a cheap off the shelf tablet and cutting the antennas? It wont connect to WiFi or BT anymore after that?
Cutting the antennas is far from removing the problem, even without antennas those chips still make a lot of noise in the 2.4ghz band. Id woud have the desolder the whole wireless chipset, i mean i have the soldering equipment for that, but i kinda doubt that a normal android will even boot after the Wireless chipset is gone :/
I’d say forget Android and just use a Linux board.
