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
I took a look into those “toy” tablets in the 40 bucks price range, most of them seam to have a clearly visible Wireless chipset for wifi/bt, guess ima try to desolder and hope it still boots after.
If the chip isn’t bga then you can cut the pins, if it is a bga you can use a heat gun to get it to separate
I got a hotair soldering station ima try my best :D But i think most of the cheap ones arent bga but look like this one:
Why? What is your use case?
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 :/
Keeping the device turned on while the airplane is ascending and descending.
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.
