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.
If you want to go the AML SBC route, check out https://nexdock.com/
They are portable touch screen monitors, and if your lucky, its at most a USB + HDMI to get the touch screen working. They’ll also supply power to your SBC, which might help the portability aspect.
You can get similar portable monitors from Aliexpress as well.
Edit: just realised they now have WiFi. The nexpad has no WiFi, otherwise look for other portable monitors.
