I tested it with a Pocophone F1.
The same error.
Other cell phones are not available to me.

I suggest using a more modern emulator from
and dragging a fresh current Companion into it if needed.
Sorry I don't understand your answer.
I use version 2.65u on the smartphone.
Isn't this up to date?
Frank
Your smartphone is up to date.
Your emulator might not be up to date., in its Companion or its O/S.
The stock MIT emulator can't run some projects.
Can you please send me a link to the current emulator.
If possible a 32bit version.
Thank you very much.
Frank
This is a more recent emulator
but it needs a sideload of the latest Companion:
http://appinventor.mit.edu.ezproxy.canberra.edu.au/ai2/ReleaseNotes.html
see FAQ Section: Companion and Emulator
for other emulator options.
I think this might be an issue with the USB connection, but I need to investigate.
