Mathematica on android phone

There is a Mathematica build for Raspberry Pi OS. In essence that is a version of Mathematica for Debian OS on ARM platform. I can verify that the following works:

1. Install Debian on Android using UserLAnd, which by default thinks it runs on arm64 architecture (I'm using an arm64 android device).
2. Add armhf architecture by running "dpkg --add-architecture armhf"
3. install Mathematica. apt install mathematica.deb file seems to be missing something, but I can force open the deb archive, and extract all files.
4. Mathematica runs.

No virtual machine is used here, so Mathematica is running natively on Android.
