It's possible to install the "real" openscad in the Termux app (pkg
install openscad), although that version's currently only 2019.05.
Latest version can be built from source though (but it takes quite a
while to build).

Either setup some X server and run the GUI, or (what I normally do) run
in headless mode and output preview to a .png / render a model, and view
those separately.

Note that the Termux app on the Play store is outdated, because it needs
to target an older Android API version (API > 28 disallows running
executables from data folder, which Termux requires), and the Play store
does not allow uploading such old-target apps anymore.
It's fine to install it via F-Droid though.

Termux can be downloaded directly from the F-Droid site, or it can be
installed using the F-Droid app (I'd recommend the latter, so you get
updates).

• Get the F-Droid apk from https://f-droid.org/, and install it. Open
  the F-Droid app, search  for "termux", and install it.
• Or alternatively, just grab the termux apk from
  https://f-droid.org/en/packages/com.termux/

See here for Termux info: https://wiki.termux.com/wiki/Main_Page

Open Termux; it will do a first-time setup. Then you should be good to go:
pkg install openscad
openscad --version

outputs 2023.01.11, looks like it's not outdated after all!

To create a model:
openscad model.scad -o model.stl

The binary openscad in termux unfortunately does not support .png output
(OpenCSG) or .3mf output. To get that, you'd need to build openscad (can
be done in termux too).

For Termux comfort, you may want to install a keyboard with arrow keys
and such. I like Hacker's keyboard:

I don't know if it works better (or at all) on Android, but you
could try one of the WASM versions, e.g.

Yesterday I tried both the approaches
With f-droid although latest version of openscad was installed, but could
not be of much use as there was no gui support and I have no experience
working with command line only.

Wasm somehow did not work

Finally found an app andronix in Google playstore

This has helped converting my samsung tab to a PC like experience with
ubuntu xfce.

Till now everything is working fine.

Openscad version in this is 2019 but there is no issue as I am working
through python and even the most complex models could be rendered without
any problem
